Thanks for the response, but I am trying to avoid the confusion of having some hosts set in a hostgroup definition and others by just using the hostgroup line in the host definition. If I setup some hosts on the members line in a hostgroup definition and then some with the hostgroup line in the host definition, it populates properly, but I think that will be messy and confusing in the long run. I will cc the devel list and see if anyone can tell me if I can avoid having hostgroup definitions. -Zac <div>On 12/23/05, Hugo van der Kooij <<a href="mailto:hvdkooij@vanderkooij.org">hvdkooij@vanderkooij.org</a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> On Fri, 23 Dec 2005, Zac wrote: > Am I allow to do this?

Besides that it is a user mailinglist and I guess the real developers are on other lists. Hugo. -- I hate duplicates.
