-L [bind_address:]port:host:hostport
-L [bind_address:]port:remote_socket
-L local_socket:host:hostport
-L local_socket:remote_socket
Specifies that connections to the given TCP port or Unix socket on the local
(client) host are to be forwarded to the given host and port, or Unix
socket, on the remote side. This works by allocating a socket to listen to
either a TCP port on the local side, optionally bound to the specified
bind_address, or to a Unix socket. Whenever a connection is made to the
local port or socket, the connection is forwarded over the secure channel,
and a connection is made to either host port hostport, or the Unix socket
remote_socket, from the remote machine.
Port forwardings can also be specified in the configuration file. Only the
superuser can forward privileged ports. IPv6 addresses can be specified by
enclosing the address in square brackets.
By default, the local port is bound in accordance with the GatewayPorts
setting. However, an explicit bind_address may be used to bind the
connection to a specific address. The bind_address of “localhost” indicates
that the listening port be bound for local use only, while an empty address
or ‘*’ indicates that the port should be available from all interfaces.
-f
Requests ssh to go to background just before command execution. This is
useful if ssh is going to ask for passwords or passphrases, but the user
wants it in the background. This implies -n. The recommended way to start
X11 programs at a remote site is with something like ssh -f host xterm.
If the ExitOnForwardFailure configuration option is set to “yes”, then a
client started with -f will wait for all remote port forwards to be
successfully established before placing itself in the background.
-N
Do not execute a remote command. This is useful for just forwarding ports.

如果我理解你是正确的,你可以从你到达笔记本电脑的地方打电话给ssh . 然后你应该能够做这样的事情:
这将创建在主机上启动tcp侦听端口,其中ssh始发,通过您运行的计算机转发到远程主机和端口 .
