here is where I think I have the problem: "netstat -at" on lamo gives
me no open ports that are due to my executing the LinkCreate command
on lamo. I suppose my firewall is too paranoid (default Fedora Core 2
settings). Would anyone out there know how to fix this? I use iptables
for a firewall.

Actually, just saying LinkCreate[LinkProtocol->"tcpip"] figures out
two random port numbers by itself.

Cheers!
