How are you asked? Could you get a screenshot so we can guess at which
agent is being invoked? :)

Personally, I'd open up a terminal and, while that pop-up is showing,
see what the output of
sudo netstat -ntp | grep :22
is; netstat will print out a list of current connections, and the grep
will extract those involving port 22 (which ssh uses). For example,
this is four ssh sessions I have open to a total of three hosts:
avi at fantastic:~$ sudo netstat -ntp | grep :2
[sudo] password for avi:
tcp 0 0 192.168.1.126:38334 192.168.2.48:22 ESTABLISHED 6560/ssh
tcp 0 0 192.168.1.126:33493 192.168.2.222:22 ESTABLISHED 10039/ssh
tcp 0 0 192.168.1.126:51534 192.168.2.222:22 ESTABLISHED 8758/ssh
tcp 0 0 192.168.1.126:43146 192.168.2.17:22 ESTABLISHED 28952/ssh
That line before the '/ssh' is the PID of the process with the
connection. You could grep `ps auxwww` for this. Or, perhaps, pipe
`pstree -A` into less and search for it - that way you can go back up
the process tree and see what invoked the SSH client.
