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?
What is the difference between exit and stop in ssh multiplexing commands?
