Ssh connect through another host

The issue

I wanted to connect to a host through another host. And I wanted it as simple as possible to use.

The solution

Make sure sshd and netcat (nc) ist installed and set up on your server. (sshd on both, nc only on the "proxy")

Then add this to your .ssh/config:

Host noc noc.mathpeter.net

    Hostname [TARGETHOST]
    User [USERONTARGETHOST]
    ProxyCommand ssh [PROXY-HOST-CAN-ALSO-BE-CONFIGURED-IN-.ssh/config] exec nc %h %p
