No, I can't get it to work. I found a good guide at
<http://www.novell.com/communities/node/4753/netconsole-howto-send-kernel-boot-messages-over-ethernet>
and adapted it for Debian but absolutely no messages appear. I connected
it via Ethernet to another netbook which runs Ubuntu. On the Debian one
(the one with the problem I want to debug) I added to
/etc/network/interfaces:

auto eth0
iface eth0 inet static
    address 10.0.0.20
    netmask 255.255.255.0

and on Ubuntu:

auto eth0
iface eth0 inet static
    address 10.0.0.10
    netmask 255.255.255.0

On the Debian one I added netconsole to
/etc/modules and created /etc/modprobe.d/netconsole.conf containing:

options netconsole netconsole=4444@10.0.0.20/eth0,6666@10.0.0.10/00:1E:68:DD:DB:40

On the Ubuntu one I ran:

nc -l -u 6666

I've double-checked the addresses etc and verified that the link is up
and the netconsole module is loaded, but no messages appear.

I tried to reconfigure rsyslog to sync on each message but it didn't log
anything useful :-(.
