SSH Jump

With ssh jump, we can ssh into a machine that we don’t have direct access to through an intermediary.

Just chain the necessary hosts together with the following command:

ssh -J host1 host2 host3 ...

Where the last host is the one you wish to connect to at the end.

Luckily ssh config also supports this!

Host host1

Host host2
  ProxyJump host1
