Default System logging not working.

Hi,

On my Redhat 9 machine, I recently noticed that during bootup the
"Starting system loggin" says FAILED. I have looked at
/var/log/messages and I see that not messages older than about 3 days
are in the log. I cannot recall anything specific I did to cause the
logging to stop working.
I have not touched etc/syslog.conf. Can anyone suggest on how to
get this working again ?

Regards
Anton Erasmus

Start syslogd manually and look for error messages.

It says syslogd already running.
At startup it still says FAIL as the result for "Starting Syslog".
Nothing is being added to /var/log/messages.
Anyway, at least together with man syslogd, I have some direction
in which to search for the problem and solution.

Thanks

If you use ps -ef | grep syslog do you see it working? What if you
try to kill it and then restart it?

Logged in as root on tty2 I get:
3130 tty2 S 0:00 grep syslog HOSTNAME=duzi.antera.net
PVM_RSH=/usr/bin

If I do:
kill 3130
I get:
No such process

If I do:
kill -SIGHUP 'cat /var/run/syslogd.pid'
as suggested by the syslogd man file to
restart syslogd
I get:
cat /var/run/syslogd.pid: no such pid.
If I do:
cat /var/run/syslogd.pid
I get 2061
If I do:
kill -SIGHUP 2061
I get just the normal prompt.
If I then look in /var/log/messages I actually
get a line indicating that syslogd has been restarted.

And if you ps -ef | grep 2061 (or whatever PID is in the /var/run/syslog.pid)
what you see?

So it looks like is started and running, but is not logging anything.
Maybe is a problem in the syslog.conf file. Have you checked it?

Below is a transcript of what I get.

[anton@duzi anton]$ tail /var/log/messages
Sep 28 12:30:35 duzi syslogd 1.3-0: restart.
[root@duzi anton]# cat /var/run/syslogd.pid
2061
[root@duzi anton]# ps -ef | grep 2061
root 2061 1 0 19:32 ? 00:00:00 syslogd -m 0
root 3065 3032 0 20:34 pts/1 00:00:00 grep 2061
[root@duzi anton]# tail /var/log/messages
Sep 28 12:30:35 duzi syslogd 1.3-0: restart.
[root@duzi anton]# kill -SIGHUP 2061
[root@duzi anton]# tail /var/log/messages
Sep 28 12:30:35 duzi syslogd 1.3-0: restart.
Sep 30 20:34:46 duzi syslogd 1.3-0: restart.

I have not touched the syslog.conf file. It should be as originally
installed. I have another RH9 box, where the syslog works as
it should. I will copy it's syslog.conf file to the box that is giving
problems.

It looks like it's working, the -m disable the insertion of a "mark"
message every x minutes, the default it's 20 minutes, setting it to
0 disable it.

If you didn't changed it, maybe someone else did. I'd test for
rootkit on that machine.

The problem is that it is not logging anything. At startup the syslog
process startup is reported as FAILED. It works fine after
I do the kill -SIGHUP pid command. (Until the next reboot)
I switch this machine off every time after I have used it, hence
a working syslogd directly after startup would be nice.
Anything else failing normally writes to the log file. With the actual
logging not starting up, where does one look ?
the kernel log seems to start up correctly. Might the reason for
the syslogd failing at startup be logged here ?

I am the only person with access to this machine. I am as close to
100% sure as can be that no-one except myself have ever used
the machine. I had been playing with some source and binary rpm's
for various utilities. Can a install via rpm cause such problems ?

Check in /etc/rc.d/initd which script start syslogd and (eventually)
add there the SIGHUP command, I admit that isn't a really good
solution, but if it works...

COuld be, check.

It shouldn't...
