[ale] RH8 "Temporary failure in name resolution"

[Jonathan Glass (IBB)]

Quite frankly, your subnet mask looks wrong.  You may want to verify it.

Can you run "cat /proc/sys/net/ipv4/ip_forward"?  If it is 0, then you
are not routing on your router box.

This really sounds like a mask issue.  T U sure it is not supposed 2 B
255.255.255.254?  Do you have more than 2 usable ip addies?
