Linux Gazette, a member of the Linux Documentation Project, is an on-line WWW publication that is dedicated to two simple ideas:
TWDT 1 (text)
TWDT 2 (HTML)
are files containing the entire issue: one in text format, one in HTML.
They are provided
strictly as a way to save the contents as one file for later printing in
the format of your choice;

Subject: Quilting and geometry
From: Chris Hennessy,
chenness@enterprise.powerup.com.au
I liked your comment about quilting being an interest. We tend to forget that people have interests outside of computers in general (and linux in particular).
Just like to say thanks for what is obviously an enormous effort you are putting into the gazette. I'm new(ish) to linux and I find it a great resource, not to say entertaining.
Has anyone suggested an article on the use of Xresources? As I said I'm fairly new and find this a bit confusing... maybe someone would be interested in an example or three?
Oh and with the quilting and geometry ... better make sure its not the 80x25+1-1 variety.
(Thanks, LG is a lot of work, as well as a lot of fun. And yes, I do have a life outside of Linux. Anyone interested in writing about Xresources? Thanks for writing. It's always nice to know we are attracting new readers. --Editor)

Great Resource,
I really like the resource Linux offers new users. I have already applied a few tricks to my PC. I wish some one would explain how to use the GNU C/C++ compiler with Linux. It is a tool resting in my hard drive. With commercial compilers, there is a programming environment that links libraries automatically. Are there any tricks to command line C/C++ programming with Linux?? Stay online!

Subject: Linux InfraRed Support
From: Hong Kim,
kimh@domp04.adm.intelsat.int
Hi,
I have been so far unsuccessful in finding information for InfraRed support on Linux.
I am particularly interested in hooking up Caldera Linux on a Thinkpad 560 using Extended Systems JetEye Net Plus. Caldera on Thinkpad I can handle but the JetEye allows connection to ethernet or token ring networks via IR.
My searches of Linux Resources page come up negative. I have posted to USENET and also emailed any web master that has any mention of ThinkPad or IR on their pages. Still no answer.
Can you help me to find information. If I am successful, I would be willing to write an article about it.
Hong
(I have sent your question on to Linux Journal's Tech Support Column. Answers from this source can be slow as author contacts companys involved. Sounds like you have covered all the bases in your search -- can anyone out there help him? If you write the article, I'll be happy to post it in the LG so next person who needs this information will have a quicker answer. --Editor)

From:
Tauche%fbm%mfh@mfhdvzis.mfh-iserlohn.de
Hi there,
First I have to apologize for writing to this address with my problem, but I don't no where to search for an answer and university's network is so damned slow that surfing through the net searching for an answer makes no fun. Another reason is that I've got no access to Usenet... means can't post in comp.os.linux.networking... 8-((
I tried to find a news server near to Germany which allows posting without using that damned -> identd <- but found none, may be you know where to find a list with (free) news servers ?
Here's the problem:
I want to setup Linux in our University's LAN but ran into problems, because
the LAN is VINES-IP based so that normal TCP/IP packet drivers won't work.
The admin says I do need a driver which can tunnel the normal Linux TCP/IP
packets into those VINES-IP packets, so that they can be send over the LAN to
that box which has Internet connection....
Maybe you know if such thing is available and/or where I can get it. Or maybe you can give some Email-addresses for asking people which real knowledge 'bout Linux (maybe even that of Linus T. himself) and it's drivers.
Hope you can help me 8-))
Thanks in advantage
Stefan 8-))
(I've sent your problem on to Linux Journal's Technical Support column and will post it in Linux Gazette's Mailbag next month. Neither one will give you a fast answer.I did a search of LG, LJ and SSC's Linux Resources using VINES as the keyword. I found only one entry from an author's biography. It's old -- March 1995 -- and the guy was in the marine corp then so may or may not be a good address. Anyway here's what it said:
"Jon Frievald ... manages Wide Area Network running Banyan VINES. ... e-mail to jaf@jaflrn.liii.com"Anyway you might give him a try for help ideas.
For faster access to LG have you tried any of LG's mirror sites in Germany:
- http://www.cs.uni-dusseldorf.de/~stein/lg
- http://vina12.va.htw-dresden.de/lg
- http://www.fokus.gmd.de/linux/lg

this a pre-alpha version!!!
i can't do so unfixed products!!!
i'm sorry, but you forgotten how make a http-ready distrbutions... :)
Sergey Panskih
P.S. email me if i'm not true.
(I'm having a little trouble with your English and don't quite understand what "all graphics was loosed" means. You shouldn't have to copy anything anywhere: what are you copying to /images?There is one problem I had that may apply to you. Are you throwing away previous issues and only getting the current one? If so, I apologize most humbly. I was not aware until this month that people were doing this and when I made the tar file I included only new files and those that had been changed since the last month. To correct this problem I put a new tar file on the ftp site called standard_gifs.html. It's not that I've forgotten how to make http-ready distributions, it's that I'm just learning all the complexities. In the future I will make the tar file to include all files needed for the current single issue, whether they were changed or not.
I am very sorry to have caused you such problems and distress. --Editor)

Subject: spiral trashes letters
From: jep@jephill.com
It's clever and pretty, but the spiral notebook graphic still trashes the left edge of letters printed in the issue 12 Mailbag.
Problem occurs using OS/2's Web Explorer version 1.2 (comes with OS/2 Warp 4.0). Problem does NOT occur using Netscape 2.02 for OS/2 beta 2 (the latest beta for OS/2).
Problem occurs even while accessing www.ssc.com/lg
Jep Hill
(Problem will always occur with versions of either Microsoft Explorer or Netscape before 2.0. It is caused by a bug in TABLES that was fixed in the 2.0 versions. I don't have access to OS/2's Web Explorer, so I can only guess that it's the same problem. I'd recommend always using the latest version of your browser. --Editor)

Subject: Background
From: rayvd@shocking.com
I run at a resolution of 1152x846 (a bit odd I suppose) and although the Gazette pages look very nice indeed, it is a bit hard to read when I have my Netscape window maximized. The bindings part of the background seems to be optimized for a width of 1024 and thus tiles over again on the right side of the page. This makes reading a bit difficult as some of the text now overlaps the bindings on the far right.
I'm not sure if that's a great description of the problem, but I can easily make you a screenshot if you want to see what I mean.
Anyhow, this is only a minor annoyance--certainly one I'm willing to live with in order to read your great 'zine. :)

(Screen shot wont be necessary. When the web master first put the spiral out there, the same thing happened to me -- I use a large window too, but not as large as yours. He was able to expand it to fix it at that time. I notified him of your problem, but not sure if he can expand it even more or not. We'll see. Glad it's a problem you can live with. :-) --Editor)

Subject: Problem with Printing.
From: fm@M1.whitespace.de
Hi,
This is just to let you people know, that there might be a slight problem. I want to point out and make it perfectly clear that this is NOT a complaint. I feel perfectly satisfied with the Linux Gazette as it is.
However sometimes I prefer to have a printed copy to take with me. Therefore I used to print the LG. from Netscape. I'm using the new 3.1 version now. With the last two issues I have difficulties doing so. All the pages with this new nice look don't print too well. The graphics show up at all the wrong places and only one page is printed on the paper. The rest is swallowed. Did you ever try to print it?
I had to use an ancient copy of Mosaic, that doesn't know anything about tables, to print these pages. They don't look too good this way too, and never did. I know this old Mosaic is buggy. At least it doesn't swallow half of the stuff. This could as well be a bug in Netscape. I know next to nothing about html.
Anyway, have fun.
Regards Friedhelm
(No, I don't try to print it, but will look into it. Are you printing out "TWDT" from the TOC or trying to do it page by page? It is out there in multi-file format and so if you print from say the Front Page, the front page is all you'll get. "TWDT" is one single file containing the whole issue, and the spiral and table stuff are removed so it should print out for you okay. Let me know if this is already what you are printing, so I'll know where to look for the problem. --Editor)

Well, Hi there!
Amazing. I've just read the Linux Gazette from the first issue to this one, the 12th (actually I read just the first 7 issues through, because the others were not downloaded correctly).
It's 4 in the morning and I'm enthusiastic. I knew Linux was good, I'm using it for a year (this is because of the lack of my english grammar, I mean the previous sentence, well...), so I knew it was good, but I didn't expect to see something so nice like this Gazette.
It's good to see that there are a WHOLE LOT of people with huge will to share.

Subject: One-shot downloads
From: David M. Razler, david.razler@postoffice.worldnet.att.net
Folks:
While I realize that the economies of the LINUX biz require that there be some method of making money even on the distribution of free and "free" software, I have a request for them of us who 1) are currently scraping for the cash for our Internet accounts and 2) would like to try LINUX.
How about a one-shot download? I mean, oh, everything needed to establish a LINUX system in one ZIP'ed (or tar/gz'd, though zip is a more compatible format) file, one for each distribution?
I'm currently looking to establish LINUX on my "spare" PC, a 386DX-16 w/4 meg and a scavenged 2500MB IDE drive, etc. It will be relatively slow, limited, lacks a CD-rom drive, but it's free, since the machine is currently serving as a paperweight.
I could go out and buy a used CD-rom for the beast, or run a bastard connection from my primary, indispensable work machine and buy the CDs. But I am currently disabled and spending for these things has to be weighed against other expenses (admittedly, I am certainly lucky and not destitute, it would just be better)
I could get a web robot and download umpteen little files, puzzle them out and put them together, though the load on your server would be higher.
Or, under my proposed system, I could download Distribution Code, Documents, and Major accessories in one group, then go back for the individual bits and pieces I need to build my system.
Again, I realize that running your site costs money, and that people make money, admirably little money, distributing LINUX on CDs, with the big bucks (grin) of LINUX coming in non-free software, support and book sales.
But if the system is to spread, providing a series of one-shot downloads, possibly available only to individuals (I believe one could copyright the *package* and require someone downloading to agree to use it only on a single non-commercial system and not to redistribute, but I am not an intellectual properties lawyer), to make life easier for them of us who need to learn a UNIX-style system and build one on the cheap.

Console Trick Follow-up
Just finished reading issue #12, nice work.
A followup to the "Console Tricks" 2-cent tip:
What I like to do is have a line in /etc/syslog.conf that says:
*.* /dev/tty10that sends all messages to VC 10, so I can know what's going on whether in X or text mode. Very useful IMHO.

GIF Animations
I too thought WhirlGIF (Graphics Muse, issue 12) was the greatest thing since sliced bread (well, aside from PNG) when I first discovered it, but for creating animations, it's considerably inferior to Andy Wardley's MultiGIF. The latter can specify tiny sprite images as parts of the animation, not just full images. For my PNG-balls animation (see http://quest.jpl.nasa.gov/PNG/), this resulted in well over a factor-of-two reduction in size (577k to 233k). For another animation with a small, horizontally oscillating (Cylon eyes) sprite, the savings was more than a factor of 20(!).
MultiGIF is available as source code, of course. (And I had nothing to do with it, but I do find it darned handy.)

Re: How to close and reopen a new /var/adm/messages file
Regarding the posting in issue #12 of your gazette, how to backup the current messages file & recreate, here is an alternative method...
Place the lines at the end of this messages in a shell script (/root/cron/swaplogs in this example). Don't forget to make it +x! Execute it with 'sh scriptname', or by adding the following lines to your (root's) crontab:
# Swap logfiles every day at 1 am, local time 0 01 * * * /root/cron/swaplogsThe advantage to this method over renaming the logfile and creating a new one is that in this method, syslogd is not required to be restarted.
#!/bin/sh cp /var/adm/messages /var/adm/messages.`date +%d-%m-%y_%T` cat /dev/null >/var/adm/messages cp /var/adm/syslog /var/adm/syslog.`date +%d-%m-%y_%T` cat /dev/null >/var/adm/syslog cp /var/adm/debug /var/adm/debug.`date +%d-%m-%y_%T` cat /dev/null >/var/adm/debug

Info-ZIP encryption code
This is a relatively minor point, but Info-ZIP's Zip/UnZip encryption code is *not* DES as reported in Robert Savage's article (LG issue 12). It's actually considerably weaker, so much so that Paul Kocher has pub- lished a known-plaintext attack (the existence of which is undoubtedly the reason PKWARE was granted an export license for the code). While the encryption is good enough to keep your mom and probably your boss from reading your files, those who desire *real* security should look to PGP (which is also based on Info-ZIP code, but only for compression).
And while I'm at it, Linux users will be happy to learn that the upcoming releases of UnZip 5.3 and Zip 2.2 will be noticeably faster than the cur- rent publicly released code. In Zip's case this is due to a work-around for a gcc bug that prevented a key assembler routine from being used--Zip is now 30-40% faster on large files. In UnZip's case the improvement is due to a couple of things, one of which is simply better-optimized CRC code. UnZip 5.3 is about 10-20% faster than 5.2, I believe. The new ver- sions should be released in early January, if all goes well. And then... we start working on multi-part archives. :-)

Kernel Compile Woes
Greetings. Having been through hell after a recompile of my kernel, I thought I'd pass this on.
It all started with me compiling a kernel for JAVA binary support..who tell me do that. Somehow I think I got experimental code in..even worse :> Anyway, it resulted in a crash, and I couldn't recompile since then.
Well, after several cries for help, and trying all sorts of stuff, I upgraded binutils to 2.7.0.3, and told the kernel to build elf support and in elf format, and hey presto. I'd been wrestling with the problem for well over a week, and every time, I'd get an error. Unfortunately, I had to take out sound support, so I'm going to see if it'll add back in.
I have to say thank you to the folks on the linux-kernel mailing list at vger.rutgers.edu. I posted there once, and had back at least 5 replies in an hour. (One came back in 10 minutes).
As for the LG, it looks very nice seen thru Lynx 2-6 (no graphics to get messed up :>) I love the Weekend Mechanic, and the 2 cent tips mainly. Perhaps one day I'll contribute something,.

I don't use vi, so I left out that functionality.
The functional changes I made are all in the arguments to the echo command. The changes are to use \\033 rather than what was shown in the original tip as ^[, to use \\007 rather than ^G, and to terminate the string with \\c rather than use the option -n.
On AIX 4.1, the command "echo -n hi" echoes "-n hi"; in other words, -n is not a portable command-line option to the echo command. I tested the above script on AIX 3.2, AIX 4.1, HPUX 9.0, HPUX 10.0, Solaris 2.4 and Solaris 2.5. I'm still trying to get Linux and my Wintel box mutually configured, so I haven't tested it on Linux.
I have noticed a problem with this script. I use the rlogin command to log in to a remote box. When I exit from the remote box, the caption is not updated, and still shows the hostname and path that was valid just before I exited. I tried adding
exits () { "exit" $*; eval stripe; }
alias exit=exits
and
rlogins () { "rlogin" $*; eval stripe; }
alias rlogin=rlogins
Neither addition updated the caption to the host/path
returned to. Any suggestions?

Letter 2 to the LJ Editor re Titlebar
Some further clarification is needed with respect to the X Term Titlebar Function tip in the Linux Gazette Two Cent Tips column of the January 1997 issue. With regard to the -print option to find, Michael Hammel says, "Linux does require this." This is yet another example of "Your mileage may vary." Some versions of Linux do not require the -print option. And, although Solaris may not, SunOS 4.1.3_U1 and 4.1.4 do require the -print option. Also, if running csh or tcsh, remember to escape wildcards in the file specification ( e.g. find ./ -name \*txt\* ) so that the shell doesn't attempt to expand them.
Second, for those tcsh fans out there, here is an xterm title bar function for tcsh.
NOTE: This works on Slackware 3.0 with tcsh version 6.04.00, under the tab, fv, and OpenLook window managers. Your mileage may vary.
if ( $TERM == xterm ) then
set prompt="%h> "
alias cwdcmd 'echo -n "^[]2;`whoami` on ${HOST} - $cwd^G^[]1;${HOST}^G"'
alias vi 'echo -n "^[]2;${HOST} - editing file-> \!*^G" ; vim \!* ;
cwdcmd'
alias telnet '/bin/telnet \!* ; cwdcmd'
alias rlogin '/usr/bin/rlogin \!* ; cwdcmd'
cwdcmd
else
set prompt="[%m]%~% "
endif

This here is the way I do it, but don't use it if your area has some regulations about redialing the same phone numbers over and over:
