SSH tips and tricks.



This linux.com article will make a handy reference for anyone who’s a bit fuzzy on what ssh can do other than just something that looks like telnet, although encrypted from end to end. It’s from their CLI Magic series. Among the topics covered.


Passwordless logins with ssh keys (walks through setting up your key, auth_keys file on the remote host and correct permissions.)

Disabling remote root logins (good way to tighten down your config.)

Executing commands on a remote machine (without launching a shell).

Encrypting remote X through a ssh tunnel… and the big one of them all

Port forwarding with ssh. (Port forwarding can give you a secure point to point encrypted tunnel for any port on the remote machine to a local port.) If you use linux and deal with remote connections you should learn more about ssh.
