Note

The FreeBSD terminal version of telnet(1) client (in comparison to those available on Linux distributions, like Debian) automatically passes the user login name to the destination server during the authentication process. This is due to the -a parameter, which is enabled by default and is responsible for passing the login name so that the user doesn’t have to input it while loggin in. In order to disable automatic passing of the login name, use -K parameter or -l parameter with empty login.

It’s recommended to pay attention to the default settings of your Telnet client.
