tcping.exe - ping over a tcp connection

Description:

tcping.exe is a small console application that operates similarly to 'ping', however it works over a tcp port. Not a terribly interesting concept, but I had trouble finding a windows utility to do this that I was happy with.

Update: Feb 28 2007. Have added '-t' and '-n <count>' command line options by request.

Update: Jun 22 2009. Have added '-i', '-d', '-b' command line options by request.

Update: Aug 16 2009. Now using QueryPerformanceCounter instead of ftime for timing.

Update: Oct 14 2009. Returning 0 for success, 1 for failure, and 2 for mixed success and failure.

Usage:

Usage: tcping [-t] [-d] [-i interval] [-n times] server-address [server-port]

         -t   : ping continuously until stopped via control-c
         -n 5 : for instance, send 5 pings
         -i 5 : for instance, ping every 5 seconds
         -d   : include date and time on each line
         -b 1 : enable beeps (1 for on-down, 2 for on-up,
                              3 for on-change, 4 for always)

        If you don't pass server-port, it defaults to 80.
