learning how to do an ssh jump host on tpo

You need to use an ssh jump host to access internal machines at tpo. If you have a recent enough ssh (>= 2016 or so), then you can use the ProxyJump directive. Else, use ProxyCommand. ProxyCommand automatically executes the ssh command on the host to jump to the next host and forward all traffic through.

If your local username is different from your tpo username, also set it in your .ssh/config.

Ex: To perform a ssh jump host and access staticiforme.tpo you might add the following to your /.ssh/config

With recent ssh versions:

Host *.torproject.org
  User <username>
Host staticiforme.torproject.org
  ProxyJump perdulce.torproject.org

Or with old ssh versions:

Host *.torproject.org
  User <username>
Host staticiforme.torproject.org
  ProxyCommand ssh -l %r -W %h:%p perdulce.torproject.org
