Ok, but the output of ifconfig in the IP-aliasing mini-HOWTO *does*
have those lines, which confused me.

Ok, I thought (from man interfaces) that the "network" line was only
needed
for 2.0.x series kernels, I can add this.

I tried several combinations of route commands. This is the latest one
I tried:
route add -host 205.178.55.110 dev eth0:0
I also tried 'route add -net 205.178.55.0 netmask 255.255.255.192 dev
eth0:0'.

Ok. I thought blocking out the IPs was kinda traditional :) Perhaps
more
people pinging the machine would help.
New stanza in /etc/network/interfaces:
iface eth0:0 inet static
address 205.178.55.110
netmask 255.255.255.192
gateway 205.178.55.65
broadcast 205.178.55.255
network 205.178.55.0
This is right after doing a /etc/init.d/networking restart, before any
route
commands.

Thanks for all the help.
I am kinda struggling here, since I've been forced into a sysadmin role
without
any experience or training (company can't afford a real sysadmin, I'm
the only
person with *any* kind of linux experience, since I run debian at home.)
