SSH config example

ssh_config

# Example ~/.ssh/config

# Connect using ``ssh sandbox`` or ``scp sandbox:* .``
Host sandbox 
    HostName sandbox.local
    User myusername
    IdentityFile ~/.ssh/id_rsa
    Port 22
    ServerAliveInternal 30
    ProxyJump jumphost.local

    # If using local forward, do ssh -f -N host
    # -f puts ssh in background
    # -N makes it not execute a remote command
    LocalForward 9906 127.0.0.1:3306

    # Another local forward example.
    # This one will take the service that sits on the remote host
    # listening locally on port 3006 and makes it available
    # via a local listener that listens on localhost:9999.
    # E.g. Make a remote database that only listens locally available
    #      on your localhost port 9999
    LocalForward 127.0.0.1:9999 127.0.0.1:3306

    # Remote forward will make something available on the local 
    # machine/network available to the remote server.
    # E.g. Making an internal git server available to the host you are
    #   connecting to that would not normally be able to reach the git
    #   server. This eample makes git available on the remote server's port 9999 while on
    #   the remote SSH server
    # In the SSHD config set GatewayPorts to yes to allow public access
    RemoteForward 9999 locally-accessible-address:22

    # Set up a SOCKS proxy on 127.0.0.1:9999 that lets you pivot through the remote host(HostName) 
    # Then configure the local tool/browser to use a SOCKS proxy of localhost:9999
    DynamicForward 127.0.0.1:9999
