PowerShell - Port Scanner, one port, from text list of Computers/Servers

---

foreach($line in [System.IO.File]::ReadLines("C:\TEMP\TESTING2OU.txt"))

{

$servers=$line

#$Why=Read-Host "Enter Port Number to Check from C:\Temp\Testing2ou.txt List of Computers"

# Define the port number you need to test (eg: 3389 for RDP):

$portToCheck = '445'

foreach ($server in $servers) {

If ( Test-Connection $server -Count 1 -Quiet) {

try {

$null = New-Object System.Net.Sockets.TCPClient -ArgumentList $server,$portToCheck

$props = @{

Server = $server

PortOpen = 'Yes'

}

}

catch {

$props = @{

Server = $server

PortOpen = 'No'

}

}

}

Else {

$props = @{

Server = $server

PortOpen = 'Server did not respond to ping'

}

}

New-Object PsObject -Property $props

}

}

This, similar to the previous port scanner, only this one scans many machines one port, the other scans many ports one machine, ironically it isnt as easy as thought to combine these, thus I have both.
