Failed To Create An Incoming Tunnel

This error indicates that the system has not been able to create the requested tunnel.

The most common reason for this failure is that a tunnel with the same name already exists. The similarly named tunnel may have been created by another client connected to the same server.

If the system has several Secure Shell users, they may already have reserved several available ports. In this case just try again to find a free port.

Another possible reason is that you have no permission to open the requested port. The system administrator may have set a policy that restricts opening of communications ports - this is common practice especially with incoming ports. Check the local policy from the system administrator. Please note that only the system administrator (root) can open port numbers under 1024.

Please note that both incoming and outgoing tunnels produce their own error messages. If both fail, the client will display two separate error messages.
