On a related note it's always annoyed me when people use "telnet" when they mean "make a TCP connection" as in "can you telnet to the port?"

- username42 13y agoWhen providing support, you have to be very precise when you ask someone to perform a check. The sentence "can you telnet to the port" is unambiguous. The sentence "can you make a TCP connection" leaves the choice of the tool unspecified. Depending of their background, some people may use ping (subject to different firewall rules), or a browser (subject to proxy configuration).
- icebraining 13y agoPing doesn't make TCP connections!
- username42 13y agoI know, but for many people, pinging the remote host is their single idea for network issue analyse.
- pbhjpbhj 13y agoWhen I'm testing a mail server I'll sometimes use telnet to connect (eg to port 110), or openssl for testing secured connections. What should I be using; or is it just the nomenclature you're bothered about?
- djeikyb 13y agoOne thing I like about the original and the gnu netcat is the z option: `nc -z host port; echo $?` for quick testing.
