I've installed the latest snapshot taken from svn developer's trunk but I had the same problems. This is my configuration:
Do you think my problem could be related with the operating system used or with any parameter or configuration? I've also checked the ssh log file but I didn't find any problem.
- Ubuntu 2.6.38-8 kernel
- Openssh_5.8p1 openssl 0.9.8o
- Libtool version 2.4
- Open mpi 1.7 rc5 and latest snapshots.
Thanks in advance

>> It seems to be working fine for me with the latest 1.7 tarball (not rc5 - I didn't test that one). Could be there was a problem that has since been fixed. We are getting ready to release an updated rc, so you might want to try it (or use the latest nightly 1.7 snapshot).

Surprisingly if I try to run my program with at most 2 hosts, and so the file hosts contains only two hosts, it works but if i try to run my program with more than two hosts i have this error; mpi works well on each machine and I also tried to run my program with different couple of machines in order to be sure that no machine could be the problem.
