This software is a WIN32 application that provides an alternate method of integrating winsock applications into the ax25
world. It is a proxy server of sorts, that allows winsock clients to connect, and exchange data with any tcp/ip server, via
any ax25 machine that is 1) reachable through the FlexNet32 interface, and 2) supports some form of raw telnet command.
In simpler terms, KLMProxy allows me to use winsock clients like Netscape Mail or Eudora Mail, to send mail (SMTP) and check
mail (POP3) over a packet radio connection with our local TNOS BBS system. Binary files like pictures, zipfiles, etc, are fully
supported. Just recently added, KLMProxy now let's me use any Telnet client, to 'telnet' to any site reachable from the ax25
This is still a prototype. Services like HTTP, FTP, and others are on my todo list. I have tested KLMProxy on both NT and
Windows 98 platforms with good results. I have used KLMProxy with ax25 machines running Xnet 1.22 and a modified* version
of TNOS 2.30.
* There is a small catch for those using NOS type software. Those systems do not support
a raw telnet option, however you can add that feature to the NOS, with a small software
patch which I have made available in the download section of this website. A binary of
the modified TNOS 2.30 is also included there, for those who are not able to compile
their own version.
