..means your box doesn't know the way to mareschal. try ip-addresses

if it's ok with ip-addresses (instead of names): see /etc/nsswitch.conf
for "hosts: files dns" and /etc/resolv.conf for a valid nameserver.

seems your link is ok.
check your routing:
root@box:~# route -n
root@box:~# ip route show
there should be a route (maybe default route) to your gateway.
