Hi Pete --
This is usually because your MTU is set too low. What
does 'ifconfig eth0' say? MTU=64 is a common but bad value, and
gives the 'Message too long' message. Try 'ifconfig eth0 MTU 1400'.
Set your dhcp client config to ignore the MTU returned by the
(presumably crappy) dhcp server. (ie for dhcp3-client, remove
the 'interface-mtu' from /etc/dhcp3/dhclient.conf).
Or if you can control the MTU value the dhcp server hands out, set
it to something reasonable.
