ok - it looks like since I was using a 2.2 kernel that the virtual ip
stuff wasn't compiled in - so I have switched to a 2.4 kernel and all
is sweet :)
uname -r
2.4.18-686
I am probably too lazy but typing apt-get -s install kernel-image gives
some idea of which pre-made kernel to use..
hopefully this will be of use to others with similar prob..
