you should lookup if your kernel is SMTP, cat /proc/cpuinfo will give you a
hint.
I only use SuSE, they have a SMTP kernel you can install on the distribution,
however
I buy the CDs, cause at home on a 64K ISDN link, that is paid metered....:-(
SuSE and other pay distros pay many linux folks, that they can work on their
projects
and that's something I like to support...
X/KDE performance is IMHO a RAM problem, with 64 MB you can't do much. Sad most
times
you have to use this "crashicator" NS thing, a memory hook....
As for your HD try man hdparm -t /dev/sd? and lookup man hdparm, but for me it
seems like you
just have not enough RAM in your box and maybe you're running the wrong kernel.
Good luck

This means I can configure the shades of color for ncurses see the
difference in any programm which uses the default-colors of ncurses. Do
you know where (name of config file)?
Besides why does bash shows much better color which probably uses the
same color sheme?

Does anyone know where I can get Vim 5.7 for Linux in rpm format that
isn't the new version of rpm (I need one that will run with <=3 for the
rpm...) I have downed the source, but can't get it to compile... get an
error message re some gui file, and can't seem to change the compile
options to get it to work...
Thanks in advance...

Every screen shot on the Helix website shows a menu at the top of
the screen in addition to the panel at the bottom. Where does that menu
come from? What program generates it? I've built most of Helix by hand
(enough to compile Nautilus, which rocks!) but I have yet to find that
menu.

Good. I certainly have no objection to script files. I use them myself
and tell people (www.theory.physics.ubc.ca/ppp-linux.html) how to write
them. Unfortunately almost all of the canned scripts make weird
assumptions (eg look at ppp-on script which assumes logon
authentication-- something few ISPs use these days).

Mandrake has a window like installer.
linuxconf is the Control Panel.
xman is the gui help system.
Task bar and desktop have windows pull downs to do what ever.
Once you are through playing around to see what you can see,
you can spinup a console/xterm and start learning as much
linux as you can stand.
After that, you can start playing with compiling the kernel.
Just for fun I did a locate bin/ | wc -l
which means locate all program/files in the *bin/ directories
and it returned 4098. I am running Mandrake Deluxe with all
4 cds loaded. For you, I would go with the 2cd for starters.
I just looked and looks like you could get Red 6.2, Man 7.1
and storm installs and source for about $12 + shipping.
http://cart.cheapbytes.com/cgi-bin/cart
under CheapBytes CDs (top left)
contains linux x86 Install cds for ~2 and up + shipping
Redhat 6.2 x86 install and doc cd ($3.45)
Linux Mandrake 7.1 (GPL Version) (~$4)
For people accross the pond, http://www.linuxemporium.co.uk
Mandrake 7.1 is based on Redhat, has more utilities a much
better user friendly installer.
Pick Workstation custom install if you do not want to wipe
you disk.
Install docs are on the cd and readable via Winxx.
For hardware compatibility
http://www.linux-mandrake.com/en/fhard.php3
http://www.redhat.com/corp/support/hardware/index.html
I get several people at work to go in on my credit card
and I get my shipping reduced to $1 a cd when we split
shipping.

AT&F1 is for Sportster modems-- it establishes harware flow control,
rather than software flow control. Other brands define it differently or
do not even have an AT&F1 command. On them AT&F or AT&F0 may be better.
But it is almost always a good idea to work off this as a base, and
institute other features of the modem. If your init string works use it.
The problem is that because each modem manufacturer instituted a
different set of commands ( and the same command does different and
incompatible things on different people;s modems) there is nothing easy
anyone can say, except start off from AT&F or AT&F1 and build up fro
mthere. Do not use ATZ.

That sounds good ( unless youreally meant to say "can't")
Anyway, what is now the error message. Really we are not capable of
reading the messages off your monitor, no matter what you have heard
about TEMPEST and other monitoring stuff.
So, if I was to be facetious, I would say"Install the sound card". But
have you checked that it is on and that the volume on the microphone
line is turned up ( eg bring up kmix or your own mixer and make sure
that the microphone is on and turned up). Do you have a microphone? ....

Hm, I wrote a shell script including a while loop. It works fine, until
one of the commands (ftp) inside the loop echos an error. In this case the
loop ends.
i) is there a simple way to keep it going on ?
ii) or do I have to include an exception ? If yep, how ?

Which is not the same environment that the crontab will be running in.
To set environment variables in cron, you must put them at the top of
your crontab.

You probably don't mean "/myscriptname" unless the script is in your
root directory. More likely you mean something like "/home/me/script".
Also, you could redirect output to /dev/null to prevent mail being sent:
myscriptname > /dev/null 2>&1

Subject: Need help in running ic over a remote X display.
Date: Fri, 22 Dec 2000 18:43:59 -0500
Hi
I have a Linux (~Red Hat 6.1) machine in my office. IC (Mentor
Graphics) is installed on Sun workstations. I tried to run it remotely
after exporting display but the program quit after errors (see below).
I think that it is a fonts problem. (I might be wrong on this). Any
advice on how to get IC running over the remote display would be
extremely welcome. The machine is on the LAN, so speed is (hopefully)
not a problem.
Thanks in advance,
