  • Connect to a remote server:
    ssh username@remote_host
  • Connect to a remote server with a specific identity (private key):
    ssh -i path/to/key_file username@remote_host
  • Connect to a remote server using a specific port:
    ssh username@remote_host -p 2222
  • Run a command on a remote server with a [t]ty allocation allowing interaction with the remote command:
    ssh username@remote_host -t command command_arguments
  • SSH tunneling: Dynamic port forwarding (SOCKS proxy on `localhost:1080`):
    ssh -D 1080 username@remote_host
  • SSH tunneling: Forward a specific port (`localhost:9999` to `example.org:80`) along with disabling pseudo-[T]ty allocation and executio[N] of remote commands:
    ssh -L 9999:example.org:80 -N -T username@remote_host
  • SSH jumping: Connect through a jumphost to a remote server (Multiple jump hops may be specified separated by comma characters):
    ssh -J username@jump_host username@remote_host
  • Agent forwarding: Forward the authentication information to the remote machine (see `man ssh_config` for available options):
    ssh -A username@remote_host
