Using puppet to set Windows Computer Description
Posted by Admin • Monday, May 18. 2020 • Category: DevOpsMy company's security department decided to assign Antivirus exclusion policies based on the value of the windows computer description. That means that I need to set computer descriptions ( net config server /srvcomment:"new description" ) to the same value on a whole bunch of windows machines. Doing that by hand is unappealing, and I already have puppet, so here is a simple solution:
MYCLASS/lib/facter/wincomputer_description.rb
# Gets computer decscription from 'net config server'
Facter.add("win_computer_description") do
setcode do
output = `net config server`
output.split(/\n/).find{|it| it.start_with?('Server Comment') }.gsub(/Server Comment[\s]*/,'')
end
end
MY_CLASS/manifests/init.pp
class MY_CLASS(
$computer_description = 'Some-new-description',
) {
if ($win_computer_description != $computer_description) {
exec { 'Set computer description':
path => ["C:\\windows\\system32"],
command => "net config server /SRVCOMMENT:\"${computer_description}\"",
}
}
}
