SSH - Secure Shell

Forward a port from a remote source (I.E. a VPS) to specific port on localhost

ssh -L 65432:localhost:80 user@111.222.333.444 -p 54321 -i .ssh/id_rsa_selected_key

Command breakdown ssh No explanation needed (?)

-L 65432:localhost:80 The forwarding part of the command. 65432 is the port you want to forward to on the target/receiver/local device. localhost:80 is the port om the remote.

user@111.222.333.444 -p 54321 The remote's user, IP-address and SSH port (if port is not specifiec in remote's settings, defaults to 22)

-i .ssh/id_rsa_selected_key '-i' is used when a specific SSH key is needed

Creating a key

ssh-keygen -t rsa -C "some.identifier@name.com"
