Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I have 2 dedicated servers both running CentOS 5.3 and Plesk 10.0.0.

I'm trying to migrate stuff from one to the other but it's not happening, just after I fill out "Migration settings" and press "Next" I get "Host xx.xx.xx.xx is not accessible"

What I've done so far that didn't have any effect whatsoever:

stopped the firewall on the source server enabled "PermitRootLogin yes" in /etc/ssh/sshd_config and restarted the service

Any ideas?

UPDATE: I was able to initiate the migration from the new server (which is blank) to an old one (I need vice versa), so there's definitely something relating to settings.

I pulled out a log file, and this is where it fails:

The problem is solved, it's not Plesk related it's a very generic one. The new server was not able to SSH the old server because hosts.allow didn't have "all" enabled...
