Top Forums UNIX for Advanced & Expert Users Help! How to find the local host after few ssh hops to remote host??? Post 302408043 by gomes1333 on Saturday 27th of March 2010 09:52:31 PM

SSH_CONNECTION gives me the last remote host from where I hopped.

I would like to find which local host initiated it. In my example, sitting on A2 host, i want to find that L1 originated the connection, eventhough i hopped to A1 first.

Now SSH_CONNECTION from A2 shows A1 and not L1.
