Tor is a great sysadmin tool (2020)
In many ways I think this blog post really makes quite compelling arguments and honestly opened my eyes a bit.<p>One (perhaps mad) idea for more secure access to a machine deep behind many levels of NAT where you, the sysadmin, have lawful access but are fed up with having to have a 12 KB ~/.ssh/config file in order to access it because of your university's overbearing IT department^W^W^W^W network topology, would be to "just" run an onionsite with onion services authentication [1], preventing it being publicly accessed without the pre-shared key. If your onion service just redirects to ssh (presumably with certificate-only auth) I can't help but think that this is <i>almost</i> an example of security by obscurity done right.<p>[1] <a href="https://support.torproject.org/en-US/onionservices/client-auth/" rel="nofollow">https://support.torproject.org/en-US/onionservices/client-au...</a>
