As for the Windows computers that need an external ethernet adaptor, I took a powershell script the FOG team made and added some lines to lookup the HP computer by serial and update the primary MAC to the HP MAC instead of the adaptor to avoid the “computer already exists” problems. When this is working, I leave the computer on the same adaptor until it’s all imaged and joined to my AD domain before moving the adaptor to another computer to start another image, at which point the script should have fixed the MAC address in the FOG database.

I believe you have to install the FOG powershell API in the base image, and then have this powershell script run after sysprep. I use the Setupcomplete.cmd method by putting a cmd file in %WINDIR%\Setup\Scripts. On an HP, I make sure and have the MAC Address Manager app installed and the service is running before the API script runs.

NOTE I have not used this method since FOG 1.5.6. I’m trying to get my servers updated with 1.5.10.

Setupcomplete.cmd:

Start "Starting HP Services" /wait /separate /realtime CMD /C c:\windows\system32\sysprep\services.cmd Start "Updating MAC Address" /wait /separate /realtime CMD /C powershell -executionpolicy bypass -file c:\windows\system32\sysprep\macupdate.ps1 exit

services.cmd

for /F "tokens=3 delims=: " %%H in ('sc query "HPMAMSrv" ^| findstr " STATE"') do ( if /I "%%H" NEQ "RUNNING" ( net start "HPMAMSrv" timeout /nobreak 3 ) )

Can be set in the function as a default or passed to the function .PARAMETER fogUserToken a string of your fog user token gotten from the fog web ui in the user section. Can be set in the function as a default or passed to the function .PARAMETER fogServer The hostname or ip address of your fogserver, defaults to the default fog-server .PARAMETER uriPath Put in the path of the apicall that would follow http://fog-server/fog/ i.e. 'host/1234' would access the host with an id of 1234 .PARAMETER Method Defaults to 'Get' can also be .PARAMETER jsonData The jsondata string for including data in the body of a request .EXAMPLE #if you had the api tokens set as default values and wanted to get all hosts and info you could run this, assuming your fogserver is accessible on http://fog-server Invoke-FogApi; .Example #if your fogserver was named rawr and you wanted to put rename host 123 to meow Invoke-FogApi -fogServer "rawr" -uriPath "host/123" -Method "Put" -jsonData "{ `"name`": meow }"; .Link https://news.fogproject.org/simplified-api-documentation/ .NOTES The online version of this help takes you to the fog project api help page #> [CmdletBinding()] param ( #took out my api tokens, you can default apitoken strings here or pass them to the function [string]$fogApiToken = 'token...', [string]$fogUserToken = 'token...', [string]$fogServer = "x.x.x.x", [string]$uriPath = "host", #default to get all hosts [string]$Method = "Get", [string]$jsonData #default to empty ) begin { # Create headers Write-Verbose "Building Headers..."; $headers = @{}; $headers.Add('fog-api-token', $fogApiToken); $headers.Add('fog-user-token', $fogUserToken); # Set the baseUri Write-Verbose "Building api call URI..."; $baseUri = "http://$fogServer/fog"; $uri = "$baseUri/$uriPath"; } process { Write-Verbose "$Method`ing $jsonData to/from $uri"; if ($Method -eq "Get") { #don't include body with get $result = Invoke-RestMethod -Uri $uri -Method $Method -Headers $headers -ContentType "application/json"; } else { $result = Invoke-RestMethod -Uri $uri -Method $Method -Headers $headers -Body $jsonData -ContentType "application/json"; } } end { Write-Verbose "finished api call"; return $result; } } # Get MAC addresses of local ethernet adapters, should return only the live (plugged into switch and lit) ethernet MAC. # Will fail if no live adapters found or more than one found.
