Still Love Telnet
> "For the purposes of logging into a remote server, you should never, and probably have never considered it."This is not true when the client and server have both implemented Wireguard.With Wireguard in place, it is safe to return to legacy telnet, ftp, and rsh. The use of rcp still remains problematic, for the same reasons that scp is deprecated.It is not best practice to return and rely on these legacy protocols, as they are bad habits and are vulnerable when Wireguard (or equivalent protections at a lower level in the network stack) are in place.
