Check if specific port is open via script?

[adevezin]

Is there a way to check if a port is open via a script? I just want to check if a custom port i have on my network is open via a workflow script.

Port scanning is the first step in the Discovery process. In this stage, Discovery scans the configured IP addresses for TCP and UDP IP ports to determine what ports are open or responsive. When scanning IP Ranges, Discovery searches for responses from WMI, SSH and SNMP protocols. Port scanning results are found in the input package of the Shazzam probe in the ECC Queue

Hi Adrian,

You could use a powershell workflow activity and use the port scanner script below for example:

Script Test-Port
