How to check if netconsole really works?

view story
linux-howto

http://askubuntu.com – I installed netconsole using the instrunctions given here: https://wiki.ubuntu.com/Kernel/Netconsole dmesg | grep netconsole says everything is OK, but I won't believe it so easily:) How can I make Ubuntu generate some kernel message in order to see if netconsole really works and sends everything to the other computer? I tried: logger -p kern.alert "test message" # this apparently talks to syslog only echo "test message" >/dev/kmsg and wrote a small program that just did a segfault. All this generated entries in /var/log/kern.log, but not in dmesg and it was NOT copied via netconsol (HowTos)

Judging from http://lxr.linux.no/#linux+v2.6.32/Docu … onsole.txt 'nc' means 'netcat', not 'netconsole'.Install gnu-netcat and try again.

Randomly, but not later than after 10 hours of work, the laptop freezes. Just freezes. Knowing that not all hardware errors are reported back to the user I tried the netconsole. Unfortunately the netconsole also didn't output anything at the time of freeze.

The only correlation I've found is that usually, on next powering up (after forced powering off) the laptop consumes 10W more power.

Hi, I'm trying to set up a group of 10 Apple Xserves running Fedora 17 for a render farm.

I am getting lots of messages about tainted kernels in Fedora 18. I try to run dmesg and get no results stating where or what is the cause. I only see a message about USB storage being not tainted. Any idea what might be up with that? I'm stumped at the moment.
