[JSch-users] Getting information on local port forwarding progress

[Peter H. <pet...@gm...>]

At the moment it seems JSch isn't very verbose as to what happens AFTER the
ssh connection is established. You can configure a logger but it will only
give you information on the phase up until the SSH connection is
established. Nothing more.

Consider the following local port forwarding scenario:

myworkstation --> jumphost --> desthost


I would like to see the following logged:

1. When myworkstation receives a tcp connection it should log that this is
happening, i.e in the Socket.accept().
Something like:
"Received connection on myworkstation:lport from 10.1.2.3"

2. Following the above JSch should log what it is now attempting to do.
Something like:
"Instructing SSH server at jumphost to establish connection to
desthost:rport"

3. The result of the previous can be either success or failure.
In case of success, JSch should log something like:
"Connection successfully established from jumphost to desthost:rport. Local
port forwarding is now active"
In case of failure something like:
"jumphost cannot establish connection to desthost:rport"


Is this somehow possible or do I need to file a feature request?
