newbie, PVM setup

[Heger The Horrible]

Hiya,

I am a newbie to setting up Beowulf's.
Am doing one currently for my final year project at university.

Anyway, I have installed SuSE 7.2 on 4 nodes, (P100's)., and have installed 
pvm when I was doing the installation of SuSE.

I can get the pvm>, so assume pvm is working correctly. I can conf, to see 
the master node. What I cannot do however is add hostname. When I do, I get 
this message (see below message)
I have installed pvm on the slave nodes in the same way as I did for the 
master, and can get pvm> on each of them.
I have edited hosts.equiv, and hosts.allow for each of them.

I'd be very grateful if anyone could help me. I am a newbie in Beowulf's as I 
said before, so hopefully its something simple to you guys/girls.

Many Thanks

Jayne Heger
