Invoke-IPv4PortScan

Powerful asynchronus IPv4 Port Scanner.

• view function

Description

This powerful asynchronus IPv4 Port Scanner allows you to scan every Port-Range you want (500 to 2600 would work). Only TCP-Ports are scanned.

The result will contain the Port number, Protocol, Service name, Description and the Status.

To reach the best possible performance, this script uses a RunspacePool. As you can see in the following screenshot, the individual tasks are distributed across all cpu cores:

Syntax

Invoke-IPv4PortScan [-ComputerName] <String> [[-StartPort] <Int32>] [[-EndPort] <Int32>] [[-Threads] <Int32>] [[-Force]] [[-UpdateList]] [<CommonParameters>]

Example 1

PS> Invoke-IPv4PortScan -ComputerName fritz.box -StartPort 1 -EndPort 500

Port Protocol ServiceName ServiceDescription               Status
---- -------- ----------- ------------------               ------
  21 tcp      ftp         File Transfer Protocol [Control] Open
  53 tcp      domain      Domain Name Server               Open
  80 tcp      http        World Wide Web HTTP              Open

Example 2

PS> Invoke-IPv4PortScan -ComputerName TEST-PC-01 -StartPort 1 -EndPort 500
PS> TEST-PC-01 is not reachable!
PS> Would you like to continue? (perhaps only ICMP is blocked) [yes|no]: yes

Port Protocol ServiceName ServiceDescription               Status
