The Linux kernel accepts certain 'command-line options' or 'boot time parameters' at the moment it is started. In general this is used to supply the kernel with information about hardware parameters that the kernel would not be able to determine on its own, or to avoid/override the values that the kernel would otherwise detect.

-L localhostport:remotehost:remoteport

Specifies that the given localhostport on the local (client) host is
to be forwarded to the given remotehost and remoteport on the remote side.
This works by allocating a socket to listen to localhostport on the local
side, optionally bound to the specified bind_address. Whenever a con-
