psp (PowerShell Ping)

How to ping computers to test for network connectivity.

If you only need to ping a single machine with Test-Connection then using the -quiet parameter will return a True/False value that can be used as part of a simple If statement:

If (Test-Connection remotehost -count 1 -quiet) {
 Write 'The host responded'
 # Add other statements here..

The function below may be used two ways: pipe one, or a whole list of machines to psp, or alternatively type psp remotehost on the command line. Examples below. The function is named psp rather than ping because you may still wish to run ping.exe from the PowerShell command prompt.

Function psp {
   param($InputObject = $null)

   BEGIN {$status = $True}

      if ($InputObject -and $_) {
         throw 'ParameterBinderStrings\AmbiguousParameterSet'
      } elseif ($InputObject -or $_) {
         $processObject = $(if ($InputObject) {$InputObject} else {$_})

         write-host "Ping [$processObject]"

         if( (Test-Connection $processObject -Quiet -count 1)) {
            write-host "Ping response OK" -ForegroundColor DarkGreen
         else {
            write-host "Ping failed - host not found" -ForegroundColor red
            $status = $False
      else {throw 'ParameterBinderStrings\InputObjectNotBound'}

    # next processObject

    # Return True if pings to all machines succeed:
    END {return $status}

This function will return a True or False value, $True will only be returned if the pings to ALL the machines succeed.

Note: PowerShell does not save functions or aliases permanently by default. So if you close and reopen PowerShell, this function will no longer be available. To make it permanent, add the function to your PowerShell $Profile file.

An alternative, to ping a number of hosts in parallel rather than sequentially, use the WMI class Win32_PingStatus

Get-WmiObject -Class Win32_PingStatus -Filter 'Address="" and Timeout=2000 or Address="" and Timeout=2000' | Select-Object -Property Address, ProtocolAddress, ResponseTime, Timeout


Ping server64:
PS C:\> psp server64

Ping three servers:
PS C:\> "server64" ,"server65" , "" | psp

Ping a list of workstations:
PS C:\> $workstations = cat E:\MachineNames.txt
PS C:\> $workstations | psp

or using foreach:
PS C:\> foreach($workstation in $workstations){psp $workstation}

Perform a command only if the machine server64 responds to a ping:

if (psp "server64"){
   echo "responding"
   } else {
   echo "machine not found"

“And now I see with eye serene
The very pulse of the machine” ~ William Wordsworth, (She Was a Phantom of Delight)
