Solution

ssh — Secure Shell is a protocol used to securely log onto remote systems. It can be used for logging or executing commands on a remote server. More information: <https://man.openbsd.org/ssh>.

Connect to a remote server:

ssh {{username}}@{{remote_host}}

Connect to a remote server with a specific [i]dentity (private key):

ssh -i {{path/to/key_file}} {{username}}@{{remote_host}}

Connect to a remote server with IP 10.0.0.1 and using a specific [p]ort (Note: 10.0.0.1 can be shortened to 10.1):

ssh {{username}}@10.0.0.1 -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: [D]ynamic 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 [J]umping: 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}}

Close a hanged session:

<Enter><~><.>
