You need to create a .mpd.conf file in your home directory - ~/.mpd.conf and it must contain a line:
The file must be mode 600 or it will not work. Make sure this file is shared among all the nodes.
Also I suggest using mpdboot from the first node instead of invoking mpd directly. I've had better success with mpdboot.

I have a cluster with 4 machines (fedora core 11).
I installed mpich2 - 1.1.1-1.fc11.i586.rpm .
I wrote on every machine :
then i wrote on thr Master :
mpd -h Worker1.cluster.net - p 56128 -n
I got :
Master.cluster.net_38047 (connect_lhs 944): NOT OK to enter ring; one likely cause: mismatched secretwords
Master.cluster.net_38047 (enter_ring 873): lhs connect failed
Master.cluster.net_38047 (run 256): failed to enter ring
And the same was for other machines : Worker2 and Worker3 .
For information :
I have SSH works on ..
So where is the problem ?
What i have to do ?
