Subject: Linux (Redhat7) just FREEZES!
Date: Thu, 7 Dec 2000 15:28:37 +0100
I have a problem which makes the system to freeze (stop) just like it
would with a hardware problem, but this is not a hardware problem!
I had a chat server program running on celeron400/128mb with standard
redhat6 installation, and it used to run without stopping for weeks,
sometimes even months (it was stopped only on system reboots, or when the
power went off).
Then I moved it to a different server (celeron300/96mb/kernel2.2.17)
running redhat7 and the problems began. It caused the server to freeze,
that is to stop without no messages on the console or in the logs; it
didn't respond to pings; switching consoles was impossible; simply dead!
I thought it was a problem with my old software (exactly the same as
on the first machine, where it run perfectly), which typically keeps a few
hundred (500-900) active connections and does what an irc server does,
i.e. sends messages over tcp/ip to users from other users, or with the
hardware. CPU usage is in the range of 40-60%, the process runs on an
unprivileged user rights.
Then I moved to a different server (pentium3/256mb) and installed a
COMPLETELY NEW version of the chat software (c++ application), but the
server was again running redhat7 with kernel 2.2.17. Unfortunately, the
problem did not disappear. It caused (and still causes) the system to
freeze approximately after 1-3 days of working, on a regular basis. I've
downgraded kernel to 2.2.16, but it didn't help. RedHat7 was updateded
lately, but again without any success.
Anybody has an idea what could cause the problem? Note, that this is not a
problem of memory or descriptor leaks. In such cases the kernel wouldn't
just die without any messages in the logs or on the console.. Also note
that the problem is not with the hardware (I hope!), because it happens
on a celeron400/96mb and pentium3/256mb as well. The only thing those
servers had in common was the system (RedHat7) and my chat server software.
If possible, include CC to [EMAIL PROTECTED], please.

We're doing syslogging with syslog-ng which has a nice macro expansion
feature that will create log files for each priority level. So we have
a couple of routers logging into a /var/log/cisco directory. So here's
the dilemna I want to set up logrotate to rotate those logs, and I was
hoping that I could do it without having to specify each possible file.
Can logrotate use some sort of wildcard? Can I say rotate all file in
this directory every day, compress and keep for 7 days. Otherwise I
have to define a file for each priority level, for each router. No fun.
Thanks,
Brian Seppanen

Scary action. I would never advise anyone a command like this.
One small type (eg. a ? instead of a ~) and you'd lose a lot of data.
When you run such a command as root, you'd better be extra carefull.
just
rm -Rf \~
rm -Rf ./~
rm -Rf '~'
any of these will do (and there are more options, but why bother)

This does not appear to be true. I use tcsh, and after I have logged
in and am in an X windows session, the PERL5LIB defined in
/etc/profile is set. See the output below. I know /etc/profile is
the source of the information because I made the changes there and
noone else uses this system. However, this information is not
available to my .tcshrc file when it is first executed at login.
I will try your other suggestions.

I have a Linux kernel 2.2.12 firewall with a private network using

The man page for apsfilter should tell you where the various files are
stored. If not, you could try the locate command or find. You only
need to look in /etc and maybe /var.
Typically, these magic filters will prepend and append special escape
sequences to the file you want printed. The norm is for the appending
escape sequence is just a reset (Esc E I think). You will probably
need to change the prepended escape sequence. Right now, it probably
adjusts end-of-line behavior and probably sets a page length. Your
printer manual hopefully has a section on these escape sequences.
I suspect your top margin is a little too large, although it might be
a page length thing too. The first thing I would try to set the top
margin to zero, and see if that fixes your apparent bottom margin
problem. If not, try setting both to zero.
All the above assume you are comfortable finding and editing these
files yourself (apsfilter program files). If not, I'm not sure how
you would go about changing this.

I'm running a modified RH 6.1 setup and would like to try out
Konqueror. I have both gnome and kde installed, but the kdebase I have
includes kfm, not konqueror. Is it possible to install Konqueror
without doing a complete kde upgrade? Can it be installed as a
component, or do I have install the whole kdebase? I can handle source
or binary installations, but I don't know where to find it. The
Konqueror home page was not particularly useful, and there doesn't
appear to be a binary available via rpm finder.
Thanks for any advice/assistance,
Lori

Apparently, boot.b got deleted. Use:
rpm -V lilo
to check the integrity of the lilo package. It will probably tell
you that some files are missing. Then either in YaST or with rpm
uninstall lilo, then reinstall it. Then continue. You are using
the best approach to dual boot Linux and NT.
Good luck,

AFAIK you would need to upgrade the whole of the kdebase, NOT ONLY that, you
need to upgrade the kdelibs and QT too, you may also have to upgrade your glibc
on RH6.1, I'm not sure. It's not a simple programme upgrade. KDE 2 is a major
change, and Konqueror is an integral part of KDE. Also, it can be difficult,
though not impossible to have KDE 1 and KDE 2 in functional condition aon the
same system. I haven't tried it myself. You may also want to look into the
comp.windows.x.kde newsgroup, for more info.
Good luck, and I hope this doesn't scare you off. because KDE 2 is a major
improvement.

Because actions concerning the environment are in effect for
the duration of the script itself. Instead, you may do a
"source script-file" to execute the commands in your

Hi-
I am running the i810 chipset. If yours is set up like mine you
need:
1) to have/compile the kernel module agpart.o;
2) Set up XF86Config as:
===
...
Section "Device"
Identifier "Intel 810"
VendorName "Intel"
BoardName "810"
# 5-11-00 try adding power saving option
Option "power_saver"
VideoRam 4096
EndSection
...
===
3) The 3.3.x server is XF86_SVGA
If this is insufficient, feel free to contact me by e-mail for
more information.

I have this problem if I use ESD (which mixes audio streams to allow more
than one to be played at once over a single channel). I would suggest you
check what output plugin you are using in the XMMS preferences. (It
should probably be set to OSS).

I have carefully read the documentation & FAQs of LVM and they say
explicitly that it is possible to mount a root LVM. I have such a root,
indeed. The problem appears when lilo looks for devices recursively in
/dev
- it could also have to do with the lvm-module itself: I don't know much
about the kernel internals, but it could be possible that a module that
uses
a specific special device (major-minor pair) registers it into the
kernel as
a valid device of some sort - in this case, a disk, partition, or
something
thar can contain a filesystem.
I imagine a possibility of going around the problem, and this is the use
of
a so-called partition alias. I have read that a partition can overlap
with
another though that does not make much sense, but it is useful for the
following case:
You have a LV from which you know the exact location and length (in
units of
physical sectors;
that information is given by the program pvdisplay -v). It has to be
fully
contained within a partition and be contiguous (just like a normal
partition). Then you can define a partition with sfdisk -uS -N <number>
/dev/hda<number> which points exactly to the beginning and end of the
LV.
Now you have a partition alias for the LV. Before working with lilo you
should mount the root-alias as /, work in the runlevel S and disable
lvm.
The "root="-entry of the lilo.conf has to be a major-minor number - the
one
of your LV- , and it should boot from your partition-alias.
That could be a work-around until lilo supports lvm. What do you think
about
this approach?
