telnetd - 0.17-41.2 main

The in.telnetd program is a server which supports the DARPA telnet interactive
communication protocol.
.
This legacy server should in general be abandoned in favour of a contemporary
ssh-server, as this implementation only is able to process password and user
name in clear text. Other variants, like telnetd-ssl and a selection of
Kerberized TELNET servers, are able to improve on this by providing secure
forms of authentication and encryption.
