PortCheck 2.1 for Windows 10
PortCheck is a tiny, portable command line tool for administrators, network and firewall admins. You can check if a remote device answers on a certain TCP port. Short overview:
PortCheck runs on Windows 7 / 8 / 10 / 11 (32 or 64 bit). It requires .NET Framework 3.5
PortCheck returns ERRORLEVEL 0 or 1 in dependence of the result. ERRORLEVEL is 1 if the port answers, and 0 if there is no response. You can use this value in your own batch files.
PortCheck is free - also for professional use. Please read the licensing information.
Interactive mode with -i: You can create a shortcut on the desktop that asks for host and port when double-clicked. Very practical for ad hoc checks.
Individual text: Texts can be completely customized. An interesting feature. For example, in the event of an error, instead of the "networker language" this text could appear: "No answer from Production-Machine1. Please call 5678". Furthermore, the output can be adapted to any language.
Alerting in case of error: PortCheck can now execute batch files in case of closed ports and in the "repaired case". Also only after several failures - completely configurable.
Bugfix: PortCheck 2.0 sometimes showed a wrong result when own Windows firewall was blocking an outgoing port.
You can download PortCheck here as a zip file. It contains 4 files.
