Screenshot of nmap running in terminal to enumerate the SSL ciphers on a domain. The domain is my home server, nutmeg.social. nmap shows that TLS version 1.2 is supported. This means any browser or device that supports at least TLS version 1.2 will be able to successfully connect to my mastodon server. Older devices that don't support version 1.2 will prevent software on their device from trying to connect.
It's rare that I need to check TLS version support, but #TIL that #nmap is pretty great at that. #networking
