- 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:
|
|
|
|
`ssh {{remote_host}} {{command -with -flags}}`
|
|
|
|
- SSH tunneling: Dynamic port forwarding (SOCKS proxy on localhost:9999):
|
|
|
|
`ssh -D {{9999}} -C {{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}}`
