# 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:
|
|
```bash
|
|
ssh -p10011 -NL 7000:localhost:8080 emiliko@localhost &
|
|
ssh -NL <client-port>:<url-from-host>:<host-port> <user>@<host-address> &
|
|
```
|
|
|
|
# In config file
|
|
The syntax in the config is quite similar
|
|
|
|
```ssh
|
|
LocalForward 8001 localhost:7000
|
|
LocalForward <client-port> <host-address>:<host-port>
|
|
```
