About Timeout option for the telnet in windows 2003

Question

Task: On a list of nodes i want to check are those telnet reachable through port 8080 or not with out using name/password from windows 2003 machine.

problem: It is taking to long time for getting out of prompt(some time it seems like hanging).

Thanks in advance. kishore.

Answer 1

That is really to do with the behaviour of the TCP/IP stack rather than that of telnet.exe (or any other high-level application).

Have a look at this article from Microsoft - search it for TcpMaxConnectRetransmissions - and you might be able to cut it down to max 3 seconds per host, but I can't find any way to further reduce that 3 seconds.
