Dear Michal, There doesn't seem to be any timeout, as the telnet session just ends abruptly. Both in CentOS 4.4 and Windows 2000 whenever I'm doing it with a latency of 350ms. But, when I'm trying from the same machine (Windows Server 2003) or from a machine with less than 1 ms latency (CentOS 4.4), it works just fine. It is probably a buffer overrun. I can check it from here, but could you advise how to take a tcp dump? I've used Network Monitor on Windows 2000 before. But, never did it on linux. Can you suggest me some other alternative?
