SSH

Local Port Forwarding

Open a tunnel from the client to a server. AKA trying to point your web browser at a private web server.

Format:

ssh -L <local_port>:<remote_addr>:<remote_port> <server>

If you want to access something on the remote server itself, use localhost as the remote_addr

Examples

Port forward a postgres database running on the remote:

ssh -L 5432:localhost:5432 myuser@myserver

Access a private database from an admin host:

ssh -L 5432:database.rds.amazonaws.com:5432 myuser@admin-host
