### Port Binding
Bind local port 8001 to target-server port 80 using jump-machine.local.
_(local machine without direct access to target-server)_
```bash
ssh -f -N -L localhost:8001:target-server:80 usr@jump-machine.local
```
#### Documentation
``` bash
# man
-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.
-N Do not execute a remote command. This is useful for just
forwarding ports. Refer to the description of
SessionType in ssh_config(5) for details.
-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.
