Hi,
I execute the parallel exemple icoFoam in parallel with 2 Pcs running red hat 9.0. At the first time it running well, but when I try to reexecute for a second time (eventually after rebooting), I received the fellowing errors:
Error: LAM/MPI unexpectedly received the following om stderr: permission denied.

For information: my network is composed with 2 Pcs, the file rhosts is located on both Pcs in /home/mer1/.rhosts and /home/mer2/.rhosts resectively with lines : 100.100.100.137 and 100.100.100.138. In /etc the two-files : hosts.allow and hosts has the same adresses IP. I do not declare any user in the lines. Now the two Pcs asked me for a password to rsh or ssh services. What wrong with my network or with LAM/MPI???

The SSH asked me at the final line for : publickey, keyboard, I can't understand what happened.

perhapse, I make mistakes during configuration of network, but I can't find where?

the file machines in /etc works well with the boot of LAM.

please help me, in more details.

thanks

Things I would check:

Hi
The sshd is running and the firewall works with medium and authorize the ssh service.
I check the hosts.allow, it seems good.
But there is a point I can't find in $home/.ssh the file related to authorization.
thanks
