Here lives Kerberos

Here you can get Kerberos Telnet for Windows 95, 98 and NT.

KTELNET gives you the following functionality:

* Telnet client with kerberos authentication and encryption.
* FTP client with kerberos authentication.
* Proxy server that will allow you to use your favourite mail reader and still use kerberos authentication.
* KTELNET will be able to run through a NAT type firewall and a firewall supporting HTTP proxy with 'CONNECT' (but not other types of firewalls).

If you find anything that you suspect is a bug in KTELNET, please don't heasitate to send me a mail describing the problem and I will try to pinpont the problem.
