    PingMon

    PingMon

    Ping monitoring tool (32 Bit) for any Windows System (x86 or x64)

    This is a ping monitoring tool for almost any Windows System (tested on Win 98*-10 and Server 2003-2016) and it runs on Linux via WINE either*. No .NET is needed. This is a 32bit app and will work on x86 and x64 architectures. Adjustable and easy to use. And you can choose if you want it to create RAW packets instead of using Windows icmp.dll resources. Usage examples: PingMon.exe HOST1 HOST2 Will open 2 instances of PingMon and start pinging immediately. Since Windows shortcuts are limited, there also is a way to run a batch file like this: start PingMon.exe HOST 1 start PingMon.exe HOST 2 ... start PingMon.exe HOST 33 The numbers are used for positioning. Version 0.3 and later contain another tool, PingHist, to visualize log files again: PingHist.exe LOGFILE Will visualize file LOGFILE. *) Versions 0.2 and higher don't run on non-NT systems. This is due to elevation detections. So, on Windows 98 you will have to run 0.1 versions No further dev.
