    # -D [bind_address:]port
    #    Specifies a local "dynamic" application-level port forwarding.  This works by allocating a socket to listen to port on the local side, optionally bound
    #    to the specified bind_address.  Whenever a connection is made to this port, the connection is forwarded over the secure channel, and the application
    #    protocol is then used to determine where to connect to from the remote machine.  Currently the SOCKS4 and SOCKS5 protocols are supported, and ssh will
    #    act as a SOCKS server.  Only root can forward privileged ports.  Dynamic port forwardings can also be specified in the configuration file.
	#
	# Note: -D mode only do a port fowarding on local side, i.e. works only on telnet localhost port, rather than telnet PUBLIC_IP port
	#       Therefore we have to do a public port fowarding e.g. 
	#			step 1. kent@hostname   $ ssh -R 7321:rd1-2:22 ubuntu@amazon-ec2.no-ip.org -o TCPKeepAlive=no -o ServerAliveInterval=60 
	#       	step 2. ubuntu@hostname $ ssh -D 8888 localhost -p7321 -lkent -vvv -N
	#       	step 3. ubuntu@hostname $ socat TCP-LISTEN:12345,fork TCP:localhost:8888
	#           step 4. Setup browser proxy settings as "SOCK v5" + "amazon-ec2.no-ip.org:12345"
