It's data send to the server in a phase called "option negotiation". If you start a telnet on another system (e.g. Linux) to connect to your nc server, you'll see the same. It's triggered by either having no port given or if the port begins with a dash. > explicitly for telnet to connect to port 23, then telnet works fine > (case 2). When using MS telnet, that works fine too (case 3, 4). Hehe, no. MS telnet doesn't send the option negotiaton since it just don't know about it. > Is this a win98SE specific bug, or a telnet bug?
