Editor: KpyM Telnet/SSH Server ( KTS ) is free, open source telnet and ssh server for Windows NT/2000/2003/XP/Vista. KTS provides access to the host computer via telnet or ssh protocol. It allows you to run remotely your command line applications (dir, ftp, etc.) and full color console graphic applications (sapconsole.exe, edit.com, tetris.exe, etc.). KTS accepts connection from any telnet/ssh client running on any OS.
When running as SSH server, KTS provides File Transfer and file manipulation via SFTP protocol.
KTS runs as a service and uses the native Windows identification mechanism, thus no additional user names and passwords are stored. Includes an automated install/uninstall program and a console setup. It comes with complete source code distributed under the BSD license.
Ssh support is provided through Peter Gutmann's cryptlib library.
Cryptlib is distributed under a dual license that allows free, open-source use under a GPL-compatible license and closed-source use under a standard commercial license.
