Hi! Here is a telnet test using NetCat as server and telnet connecting to localhost. When the telnet uses the default telnet(23) port then as telnet connects some rubbish is sent to the server (case 1). When specifing 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). See attachment for my system details. Is this a win98SE specific bug, or a telnet bug? Thanks, NMarci =========== case 1 =========== Case 1 1. start "nc -l -p 23 -v -v" in a bash window (window #1) 2. start "telnet localhost" in an other bash window (window #2) result: in the window #1 something appears seems to sent by telnet. expected result: only the "connected to [127.0.0.1]" message should appear 3. press Ctrl+C in wondow #1 ----------- window #1 -------- $ nc -l -p 23 -v -v listening on [any] 23 ... connect to [127.0.0.1] from localost [127.0.0.1] 1025 ˇýˇűˇűˇű ˇű!ˇű"ˇű'ˇý sent 0, rcvd 24 ----------- window #2 -------- $ telnet localhost Trying 127.0.0.1...
