This week’s BSD Now talks about some recent security discussions with telnet and (unrelateD) OpenSSH history, and points to a recent discussion on DragonFly I haven’t even gotten to link yet, cause it’s ongoing.
(telnet is awful but it makes me feel nostalgic, cause of all the times I typed ‘GET HTTP/1.0 /’ into it.)
It’s also fun sending emails via telnet
It’s useful to test TCP servers.
