I don't like clicking back to the menu, I like flipping through things... Thanks for the work, appreciated. Mark Kaehny (Done -- good suggestion. --Editor) _________________________________________________________________ Date: Thu, 05 Sep 1996 13:22:23 -0700 Subject: Linux trademark issues. From: Earl Stutes estutes@palladium.corp.sgi.com Yet again, it appears someone is attempting to make a buck on something that most of the rest of us feel should be a free or at least public domain thing. In this case the word Linux. I don't have any suggestions as to how "we" deal directly with this issue, but I certainly hope that all of you folks that are a part of the growing Linux commercial community will take the lead in fighting this yo-yo. Of course part of my contribution to support you is the fact that I buy the magazine from the newstand(fatbrain.com, actually) every month. I have enjoyed your magazine right from the beginning, and will continue to be a supporter over the long term. Thanks for listening =eas= (Since the Gazette is strictly on-line, I'm assuming you are talking about the Linux Journal when you refer to buying the magazine. Latest news about the trademark can be found by clicking the Hot Linux News button on the Front Page. There are also couple of items in the current News Bytes section. --Editor) _________________________________________________________________ Date: Fri, 6 Sep 1996 08:58:23 +0100 (BST) Subject: LG Issue #9 From: Dave Pearson davep@hagbard.demon.co.uk Hi. First, I'd like to say congrats on taking over support of the LG, it's a very handy resource and it's nice to see it getting continued support. However, I've got a question about how you are going to handle it. In the past I've always downloaded a copy of the latest issue of LG and installed it on my own machine so that I could read it at my leisure. IIRC, each issue included a new top level index file that would list the TOCs of all issues, this ment it was simple and easy to install and to quickly search for a specific article. Correct me if I'm wrong, but issue 9 does not appear to follow this install style. Was there a reason for this? Thanks for your time. -- Take a look in Hagbard's World: | w3ng - The WWW Norton Guide reader. http://www.acemake.com/hagbard | ng2html - The NG to HTML converter. Resist UK Internet Censorship: | eg - Norton Guide reader for OS/2. http://babylon.ivision.co.uk | dgscan - DGROUP scanner for Clipper. (You are not wrong. I did change it, not realizing what a hassle it was going to cause some people. The reason for part of the change that will most likely remain, is that I wanted to be able to keep issues 1-8 exactly as they were when John put them out -- i.e. not changing the front page, etc. The way it works now should not be that different. The front page offers a spot to click for the TOC of issues 1-8 and a spot for TOC 9. When 10 comes out next month, it will be on top of TOC 9. I personally thought that having each TOC in a separate file would make it easier -- perhaps I was wrong, it's been known to happen. I'm considering a search program, when I have time to set it up, and in the meantime, I will add an index containing all TOCs. --Editor) _________________________________________________________________ Date: Fri, 6 Sep 1996 06:30:39 -0500 (CDT) Subject: new LG issue From: Larry Ayers layers@vax2.rain.gen.mo.us Last night I saw the new LG issue on the SSC website. So evidently in the last week of August writers came through for you. There are some great articles in issue 9; an auspicious beginning for SSC's sponsorship (and your editing duties). By the way, I got an email the other day from another LG reader, complaining that the graphics from the TkDesk article I wrote in LG #8 were not accessible to a web-browser. I loaded the article into Netscape (from the SSC website) and found this to be true. Perhaps the directory structure was changed somehow when LG #8 was put on the site, rendering a link inactive? I just checked issue 8 again, and found that most of the inline images in my pieces won't display. I think the problem is that the directory which John Fisk used was ./gx/ayers, whereas it looks like SSC's gazette graphics all go in ./gx. Regards, Larry Ayers (Thanks. Yes, authors did come through for me, including you, and I thank you all. Sorry, I know about the problem with the links, and it is now fixed. The directories were set up correctly; there were just a lot of missing files. --Editor) _________________________________________________________________ Date: Fri, 6 Sep 1996 10:25:43 -0700 (PDT) Subject: Re: Linux Gazette Issue #9 From: schuld@btv.ibm.com (David W. Schuler) I just tried to take a look at the Linux Gazette Issue #9. Unfortunately, I did not find the "I'll read it myself" button at the top of the index that would allow me to see the whole thing at one time and print it out for later reading at home. I would appreciate if you could add this option back, rather than causing me to have to go into each section to print it out so that I can read it later at home. Thanks. David W.

I was wondering if you have an archive with the past issues of the Linux Gazette(tar-ed and gzip-ed) so that us (the readers) can download and browse at our leisure? If not, would it be too much trouble to do so? I hope I'm not imposing too much, but I am on a shared phone line, and much as I would like to stay on the net all day (it's tempting), I can't. Thanks for *any* help! --Sunit Das (No problem. tar files are available, I've just been having technical difficulties -- they were unreadable. At any rate John Fisk sent us new files that are now up at ftp://ftp.ssc.com/pub/lg/. Also, our issue 10 file, lg_issue10.tar.gzp and all issues (1-10) file, LinuxGazette_oct96.tar.gzp are located at that site. --Editor) _________________________________________________________________ Date: Tue, 10 Sep 1996 23:05:36 +0200 Subject: Suggestion: Search Engine From: "Johannes Norinder" dante@inferno.skurup.se My suggestion is that you ought to have some kind of simple search engine so that you easily can search for phrases within one or all of the issues of LG. As is it's hard to know if you've covered Iomegas Zipdrive, for example. Otherwise thanks for a great service. Johannes Norinder (I agree. In fact it's something that I have already thought about. There is a search engine for Linux Journal, and I will probably use the same one for the Gazette. However, it means doing a lot of front end work to get it set up. When I'll have time to do this is not certain, but it is definitely on the list. --Editor) _________________________________________________________________ Date: Wed, 11 Sep 1996 00:32:27 -0400 Subject: my 2 cents From: "Aaron L. Hastings" alhastin@mtu.edu hey there im just gettin into linux i got it to help me learn unix which it has helped a lot on but i have found it to be totally awesome in its own right it is almost cliche but nothing in any commercial sense has managed to pull together in a near utopian ( except for bugs ) environment a cooperative effort of people worldwide it just shows what people can do when they work together ( like i said cliche but rarely achieved ) well this site is just another example of this cooperation YEAH (shades of e e cummings --editor) _________________________________________________________________ Date: Wed, 11 Sep 96 12:36:54 -0400 Subject: Linux Gazette From: Bill Cronk bcronk@nvl.army.mil I am very glad to see a new issue put out. I was sad thinking that it had gone by the wayside. I would like to see a section of tips and tricks devoted towards the novice user who needs to learn the tricks to setting up hardware, software and all the other things that come along. I remember when the first Byte magazine came out and for the longest time there were articles on hardware and software for the novices. After a while that ended as people grew up and demanded more in depth articles. I would think that most people would have a hard time finding those back issues. In the case of the Gazette all the back issues will most likely be archived and if a basic index was published once or twice a year many new people to the world of Linux would have all kinds of useful tips and tricks to read through. Either way I enjoy reading the Gazette and will look forward to new issues. I wish you success in publishing the Gazette. In the future, maybe the far future, I will be able to provide an article now and then on some hardware and software items related to laboratory instrumentation interfacing and controlling of automated test equipment.

I would like to set up a personal mirror of all issues on a DOS machine that I use regularly but unTARring the files from the FTP site is fruitless because the filenames are made DOS compliant and the links no longer match what is in the directory. I basically want my "site" to exactly mirror the SSC pages. Thanks for any help you can provide. GVL II (Sorry, but no. Frankly, this is quite an unusual request, since most of our readers do use Linux boxes. Love to have you mirror us, but this is more work than I have time for.

See: http://www.linuxjournal.com/Morelj/cool.html What is a very pleasant surprise is to see that logo starting to appear in the mainstream trade press. On page 41 of the September 16, 1996, InfoWorld, is a half-page Equinox ad for their multiport serial cards. The COOL logo is the first one displayed, before Windoze, Novell, or SCO. ------------------------------------------------------------------------ Paul Bingman paul@edgewood.net Voice +1 503 222 3846 Edgewood Engineering http://www.edgewood.net FAX +1 503 223 3071 WWW/CGI, Internet, Linux, application software, firmware, device drivers ------------------------------------------------------------------------ (Cool. --Editor) _________________________________________________________________ Date: Fri, 13 Sep 1996 16:00:12 +0000 Subject: LG : french translation + mirroring ? From: Patrick Mevzek To: fiskjm@ctrvax.Vanderbilt.Edu Hi, I discovered your Linux Gazette some months ago, and it's great and very interesting. I've discovered Linux a little before, because I will need to install here at my school (you know I'm only a student like you ;-) !!) a small LAN of computers for students, with PC (Win 95) and one LINUX-PC (which will be a firewall-mailhost-webserver, etc...). So I'm quite interested with everything in relation with Linux. In fact, I can propose you to translate the LG in French. I would be very pleased to do that. But I can promise you I will always have enough time to do it quickly, because first I'm a student, and therefore I've exams, (you know that...), and second, like I said before, I have to work a lot to install students'LAN. So, let me know if I can help you that way !! BTW, because I will be the maintainer of the web server of the students too, it could be possible, somewhat in January or February 97 to start mirroring the LG, here at the ESPCI. I can't promise you big things, because mainly in 3 years I won't be in that school anymore, and I can't say that the next webserver maintainer will keep mirroring LG !! I hope to hear from you soon Regards, ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~ Patrick Mevzek Patrick.Mevzek@Info.Escpi.fr ~ ~ HomePage (co-developer): http://www.geocities.com/Paris/4206 ~ ~ 'I like these calm little moments before the storm...' ~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ (Glad you like the magazine. John Fisk forwarded your letter to me as SSC is now handling the Linux Gazette. I think it would be wonderful if you were to translate the LG into French, whenever you have time. It would certainly give the Gazette a wider French audience. We have very liberal copying requirements, especially if you are a mirror site (virtually none). We always welcome another mirror. Thanks for your interest. -- Editor) _________________________________________________________________ [ TABLE OF CONTENTS ] [ FRONT PAGE ] Next This page written and maintained by the Editor of Linux Gazette, gazette@ssc.com "Linux Gazette...making Linux just a little more fun!

I found an *OLD* way of interfacing C program with Tk scripts, which is not documented in Welch's Book. What is it? Pipe! My C prog (parent) create two pipes to communicate with the Tk prog (child). The Tk prog only need to use stdin and stdout without knowing that this is controlled by the C prog. This provides a much easier way than the interface procedures described in Welch. Attached here are my C prog and my Tk prog. If you think this is worth writing a full article, please let me know. I will do that for the Gazette. :) Cheers Liang-Shing Ng Description: simple C and Tk prog pair showing how to read/write with each other. example of use: C may use this Tk for graphical interface. C does some image processing, then ask Tk to display it.

Using vi or emacs is great, but if you have more than one file, you can do this: perl -pi.bak -e 's/\r//g;' filelist FYI. ----------------------- Jonathan Specialized Systems Consultants, 206-782-7733 "A jewel mine of courtesies and a living casket of diplomacy" __________________________________________________________________________ ANOTHER EMACS CONTROL M TRICK Date: Thu, 05 Sep 1996 13:34:09 -0700 From: Earl Stutes Subject: $.02 emacs tip Here is the way I handle the ^M in files. Put this in your .emacs: (defun dos-unix () (interactive) (goto-char (point-min)) (while (search-forward "\r" nil t) (replace-match ""))) (defun unix-dos () (interactive) (goto-char (point-min)) (while (search-forward "\n" nil t) (replace-match "\r\n"))) IP don't usually bind these to keys, but you certainly could. When you call the function M-xdos-unix, it will delete all of the delete all of the characters in the file. And of course the other function will put them back. =eas= __________________________________________________________________________ X TERM TITLEBAR FUNCTION Date: Fri, 06 Sep 1996 17:53:00 -0600 From: "Michael J. Hammel" Subject: Gazette #9 comments -- xterm title bar function Nice job on the new Linux Gazette! I'm just scanning it and had a few notes I thought I'd pass to you. In the mail, there are a couple of things. Jim Murphy says that the "-print" option to find is necessary to get output from the find command and follows that up with "get used to it, its *nix". Well, he's part right. Linux does require this. However, any users who work on other Unix boxes will find slight differences in some of the common CLI commands (CLI is "command line interface"). For example, "find" on Solaris does not require the -print option to get output. Just food for thought. Second, I have an xterm title bar function that people might find useful. I'll give the code first, then explain what it does: In your .bashrc (or .kshrc - note this only works on ksh style shells) add the following: HOSTNAME=`uname -n` if [ "$TERM" = "xterm" ] && [ "$0" = "-bash" ] then ilabel () { echo -n "^[]1;$*^G"; } label () { echo -n "^[]2;$*^G"; } alias stripe='label $HOSTNAME - ${PWD#$HOME/}' alias stripe2='label $HOSTNAME - vi $*' cds () { "cd" $*; eval stripe; } vis () { eval stripe2; "vi" $*; eval stripe;} alias cd=cds alias vi=vis eval stripe eval ilabel "$HOSTNAME" fi This does three things (as long as you're in an xterm and running bash): 1. when the xterm is first opened, the name of the current host is displayed in the title bar. 2. when you cd to a directory, the current path is displayed in the xterm title bar with the users $HOME directory stripped off the front end of the path (to save some space when you're somewhere in your own directory tree). The path is preceded by the current hosts network name. 3. when you use vi to edit a file the name of the file is displayed in the title bar along with the current hosts name. When you exit your vi session, the title bar reverts to the "hostname - path" format described in #2 above. I found this very useful for all my ksh based systems because it removed the path from my shell prompt, thus saving me space for prompt commands. Since bash is a ksh compatible shell, this works quite well on standard Linux systems. Hope everyone finds this useful. -- Michael J.

Jeff Blaine __________________________________________________________________________ MORE X TERM TITLE TRICK 2 Date: Sun, 08 Sep 1996 23:38:31 -0500 From: the Edward Blevins Subject: Re:XTerm Title Trick 2 In issue #9 of LG, one of the two cent tips is about how to put the hostname in the title of your xterm. It mentions precmd for csh, but not the bash equivalent. The way I do this in bash is as follows: if [ $TERM = 'xterm' ] then export PROMPT_COMMAND='echo -ne "\033]2;"`whoami`@`hostname`"\007"' fi this can just go in your .bashrc, lots of fun. I add the whoami, because I am a sysadmin, and its a convienient way to tell if I am root, in addition to the '#' on the prompt. Another variation I use sometimes is : "`whoami`@`hostname`:`pwd`" then I can remove the path from my prompt. ps the LG is GREAT! Keep up the good work. Thank you very much! -- the Edward Blevins thedward@mail.utexas.edu __________________________________________________________________________ BASH QUICK TIP Date: Thu, 12 Sep 1996 14:59:41 +1000 From: Jeremy Laidman Subject: Bash Quick tip Issue 8 had a 2c tip "There and Back!" describing a neat way to change between two directories quickly. The method was to use "cd ~-" which will set the working directory to the previous one you were in. Bash (and several other shells I've tested) will do this without the tilde, ie "cd -". This saves me two keystrokes (including the shift key).

If you're like me, you make an attempt to keep your Red Hat system current- at least, in some respects. Tonight, looking at a man page which mentioned Linux 0.99.11 brought to mind the thought that I should upgrade my aging Red Hat 2.0 installation to something more current; fast on its heels was a curiousity about just what I have taken from where. So with a little bit of shell-play and some suggestions from my friend, the following was produced: rpm -qai | grep Dist | awk -F': ' '{print $3}' | sort | uniq -c This will tell you all the distributions you have installed RPMs from, and the number of RPMs from each.

Hi Jim Murphy. Saw your "find" tip in issue #9, and thought you might like a quicker method. I don't know about other distributions, but Slackware and Redhat come with the GNU versions of locate(1) and updatedb(1) which use an index to find the files you want. The updatedb(1) program should be run once a night from the crontab facility. To ignore certain sub-directories (like your /cdrom) use the following syntax for the crontab file: 41 5 * * * updatedb --prunepaths="/tmp /var /proc /cdrom" > /dev/null 2>&1 This would run every morning at 5:41am, and update the database with filenames from everywhere but the subdirectories (and those below) the ones listed. To locate a file, just type "locate filename". The filename can also do partial matching. The search only takes a few seconds typically, and I have tens of thousands of files. The locate(1) command also has regular expression matching, but I often just pipe it through agrep(1) (a faster grep) to narrow the search if I want. Thus: locate locate | agrep -v man ..would exclude the manpage for example, and only show me the binary and perhaps the sources if I had them online. (The -v flag excludes the pattern used as an argument.) Or the binary alone along with a complete directory listing of it with the following command: ls -l `locate locate | agrep bin` The find(1) command is a great "swiss-army knife" (and actually not that bad once you get used to it), but for the 90% of the cases where you just want to search by filename, the locate(1) command is *far* faster, and much easier to use. -- Bill Duncan, VE3IED | BeachNet --> http://www.beachnet.org bduncan@BeachNet.org | - Network/System Administration bduncan@ve3ied.uucp | - Web Design, Hosting Services +1 416 693-5960 | - System Analysis/Design/Programming __________________________________________________________________________ PICO CONTROL M TRICK Date: Sat, 14 Sep 96 09:28 PDT From: Peter Subject: Easier ^M removal with Pico I've been using this trick for a long time .. its a lot easier then defining macros in Emacs, too. All it requires is a recent copy of the Pico editor. Load the file you wish to strip ^Ms from, make a small change in the file (like hitting the space bar, then delete), and save it. No more ^Ms! Peter __________________________________________________________________________ YET ANOTHER EMACS CONTROL M TRICK Date: Tue, 24 Sep 1996 19:26:10 -0700 From: Dan Gunter Subject: re: emacs ^M trick I'm new to emacs, so I use a very simple trick to search & replace on special characters: I cut or copy them into the paste buffer, then Meta-% and hit Control-Y to yank them back into the minibuffer. This isn't elegant, but it's very easy to remember, and seems to work for everything. __________________________________________________________________________ [ TABLE OF CONTENTS ] [ FRONT PAGE ] Back Next __________________________________________________________________________ This page written and maintained by the Editor of Linux Gazette, gazette@ssc.com "Linux Gazette...making Linux just a little more fun!" _________________________________________________________________ NEWS BYTES _________________________________________________________________ CONTENTS: * News in General * Software Announcements _________________________________________________________________ NEWS IN GENERAL _________________________________________________________________ LINUX TRADEMARK: LET'S FIX IT. From: Paul Bingman paul@edgewood.portland.or.us As you are no doubt aware, some (insert your favorite deragatory epithet) has trademarked the name "Linux" is now out trying to collect from everyone they can. An intellectual property attorney friend of mine, G. Gervaise Davis III, is offering to get this trademark killed pro bono, if we can cover the expenses. His opinion, not having seen the original papers filed for the trademark, is that the original has absolutely no legal standing, and will probably be killed by the U.S. Patent and Trademark Office as soon as we make the proper legal moves. Please forward this email to anyone/everyone. I'm especially interested in hearing from anyone who has received a collection letter, and also from Linus or someone else who can direct us to where the trademark should rightfully go. Also, this effort should be coordinated nationally or globally. _________________________________________________________________ MESSAGE FROM WORKGROUP SOLUTIONS September 19, 1996 Mark Bolzern, President WGS Member Board of Directors, Linux International With regard to the attack made on WGS, as well as the Greater Linux Community by William R. Della Croche claiming that he owns the Linux Trademark... There is no way this is true. We have retained an attorney and will be making a public announcement soon that benefits the entire Linux community. Thousands are aware of this situation, and have offered to help. The best help you could give us, is to see if there is something we offer in our Linux Shopping mall that you would like to own, and if so buy it. We add new products almost daily. If you don't see what you want, ask, or refer a friend to us. Thank you!

By "Enterprise Computing" I mean what the big companies mean: large systems, high availability, high performance and "industrial strength" in general. Currently, topics include: * Databases * Clusters/SMP * Configuration Mangemet * WAN Internetworking, incl Frame Relay and X.25 * Network Mangement and Administration * Disk Mirroring and RAID * Fault Tolerance The pages can be viewed from http://204.157.166.19/linux/index.html Additional information: Linas Vepstas, Lamebrain Enterprises linas@fc.net _________________________________________________________________ LINUS NEWS Pablo Kiryluk of GM Communications, InterSoft's RRPP, writes: Linus Torvalds, the Finish guru creator of the operating system "Linux" landed in Buenos Aires, Argentina, to the expectation of many. Invited by InterSoft, the multinational software producer, Mr. Torvalds lectured to a wide range of public about the "Software Free" concept, its relation with Internet and Linux' characteristics. The range of ideas spread by Linus Torvalds in Argentina where laid out in terms of "knowledge sharing" and "composing from different creators". "Company's tendencies will integrate parts of free software forming a system to curb the commercial industry of software" --substantiated Mr. Torvalds. Also, the concept of "the idea that technology were humanity' patrimony, based on the free distribution of software and its source codes" was expressed in several occasions. Also, Torvalds decided also to introduce "Scriptum", the first adaptable editor to different Linux' environments, created by InterSoft. Scriptum was created in Argentina and developed as a powerful tool capable to run of different platforms and offer several features. With Scriptum, almost the entire working environment can be configured, totally integrated to RCS/SCCS tools and UNIX (grepp, diff, etc.) and powerful navigation commands to find sources, data and documents. _________________________________________________________________ MORE LINUS NEWS The San Jose Mercury News published an interview with Linus Torvalds on September 8, 1996 in which Linus is quoted as saying Microsoft operating systems are bad, and their morals are even worse. But they make some good applications. Check it out in Section E of that newspaper, or web site: http://www.sjmercury.com/business/finland/torvalds.htm _________________________________________________________________ SOFTWARE ANNOUNCEMENTS _________________________________________________________________ SOFT BRAILLE FOR LINUX: BRLTTY 1.0.1 The official release of BRLTTY, a software system to allow access to the console of a Unix system for users of soft Braille displays, has been announced. BRLTTY currently runs under Linux (kernel version 1.1.92 or later) on a PC or DEC Alpha. The package has been uploaded to sunsite.unc.edu in the directory /pub/Linux/Incoming. It is expected to move to /pub/Linux/system/Access at some later date (please note the move from /pub/Linux/utils/console). FEATURES * Full implementation of the standard screen review facilities. * A wide range of additional optional features, including blinking cursor and capital letters, screen freezing for leisurely review, attribute display to locate highlighted text, hypertext links, etc. * `Intelligent' cursor routing. This allows easy movement of the cursor in text editors etc. without moving the hands from the Braille display. * A cut & paste function. This is particularly useful for copying long filenames, complicated commands etc. * An on-line help facility. * Support for multiple Braille codes. * Modular design allows relatively easy addition of drivers for other Braille displays, or even (hopefully) porting to other Unix-like platforms. Additional information: Nikhil Nair: founder of the BRLTTY project and author of the Tieman B.V. CombiBraille driver. mailto:nn201@cus.cam.ac.uk Nicolas Pitre: Author of the driver for the Alva series. nico@cam.org Stephane Doyon: Author of the driver for the TSI displays (Navigator and PowerBraille 40), doyons@jsp.umontreal.ca _________________________________________________________________ FIDOTOOLS Nickolay Grygoryev of SPb State University announced another FIDONET-related package called FidoTools.

Introducción Hola futuro contertulio con feddi y bt :-) Si te has decidido a instalar este paquete, toda mi enhorabuena. No es muy complicado, sólo puede que tengas problemas de permisos. Los fuentes incluídos en este paquete ya han sido parcheados para que funcionen un poco mas fino. Tanto fmbedit como bt tienen pequeños problemas, no seas muy criticón y piensa que no has pagado nada por ellos. Contribuye, si corriges errores, no te los quedes para ti, compártelos, envíame parches o comentarios, de esta forma haremos que este soft vaya a más. Un consejo: no lo uses desde X, la base de datos de terminales no está muy fina, me he propuesto corregirla, seguro que un día lo pondré como parche :-) (Antes decía que sería el próximo :-DDDDDDDDDDD) Tengo que agradecer : * Alfonso Belloso : 2:344/17.2 (si me acuerdo bien) * Jose Luis Sanchez : 2:346/207.17 (Este seguro) * Pablo Gómez : 2:341/43.12 (Correcciones en este fichero y los scripts para la automatización del área personal) * Javier Ruberte : 2:346/401.50 * Jose Carlos Gutierrez : 2:341/45.17 (Scrits de compilación de nodelist) * Carlos Terrón : 2:345/402.23 (Parche para que ftoss reconozca mayúsculas/minúsculas) Al final de este fichero encontrarás unos cuantos mensajes, todos enviados con feddi, con algunos trucos. _________________________________________________________________ Anterior Siguiente Indice Anterior Siguiente Indice _________________________________________________________________ 3. Instalación del FEddi 3.1 Instalación del usuario fido. Vamos a instalar fido como usuario de correo, puedes darle otro nombre. Entremos en materia. En este documento cuando veas ~/ se refiere al home del usuario. * fichero /etc/passwd Incluye la siguiente línea : fido::2004:300::/home/fido:/bin/bash * fichero /etc/group Incluye la siguiente línea : fido::300:uucp,fido,root 3.2 Paquetes necesarios Necesitas : * perl, haz ls /usr/bin/perl Si no existe, instálalo, discos D * ncurses, haz ls /usr/lib/libncurses.a Si no existe, instálalas, discos D 3.3 Configuración/instalación del mailer. Vete al directorio /FEddi-0.9pl5 1. Edita el fichero Makefile, en la variable SRCDIR pon el path donde estén tus fuentes, ej: SRCDIR=/root/trabajo/mailer/FEddi-dev 2. En la línea NODEPRG = añade al principio nlfunct.o sino, no compila. 3. make 4. Si tienes este error : ncurses.h: No such file or directory Haz : ln -s /usr/include/ncurses/curses.h /usr/include/ncurses/ncurses.h 5. su root make install exit 6. Parece que la utilidad de instalación no copia las utilidades a su directorio, haz lo siguiente : cp utils/* ~/fnet/utility 7. Hay que modificar unos cuantos ficheros : + Fichero printmsg #!/bin/sh cat | $HOME/fnet/utility/formatmsg | lpr + Fichero exportmsg #!/bin/sh if test $1 = "new" then cat | $HOME/fnet/utility/formatmsg > "$2" else cat | $HOME/fnet/utility/formatmsg >> "$2" fi 8. El directorio fnet se compone de lo siguiente : ./outbound ./msgbase ./copy ./log ./inbound ./utility ./nodelist Créate esos directorios y haz lo siguiente: chown -R fido.fido fnet 9. Fichero de configuración ~/.feddirc: + Permisos 644 + Usuario/grupo fido.uucp ; ; This .feddirc was automatically created with config.user ; ; Profile Section ; PROFILE Manuel Soriano 2:346/207.punto Nombre_de_net el_passwd outbound 2:* 25:946/100.punto Nombre_de_otra_net el_passwd outbound 25:* 93:346/101.punto Otro_nombre_de_Net el_passwd outbound 93:* END ; La pimera linea es tu direccion principal, las siguientes son sub-redes, el ; routado de la 25: y 93: se hace por la 2: ; ; ; ; Paths ; MsgBasePath ~/fnet/msgbase/ InboundPath ~/fnet/inbound/ OutboundPath ~/fnet/ UtilityPath ~/fnet/utility Log ~/fnet/log/feddi.log 200 CopyPath ~/fnet/copy/ NodelistPath ~/fnet/nodelist/ ; ; Misc ; Packer /usr/bin/zip -q -m -k -j %s %s ; Editor /usr/bin/vi %s Beep Yes AutoDelEmpty Yes KeepPKT No KeepNL Yes KeepBackups No ShowAllAddr Yes MaxMsgLength 64k QuoteLength 70 ReplySubject No AskForOrigName Yes AutoNextFolder Yes ; ; End of .feddirc ; Puedes basarte en este fichero para configurar el tuyo, a mí me funciona sin problemas. 10. Fichero ~/fnet/nodelist/fnlcrc dial 34-6- 3 dial 34-6 dial * pointlist ptlstr34 pointlist eu_punto nodelist region34 nodelist eu_nodos dial : Según tu zona 34-6 (Valencia), 34-1 (Madrid), 34-3 (Barcelona), etc... Con pointlist las diversas listas de puntos, se pueden usar las listas de punto que nos vienen de las bbs sin transformar. Con nodelist las diversas listas de nodos, se pueden usar las listas de nodos que nos vienen de las bbs sin transformar. Nada más. 11. Compilar las nodelist/pointlist Yo uso los siguientes scripts, son sencillos y funcionan. + fichero ~/fnet/nodelist/compila0 permisos 777 #!/bin/bash unzip lista.zip mv EU_NODOS* eu_nodos mv EU_PUNTO* eu_punto mv PTLSTR34* ptlstr34 mv REGION34* region34 mv SNETLIST* snetlist mv SUBPTLST* subptlst + fichero ~/fnet/nodelist/compila1 permisos 777 #!/bin/bash rm fnlc.* fnlc Esto te compila las listas, si tienes problemas seguro que son de permisos, revisa tus ficheros, normalmente los binarios se instalan en /usr/bin 3.4 Comprobación y manejo. Prueba de correo, Busca un paquete de correo que tengas por MS/DOS lo pones en el directorio ~/fnet/inbound y haces ftoss ; futility pack ; futility link Es de esta forma que tratarás siempre tu correo en entrada, ftoss crea automáticamente los folder correspondientes a tus áreas. fmbedit Si todo va bien tendrás el correo correspondiente a ese paquete en tu pantalla :-) El editor es muy sencillo y muy bien documentado, se parece un poco al editor del fmail. Creas un mensaje en un área o dos y haces : fscan Es de esta forma como tratarás siempre tu correo en salida. _________________________________________________________________ Anterior Siguiente Indice Anterior Siguiente Indice _________________________________________________________________ 4. Instalación del Binkley. 4.1 Configuracion/instalacion del caller 1. Lo primero que tienes que hacer es : vete al directorio /bt haces make su root make install deberás tener en /usr/bin: -rwxr-xr-x 1 root fido 238983 Sep 15 18:04 /usr/bin/bt y en /usr/lib/binkley: -rwxr-xr-x 1 root root 742 Sep 16 10:04 binkley.cfg -rw-r--r-- 1 uucp root 108 Sep 16 10:10 binkley.day -rw-r--r-- 1 root root 12332 Sep 15 16:20 binkley.lng -rw-r--r-- 1 uucp root 124 Mar 20 2029 binkley.scd -rwxr-xr-x 1 root root 14423 Sep 15 16:20 btctl -rwxr-xr-x 1 root root 13813 Sep 15 16:20 btlng -rwxr-xr-x 1 root root 15649 Sep 15 16:20 english.txt -rwsr-xr-x 1 uucp fido 1603 Sep 15 16:20 fido-toconv 2.

Incluye la siguiente linea en tu ~/.profile export BINKLEY=/usr/lib/binkley haz . ~/.profile (esto sólo lo harás esta vez, la próxima vez que entres como fido ya tendrás la variable BINKLEY inicializada) 4. Ejecuta bt 4.2 Problemas Si tienes problemas, seguro que son de permisos o path mal definidos, revísalos. 1. El error más común es : cannot re-open logfile El propietario normalmente es : usuario.uucp. Los permisos : 664 2. Otro error bastante común : Aquí te puede pasar que el tty que le has habilitado no tenga permisos adecuados, sobre todo si éste ha sido usado por el getty, normalmente debe tener permiso de lectura/escritura para todo el mundo. El error es : tty port can not be initialised Solución: chmod 666 /dev/ttyS0 o ttyS1; (COM1: o COM2:). 3. Para los que tengan RedHat : ln -s /var/spool /usr Si te aparece una pantalla parecida al frodo puedes hacer lo siguiente : ALT-Y, llamará a tu bbs, dejará tu correo y cogerá el que tengas en ella. Luego sólo tienes que ejecutar los comandos, ya vistos, para tratar el correo. Si durante la transmisión del PRIMER fichero tienes la impresión de que se queda ``dormido'', aprieta la tecla ESC y se ``despertará''. 4.3 ``Templates''.

He estando haciendo pruebas para conseguir lo del RE: con el soft de Linux y ya he bajado mi primer fichero. Paso a explicar como lo he hecho por si sirve para alguien y ademas por si lo hago mal que alguien me pueda corregir. Primero escribo un Net normalmente a mi Sysop. Cuando he terminado de escribir el mensaje salgo de el (Alt+x). Estando sobre el mensaje, pulso (Alt+g) y se me abre una ventanita que presenta unos datos.

Bien, desde hace un tiempo estamos venga a darle vueltas a la posibilidad de disponer en FEDDI de un area personal que permita recibir en ella los mensajes dirigidos a nosotros, recibidos en cualquier area, y sobre todo (ya que lo anterior no es complicado) el poderlos responder comodamente, enviandolos 'de regreso' a sus areas originales. Con estos script que siguen, al menos Francisco Jose Montilla y el que suscribe lo hemos conseguido. En primer lugar, se trata de crear el area que luego va a servir como PERSONAL. Esto se puede hacer del siguiente modo: (Como usuario fido) $ cd ~/msgbase $ mkdir +PERSONAL $ cp +R34.LINUX/* +PERSONAL/ (PERSONAL es el nombre que quereis dar al area personal) Comprobad que los permisos y dueños del nuevo directorio y los archivos que contiene son iguales a los que teneis en otras areas. Corregidlo si no es asi. Despues, de cara a vaciarla de mensajes, haced: $ futility "+delete" "all+" PERSONAL $ futility pack PERSONAL Si volveis a invocar fmbedit, vereis que teneis un nuevo area, llamado... PERSONAL! :-) Magia? :-) Ahora ya tenemos la base. Siguiente parte: Copiar los mensajes que llegan al sistema, nuevos, y a nuestro nombre. Esto se hace (casi) automaticamente. Si creamos un archivo asi: ,,, (o o) File: ~/msgbase/tosspath ---*reiss*------*schnippel*------oOO--(_)--OOo-------*knabber*-----*fetz*--- copy t"Pablo Gomez" PERSONAL ---*reiss*------*schnippel*--------------------------*knabber*-----*fetz*--- Ya estaria. Evidentemente, habreis de sustituir mi nombre (Pablo Gomez) por el vuestro y PERSONAL por el nombre de vuestro area personal. Cada vez que corramos ftoss, este se va a encargar de copiar al area personal los mensajes dirigidos a nosotros. Aqui merece la pena hacer un comentario. Y es que esto va a copiar tambien los mensajes a nuestro nombre recibidos en NETMAIL. A mi parecer, esto es un absurdo, ya que realmente el area NETMAIL ya es un area personal. Hasta donde se, no es posible modificar el comando para que no los copie. Por ello mas adelante tendremos que hacer un pequeño ajuste. Esto es un trozo (el importante ;-)) del script que corro al recibir correo. ,,, (o o) File: ~/bin/mimport ---*reiss*------*schnippel*------oOO--(_)--OOo-------*knabber*-----*fetz*--- #!/bin/sh # Para la gestion del area personal PERSAREA=PERSONAL # Importar correo ftoss # # Feeding area personal # Acabamos de repartir los mensajes, generando los duplicados necesarios # en PERSONAL.

" _________________________________________________________________ HAMS, PACKET RADIO AND LINUX by Phil Hughes, WA6SWR, phil@ssc.com Copyright (c) 1996 Published in Issue 10 of the Linux Gazette _________________________________________________________________ This year's ARRL/TAPR sponsored conference on Digital Communications was in Seattle on September 20-22. Being a ham, a packet fan and 18 miles away from the conference, I decided to attend. I also offered to bring some Linux Journal magazines to give away. By the end of the conference "some" had become about 100. The papers presented varied from very introductory material to a serious look at how to equalize group delay of IF filters. Many of the papers and one of the three workshops dealt with a system called Automatic Position Report System. For those not familiar with this, a GPS receiver is combined with a packet station to send out position reports. But, the purpose of this article is not to talk about the "ham content" of the conference (if you want more info on that, check out http://www.tapr.org/, but to talk about the L-word. In the first workshop (on APRS), Keith Sproul demonstrated both a Windows and a Mac version of the system, but regularly referenced the fact that a Linux version also existed. I was surprised (as there was no mention of a Sun version or any other Unix-like version), but I was now sure that Linux had infiltrated the ham packet radio community pretty seriously. The L-word then continued to come up in discussions with people. It varied from comments about installing Linux to how Linux became a significant part of a ham network. For example, in Barry McLarnon and Dennis Rosenauer's presentation on Wireless Networking Using the WA4DSY 56K RF Modem Technology, Barry said "Linux is the platform of choice". Later, when describing the Ottawa MAN (Metropolitan Area Network) he pointed out that their Internet server (hydra.carleton.ca) is a Linux box, and they, when talking about the packet gateway machine, said "It hasn't been converted to Linux yet." At the end of their presentation we had a chance to play with a wireless network set up in the room. The machine on one end of the 56K link was running Linux as was one downstream machine off the other end. All in all, the conference was good for Linux.

HORTON _________________________________________________________________ Date: Wed, 11 Sep 1996 16:46:31 GMT From: Victoria Welch vikki@seastar.org Organization: Welch Research laboratories Mark A. Horton (mah@netmha.com) passed away Friday September 7, 1996. Cause currently unknown, but poor health is suspected. he did have a lot of health problems, although he never let them keep him down long, in so many ways he was such an inspiration! Having been through the rest of the *nixes, and knowing the subject well, he was one of the greatest proponents of Linux. His enthusiasm and willingness to help anyone at any time were his greatest gifts to the Linux community. His kindness, willingness to help others in many ways including Linux and his generosity will be missed by those of us that knew him and an example for all of us to strive for. For me personally, he was my best friend and mentor. He taught myself and *MANY* others much about the nuts and bolts of Linux in a joyous way that was informative and instructive and often most pleasantly humorous. Most any interaction with Mark was a good time. Having spent a great many hours with him personally as well as on the phone, he made is very clear that he didn't want any morose happenings should anything ever happen to him, There will be a party by his friends to honor that request sometime in the near future. Will plan on celebrating his contributions and the many wonderful things that there are to be remembered about him. He was one of the true good guys and his joyous, creative, tenacious, encouraging spirit will be missed by those that knew him. To the many that knew Mark and to the many who didn't, hoist one to one of the greats! He will be missed.

That was until the discovery of a tiny utility called, mconv2. Mconv2 allows several programs to use a PS/2 type mouse at the same time. The mconv2 utility also supports the use of a PS/2 type mouse with applications that do not understand the PS/2 mouse protocol, but understand the microsoft serial mouse protocol (such as svgalib). This document only descrdibes the sharing of the PS/2 type mouse - not its use as a microsoft type mouse - for information on this, read the README file included with the mconv2 distribution. Installing and using mconv2 is VERY simple :- 1. Getting mconv2 Mconv2 can be downloaded from a variety of Linux archive sites. I got my copy from http://sunsite.unc.edu/pub/Linux/system/Misc/mconv2.tar.gz 2. Extracting Distribution Mconv2 is distributed as a compressed (gz) tar archive. Hence, it needs to be extraceted in a suitable directory before it can be installed. I used the /usr/src directory, but any directory will do. Copy the mconv2 distribution file (mconv2.tar.gz) to the selected working directory, eg. /usr/src (or the directory you care to extract it in) as follows :- cp mconv2.tar.gz /usr/src Go to the working directory and extract the mconv2 archive, as follows :- cd /usr/src tar -zxvf mconv2.tar.gz This will create a subdirectory called mconv2 containing, + the mconv2 source code - mconv2.c + a binary compiled mconv2 executable - mconv2 + supporting documentation files - mconv2.lsm and README 3. To compilie mconv2, or not Together with the source and supporting documentation, the mconv2 distribution also comes with a pre-built binary of the program. This can be used as-is or the program can be recompiled very easily, as follows :- gcc -O2 -o mconv2 mconv2.c 4. Installing the mconv2 binary Copy the pre-built, or newly made, mconv2 binary file (mconv2) to an appropriate directory for executing binarys from - I use /usr/local/bin. cp mconv2 /usr/local/bin 5. Builiding a fifo for the PS/2 mouse Create a fifo device (pseudo mouse driver) for the PS/2 mouse, as follows :- mkfifo -m 666 /dev/ps2mouse 6. Using mconv2 Before running any programs using the PS/2 mouse, mconv2 should be run first and other programs needing the mouse, should be configured to use the PS/2 pseudo device, /dev/ps2mouse. It is probably best, to start mconv2 from the /etc/rc.d.rc.local file with the following command :- echo -n "Runnig mconv2 .... " /usr/local/bin/mconv2 /dev/psaux -ps2 /dev/ps2mouse & echo "Done" NOTE :- this assumes your original mouse device was /dev/psaux 7. Configuring other programms to use mconv2 As mentioned in the point above, other programs requiring the PS/2 mouse must be configured to use the mconv2 pseudo mouse device - /dev/ps2mouse. Examples :- + To set up gpm, to use this pseudo device, invoke it as follows :- gpm -t ps2 -m /dev/ps2mouse & NOTE :- the -m option tells gpm what mouse device to use + To set up XFree86 to use the pseudo device, modify the Pointer section of the XF86Config file to set the mouse device to /dev/ps2mouse as follows :- Section "Pointer" Protocol "PS/2" Device "/dev/ps2mouse" Enjoy the PS/2 mouse sharing. My thanx to Frode Fjeld frodef@stud.cs.uit.no for developing the mconv2 distribution.

Rogers" RogersPL@datasync.com Good Morning, Late last week I became aware of the national NetDay96 project and volunteered at my daughter's school. During the weekend, I realized that this was an opportunity to involve the Linux community in a project that could not only benefit our local schools, but expose new classes of people to Linux. If this topic is suitable for SSC's ventures to publicize, please help spread the word. For NetDay96, maybe something in the _Linux Gazette_ could reach a few people in time to for them to make a contribution. If there is a NetDay97, perhaps an article in the _Linux Journal_ reporting on NetDay96 with suggestions on how to promote Linux during such an event would be appropriate. Attached is a posting that recently (1996/09/13) appeared on comp.os.linux.announce. A data point: The October 1996 LJ arrived in Ocean Springs, Mississippi on Friday. I strongly agree with "Linux people, now is the time to strike." and have recently become much more aggressive in sharing my experiences with Linux. Would you be interested in an article providing guidelines and suggestions on how to promote Linux? Thank you for your time and if this project is not suitable for SSC, perhaps other opportunities will allow us to work together in the future. Paul... ------------------------------------------------------------- Paul L. Rogers http://www.netday96.com RogersPL@datasync.com Are you prepared for NetDay96? (601) 875-3779 Linux: It works for me. ------------------------------------------------------------- _________________________________________________________________ NETDAY96 In the United States of America, preparations are under way for NetDay96. NetDay96 is a grass-roots effort to install the basic wiring required to make classrooms network ready. If Linux enthusiasts across the United States would participate in their local NetDay96 and be prepared to follow up with assistance in creating highly functional and reliable networks for our school systems, much favorable publicity could be generated for the Linux movement. This is an unique opportunity to expand the name recognition of Linux. The following steps describe how you can help: * Volunteer to help wire a school and wear a Linux T-Shirt to the event. * Be prepared to discuss the benefits (and limitations) of Linux. * Suggest that your Linux User's Group sponsors a school by funding a wiring kit. The cost of the wiring kit ranges from $339 to $376 depending on the vendor. * Contact a local Linux-based Internet Service Provider and request their support for NetDay96. For more information on NetDay96 or to volunteer, feel free to visit their web site at http://www.netday96.com. Some guidelines can be found at http://www.li.org/NetDay96-guidelines.html If you volunteer, please consider sharing your experiences and success stories with the community by sending them to li@li.org. We will post a report summarizing the success of this event. If you do not live in the United States, you may want to consider organizing a similar project for your community. _________________________________________________________________ LINUX INTERNATIONAL Linux International was established to promote the development and use of Linux.

There is also a detailed explanation that goes with it. The explanation is, in a sense, a general explanation on how to use the LinuxDoc package, since that's what we've decided to use for the GIMP Documentation Project. You can take a look at both the template and the explanation at: http://www.csn.net/~mjhammel/gimp/gdp/gdp.html (look under the plug-ins documentation section).

Hammel mjhammel@csn.net Last Updated: 09/04/96 This is a long page, but don't let that scare you. Creating your documents in SGML and using LinuxDoc tools to create your HTML, GNU Info, Man Page, or other formats is really pretty simple. This page just happens to be fairly thorough in explaining how to get it all done. There are 6 sections in the SGML template: * The Title Information Section * The Introduction Section * The Features Section * The Dialog Box Section * The Examples Section * The Notes Section Each section is described below. Along with these, there are a number of things you should be aware of when writing your document: * The Table of Contents * Section markers * Forcing new paragraphs * Comments * Lists * HTML or other format Specific tags * Notes about creating documents in the various formats As far as LinuxDoc itself is concerned, here are some things you might want to be aware of: * Where to get the LinuxDoc software: + The Home Page for LinuxDoc. + FTP Sites: o ftp://ftp.cc.gatech.edu/pub/people/gregh/linuxdoc-sgml/li nuxdoc-sgml-1.5.tar.gz o ftp://tsx-11.mit.edu/pub/linux/docs/linuxdoc-sgml-1.5.tar .gz o ftp://sunsite.unc.edu/pub/Linux/utils/text/linuxdoc-sgml- 1.5.tar.gz o ftp://ftp.cc.gatech.edu/pub/people/gregh/linuxdoc-sgml - Uptodate patches to version 1.5. * How to test your SGML * Updates I've made to the LinuxDoc package If you're interested in testing your SGML source, you should grab a copy of the LinuxDoc package at (put ftp site here). _________________________________________________________________ The Title Information Section This section has 6 tags in it: * article * title * author * inst * date * abstract All of these tags are mandatory and must be placed in this order. The article tag has no other text associated with it. It is put on a line by itself and is a marker to the SGML parser telling the parser what kind of document is to be created. Example:
The title tag is the name of the Plug-In. This must be one line long and on the same line as the title tag. Example: The Sparkle Plug-In The author tag identifies the author of the Plug-In. This should simply be the name of the developer. Along with this is a tag which identifies the email address of the author. The code for the email address looks similar to the following. Example: <author>Michael J. Hammel <htmlurl url="mailto:user@some.net" name="<user@some.net>"> Just substitute the appropriate email address. Note that the use of &lt; and &gt; are required. These get translated into the less-than and greater-than signs, respectively, in the output. The inst tag is just the current version number of the Plug-In source code. Example: <inst>Version 1.0 The date tag is the date that the source code was last updated. The format of the text that goes with this tag should look like the following: Example: <date>Last Updated: 09/01/96 The abstract tag marks the beginning of a paragraph of text that describes, in general, what the Plug-In does. This is free formatted text and must be followed by the <abstract> tag. Example: <abstract> Some text goes here. </abstract> _________________________________________________________________ The Introduction Section This section contains two subsections: * Where to get the software * How to build the software Both of these are mandatory subsections. Example section header: <sect>Introduction <P> The Where to get the software subsetion is a URL (ftp or http address) for the source code. If a binary version is available, the binaries location should be listed with the this subsection. Example: <sect1>Where to get the software <P> The software can be retrieved from <htmlurl url="ftp://ftp.some.net/dir/file.tar.gz" name="<ftp://ftp.some.net/dir/file.tar.gz>"> The How to build the software subsetion is simple an explanation on how to build the software. Example: <sect1>How to build the software <P> Building the source should be fairly straight forward. Just make sure the LIBS= line points to the location of libgimp.a. Also, a copy of gimp.h is included in the source. You should really delete this and make gimp.h a symbollic link to your copy of gimp.h (wherever you're keeping that) so that the latest version of gimp.h is used. _________________________________________________________________ The Features Section The Features Section is an itemized list of the features that the plug-in provides. This should include, at a minimum, a listing of all the buttons, sliders, or input fields in the dialog box. A very brief description of the features can be included. This is desirable if the feature listed is not one that is readily apparent from the dialog box. Example: <sect>Features <P> <itemize> <item>Feature one <item>Feature two <item>Feature three </itemize> See the section titled Lists for a description on how to create lists using the template. _________________________________________________________________ The Dialog Box Section The Dialog Box Section describes the features found in the Plug-In's pop-up dialog box and explains how they effect images. This section is made up of an screen capture image (for the HTML formatted output files) of the dialog box, an numbered list of features, and a feature-by-feature breakdown. To start this section, use the followgin: <sect>The ... Dialog Box <label id="dialog"> <P> Replace the three dots with the name of the Plug-In. After the section header, a list of features should be provided. The list will look something like this following: <itemize> <item><em><ref id="feature1" name="Feature One"></em> <item><em><ref id="feature2" name="Feature Two"></em> <item><em><ref id="feature3" name="Feature Three"></em> </itemize> The name tag is what will show up in the list. The id tag is a cross reference that you will use later. The <em> tags just cause the stuff inbetween to be put in italics. After you create the list, you should force a break after the image. This will only affect HTML output for now. This is the line you should add to force the break: <![%fmthtml; [ <? <BR clear="both"> > ]]> Now you should add the subsections that fully explain each feature. For the first item in the list above, you would add the following: <sect1>Feature One <label id="feature1"> <P> This is the text explaining the first feature. The sect1 tag signifies you are starting a subsection. The label with its id gives this section a name that can be used as a cross-reference. We used this in the list of features earlier. You would have a subsection just like this for each feature in your dialog box. _________________________________________________________________ The Examples Section (and how to use format-specific tags) This section is more complex than the others. Examples of how the GIMP Plug-Ins work aren't of much use without some images to go with them. Unfortunately, not all output formats support images (remember: we're using SGML so we can create HTML, info, man pages, and whatever other formats are supported by the LinuxDoc package). We need to force this section to be processed differently depending on which formatter we're running the SGML source through. The way we do this is to use format-specific tags and the SGML equivalent of an escape sequence. You're already seen one of these in the section where we forced an HTML break tag. The generic format of this SGML tag is: <![%fmttag; [ <? ... > ]]> Where fmttag is one of * fmthtml * fmttxt * fmttex * fmtrtf * and so forth and the 3 dots are the format-specific text you want to be passed directly to the output file. If the sgml parser sees the fmttag tag and it matches the output format you've requested then the format-specific text is written to the output file. If it doesn't match the format requested, the text is ignored. Thats the technical explanation. Whats worse is it doesn't appear to work (or I'm doing it wrong - one of the two). Until I figure this problem out you have one of two choices: * Put in a URL pointing to examples on some other page * Use the Sparkle SGML source as an example. The former of these can be done with the following line: <htmlurl url="http://www.some.net/dir/file.html" name="<http://http.some.net/dir/file.html>"> Just substitute the appropriate URL. The latter of the two options can be downloaded from http://www.csn.net/~mjhammel/gimp/gdp/plug-ins/sparkle.sgml. You may need to hold down the Shift key to force this file to be downloaded and not displayed. _________________________________________________________________ The Notes Section The Notes Section is the place to stuff everything that doesn't fit neatly into the other sections, such as known bugs, limitations, or future enhancements that are planned. Example: <sect>Notes <P> _________________________________________________________________ The Table of Contents This is a single line that goes immediately after the Title Information Section and immediately before the Introduction Section. It should look exactly like this: <toc> _________________________________________________________________ Section Markers There are several layers of sections available, but we only require the top two: <sect> <sect1> The sect tag forces a new page in the output files. The sect1 just gets another type of formatting on that same page. You can add sect2 and sect3 levels if you want, but I'm not sure what they do to the output. Note that you must put the following immediately after the section tags: <p> This tells the SGML parser to end the section header and begin the part of the document that belongs in that section. _________________________________________________________________ Forcing new paragraphs This is simple, just add the following: <p> Note that its also possible to use blank lines to force new paragraphs, but whether the SGML parser uses the blank line as a paragraph or not depends on where its used. Its easier to just use the above tag to be sure. _________________________________________________________________ Comments If you want to put comments in your SGML, you would do it like so: <-- This is an SGML Comment line --> Note that this is very similar to the HTML comment. _________________________________________________________________ Lists To create a bulleted list, do the following: <itemize> <item>Item one <item>Item two <item>Item three </itemize> To create a numbered list, do the following: <enum> <item>Item one <item>Item two <item>Item three </enum> Pretty straight forward, really. _________________________________________________________________ How to test your SGML You can verify your SGML documentation will work with the various format converters by running it through each one. For example, to check if you can get the HTML output with an SGML file called plugin.sgml, try: sgml2html plugin To get text output, try: sgml2txt plugin To get man page output in groff format, try: sgml2txt -man plugin You should read the man pages for each of the sgml2<whatever> commands to learn the command line options. They are really pretty easy to use. _________________________________________________________________ Updates I've made to the LinuxDoc package I've made two distinct changes to the LinuxDoc package. The first is to the linuxdoc.dtd file, found under the lib/dtd directory after you unpack LinuxDoc. The following was added right before the last line: <!-- added fmt* which were somehow missing --> <!-- default is ignore, override on commandline in sgml2* --> <!entity % fmttex "ignore"> <!entity % fmthtml "ignore"> <!entity % fmttxt "ignore"> <!entity % fmtinfo "ignore"> <!entity % fmtrtf "ignore"> <!entity % fmtlyx "ignore"> These allow for format-specific tags in the SGML source so you can, for example, add a graphic in your HTML output but just include the description of the image in your text output. The other change was to the html2html.l flex file under html-fix. The changes aren't complex, but theres a number of them to allow for command line options to set the background, text, and link colors. If you want this I can send it to you, but its not really necessary to test your SGML before submitting it to me. _________________________________________________________________ Notes about creating documents in the various formats First of all, there are a set of scripts in LinuxDoc for creating documents in the various formats: * sgml2html * sgml2txt * sgml2info * sgml2rtf * sgml2lyx * sgml2latex Note: In order to do format specific tagging, you'll need to update your linuxdoc.dtd file. See the section on LinuxDoc Updates (found on the website listed in the introductory section of this article) for the details. The first of these, sgml2html, was used to create the new Sparkle documentation, as well as the HTML version of the SGML template. It works quite well using "free-formatted" input files. By free-formatted I mean that the actual text (not the formatting tags) can be one word per line or any number of words per line and the output will come out nicely formatted using as many words as will fit in your web browser. The text formatter, sgml2txt, also works quite well. The output has various formatting characters that work well with the "less" and, possibly, "more" pagers. The GNU Info formatter, sgml2info, is not happy with such free formatting of the text, however. I have not tried the other formatters yet. I don't know what RTF is and I've not used the Lyx or Latex tools so I'm not sure how to test the output from these formatters. Michael J.

" _________________________________________________________________ SETTING UP DYNAMIC IP WEB SERVER VIA PPP CONNECTION By Henry H. Lu, honglu@rt66.com, http://www.tc.umn.edu/nlhome/m508/luxxx012/ Copyright (c) 1996 Published in Issue 10 of the Linux Gazette Have you been thinking of seting up a reachable web server at your home PC in addition to your permenent page at ISP? There are obvious reasons to do this: You can show off your home linux box to the world; you do not need to use other messy method (email) to know your current IP in order to login remotely; finally, it is fun! First, You need to have ppp connection and httpd working and a PERMANENT web page before trying the following dynamic IP solution. DESCRIPTION OF FILES: web_up: shell script I run to update webpage at permenet site with new IP whenever connection is up. web_down: shell script I run before shutting down the link, to inform others of the shutdown update_uppage: perl scripts to creat up.html page with updated IP address on the fly, called by web_up. up.html_source: fixed part of up.html down.html: web page used when link is down. /etc/add, /etc/last_add: files where I put IP address. ip-down, ip-up: files executed when ppp link is disconnected or connected. they are used to update the /etc/add files here. NOW LETS LOOK AT SCRIPTS WEB_UP: ------------------------------------------------------------------ #!/bin/sh #check new IP new_ip() { if [ -f /etc/add ]; then if [ -f /etc/last_add ]; then if /usr/bin/diff /etc/add /etc/last_add >/dev/null ; then exit 1 else return 0 fi else return 0 fi else exit 1 fi } #check whether maroon is connected try_connect() { if ping -c4 -l3 128.101.118.21 2>&1 | grep "0 packets" > /dev/null then return 1 else return 0 fi } if try_connect then touch /var/run/maroon_connected else rm -f /var/run/maroon_connected fi # ftp to update page if [ -f /var/run/maroon_connected ] && new_ip then # update_uppage is perl scripts, exit status is opposite of shell if ( ! /home/honglu/public_html/update_uppage ) then cd /home/honglu/public_html if echo "put up.html /nlhome/m508/luxxx012/dynamic.html" \ | /usr/bin/ftp maroon then rm -f /etc/last_add cp /etc/add /etc/last_add exit 0 else exit 1 fi fi else exit 1 fi ----------------------------------------------------------------- Now let's look at web_up in detail. Function new_ip() is used to check whether we have new IP and whether the new IP is different from the last one. /etc/ppp/ip-up and /etc/ppp/ip-down update IP adress in files /etc/add and /etc/last_add so that we can compare files "add" with "last_add" to tell whether we need to update page. Function try_connect() is used to test whether the perment web site is reachable. Next is fun part, I used automatic feature of ftp to update webpage. In order to make it work, you have to set file ~/.netrc correctly, type "man ftp" for more information. update_uppage is straitforward perl scripts to parse and creat up.html by using new IP from /etc/add file. Final part is to update /etc/add /etc/last_add to reflect correct status IP address. You can put "web_up" in your crontab entry ( or ip-up, or keapalive.sh) to let it execute automatically whenever your PC is connected. WEB_DOWN IS A SIMILAR PAGE, MAIN DIFFERENCE IS IN FTP PART: ----------------------------------------------------- ...... ...... # ftp to send down.html page if [ -f /var/run/maroon_connected ] then cd /home/honglu/public_html if echo "put down.html /nlhome/m508/luxxx012/dynamic.html" \ | /usr/bin/ftp maroon then rm -f /etc/last_add else exit 1 fi else exit 1 fi ---------------------------------------------------- Instead of ftp up.html as web_up did, web_down put down.html to permenent web site to inform the delink of page. web_down should be run before you shut down the machine. I created a scripts called "shut" to shutdown machine: ----------------------------------------- #!/bin/sh if web_down then shutdown -h now else echo "can not web_down" exit 1 fi ----------------------------------------- For more detail check out my home page for source code: http://www.tc.umn.edu/nlhome/m508/luxxx012/ Henry H Lu _________________________________________________________________ [ TABLE OF CONTENTS ] [ FRONT PAGE ] Back Next _________________________________________________________________ XaoS: A New Fractal Program for Linux _________________________________________________________________ by Larry Ayers Copyright (c) 1996 Published in Issue 10 of the Linux Gazette _________________________________________________________________ Transforming certain recursive complex-number formulae into images of unlimited depth and complexity was only made possible by the development of the modern computer. Benoit Mandelbrot, a Belgian researcher working for IBM, first discovered the Mandelbrot set in 1981. By the mid-eighties personal computers had evolved to the point that anyone could experiment with various fractals, and programmers soon discovered that the 8-bit 256-color vga palette could be mapped to various parameters, which allowed the creation of stunning animated images. The most comprehensive and feature-filled of all fractal-generation programs is Fractint, a freeware program originally written for DOS. Fractint is maintained by a far-flung group of developers, rather like Linux. It was ported to unix by Ken Shirriff and a Linux version is commonly included in many Linux distributions. Not all features of the DOS version work in Linux, and if you just want to see what fractals are all about Fractint is probably overkill. It has such a multitude of options and features that it can be somewhat overwhelming to a new user. Recently Jan Hubicka (developer of the Koules X-window game) and Thomas Marsh have released a small fractal program for Linux called XaoS. This is an efficient program, with the option to compile both X-Windows and SVGA-console versions. XaoS can't render the dozens of fractal types which Fractint can, but it does the basic Mandelbrot and Julia sets quickly, with several keyboard options. It's developers refer to XaoS as "an interactive real-time fractal zoomer," and zooming in on an area of the Mandelbrot set is where XaoS excels. Pressing a mouse button anywhere in the image will begin a zoom with the location of the cursor as target. The "autopilot" mode is quite impressive; pressing "a" will start an automatic zoom which homes in on detailed areas. In the X-windows version the default window-size is 320x200; if you don't mind the cpu-usage a small XaoS window zooming away on the desktop can be pleasant to contemplate as you pause in your work. For those working in virtual consoles an SVGAlib version can be run in a variety of resolutions. Generating fractal images is inherently CPU-intensive. The faster your processor the better, especially when zooming in real time. XaoS does pretty well on my 80-mhz 486, but this may be near the lower limit. Here's a screenshot of XaoS: XaoS Window at 320x200 XaoS only works on 8-bit displays at present, as is also true of Fractint. Images can be saved to GIF files by means of a keystroke. _________________________________________________________________ INSTALLATION Xaos uses a configure script for compilation, and it should compile easily on most systems. The executable is only about fifty kilobytes and is completely self-contained, i.e. no subsidiary files are required. _________________________________________________________________ AVAILABILITY The Xaos home-page is a good source for the latest version; the source has also been uploaded to Sunsite and its mirrors. Larry Ayers _________________________________________________________________ [ TABLE OF CONTENTS ] [ FRONT PAGE ] Back Next _________________________________________________________________ XMOSAIC DEVELOPMENT ON A ROLL by Larry Ayers Copyright (c) 1996 Published in Issue 10 of the Linux Gazette _________________________________________________________________ Netscape binaries are more-or-less freely available for Linux, and the program works well, most of the time. As a Linux user I've become accustomed to a large potential for customization in software, right down to the source-code level. Netscape is available only as a large, opaque executable and the source is proprietary. I don't necessarily want a web-browser to fetch email and newspostings for me; I use other programs for those purposes but with Netscape those functions are unwanted baggage, loaded into memory every time the browser start up. The recent beta versions of Xmosaic (the latest is 2.7b5) have been quicker-loading alternatives. Background colors and images are supported, but it just isn't as quick to load images and pages as Netscape. Scott Powers, head of the Xmosaic development team at the University of Illinois, has for the past couple of months been leading a new Xmosaic project. The Xmosaic developers felt that the code upon which the version 2.7 and earlier browsers had been based needed a complete rewrite. Version 2.8 is now in public alpha testing. The project has been dubbed "Hyperion", as a sign that something totally new is in the works. A mailing list for Hyperion has arisen lately. Perusing the messages from the developers one can feel the excitement in the air. These people are really motivated, and working extremely long hours as well. Most days a "snapshot" of that day's code level is available from their ftp site. The first alpha releases were pretty rudimentary; there was no image support and many HTML files couldn't be loaded. I think that the source code was released at such an early level so that the developers could be sure that the core parsing routines, etc., could be successfully compiled on all targeted platforms. On September 10 the alpha version 2 was completed and released. Image support is now functional, though at this stage you must use specific versions of the JPEG and Xpm libraries. There's still a long way to go before Xmosaic 2.8 is actually very usable, but that's what the alpha tester's reports are helping to expedite. _________________________________________________________________ WHAT CAN WE EXPECT? Scott Powers and the rest of the Hyperion team have an impressive list of planned features. One of the most exciting is a modularization of the source code. This means that if you wanted a speedy, basic browser the compile-time option would be available to not include, say, Java and sound support. A user could conceivably compile several versions, each with different capabilities. Developers of web-browsers are faced with some difficult decisions. What standards to follow? How many of the "Netscape-isms" are now prevalent enough to be considered desirable? As an example, tables are now standard and to be expected in any new browser, as are forms. Frames are another matter; they are common on the web but many find them of limited value and they have yet to gain widespread acceptance. Xmosaic 2.8 will be HTML-3 compliant, and various sorts of multimedia support are being discussed. The alpha-testers have been making numerous suggestions, and their ideas are being taken seriously by the Xmosaic team. _________________________________________________________________ LOCATIONS AND SOURCES If you'd like to check in from time to time and see what progress has been made, Xmosaic 2.8 is the home-page. The current alpha (and before too long, beta) version source code can be downloaded from the page. The ftp site might be faster, but at this early stage the source code is only about three hundred kilobytes. Information concerning the mailing list is also on the home page. I encourage anyone who has a little time and the inclination to participate in the alpha testing. Every bug report contributes to a higher quality final release, and I'd hate to see Xmosaic 2.8 work really well only on Sparc or HPUX machines because not enough Linux users contributed reports!

John Fisk is right--the Gazette is a lot of work, and worth every bit of it. Thanks to all our authors, not just the ones above, but also those who wrote giving us their tips and tricks and making suggestions. Thanks also to our new mirror sites. I get more mail about mirrors than just about anything, except maybe readers wanting the Gazette to be available as one big file. We are providing that this month along with the separate page format. (See TWDT in the Table of Contents.) Doing the Gazette in multi-file format is just the easiest way for me to build the magazine. I've tried to be responsive to all mail and reasonable requests. If I missed you, send your mail again, and I'll get back to you. The most important thing I'm working on outside of work these days is definitely "not Linux". I'm making a baby quilt for a friend of mine in Houston. The baby is 2 months old now, and if I don't get it finished soon, it will be too small for her to use. The geometry, as well the art, of quilting has always fascinated me--must have to do with being a math person. If you would like some personal information about me, clicking on my name below will take you to my home page. It's not very jazzy at the moment, but I'm looking for the time to fix it up. _________________________________________________________________ Marjorie L.
