SSH tunnel: local => gateway => MySQL server

Question

I need to access a MySQL database on a remote server at my lab. The server is only accessible once I log in to a gateway server on the remote network:

local serv         


        

Answer 1

Using the tunnel:

ssh -f user@gateway -L 3307:1.2.3.4:3306 -N 

you will be able to connect to the database on localhost port 3307
