Re: My two servers not connected to SSH

Is SSH running on the 192.168.10.56 server?

 

What happens if you try 'ssh -vvv 192.168.10.56'?

Re: My two servers not connected to SSH

Typically, a connection attemp wil only timeout if there is something blocking the connection - or possibly a routing issue - if the sshd is not running in the server the client will usually get an immediate "connection refused" error.

 

Is there a firewall between the client and the server?  Ensure Port 22 is allowed through the firewall.  Is possible that pings - and other connection protocols - are alloed but not ssh.

Re: My two servers not connected to SSH

From your earlier threads, I think your uatapp2 is a cluster node, and I think it has 2 or more physical NICs.

 

This document might be very helpful:

http://mayoxide.com/presentations/Understanding_hpux_routing.pdf

 

It explains how HP-UX decides which IP address to use when it has multiple NICs and/or IP addresses available. It also describes some common problems and things you can do to solve them.

 

It is only 20 pages: I recommend you read all of it.
