RE: SSH reverse tunnel

[lars van ruiten <larsvanruiten@xxxxxxxxxxx>]

Hi,
I'm not sure, but that does not seem like the right way to do it. The program will run on the pc's with the shipview servers, so I imagined this:
1. connect() to the middleman server2. request that the middlemen server listens to port 5907 with  ssh_channel_listen_forward()3. Create channel to localhost:5900 with ssh_channel_accept_forward()4. ???
Please tell me if this is the correct way to do this.
Kind regards,Lars van Ruiten
