[mpich-discuss] wrong SSH user using mpdboot

Hi I compiled MPICH2 1.2.1p1 on debian 6. I'm using VMware 9. My master hostname is "debian1" and slave one is "debian2". username on master is bb1 and bb2 on slave system. when I run "mpdboot -n 3 -f ~/mpd.hosts" it tries to ssh as "bb1@debian2" and asks for password. But doesn't accept it and some error about port problem. I'm new in MPI and I don't know what is the problem. I appreciate if you can help me. <http://www.mpich.org/static/downloads/1.2.1p1/> -- Live free() or die()
