What process is signaling this?
Authored by: hamarkus on Aug 19, '05 02:44:41PM

Which process is doing the ssh stuff? In other words, how do I see it when people are pounching at my door? I often have the processes 'sh', 'pmTool', 'kerneltask' taking up a lot of cycles (10% to 20%), I attribute some of these to Matlab, which might use these processes, or VirtualPC as well.

Monitoring and Delays
Authored by: lullabud on Aug 19, '05 03:06:13PM

I've actually never paid attention to what process is doing the authentication, and frankly I'm not too sure about OS X's `top` binary, but I keep an eye on my network meter for systematic looking patterns and my CPU meter for consistent CPU usage when my system should be idling. If something looks fishy I `tail -f /var/log/system.log`. (That's also handy when used with /var/log/httpd/access_log when people are hacking your webserver.)

Also, while testing to see which process would be hogging the CPU, I noticed this in the system log:

Failed Authentication return is being delayed due to over five recent auth failures for username: foo.

I wonder if there's a variable I can change to lengthen that delay....

For every ssh connection, there should be a correspondingly forked sshd instance to handle it. So the list in top or ps, look for the sshd instances.
