public boolean canForwardAgent(Session session)
ForwardingFilter
Determine if the session may arrange for agent forwarding.
This server process will open a new listen socket locally and export
the address in the SshAgent.SSH_AUTHSOCKET_ENV_NAME
environment
variable.

ForwardingFilter
Determine if the session may arrange for X11 forwarding.
This server process will open a new listen socket locally and export the address in the environment so X11 clients can be tunneled to the user's X11 display server.

session

ForwardingFilter
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.

ForwardingFilter
Determine if the session may create an outbound connection.
This server process will connect to another server listening on the address specified by the client. Usually this is to another port on the same host (127.0.0.1) but may be to any other system this server can reach on the server's side of the network.
