Are you really trying to use the wireless network? Looks like 
that's what is getting used.
 
You can use the mpdcheck utility to diagnose 
network configuration problems. See Appendix A.2 of the installation 
guide.

I have two 
  PC's with linux (kubuntu 8.10). I make a cluster using this machines. When use 
  for example the command "mpiexec -l -n 2 hostname" i can see that it's all 
  right, but when i try to send o receive some thing i have the same error. I 
  don't know why. Please i need one hand. Thanks for all.
