=='''Hack 16. SSH Session Statistics using SSH Escape Character'''==


To get some useful statistics about the current ssh session, do the following. This works only on SSH2 client.


# Login to remotehost from localhost. localhost$ ssh -l jsmith remotehost 

# 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. 

remotehost$ <nowiki>[</nowiki>'''Note:''' The ~s is not visible on the command line when you type.]

remote host: remotehost local host: localhost

remote version: SSH-1.99-OpenSSH_3.9p1 local version: SSH-2.0-3.2.9.1 SSH Secure
