Examples of org.apache.sshd.server.ForwardingFilter.canListen()

org.apache.sshd.server.ForwardingFilter.canListen()

Determine if the session may listen for inbound connections.

This server process will open a new listen socket on the address given by the client (usually 127.0.0.1 but may be any address). Any inbound connections to this socket will be tunneled over the session to the client, which the client will then forward the connection to another host on the client's side of the network. @param address address the client has requested this server listenfor inbound connections on, and relay them through the client. @param session session requesting permission to listen for connections. @return true if the socket is permitted; false if it must be denied.
