telnetd
basic telnet server
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.
telnetd-ssl
telnet server with SSL encryption support
The in.telnetd program is a server which supports the DARPA telnet interactive communication protocol. SSL telnetd replaces normal telnetd using SSL authentication and encryption. It interoperates with normal telnetd in both directions. It checks if the other side is also talking SSL, if not it falls back to normal telnet protocol. Advantages over normal telnetd: Your passwords and the data you send will not go in cleartext over the line. Nobody can get it with tcpdump or similar tools.
