Thanks Jeff for your answer, but the problem isn't in the list that
you wrote.
I add new user john in host1, and I run my program with it and
with user john in host2. Everything ok. But now, when I try to use
user peter in host2, LAM says: Permission denied. The .rhosts is
right, I modified it. The permissions on anyprog are 777, 100%
executable :D.
Somebody can give an explanation to this?
Somebody has used LAM/MPI with different users in the same
host or different hosts?
Jeff: I use 6.5 because I will execute my program on existing
LAN where I am not root, but I test the program in my home.
Thanks in advance
