[mpich-discuss] MPICH2 on LAN with Ubuntu 12.04

[heshsham basit]

I get this on both the machines:


root at ubuntu:/home/#  getent hosts ubuntu
192.168.1.4     ubuntu
root at ubuntu:/home/#  getent hosts hesh
192.168.1.5     hesh
root at ubuntu:/home/#
which is expected- am I right?

 (one of my IP address changed as I connected to a different WLAN)
