Linux server locked up - No reponse. Booted up fine

[Jorge Cocomess]

Hi,

The other day, my RHAS 3.0 Linux server locked up with no response. Lucky for us, the server rebooted fine after a hard reset.

Where and how I can look for errors logging for that time?

Please help a newbie to Linux world.

Thank you in advance.

The start point for searching problems is the /var/log/messages file.

You can also instal the sysstat package and use the sar command to check performance counters what was going on at that moment.

You could configure a remote syslog server, sometimes, syslogd cannot write to disk (/var/log/messages) but is able to send remotelly via network.

Enable the Magic sysrq key.

Shalom,

I agree with Ivan on the starting point.

Your server probably ships with a bootable hardware diagnosics cd. Boot off it and test that all the hardware is working.

As always, thanks for your quick reponses.

I will look for the bootable CD and run the diagnostic check on this server.

How could I setup so that the syslog send via e-mail?

Ok, I got the idea /etc/syslog.conf -- How do you do it? What's the command?

Thanks for your time.
