Constant values that describe channel type.
When type = LocalListen then 'port
forwarding' is initiated between wodSSHTunnel and the
SSH server. (wodSSHTunnel listens to local sockets and
forwards requests to the SSH server)
When type = RemoteListen then 'remote port
forwarding' is initiated between the SSH server and
wodSSHTunnel. (the SSH server listens to its sockets and forwards
requests to wodSSHTunnel)
When type = SocksProxy then wodSSHTunnel dynamically opens ports
and allows virtually any host/port to be connected. Unlike the static
tunnels defined with LocalListen and RemoteListen values, this
setting forwards connections as requested by the application. The only
requirement is that the applications can support SOCKS4(a)/SOCKS5
proxy servers.
