The man page for ssh says that there are these three commands you can run on multiplexing ssh sessions:
- "cancel” (cancel forwardings)
- “exit” (request the master to exit),
- “stop” (request the master to stop accepting further multiplexing requests).
I think I know what "exit" does, because my pid goes away when I call it, when I call "cancel", lsof shows just my main ssh session and the rest of the port forwards disappear. But the same thing appears to happen if I call "exit" or "stop". So what is the difference between those?
