Thanks for all of you! I finally get it work now. The solution is to disable the firewall on the fc5 machine. It just blocks the mpi communication.

If you used a regular cable, strange things could happen, though I would expect nothing to work in that case... Are both machines set up with a static IP or is one of the machines acting as a DNS server? Are both machines allowing incoming traffic on that port (ie, not blocked by firewall)? Check /etc/hosts and make sure both machines know about the other? There are lots and lots of reasons you would get a "no route to host" message, these are just some offhand thoughts.
