[mpich-discuss] Could not resolve hostname

Hi, I installed mpich2-1.4.1p1 on CentOS 6.9 following the README instruction. Configure, make, and make install steps went fine. But, when running CPI example on local machine, I got: $ pwd /home/ffan/Downloads/mpich2-1.4.1p1 $ mpiexec -n 2 ./examples/cpi ssh: Could not resolve hostname CentOS-6.localdomain: Name or service not known What could have been wrong? Thank you very much for your help.
