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 . Cry

Regarded .

Do you have your .mpd.conf file set up with a secretword and the file with the correction permissions (600)? The README has more info if needed.

Also, has it worked before but has now stopped working? If so, you can check if there are already mpd's running on the nodes (with your UID) and/or something didn't clean up correctly from previous runs. That can block launching new mpd's.

Hope some of that helps.
