Hmm, could you pleas help me with that?

1) in line 207 I added --encryption="1" like that (this is one line):

								sendString("startsession --encryption=\"1\" 
--session=\""+m_sessionName+"\" "


2) I'm not sure how to change "Instead of connect=m_sshData.host do add 
accept=127.0.0.1."

3) I'm not sure how to change "Then do not disconnect the m_SSH Process 
in line 265, but instead send"

4) "Spawn and connect a netcat to the proxy port and connect the stdout 
of this process to the stdin of the ssh process and vice versa." - does 
this mean I have to do this tricks with netcat etc. each time? or is it 
perhaps one time only to see if it works?
