No, I can't get it to work. I found a good guide at 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. > > > If I enable debugging is there a way to get it to sync to disc after > > > every message?

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