Puppet agent service is not starting

edit

I am trying to make puppet agent run in the background and periodically check my puppet master for changes.

I kwon that I could use linux cron job to achieve this. But I think that using puppet service is better for my case. I just couldn't find any error log to start with.

root@puppettest:/# service puppet status
 * agent is not running
root@puppettest:/# service puppet start 
 * Starting puppet agent                                                 [ OK ]
root@puppettest:/# service puppet status
 * agent is not running

Here is my configuration:

root@puppettest:/# cat /etc/lsb-release
