The classic PowerShell example1

The foreigner wrote a more classic PowerShell example

# Functionto Check if $Server is online

Functioncanping ($Server) {

$error. Clear ()

$tmp = test-connection $Server-erroractionsilentlycontinue

if ($?) {

Write-host "Ping succeeded: $Server"; Return $true

}

else {

Write-host "Ping failed: $Server."; Return $false

}

}

# Functionto Check if $Server is remotely accessible

Functioncanremote ($Server) {

$s = new-pssession $Server-authenticationcredssp-credential $Credentials-name "Test"-erroractionsilentlycontinue

if ($s-is[system.management.automation.runspaces.pssession]) {

Enter-pssession-session $s

Exit-pssession

Write-host "Remote Test succeeded: $Server."; Return $true

}

else {

Write-host "Remote test failed: $Server."; Return $false

}

}

# Executefunctions to check $Server

if ($Server-ne "UNC") {

if (canping $Server) {

if (-not (Canremote $Server)) {

Write-host "Exit loop REMOTE"-foregroundcolor Yellow

Continue

}

}

else {

Write-host "Exit loop PING"-foregroundcolor Yellow

Continue # ' Continue ' to the nextobject and don ' t execute the rest of the code, ' break ' exits the foreach loopcompletely

}

}

Improvements :

# Function to check if $Server is remotely accessible

Function Canremote ($Server) {

Try {

$s = new-pssession $Server-authentication credssp-credential $Credentials-name "Test"-erroraction Stop

Write-host "Remote Test succeeded: $Server."

$true

Remove-pssession $s

}

Catch {

"Remote Test failed: $Server."

$false

}

}
