This is an interesting failure; it works sometimes for me (on Win2K
the command is "ping -l 1520 clio.rice.edu") but other times it fails.
I'm not sure it's related, since I can immediately ftp to the system.
It seems any value around 1472 or less results in complete success on 
ping packets, but over that value there are many lost packets.

There is a firewall at Rice which blocks many ports.  It's possible the
admins have decided certain IP address net-blocks shouldn't FTP in, but
that's a wild guess with no proof.
