Which user are you using when you run mpd? If it is an ordinary user, you should have a .mpd.conf file under the home directory like the following:

cd $HOME
touch .mpd.conf
chmod 600 .mpd.conf

and the .mpd.conf file contains a single line:
secretword=<secretword>
which should be the same on the machines you want run into a ring.

If it is the root user, you should make a file named mpd.conf under the /etc directory. And the contents are the same as the former.

Hello All.

I am sorry for the empty message that I have sent by mistake .

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 .

Regarded .
