I'm looking for a few people to connect to a small 'server' I am running to help me test my TCP/IP for DOS. It can be reached at: telnet 24.159.200.228 2023 It does not do telnet parameter negotiation so echo and line editing are dependent upon your particular telnet client. I've found that the standard telnet client in Win XP does local echoing, Win 2K does not do local echoing, and Linux does local echoing with local line editing. If something doesn't work just try it again without any extra whitespace chars or backspaces. For the sake of traffic on the list, please use discretion when replying to this - obviously stuff of general interest should be posted publicly .. Some background on the project: I've been writing my own TCP/IP for DOS machines since around Nov 2005. Everything except the packet drivers that I am using is new code that I wrote for this project. I was busy with other things the last eight months and I'm finally getting back to working on it. (The last round of testing was in late Dec.) The development machine is a 386-40 using Turbo C++ 3.0 for DOS. The code runs reasonably well on my PCjr. Eventually I want to do a telnet BBS. A Linux box is tracing incoming and outgoing traffic in case I need to debug something that crops up. The test is running on the 386 today because I am doing extensive tracing in the code as well. This particular test code accepts connections from up to 9 clients and lets you play around with some simple commands. The idea is to exercise the TCP/IP code with multiple concurrent connections, so please excuse the simple interface. Thanks! Mike
