is it possible that you try to bind the SSH proxy tunnels to the same
port on localhost? By design of TCP/IP this is not possible. If you
use several session profiles in PyHoca-GUI that are configured to use
the SSH proxy feature then who have to make sure that they do not try
to bind the local tunnel endpoint to the same IP port on localhost.
However, if your PyHoca-GUI wants to use the same IP port for several
profiles you will encounter two problems:
(1) in theory: simultaneous sessions will not be possible
(2) you will receive an SSH host key error before connect
We have to implement a mechanism in PyHoca-GUI that checks this and
warns about duplicate port usage on local SSH proxy tunnel endpoints.
If unsure, please attach those parts of your sessions file that
describe the sshproxy parameters.
