Wireshark puts your network card into promiscuous mode so that your computer picks up all network packets, not just those intended for your computer. It can be installed on Windows, Linux, Unix, and Mac OS, and best of all, it’s free. Optional: If you're running Windows 10 / Server 2012 R2 / Server 2016 and want to use those Toast Messages that popup in the lower right-hand corner right above the time, just change the 'Target' field in the shortcut to the following:Ĭ:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -NoProfile -NoLogo -Command "& C:\Users\\Downloads\Enable-PromiscuousMode.Wireshark is a very popular packet sniffer. Now you can double-click Enable-PromiscuousMode.ps1 - Shortcut to enable PromiscuousMode for the specified Network Interface (it will prompt you for the name) This will make double-clicking the shortcut launch the script with elevated permissions (as opposed to needing to right-click the shortcut and select 'Run As Administrator') Still under the 'Shortcut' tab, click the 'Advanced' button, and check the checkbox that says 'Run as Administrator'. Under the 'Shortcut' tab, in the 'Target' field, paste something like the following (change the path to the script to match where you placed it)Ĭ:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -NoProfile -NoLogo -Command "& C:\Users\\Downloads\Enable-PromiscuousMode.ps1" Right-Click on Enable-PromiscuousMode.ps1 - Shortcut and select 'Properties' Right-Click on Enable-PromiscuousMode.ps1 and select 'Create shortcut' In the above, that would be your Downloads folder. Use the File Explorer GUI to navigate to wherever you downloaded Enable-PromiscuousMode.ps1. Invoke-WebRequest -Uri $EnablePromModeUrl -OutFile "$HOME\Downloads\Enable-PromiscuousMode.ps1" # NOTE: Change -OutFile path if you want it downloaded to a different path ps1 file, you can do the following:ĭownload Enable-PromiscuousMode.ps1 via. If you want to run this via double-clicking a. $Socket.IOControl(::ReceiveAll, $byteIn, $byteOut) # NOTE: You might need to play with this value if things don't work.
$Socket.SetSocketOption("IP", "HeaderIncluded", $true) $Socket = New-Object (::InterNetwork, ::Raw, ::IP)
$(Get-NetAdapter -Name "Ethernet").PromiscuousMode # The below returns 'True' if Promiscuous Mode is already on # Check Promiscuous Mode Status for the Adapter your interested in. Thanks to everyone who commented and offered suggestions. Make sure you run PowerShell as an administrator. Below is the script in case anyone is interested.
FYI - /u/fourierswager helped me and created a PowerShell script that will place the NIC in promiscuous mode.
