Still Love Telnet
> "For the purposes of logging into a remote server, you should never, and probably have never considered it."<p>This is not true when the client and server have both implemented Wireguard.<p>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.<p>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.
