[MPICH] mpdboot error : fail to ping

[Ralph Butler]

This seems to be a new bug.  I do not want to ask your secretword,  
but will guess that it is an integer.   If so,
please make it a non-integer.  It's OK to have digits in there, but  
not to have the secretword be all digits.
Let me know if this fixes the problem and I will fix it in mpd for  
the next release.

Thanks.
