Hi,
I'm using kernel 2.6.26-2-xen-686 with Debian Lenny.
I was following the tutorial at http://library.linode.com/networking/se ... bian-lenny except I get this warning on startup:
Code: Warning: weird character in interface `eth0:0' (No aliases, :, ! or *).
My first thought was I made a typo using ethO:O instead of eth0:0 but that doesn't seem to be the case.
Additionally I don't think the firewall starts up. I don't see any arno-iptables-firewall using htop after running:
Code: sudo /etc/init.d/arno-iptables-firewall start
Here is the entire output:
