Dear happy Debian users, After the update of ssh to version OpenSSH_3.4p1 Debian 1:3.4p1-1, SSH protocols 1.5/2.0, with passwordless connection through the cluster's nodes, (see archives around 20 Nov 2002) I have already some problems...
Jobs running on 1 processor works fine. But jobs running in parallel stops abnormally returning me an error: pc001: Connection refused (where pc001 is one of the nodes) I use OpenPBS and I don't know what do do... Before the update everything worked fine. If I connect manually on any node it works. I don't see in my ssh configuration files what forbids a multiple connection. Does anybody have an idea? Thanks in advance Fabrice ------------ ssh_config ------------------------ # $OpenBSD: ssh_config,v 1.15 2002/06/20 20:03:34 stevesk Exp $ # This is the ssh client system-wide configuration file.
