VNC server ---- FW (ssh server ) ------ INET ----- Client
na clientu ssh -L Nejaky_port:IP_VNC_serveru:port_VNC_serveru IP_Firewallu
Jinak man ssh
-L port:host:hostport
Specifies that the given port on the local (client) host is
to be
forwarded to the given host and port on the remote side. This
works by allocating a socket to listen to port on the local
side,
and whenever a connection is made to this port, the
connection is
forwarded over the secure channel, and a connection is made to
host port hostport from the remote machine. Port
forwardings can
also be specified in the configuration file. Only root can
for-
ward privileged ports. IPv6 addresses can be specified with an
alternative syntax: port/host/hostport
Vsimete si: and a connection is made to host port hostport FROM THE
REMOTE MACHINE !
