Subject: Linux Gazette comment
Hi John,
Thanks for taking the time for putting together the Gazette. I hope you have some time left over for doing work for your employer !!! I trust/hope that Phil Hughes will be able to keep the Gazette going ... I've certainly enjoyed the Gazette over the last year. One comment though. In the most recent issue (#8) the format has changed so that the Gazette is no longer (easily) printable, but is split among many pages. I know this is supposed to be an e-zine, but I liked the old format better :-(. I'd hazard to guess that I'm not alone in this, but probably in the minority..... Any chance of putting an organized single postscript file on the ftp site? That way those of us loosers who like to read from paper at our leisure (and don't have laptops, sigh..) can still easily print out a copy of the Gazette. This may understandably not fly with Phil, but I thought I'd suggest it and see what happens anyway!
Thanks again for all your work!

(Yes, you are in the minority, and I must say it is much easier for me if the Gazette is in a multi-part format. As a result, it's very likely to stay in multi-part format. However, you should note that it can be downloaded as one file from the SSC ftp site -- ftp.ssc.com/lg/. So you could download it, convert it to postscript, print it and read at your leisure. We're not going to do all the work for you -- that would take all the fun out of it. :-) --Editor)

This month I've found some really nice utilities and programs in the incoming directories of the Linux archive sites. If any of you LG readers find (or have written) a program you're excited about, and don't have the time or inclination to write a piece for the Gazette, drop me a line telling me what you like about it and its location. I'll include a piece on it in next month's issue.

Subject: MindQ Publishing Inc.'s Intro to Programming Java Applets
Dear Editor:
"I'm a programmer and I want to spend a few hours getting acquainted with Java applet programming. Is there a faster way to learn than books?" "I'm not a programmer, but I want to learn about Java without wading through Dweeb books. Is there a way?" "My programmers are learning Java and I want to keep up without being overwhelmed. How do I do that?"
These are comments we overheard at the Web Interactive Show in New York this month. The point? It's not just hard-core techies who want to learn about Java--or have time to read the books. So where do the rest of us go?
MindQ Publishing Inc.'s "Intro. to Programming Java Applets" is a multimedia CD-ROM tutorial designed to teach all of the above--using animation, audio, video and hypertext. Experienced programmers can use the hyperlinked table of contents to find exactly what they need. Newbies can jump on any one of five tours. People inbetween can use a combo. All of them can use the Java Developers Kit, or the Launch button to go right to other Java-related programs or websites (when the Launch capability is activated). The program retails for $49.95, but I can provide you with an eval copy. Please email me: MikKass@aol.com, or call me (203)323-4166. Thanks. I look forward to hearing from you.
Cordially,

Just scanning through back issues and came across the tip to keep the hostname

into despite logging in from one to another and logging out, I put

Hi,
As a new linuxer, I had a hard time finding my way
around the filesystem, and discovered that I often had to find
a file for some reason or other. I knew the find command was
out there, but remembering all the options required to make it
search the right places, find the right files, and print the
right answers was something I couldn't do, at first. So I made
up my own command, using a shell script, and called it "fnd".
"fnd" takes one argument, the name of the file you want
to locate, complete with any wildcards you may wish to include,
and pipes its output to "less", which then allows you to view a
large list of results. What you get, on each line of output, is
the complete path to anything which you're looking for! I
find it amazingly useful (as is a rough familiarity with the
"less" command.) Here's my script:
That's it! The -iname option tells find to be case insensitive,
the $1 is a variable which subs in your commandline argument,
-mount tells find not to descend directories on other file systems
like your cd-ROM (because mine is wonky and locks up the machine if
it is accessed;). The -print option is required or you don't get
any output! (Get used to it, it's *nix...) The | symbol tells
find to direct its output to the "less" command so you can see
your results in style! Don't forget the / right after the find
command, or it won't know where to look. - Enjoy! You won't
regret the time you spend keying in this little shortcut, and
don't forget to put it in a "bin" or "sbin" directory after
chmod'ing it to be executable.

Hi Marjorie,
First of all, I think it is wonderful that John devoted that much of
his spare time to start and maintain the Linux Gazette. I am happy to
see that it is being continued. Keep up this beautiful project!
I was very pleased with Leifs Queue-R-Mail Howto, published in issue 6
of the Gazette, but I was still left with one drawback. I have a PPP
dialup account at a local provider, and when sending remote mail, the
"From" address and "Return Path" should be masqueraded to match my address
at the provider. If I would fill the $M macro in my 'sendmail.cf' (as
installed by Slackware 3.0), it would only change my domain, so it needed
some adjustment. I made some direct changes to 'sendmail.cf', but I did
make a backup before trying anything! Here are the changes I made:
First of all, I filled the $M macro for masquerading my domain and added
a $N macro for masquerading my username:
Disable masquerading for the local mailer in ruleset 40:
Include username in remote mail masquerading (rulesets 31 and 61):
If you send your mail as root, you might want to remove its special
treatment:
After sending 'sendmail' a HUP signal, my mail got masqueraded so that
the receiver could just reply to the correct mailbox.
Well, those were my $0.02. I hope it was still readable.
Cheers,
Hello,
Since this FAQ is comes up a very often in comp.os.linux.*,
and since it's already mentioned in kernels 2.0.12+ in
/linux/Documentation/Changes and in some News papers
(still one contacting me today: The editor of the german magazine
UNIXopen.) without any request from us.
So I'm going to ask for you to put something in your interesting
magazine. It's is how to avoid a lot of problem when upgrading
a Linux box. There's a easy way, and some scripts to run.
All the stuff is free, and is available by ftp, located at:
ftp://ftp.wsc.com/pub/freeware/linux/update.linux/
The upgrade is full, it means it will upgrade any system
from 1.2.x (sorry I didn't test any earlier setup).
It will be right for anyone from new Linux users to experts
(no knowledge is required, no questions are done: all
is detected and worked fine for all people who tested,
except non-Lilo users since I force Lilo v19 to install.
This will change next.)
All the upgrade is always up to date, and only fully tested
packages are included (!). For example, I didn't install
kernel 2.0.5 when it comes out since I've found out a bug
in the code (reported to Linus who did 2.0.6 as a patch).
Current upgrade contains:
All is NOT installed when requested. For more details,

A new release of the GNU id utilities is available at
ftp://ftp.gnu.ai.mit.edu/pub/gnu/id-utils-3.2.tar.gz
GNU id-utils is a package of simple, fast, high-capacity,
language-independent identifier database tools. Actually, the term
``identifier'' is too limiting -- ID Utils stores tokens, be they
program identifiers of any form, literal numbers, or words of
human-readable text. Database queries can be issued from the
command-line, or from within emacs, serving as an augmented tags
facility.
Release 3.2 fixes a nasty bug in eid (a.k.a., "lid -R edit"), which
should only be a problem for users of non-emacs editors (e.g., vi).
This release also fixes as well as some minor portability problems.
If you use emacs and had no trouble compiling 3.1, there's no reason
for you to pick up this release.

incorporates many enhancements and features. The last official release was
1.3. Since, a major user interface rework has been done and many smaller
features were added. Release 1.4 and 1.5 were only released on the
linuxconf mailing list.
It has been uploaded to sunsite in the pub/Linux/Incmoning directory and
should move to /pub/Linux/System/admin/linuxconf-1.6.src.tar.gz. Binaries
for both elf and a.out systems are provided at the same place.
The major enhancement is the http mode. With this, you can now operate
linuxconf using any web browser supporting forms. This makes
administration of large linux networks a wonderful experience. You can
navigate in linuxconf and even set bookmarks in your browser. Ultimatly
one can build his corporate administration page with link to different

Of course, you could spend a couple of hours every month or so and run ldd on
each and every executable on your system, writing down the results for every
one which has errors. This could become tedious, I imagine.
Peter Chang is evidently a
whiz at cobbling together shell scripts which use various Unix utilities
chained and piped one to another. Binstats is one of his, and it is
truly an ingenious contrivance. You start it up (after editing it so that it
knows where all of your /bin directories are), the hard disc grinds away for a
minute or three, and this little script presents you with a list of all the
poor orphaned programs which can't run due to a lack of shared libs. It also
lists how many of each type of executable (ELF, QMagic, statically linked,
etc.) you have, and which shared libs you have which aren't needed by any of
your executables.
What really blew my mind was seeing a long list of duplicated executable
names, an unexpected result of many upgrades. This can be a result of this
imaginary scenario: Joe has been maintaining Package X for several years and
is weary of the constant email. He gratefully transfers the maintenance of
Package X to an eager, energetic young programmer, Ed. Ed is appalled to
find an installation procedure which doesn't follow the Linux Filesystem
Standard, and immediately changes the default installation directory from /bin
to /usr/local/bin. Yours truly logs in at sunsite.unc.edu, finds a new
version of Package X, installs it, and is happy to see the new functionality.
Unfortunately the old Package X executable is living out the remainder of its
days, unknown to all, in /bin. Then Binstats does its work and the old X
binary and all its hoary cohorts are brought to light.
All of the functions of Binstats can be done "by hand", of course. The beauty
of this shell program is the combination of tasks into one, with the results
logged to a text file. Then you can see at a glance several system
administration jobs which should be taken care of.
Binstats is only four and one-half kb. archived in tgz format. A copy of the
latest version is available at this UK site,
as well as in this
sunsite directory. It's well worth the short download time, even if you
only run it once.

Binstats: Finding Unusable Binaries
by Larry Ayers
Published in Issue 9 of the Linux Gazette
Like many other Linux users, I've strayed from the path of my originally
installed distribution (Slackware 3.00) and have updated quite a large
percentage of the packages and libraries. This can lead to problems; these
might come my attention when starting up a long-neglected executable only to
receive a message indicating that an essential library is missing, or that a
library has an incompatible executable format.
The Easy Way to Set Up a Local News
Server
Introduction
A few months ago, I decided to set up a local news server on my Linux Box, in order to read off-line the articles. Before then I read the news directly from the Usenet server of my Internet Provider, at the detriment of my phone bill...(Here, in France, even the local communications are rather expensive)
Before trying to install and set up one of the two classical news servers (Inn and CNews), I browsed a bit the Web, looking for a possible other product. I then discovered a very powerful small package "Leafnode" written by Arnt Gulbrandsen. It can be found in source form at ftp://ftp.troll.no/freebies/leafnode/ and the home page of this project is accessible at http://www.troll.no/freebies/leafnode.html.
This package (leafnode-0.9.tar.gz, 29 Kb) contains three little programs, very easy to install, and to use:
The main advantage of this system, is the transparent way it is inserted between the remote news server and the local newsreader. The remote Usenet server sees Leafnode exactly like a classical newsreader (like tin, trn, netscape,...) and the local news reader sees Leafnode just like a USENET server.
I have been happily using Leafnode for several months, and I would like to describe here the (very simple) steps to install and configure it. Then I will explain some hints to use it in a multi-users environment.
I've been using leafnode 0.8 for a few months, but I've recently upgraded to version 0.9. The process for installing it is the same as the previous version, but I've had a little problem, maybe due to my version of make, and I'll describe how I have fixed it.
You first need to download the source code from ftp://ftp.troll.no/freebies/leafnode/. You'll get leafnode-0.9.tar.gz.
Become root and do :
# cd /usr/local/src # tar -xzf ~/leafnode-0.9.tar.gz # cd leafnode-0.9/ # make
Everything must compile without any problem...
Make sure there is a "news" user and a "news" group on your system.
Then you can type:
# make install
If "make install" complains when making directories in /var/spool/news/message.id/, you may have the same problem as I've had. To fix it, I've modified the Makefile, to insert a part of the leafnode-0.8 Makefile:
replace the lines (in the "install:" section)
cd $(SPOOLDIR)/message.id
for a in 0 1 2 3 4 5 6 7 8 9 ; do for b in 0 1 2 3 4 5 6 7 8 9 ; do \

Be sure that the first character on the line is a tabulation. Then try again:
# make install
At this point, Leafnode will have installed the following files on your system:
/usr/local/sbin/fetch
/usr/local/sbin/leafnode
/usr/local/sbin/texpire
/usr/local/man/fetch.8
/usr/local/man/leafnode.8
/usr/local/man/texpire.8
/usr/lib/leafnode/config.example
/var/spool/news/ ... and a lot of subdirectories ...
First you have to copy the file /usr/lib/leafnode/config.example to /usr/lib/leafnode/config and edit him, to put the name of your remote NNTP server in place of:
server = news.hiof.no
Edit the file /etc/inetd.conf, and look for a line like:
nntp stream tcp nowait root /usr/sbin/tcpd in.nntpd
then modify it like this:
nntp stream tcp nowait news /usr/sbin/tcpd /usr/local/sbin/leafnode
Depending on your configuration, there may be no TCP wrapper installed, so you could have to remove the "/usr/sbin/tcpd" part of this line.
and do
# killall -HUP inetd
Connect to your Usenet provider, and, while being "root" or "news", run:
$ fetch
You will have to wait for a moment, because Leafnode is asking the NNTP server the list of all the active groups. Once fetch ends, run a newsreader, as normal user, and ask him to contact the localhost. for example, with tin do:
$ export NNTPSERVER=localhost $ tin -r
(With Netscape you have to put localhost in "Options/Mail and News/Servers/NNTP server")
You will get the list of all available newsgroups, then choose interesting ones, and read them. They will appear empty at this time. It's normal.
As root run again fetch. It will download all the content of the previously read newsgroups. The first downloading will take a while, but the next will obviously be very much quicker.
Your local USENET server is installed!
Now that leafnode run on your Linux box, you can configure some details:
In the file /usr/lib/leafnode/config, there are two fields you can edit:
Refer to the comments in this file to choose the values (on my system I use expire=10 and maxcount=3000)
You must run Texpire from time to time, and a daily entry in the crontab seems to be the best choice:
00 03 * * * news /usr/local/sbin/texpire
This line is for a system-wide crontab (generally /etc/crontab maintained by root), but you will have to remove the username "news" on user crontab (/var/spool/cron/news).
You will have to run periodically fetch. If you have a permanent link with your news server, there's an obvious solution: the crontab again, to run it once per hour for example.
00 * * * * news /usr/local/sbin/fetch
If you're using a non-permanent PPP connection, you can insert fetch at the end of the ip-up shell script (see Linux Gazette 7 "Setting up PPP's ip-up and ip-down scripts!").
Put the name "localhost" in /etc/nntpserver or set the
environment variable (for example in /etc/profile):
export NNTPSERVER=localhost =
There are problems to avoid, especially if there are other users on your system, or if the leafnode server is on a local network. First you must make sure of the validity of the headers in the outgoing posts, but you also need to limit the list of the accessible newsgroups. Don't forget that Fetch will download the whole content of a newsgroup if someone tries to read it. So, be very careful with newsgroups like alt.binaries.pictures...
Fortunately, we can use some little awk and shell scripts to verify and correct the outgoing posts, and to limit the local access to selected newsgroups.
With some newsreaders, the "From:" field of the outgoing articles will be set to myname@my.station.on.my.lan and not myname@my.internet.provider.com. With some of them you can configure the "From:" and "Reply-to:" fields, while the others need you to recompile them.
This problem can be worse if you have a Linux box with several users. Some of them can have misconfigured newsreader (sometimes on purpose...) and it may be safer to check the headers of the outgoing articles before posting them.
Here's a small awk filter which allows a kind of masquerading of the
"From:" line of an article. It will change the line
"From: username@my.station.on.my.lan (user real name)"
to a line
"From: username@my.internet.provider.com (user real name)".
You may also ensure that username is correct (i.e. in a list of allowed users). The same Perl script will help us to determine the correct articles. Otherwise it will add a line "*** Wrong From field - This article must be deleted ***" to the message.
#! /usr/bin/gawk -f
#
# /usr/local/sbin/change_article_from_domain
#
# awk script to change the domain name on the "From:"
# line of outgoing articles.
# If the username is not valid a message will be added
# at the bottom o the file, allowing a 'grep' to delete
# him.
BEGIN {
# replace with the correct domains
local_domain="my.station.on.my.lan"
real_domain ="my.internet.provider.com"
# insert here the name of your users allowed to post articles
# (may be just one)
valid_usernames["user1"]
valid_usernames["user2"]
must_be_deleted=0
}
/^From:/ {
gsub(local_domain, real_domain)
username=substr($2,1,index ($2, "@") - 1)
if (! (username in valid_usernames)) {
must_be_deleted=1
# you can also add a system command
# example : mail to newsmaster with
# the username of the wrong article
}
}
END {
if (must_be_deleted != 0) {
print "*** Wrong From field - This article must be deleted ***"
}
}
{
print
}
This script can be useful if you have up to, say, ten users, otherwise you'll need to improve it in order to read the list of allowed users in an otherfile for example.
Now we will execute the above script on all the outgoing articles, sitting in /var/spool/news/out.going, then delete (or move to another directory) those with bad usernames.
#! /bin/bash
#
# /usr/local/sbin/modify_outgoing_articles
cd /var/spool/news/out.going
for i in * ; do
/usr/local/sbin/change_article_from_domain < $i >/tmp/modified_articles/$i
done
rm -f *
mv /tmp/modified_articles/* .
rm -f `grep -l "*** Wrong From field - This article must be deleted ***" *`
(The backquote is used to catch the result of grep) Don't forget to create a /tmp/modified_articles/ directory. This script cannot prevent the fake "From:" lines, when an authorized user is hidden behind an other correct username. This can not be easily done, and if you really don't trust your users, you'll have to use another Usenet package like Inn or Cnews.
Now all the outgoing articles will have a correct "From:" line.
The second important point to check out is the list of fetched newsgroups.
If you haven't got a huge disk
space, it would be better to avoid downloading alt.binaries groups
or alt.2600. for example...
The problem is that fetch will download the content of each newsgroup
corresponding to a file in /var/spool/news/interesting.groups, for
example /var/spool/news/interesting.groups/comp.os.linux.announce
A file in this directory is touched by leafnode every time a user tries to read the content of the group. Are you sure that none of your users will try to have a look at alt.binaries.pictures.erotica...? So there are two possible solutions:
#! /bin/bash # # modify_interesting_groups cd /var/spool/news rm -f alt.* rm -f *windows* ... touch comp.os.linux.announce touch comp.windows.x.announce ...
you can also have a definite list of fetched newsgroups, for example in /var/spool/news/official.list, manually created:
# mkdir /var/spool/news/official.list # cd /var/spool/news/official.list # touch comp.os.linux.announce # touch comp.os.linux.answer # touch comp.lang.c.moderated ...
And this list will be copied in the interesting.groups directory by a script before each execution of fetch.
#! /bin/bash # # modify_interesting_groups cd /var/spool/news rm -f * copy /var/spool/news/official.list .
Now we have two scripts to insert before running fetch. For example in /etc/ppp/ip-up:
#! /bin/bash # # /etc/ppp/ip-up ... /usr/local/sbin/modify_interesting_groups /usr/local/sbin/modify_outgoing_articles fetch
I think that Leafnode is a very interesting package for those (most of us) who are running Linux on a standalone box with intermitent connection to a Usenet server, or on a small local network with few users. It's powerful and much simpler to install and to configure than Inn or Cnews, designed for bigger sites. Moreover it does not require any maintenance.
Christophe Blaess (ccb@club-internet.fr).
I had a look at a few other file managers for Unix/X11 but none of them were even close to the convenient two-filelistings-and-command-buttons concept. Some were bloated, some wouldn't compile, some needed Motif etc, and none were intuitive (to me :-). So I set out to create my own. Why am I just not a happy TkDesk user? Well I started working on FileRunner long before TkDesk came out and TkDesk wasn't quite what I was shooting for so I continued on FileRunner. That also gave me exactly the file manager I wanted, of course :-)
After I read the above explanation, I realized what FileRunner reminds me of: I used to use a Norwegian OS/2 filemanager called Dirmaster, which was also inspired by the Amiga filemanagers of yore. It had a layout similar to FileRunner's, with programmable function buttons and twin directory panes.
It's interesting that software has been around long enough that traditions have evolved. In the text editor world there are emacs, vi, and "windows/CUA" strains of editors, while many filemanagers have followed either a "Norton Commander" tradition, an Amiga tradition, or a mouse-based iconic tradition, with various hybrid strains emerging and recombining.
FileRunner is a much less resource-hungry application which starts quickly and lends itself to quick tasks followed by dismissal. It uses around one-third the memory TkDesk uses. It is probably a more appropriate choice for a slower, memory-constrained machine, whereas if you have a fast CPU with plenty of RAM TkDesk or Moxfm will run well without using a disproportionate amount of your system resources.
Among the many thoughtfully designed features in FileRunner, the following I
found to be particularly useful:
FileRunner also has a feature which has become fashionable lately in many of the newer apps: quick rereading of the configuration file(s), allowing customization to be done quickly. I first saw this in Fvwm; it's a real time-saver.
When using the FTP function, any downloading activity prevents you from doing anything else until its done. A separate process or thread would be nice for this. One way around this limitation is to open another instance of FileRunner. The program is small and fast enough that this is feasible.
Aside from these two minor complaints, I found the program to be stable and reliable. It's a relatively small download; why not give it a try?
Happy as can be, I am composing this in Linux on StarWriter, the extremely capable word processor that is part of the StarOffice 3.1 suite of business applications. Below I will guide you through the labyrinth of tricks and fixes that you will need to get this first beta of StarOffice working on your Linux system.
Star Office 3.1 is a suite of office productivity applications containing StarWriter 3.1 (word processor), StarCalc 3.1 (spreadsheet), StarDraw 3.1 (graphics and presentation package), StarImage 3.1 (image manipulation) StarChart 3.1 (bar-, pie- and other charts) and StarMath 3.1 (formula design). StarOffice 3.1 makes heavy use of common code in shared libraries, therefore using relatively few resources for the level of functionality.
If you don't have the patience to fix things that aren't right, you should wait for the next beta release. But if, like me, you don't mind fixing a few things to get the immediate gratification of state-of-the-art business software on Linux that you would pay $400 for on Windows 95, read on.
To save you frustration and disappointment, I must also caution you that you will need about 200 megabyes on your hard drive to install StarOffice the way I outline below.
Like many Linux users, I was delighted when the German company StarDivision announced it would release an international Linux version of its major office suite StarOffice, which competes head to head with Microsoft Office in Europe. And still more pleased when I learned that for non-commercial use StarOffice would be free.
I am almost never, however, the first to jump into a new application. Let others find the bugs; let me find a productive application is my credo.
Nevertheless, the prospect of having a high-end WYSIWYG word processor to use in Linux was irresistible. When StarDivision was pressured into an early release of the first beta of StarOffice 3.1 for Linux on July 31, I rushed up to the StarDivision Home Page at http://www.stardivision.de/index.html and linked to one of a number of possible download sites which in my case was ftp://ftp.io.org/pub/mirrors/linux/sunsite/apps/staroffice.
What I saw stopped me. StarOffice3.1 is a more than a 40Mb download in 53 files, mostly diskette images. The installed product takes over 120 megabytes.
I decided to see what the feedback was on StarOffice before investing in that kind of bandwidth. I aimed my Netscape newsreader for a place I knew I could count on: comp.os.linux.development.apps.
The news was bad. Many users were having problems installing StarOffice and those who could were finding lots of bugs, mostly segmentation faults.
The worst news of all was being reminded that StarOffice 3.1 requires Motif 2.0. Even though StarOffice was free, it did not seem worth the $100-$200 investment in Motif 2.0 to bring up an application that might be useless because of segmentation and other faults.
As the days passed, however, the news began to come in that some were getting StarOffice installed and were quite thrilled with its look and feel.
Then on August 18 Peter Klein wrote in the Redhat-List:
"to run and even to install Star Office 3.1. you don't need Motif."
I found his tips and tricks irresistible. I decided to try StarOffice.
Below is step-by-step how I installed StarOffice 3.1 on my Red Hat 3.0.3 system with Metro-X server upgraded to the 2.0.10 kernel using Peter Klein's recipe garnished with a few additional tricks and fixes which I gleaned from the usenet and mailing lists.
(The 'staroffice.README' mentions that you can install only part of StarOffice. So my first attempt, not recommended, was to install just the common files with StarWriter. Unfortunately, the install program comes to an error which has to be stepped past each time it finds a file from the complete package that is missing. After clicking 'ignore' with my mouse for the first hundred or so times, I abandoned this attempt.)
cp ~/download/staroffice/file.01-? ~/so-temp cd ~/so-temp unzip file.01-1 unzip file.01-2 unzip file.01-3 unzip file.01-4 unzip file.01-5 unzip file.01-6 unzip file.01-7In the ~/so-temp file you now have a bunch of subdirectories with the unzipped files in them.
mkdir /usr/X11R6/lib/so-libs.
cd /usr/X11R6/lib/so-libs ln -s libso312.so libMrm.so.2 ln -s libso312.so libXm.so.2
/usr/X11R6/lib/so-libs
Thank you Peter Klein.
At the end of Install, I was given directions for proceeding with the second part, the user installation. During the user installation, a user-specified directory and configuration files are created for each user. I found it very easy to just follow the directions in the dialog boxes. I answered 'yes' to the prompt to copy the templates and demo documents to my directory tree because I had been informed that if I answered 'no', I would not be able to modify these documents, although I could still access them as read-only master copies.
Logged in users must get permission to use StarOffice's fonts and other files. Log ('su') into root, and
chgrp -R users /usr/local/StarOffice3.1/Xp3.J. Maynard Gelinas proposed the alternate
chmod -R a+r /usr/local/StarOffice3.1/Xp3for this fix on the Red-Hat List.
mkdir /tmp/XpSp_ mkdir /tmp/Xp_ mkdir /tmp/XpSp_/tmp mkdir /tmp/Xp_/tmp chgrp -R users /tmp/XpSp_ chgrp -R users /tmp/Xp_
While logged as root, I added the lines:
/usr/local/StarOffice3.1/linux-x86/bin/svdaemon & /usr/local/StarOffice3.1/linux-x86/bin/svportmap &to my /etc/rc.d/rc.local.
. ~/.sd.shand rebooted my computer.
And, if you followed along with me -- you are finished! All the download and intermediate directories can now be deleted. (Wait a few days, in case you find you have to redo something.)
Log into your user account, 'startx' and open an 'xterm'. The StarOffice applications start at the command line with:
swriter3 scalc3 sdraw3 schart3 simage3 smath3You will find bugs in this release of StarOffice. But by experimenting, you will also find work-arounds.
For example, I found that exiting the search and replace dialog in StarWriter
would generate a fatal segmentation fault. But by activating the cursor in
the search area and pressing Also, when you use the scroll bar, StarWriter loses its blinking cursor. I
just go to the menu bar and activate a pull-down menu and then click my mouse
in the document area. Wherever the mouse touches down places the blinking
cursor.
For printing on my Postscript printer I have found that I need to set the
printer to 'NULL' and the default options to 'lpr'.
There is a neat little button bar, 'soffice3', that is designed to coordinate
all these applications. Unfortunately, bugs make it unfunctional. So look,
but don't touch until the next release.
Tip of the day for enjoying StarOffice beta one: save your work often.
StarDivision operates a news server with StarOffice newsgroups at: StarDivision is eager to get your bug reports at: I congratulate the vision of StarDivision to recognize that Linux is an
important platform for major application development.
This has led to the development of "meta-formatting" systems, which allow one
common text mark-up system to be output in several formats. An example is
SGML, which is very capable but hardly intuitive.
Karel Kubat, a Dutch programmer, has
written a new text formatting system which he calls YODL, for Yet OneOther
Document Language. (I get the impression that the awkward "oneother" word
construct exists because Mr. Kubat wanted to have .yo as a filename
suffix, rather than .ya.)
YODL is very well documented, and the installation of the docs is an effective
demonstration of the system. The docs come in .yo source form; these files
are copied to /usr/local/yodl/doc, and then YODL is run on them during the
installation, with the end result being several HTML files.
As is true with any "meta-formatter", a user is better-off knowing something
about the output format. I think it's necessary to at least glance through
the output, just to catch any obvious errors. The advantage of a program like
YODL is that it will enable you to avoid the grunt-work of starting from
scratch.
Now that Linux Journal has taken over the Linux Gazette
from John Fisk,
I plan to post a new issue of the Gazette sometime during the
first week of each month -- preferably on the first.
Whether or not I can make this happens will
depend on writers getting articles to me each month, AND on time
constraints due to my other projects for Linux Journal and SSC.
I wish to keep the Gazette both helpful and fun as John has over the past
year. And, of course, it will also remain free. Any ideas and suggestions,
as well as criticisms that you might have, for improvements to the Gazette
will be welcome. Most of all, I will welcome your contributions -- after
all, without you Linux Gazette would disappear.
I'd also like to thank our webmaster, Michael Montoure, for his invaluable
help in checking the HTML and designing neat graphics.
In the hopes that everyone had a nice Labor Day weekend, I thought I'd tell
you about mine. I went camping in Northern Washington and Canada with
my husband, Riley, our son, Keith, and Keith's dog Lucky. We had a grand
time exploring the Okanagan Lake area of British Columbia. In driving to a
campground
on Pennask Lake, we traversed what must be one of the worst roads in Canada
-- thank goodness for high clearance vehicles! Keith was ahead of us in his
4 wheel drive truck, and was really bouncing through the ditches and holes
in the road. Our camper was bouncing and swaying enough to make me worry
that it might cause us to tip over -- Riley assured me it would not. At any
rate, after
30 minutes of hard driving, we reached the beautiful lake only to find the
campground full of fishermen. So we headed back out that wonderful road,
looking for side roads, and anyplace that we might camp. We found a place
down a side road that had only two huge ditches across it, and set up camp.
No bears showed up to spoil the fun, so we had a very
good time playing in an isolated spot away from other campers.
Canada is certainly
a very beautiful country, and the British Columbians very friendly. This
jaunt was not our first trip to Canada nor will it be the last.
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.

I am still getting my feet on the ground in StarOffice. But I found
composing this article in StarWriter quite easy and fun. I used a lot
of cut and paste between multiple windows, formatting, changing fonts,
printing, search and replace -- all the basic things you do in word
processing. But I didn't even scratch the surface of the capabilities
of just StarWriter. And I haven't even looked at the other applications
yet. I am looking forward to exploring StarOffice in the coming months.

As you can see the tags are in an abbreviated verbal form, which makes them

This allows you to concentrate more on content rather than structure; the

are noticeably easier to read in their source format than either HTML or Latex
