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.

netkit-telnet (0.17-40) unstable; urgency=low
* Bring in package changes from experimental to unstable.
* debian/rules: Add a variable LDDEFS. It is consumed during linking
and is intended to suppress unnecessary linking.

netkit-telnet (0.17-39) experimental; urgency=low
* Isolate support for USERVAR in a separate patch for easier use in
the variant package netkit-telnet-ssl.  Add LANG and LC_* to the
list of environment variables acceptable by the server.  Add support
in the client for exporting USERVAR classified variables.
+ debian/patches/120-some_protocol_refinement.diff: Updated.
+ debian/patches/124-support_uservar.diff: New file.

accepts USERVAR classified variables, and the user agent announces
non-standard named variables as USERVAR.  Closes: #237268
+ debian/rules: Add '-DACCEPT_USERVAR' to CFLAGS and to CXXFLAGS. 
* Modify patch for direct use also with package netkit-telnet-ssl.
