Puppet users - Dec 2011 - Ubuntu 11.10 EC2 Instance : Hostname Mistmatch Issue

Hi All,

I''m trying to configure puppetmaster and puppet clients using Ubuntu
11.10 EC2 Instances (ami-a562a9cc). I have enabled automatic
certificate signing. But whenever I issue command from puppet client :

*#puppet agent --server puppet --waitforcert 60 --test

Certificates get signed but it throws an error and does not run
catalog file.

Error Message :

err: Could not retrieve catalog from remote server: hostname was not
match with the server certificate
warning: Not using cache on failed catalog
err: Could not retrieve catalog; skipping run
err: Could not send report: hostname was not match with the server
certificate

Applying Manifest file on PuppetMaster works out fine but doesn''t work
on puppetclients.

I have already setup puppet environment on Amazon Linux & Centos and
it worked out fine on them. But I''m facing these issues for Ubuntu
11.10

Thanks
Sanket Dangi

The error message is trying to say that the server presented its SSL
certificate to the agent, but the cert''s common name and none of its
subjectAltNames matched the name that the agent tried to connect to, in
this case `puppet`.

This error message has been improved in
http://projects.puppetlabs.com/issues/7224

The troubleshooting section of our docs has more information on how to
resolve this: http://docs.puppetlabs.com/guides/troubleshooting.html
