Yep, SSHD is already binding to port 22 on all interfaces.  Which means...

 Sn> mystic config
 Sn> whoops sorry left that out, it port 22

Mystic can't use port 22 at the same time.

You'll need to change one of the two.  Mystic can be changed in its own
configuration program.

SSHD's configuration can be changed via the sshd_config command, though it may
not bring up your text editor of choice.  You can also edit
/etc/ssh/sshd_config yourself, then restart SSHD.  Either way, change the
"Port" directive to something else.

If you don't have a console set up on this Pi then I would leave SSHD alone and
move Mystic.  If you break SSHD you can effectively brick the installation.

If it was my machine, I would simply move Mystic to port 2222.  If the machine
is behind a router you'll need to set the router up for port forwarding anyway.
 It's just as easy to forward to port 2222 as it is 22.
