To ease the analysis of connection problems when working with multiple sessions/ports/log files it would be handy if there was a little more information given in one log line. This is especially necessary when grepping over multiple log files.

When starting a session the output is currently:
Listening for connections at <local address>

But should be something like:
Listening for connections at <local address> for sessions [<list of sessions>]

When there is an unknown session id encountered during logon, the output is currently:
Unknown session ID during logon: <session ID>

But to quickly identify the session which is concerned, the following output is better:
Unknown session ID during logon: <session ID> connecting from <remote address> to <local address> cannot be found in session list: [<list of sessions>]
