[SLL] Ubuntu Hardy; strange routing problem

[Jorge Restrepo]

jer at jr:~$ host lxer.com
lxer.com has address 207.210.216.38
lxer.com mail is handled by 10 dal3.wmkt.net.

I doubt the DNS server is at fault, although I need to investigate if the
DNS server in this pc is defined by DHCP...   Good point.


However,

jer at jr:~$ host lxer.com 207.210.216.38
^Cjer at jr:~$ host lxer.com  207.210.216.38
;; connection timed out; no servers could be reached


Hmmmm....
