It’s also helpful to trigger a kernel message to see if netconsole is logging properly.

One way to do this is to enable sysrq (‘echo 1 > /proc/sys/kernel/sysrq’, or configure via /etc/sysctl.conf), then trigger sysrq’s help output: ‘echo h > /proc/sysrq-trigger’.

This should log sysrq’s help output on your configured logging host, and is unlikely to affect system stability.

One small note: In RHEL/CentOS 4, you’re looking for /etc/sysconfig/netdump (and /etc/init.d/netdump) rather than netconsole.

The above configuration is not working in Fedora Core 10 with 2.6.28 and 2.6.30 kernel versions.

Please let me know the correct procedure for the above kernel versions.

Thanks and Regards,
