alt Hacker News> IMHO we need a good telnet replacement that sends signed data. Most people interpret signatures as allowed under FCC rules, just not encryption.
I know from bitter experience that IPsec is a “now you have two problems” kind of solution, but the Authentication Header is a thing and is supported by most (all?) implementations. Ham radio operators probably don’t have much use for the actual features of telnet compared to plain netcat, do they? (It’s mostly terminal feature negotiation and such.)
TIL that IPsec can be used without encryption. That should work pretty well.
Telnet is mostly used for auth and straightforward terminal/BBS access in my experience. There are some other alternatives like HamSSH but I don’t think it’s that common.
