Multipinger with powershell

  • [アーティクル]

I decided to give this a go and create a multipinger with powershell... this is my first draft!

if I get time I plan to change it to use jobs instead and then format the results out... but this is a functional first draft..

 

here is the code

 

param ([parameter(mandatory=$true)] [string]$begin, [parameter(mandatory=$true)] [string]$end)

function pingip([string]$firstoct,[string]$secondoct,[string]$thirdoct,[string]$fourthoct)
{
  
 $iptotest = $firstoct + "." + $secondoct + "." + $thirdoct + "." + $fourthoct
 $test = test-connection $iptotest
     
 if ($test.count -gt 0)
 {
     $result =  "$iptotest is alive"
 }
 else
 {
  $result =  "$iptotest is dead"
 }
 
    return $result
}

 

$ErrorActionPreference = "SilentlyContinue"

$ipbegin = $begin.split(".")
$ipend = $end.split(".")
$firstoctetmatch = $false
$secondoctetmatch = $false
$thirdoctetmatch = $false
$fourthoctetmatch = $false

if ($ipbegin[0] -eq $ipend[0])
{
 $firstoctetmatch = $true
}

if ($ipbegin[1] -eq $ipend[1])
{
 $secondoctetmatch = $true
}

if ($ipbegin[2] -eq $ipend[2])
{
 $thirdoctetmatch = $true
}

if ($ipbegin[3] -eq $ipend[3])
{
 $fourthoctetmatch = $true
}

if ($firstoctetmatch -eq $true)
{

 write-host "First Octet Matches"
 $firstoctet = $ipbegin[0]

      $startingnumber++

    }
    else
    {
     write-host "Invalid Number Detected in either starting number or ending number"
     write-host "Numbers cannot be 0 or 255"
     exit 1
    }
   }
