Function for Powershell to test if TCP port answers
function Test-Port($hostname, $port)
{
# This works no matter in which form we get $host - hostname or ip address
try {
$ip = [System.Net.Dns]::GetHostAddresses($hostname) |
select-object IPAddressToString -expandproperty IPAddressToString
if($ip.GetType().Name -eq "Object[]")
{
#If we have several ip's for that address, let's take first one
$ip = $ip[0]
}
} catch {
Write-Host "Possibly $hostname is wrong hostname or IP"
return
}
$t = New-Object Net.Sockets.TcpClient
# We use Try\Catch to remove exception info from console if we can't connect
try
{
$t.Connect($ip,$port)
} catch {}
if($t.Connected)
{
$t.Close()
$true
}
else
{
$false
}
}
Use hostname as variable in CMD/BAT file
FOR /F "usebackq" %%i IN (`hostname`) DO SET HOST=%%i ECHO %HOST%
