ssh¶

ssh is installed by default

basic ssh usage¶

the most *nix-style way of getting help for ssh is man ssh.
I assume that the ssh port is 22 and the involved firewalls are setup accordingly.

ssh user@example.com

ssh usage through another machine¶

What if you can't reach a machine directly but through a machine in between?

Of course you could ssh twice, more compact form is:

ssh -t user@reachable ssh user@unreachable

X-session access¶

ssh -X user@example.com

starting a X-program inside the remote shell will bring up a local X-window.

Port forwarding to local machine¶

the following command will forward port 3390 (e.g. vrpd) on example.com to local 3501.

This is useful when a given port is only accessible local on a remote machine but not accessible from outside.

ssh -L 3501:localhost:3390 user@example.com

now you can connect to the e.g. remote vrdp-session by simply on your local machine.

rdesktop-vrdp -kde localhost:3501

"dynamic tunnel port" for use as socks.proxy¶

sometimes a VPN is kind of an overkill, so if you only need to access local http-ressources from outside and can establish an SSH-connection from outside, this is a nice solution.

ssh -N -D2000 user@example.com

The parameter -N prevents an interactive shell, the parameter -D defines the local port for the dynamic tunnel. This port should be chosen above 1023, so you don't need root-access.
