@kistel maintains #Netiscope. Not to be confused with Netskope. 😁
https://github.com/robert-kisteleki/netiscope
It's a small #OpenSource tool for checking network connectivity from the #CLI or through an optional local #GUI. It runs checks for local interfaces, #DNS resolvers, open resolvers, root DNS servers, port filtering, #DoH, #SSH host keys and #IPv6 path MTU.
