Re: [JSch-users] Timing issue with Remote Port Forwards causing 10 second delay

   |I have found a timing issue with reverse port forwarding 
   |(session.setPortForwardingR). This is affecting my application when it 
   |is running on the same physical box as the SSH server. My application 
   |sets up a series of remote forwards, and I noticed that calls to 
   |session.setPortForwardingR() take a very long time (exactly 10 seconds 
   |to be precise). This is because the reply from the SSH server is being 
   |received before the sending thread is ready (sleeping). So, the thread 
   |interrupt never occurs, and the sending thread sleeps for the full 10 
   |seconds.
   |I have resolved the issue by replacing the sleep/interrupt logic with a 
   |simple synchronized reply lock. I have attached the patch diffs to 
   |0.1.43 below.

Thank you for your feedback.
I'll check it out.


Sincerely,
