Ok, followed these suggestions, and now no "Network unreachable" message. Thanks! However, I still can't seem to access the network.

Well, the only place that 128.122.154.50 shows up is in /etc/hosts. The above behaviour still occurs with another IP that is *not* in /etc/hosts, in fact as long as the IP has 128.122.*.*. And, if I use a hostname, I get:
[ root@cognilap ~]# ping calaf.cns.nyu.edu ping: unknown host calaf.cns.nyu.edu Lyle
