Custom Windows Fact (match ipaddress)

[cko]

Hi everybody,

I'm trying to write a custom fact that gets the IP Address of any given NIC if it matches a specific IP range.

On Linux i use this (works fine)

Facter.add("ip_foo") do
   setcode do
      Facter::Util::Resolution.exec("/sbin/ifconfig | /bin/grep '192.168.20[567].' | /bin/awk '{ print $2 }' | /bin/cut -d':' -f2")
   end
end

Now my Windows Version:

Facter.add("ip_foo_windows") do
   confine :operatingsystem => :windows
   setcode do
      Facter::Util::Resolution.exec("C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe ipconfig | Select-String -pattern '192.168.20[567]' | %{$_.line.split()} | FINDSTR 192.168.20[567]")
      end
end


When i run the command C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe ipconfig | Select-String -pattern '192.168.20[567]' | %{$_.line.split()} | FINDSTR 192.168.20[567] on the box it works perfectly fine. It returns the value that i need.

But it seems that puppet doesn't get that value into the fact.

Since you've double quoted the string you need to escape the backslashes, eg "C:\\Windows\\...

Still no effect.

   Facter::Util::Resolution.exec("C:\\Windows\\System32\\WindowsPowerShell\\v1.0\\powershell.exe ipconfig | Select-String -pattern '192.168.20[567]' | %{$_.line.split()} | FINDSTR 192.168.20[567]")

Is there anything else i need to escape?

The second issue is that findstr is a shell builtin, so you have wrap the entire command in:

cmd.exe /c <original command>

You may have to quote the original command and adjust the interior quotes accordingly.

I still can't get it to work:


 Facter::Util::Resolution.exec("C:\\Windows\\System32\\cmd.exe /c 'C:\\Windows\\System32\\WindowsPowerShell\\v1.0\\powershell.exe ipconfig | Select-String -pattern '192.168.20[567]' | %{$_.line.split()} | FINDSTR 192.168.20[567]'")

hi all,

try using the sysnative instead of System32

The File System Redirector will silently redirect all file system access to%windir%\system32 to %windir%\SysWOW64 instead. This can be an issue when trying to manage files in the system directory, e.g., IIS configuration files. In order to prevent redirection, you can use the sysnative alias, e.g.C:\Windows\sysnative\inetsrv\config\application Host.config.
