Check For Open Port with If then statement

PowerShell Help
1

Hi Forum. I need help putting code together. I’m trying to check a specific local tcp port is open (in this case port 3306). if it’s closed i’d like to open it.

query:
If the port is open, echo “port is open…”
else, if port is closed, open port.
end.

this seems like a pretty straightforward code yet, i’m stumped…

I would suggest you to look into some cmdlets that will let you interact with the Firewall. Like Get-NetFirewallRule and Get-NetFirewallPortFilter. Try to see what you can get back with it, and try to use it to do your check.

btw: if you would have used Get-Command getfirewall, you would have found a lot of firewall related cmdlets.

Could something like this work to find out if a port is open and listening?

Get-NetTCPConnection -LocalPort 80
