SSH port forwarding

Local port forwarding allows ssh to connect one of your ports to the destination's port. This is particularly useful for localhosted websites, which you can run on the host and access on your machine

Some key terms:

<client-port> = Port on the machine you're using to ssh. Ex: laptop
<host-port>   = Port on the machine running sshd
<host-address> = URL of machine running the sshd, which you're logging onto
<url-from-host> = Name relative to the host machine who's port the host forwards

The opens an ssh tunnel without obstructing the current terminal:

    ssh -NL 8001:localhost:7000 emiliko@cs.ox.ac.uk &
    ssh -NL <client-port>:<url-from-host>:<host-port> <user>@<host-address> &

In config file

The syntax in the ~/.ssh/config is quite similar

Host mirrorside
    User emiliko
    Hostname cs.ox.ac.uk
    LocalForward 8001 localhost:7000

The general format looks like

    LocalForward <client-port> <host-address>:<host-port>
