To get some useful statistics about the current ssh session, do the following. This works only on SSH2 client.
1. Login to remotehost from localhost.
localhost$ ssh -l jsmith remotehost
2. Display SSH statistics
On the remotehost, type ssh escape character ~ followed by s as shown below. This will display lot of useful statistics about the current SSH connection.
