Hello All.
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 :

mpd &
mpdtrace -l

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 ?
I really need your help .
