To test my TCP/IP libraries I created a bunch of programs mimicking the Unix commands with the same name. Some of these tools were really useful and another simple hacks to test the protocols.
The included programs were:
- myip (show the client IP)
- nanotel (simple telnet)
- nanoweb (simple web server)
- pop (pop client)
- rshd (rshd server)
- systime (clock synchronizer, for my 386/40 that delayed an hour per day).
The source code included here can be compiled using Turbo C (with KIP (TCP/IP Stack) Library), DJGPP (with KipDJ (KIP for DJGPP)), WIN32 (with the lccwin32 compiler) and Unix (tested under Linux and SunOS 4).
