puppet.conf on server:

> [main] logdir=/var/log/puppet

i user the default node on site.pp

i am a newer to puppet,so i dont know the reason for these problems!!

thank you again!!!

Solution 1:

Puppet get it's default domain from the domain declaration in /etc/resolv.conf. It takes it from the last domain declaration even if commented out.

Solution 2:

Have you searched for "Puppet" on ServerFault before asking the question?

Please look at:

Puppet: Node name seems dependent on reverse dns?

and see if this might be applicable in your situation?

Otherwise, please describe your configuration.
