NOTE: This applies to both open source and commercial editions of Chocolatey.

1. Ensure you are set for organizational deployment

Please see the organizational deployment guide

  • Open Source or Commercial:
    • Proxy Repository - Create a proxy nuget repository on Nexus, Artifactory Pro, or a proxy Chocolatey repository on ProGet. Point your upstream to https://chocolatey.org/api/v2. Packages cache on first access automatically. Make sure your choco clients are using your proxy repository as a source and NOT the default community repository. See source command for more information.
    • You can also just download the package and push it to a repository Download

3. Enter your internal repository url

(this should look similar to https://chocolatey.org/api/v2)

4. Choose your deployment method:


choco upgrade chmac -y --source="'STEP 3 URL'" [other options]

See options you can pass to upgrade.

See best practices for scripting.

Add this to a PowerShell script or use a Batch script with tools and in places where you are calling directly to Chocolatey. If you are integrating, keep in mind enhanced exit codes.

If you do use a PowerShell script, use the following to ensure bad exit codes are shown as failures:


choco upgrade chmac -y --source="'STEP 3 URL'"
$exitCode = $LASTEXITCODE

Write-Verbose "Exit code was $exitCode"
$validExitCodes = @(0, 1605, 1614, 1641, 3010)
if ($validExitCodes -contains $exitCode) {
  Exit 0
}

Exit $exitCode

Description

Named after getmac and chmod, chmac is a command-line-interface (CLI) tool for Windows that changes or randomizes MAC addresses of specified network adapters, e.g. for a client device to reuse public Wi-Fi hotspot that has exceeded usage limit for the day (e.g. hotels, restaurants), or to enhance security.

An easy-to-use interactive console is available, alongside command-line parameters.

List of Features

  • Change MAC addresses on Windows manually or automatically on set intervals
  • Randomize MAC addresses for better security using public Wi-Fi
    • Generate new MAC addresses randomly based on a customizable list of organizationally unique identifiers (OUI)
  • Optionally leverage DevCon.exe to simply the process by automatically disabling and re-enabling network interface card (NIC)
    • ChMac also works without DevCon by showing the Network Connections folder when finished, so that users can manually disable and re-enable NIC for new settings to take effect
    • On first launch, users are guided to download DevCon with convenient automatic and manual options
  • Restore original MAC address
  • Rich return codes for scripting and other possibilities
  • Free and open-source software written in Windows batch language
  • Supports Windows 2000/XP/Vista/7/8/8.1/10 and Server 2000/2003/2008/2012/2016/2019
  • Portable by default. Optional installer enables chmac command globally

Getting Started

For interactive mode, simply run chmac.bat and follow on-screen instructions.

For command-line mode, refer to the below examples.

chmac.bat [/d dir][/l][/m address][/n id][/r][/help][/?]

chmac /l                     :: list available adapter IDs
chmac /n 1                   :: update network adapter #1 with randomized mac address numbers
chmac /m 00301812AB01 /n 2   :: update network adapter #2 with the new mac address: 00-30-18-12-AB-01
chmac /n 3 /r                :: restore adapter 3 to its original MAC
chmac /n 4 /a 20m            :: auto-change MAC per 20 minute
chmac /?                     :: shows short help. [/help] for long
