Can you ping colorado.edu if you do it by IP address? (128.138.240.1)

If yes, then you need to reference a DNS server in /etc/resolv.conf.

If no, then you need to set a default route to the outside world.

On the assumption that the other computers on the local hub can ping the
outside world, I'd suggest you check their settings ('cat /etc/resolv/conf' and
'netstat -nr" on Linux, "winipcfg" on Windows, Control Panel:TCP/IP settings on
the Mac).

Here's the (edited) result of 'netstat -nr' on the computer I'm using right
now:

192.168.1.1     0.0.0.0         255.255.255.255 UH        0 0          0 eth0
192.168.2.1     0.0.0.0         255.255.255.255 UH        0 0          0 eth1
64.24.104.226   0.0.0.0         255.255.255.255 UH        0 0          0 ppp0
192.168.2.0     0.0.0.0         255.255.255.0   U         0 0          0 eth1
192.168.1.0     0.0.0.0         255.255.255.0   U         0 0          0 eth0
127.0.0.0       0.0.0.0         255.0.0.0       U         0 0          0 lo
0.0.0.0         64.24.104.226   0.0.0.0         UG        0 0          0 ppp0

Note the entry with "UG" (the "G" is for "gateway") in the fourth column. 
That's my current default route to the outside world (set by pppd on dialup).

You need a entry like that in your network tables.  You can put it there with
linuxconf (if you have it) or 'route add default gw XXX.XXX.XXX.XXX' (I think -
I'm a little weak on the usage of "route".
