Scanning internal ports - Iperf alternative

Hi,

Is there such an application that can scan ports between two devices so see there which ports are open/closed/listening?

We have two devices, each one on different sides of wireless link, on the same network, and we wish to confirm there is no issue of ports not working.

The type of app I am think is iperf but for ports.

Thanks,
Col

Did you try NETSTAT command in Windows CMD window ?

You could use Angry IP Scanner or Advanced IP Scanner. There are a lot of programs that could be used for this.

Netstat would help you see if a machine is listening on a port or if something is connected to a port, but won't help you if a software firewall is blocking that port. Tools that scan from other machines will let you know if the port is open from a firewall aspect and if the system is listening or a particular port.
