If you don’t like using telnet, that’s fine. Don’t use it. There are plenty of other options available. Use netcat. Or use netcat. Or use netcat. Or read and write directly to /dev/tcp/hostname/port using shell constructs. Or run openssl s_client if you suspect something complicated is listening on the other end. There is more than one way to do it and ways that are not your way still work.

Reminder, there are many different netcats, here are some of the most commons: – netcat-traditional http://www.stearns.org/nc/ – netcat-openbsd : https://github.com/openbsd/src/blob/master/usr.bin/nc/netcat.c (also packaged in Debian) – ncat https://nmap.org/ncat/ – netcat GNU: https://netcat.sourceforge.net/ (quite rare) To prevent any confusion, I like to recommend socat: http://www.dest-unreach.org/socat/.

The original one is the “TCP/IP Swiss army knife” released in 1995: https://nc110.sourceforge.io/ (original release: https://seclists.org/bugtraq/1995/Oct/28) Although it is “freely given away to the Internet community” with “an obligation to give credit where due”, at least OpenBSD and GNU have seen the need to write their own versions under their project licenses: GNU netcat: http://netcat.sourceforge.net/…

From the command line, one could string together netcat and sox and just play a sound when anyone connected to a specific port.
