The latest 2.3 kernels are highly experimental and don't work properly
with many filesystems. Unless you're helping to debug the kernel, it
would be best to stick with 2.2 kernels for a while, yet. Take a look
at http://www.kt.opensrc.org/ to get a flavour of what's going on
in the kernel development scene.

Part of using newsgroups is the ability to foresee which questions will

Oh nonsense.
The Soviet system was great, until it moved away from
the Soviet system and became Stalinist. Incidentally if you are into
George Orwell I suggest that you read "homage to catalonia", and "down
and out in paris and london" whilst you are there. This might help you
to understand that Orwell was actually a socialist, was decrying the
death of it in the USSR, not claiming an historical envitablity.
There are many countries which have strong socialist
traditions (including my own) and in many cases these ideals have been
incorporated deeply into the society. And most of them have not turned
into totalitarian governments.

You're going to have to find a better example. Standard Oil
controlled roughly 90% of the oil industry at the time the government
went after them. By the time of the breakup their share was down to
about 70%. Market forces were working just fine.

Subject: Safe vs fast Linux filesystems
Date: Sat, 17 Jul 1999 09:07:23 -0700
I had a problem after as power outage with my file systems.
I am using Mandrake 6.0, Cyrix 266 MHz, 32MB RAM, 4.3 GB HD.
with KDE.
On booting after the power outage there were errors with hints to:
e2fsck -b 8193 <device>
I tried this with /dev/hda5, 7 and 8 for /boot, /home and /.
This did not help.
A FreeBSD knowledgable friend said that Linux uses a fast vs safe strategy
for disks and recommended tunefs. I did not see anything in tune2fs that
related. I did find that in fstab that defaults is specified
for the disks. "defaults" is listed as being
rw,suid,dev,exec,auto,nouser,async
so I replaced the "async" of "defaults" with "sync":
rw,suid,dev,exec,auto,nouser,aync
when rebooting I got as bunch access permissions. They seem to be related to
programs running. I did include the "exec" and checked its spelling.
Any clues as to how I can get a safe vs fast file system?

Farouk, you will have to get used in using KDE. I assume, Netscape IS=20
already installed on your system.
An excellent and inexpensice book is:
SAMS Teach Yourself KDE 1.1, written by Nicholas D. Wells.
ISBN 0-672-31608-0
This book will explain you in details, how to create Kdelnks allowing=20
to launch apps....etc.
BTW: launch a research with the nifty research tool of KDE...put in=20
netscape..and you will likely get a list indicating the directories.
If Netscape is on your system, have a look under usr/bin/...there you=20
should find a binary named netscape.
To this binary you will have to create a kdelnk...

Forgive the format of these diffs, they are against ssh 1.2.26.
The changes work under linux 2.0.x (RedHat 5.1). YMMV, depending
n what version of UNIX you're running...
/usr/local/lusers is a chrooted tree.
If the user ssh'ing in is *not* in the normal /etc/passwd, they
are looked for in /usr/local/lusers/etc/passwd. If they exist
in the chrooted passwd file, they are dumped into the chrooted
area.
The above also alloctes chrooted pty's starting at a different
minor/major than non-chrooted, to avoid users snopping each other's
shell sessions...
Hope this helps,
Dave

hi,
i'm a newbie to Linux. i just installed Slackware 4.0 and i guess
i'm running the vmlinuz kernel. i was wondering how one decides

I just wanted to know why someone upgrades a kernel and if i should.

Subject: Serial Console w/ SuSE 6.1 doesn't work
Date: Fri, 16 Jul 1999 19:10:20 +0200
Hello there,
I'm trying to bring a serial console to function.
First I configured my serial port for login via mingetty. That works fine as
long as the machine runs. After reboot the init tells me about "Respawning
too fast. Disabled for 5 minutes" and in the "F9"-screen (sorry whats the
correct term for it?) it says the device /dev/ttyS0 is not a character
device. By executing "setserial auto /dev/ttyS0" and invoking "init q" the
login is possible again ... until next reboot. Any suggestions further than
executing setserial during bootprocess?
The next problem is that I want the machine to give its entire boot-messages
to this first serial port. Compiling the serial console option into the
kernel (2.2.5) does not do it. The next time I excluded the support for the
console on a virtual terminal - didn't help me out - then I found the
serial-HOWTO and the text-terminal-HOWTO. That gave me the hint to edit the
console.c file. It's a little bit better now. In lilo.conf are the right
terms set to see boot messages, but when the kernel takes over control
(right after swap is up) the boot messages switch to the virtual terminal.
May anyone help me out of this?
Thanks a lot + Best regards
Mathias

Perhaps its specific to SuSE. Basically /etc/permissions is a list
of important files and their owners and access permissions. The daily
