I have multiple dev environments which are hosted on vCloud. These environments are clones of Prod because of code restriction, i cannot change server name. Meaning, when i clone server1 from production to dev environments it would still be called server1 in those environments.

During puppet training my instructor told me that it was possible to have a server with name A talk to puppetmaster as B by updating puppet.conf . Meaning, when server1 could request catalogue from puppetmaster as serverAAA. I am unable to see hostname option in puppet.conf file. Am i looking at wrong place?

Couple of options you can try

in your puppet.conf

[agent]
certname = someserver.example.com

However you might find it simpler to do it from the command line. I prefer this method as it's easy to pull different catalogs rather than having to edit a config file. Here are a few examples.

sudo puppet agent --certname someserver.example.com --environment stage --noop
sudo FACTER_fqdn=someserver.example.com puppet agent --server puppet.example.com

Remember that running from command line will still use any settings in your puppet.conf that you aren't explicitly setting from the command line.

Do note however that there can be weird side effects to using either approach. --certname or certname= will leave both the $fqdn and $hostname facts at their original values. FACTER_fqdn ...(more)

Thanks for your inputs, i have made some progress, but still have couple of questions. On serverA I updated certname in puppet.conf as certname = serverB and ran puppet agent ...(more)

Both work fine for me. Update your original question with the commands and logs so we can see what you're doing. Also make sure certname = is in the [agent] section.
