Local port forwarding

Command explanation

To forward port of remote host use the following command

ssh -L <LOCAL_PORT>:<TUNNEL_IP>:<DESTINATION_PORT> <user>@<server_ip>

-L stands for local adress because we are tunneling connection on local machine, TUNNEL_IP is 127.0.0.1

ssh -L <LOCAL_PORT>:127.0.0.1:<DESTINATION_PORT> <user>@<server_ip>

Real life example

• I have a server with ip 69.69.69.69
• I have user on a server called gnumik
• My public key is recognized by this server and I can establish ssh connection like this:

ssh gnumik@69.69.69.69

• I have postgresql data base running on the server on port 5432
• I want to have access to this postgre instance from my local machine using local port 5433
• I need to execute the following command on my local machine:

ssh -L 5433:127.0.0.1:5432 gnumik@69.69.69.69

P.S. I use arch btw
