The in.telnetd program is a server which supports the DARPA telnet interactive communication protocol.

krb5-telnetd

Secure telnet server supporting MIT Kerberos

Kerberos is a system for authenticating users and services on a network. Kerberos is a trusted third-party service. That means that there is a third party (the Kerberos server) that is trusted by all the entities on the network (users and services, usually called "principals"). This is the MIT reference implementation of Kerberos V5. This package contains a replacement for telnetd that uses Kerberos for authentication.

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.
