get_hosts script is not working for me

[gentooza]

When executing a cluster of size 4, for example, get_hosts returns the 4 machines and also:

a.root-servers.net

This line must be manually removed by me, saved in a machinefile, and executed by:

mpirun -f machinefile ./mpi_hello_world

For being able to execute programs

I think it could be fixed removing last dig command in the script, but I supose it was useful for something

cheers!
