[Puppet Users] puppet not working after switch to passenger - permissions issue?
Hi, as suggested on the list I switched from the standalone puppetmaster to Passenger. I have passenger installed now and edited the apache config as far as I understood. I restarted apache. Now when I run an agent I get: /var/lib/gems/1.8/bin/puppet agent --server node002 --test err: Could not retrieve catalog from remote server: Error 403 on SERVER: Forbidden request: node039(192.168.73.39) access to /catalog/node039 [find] at line 0 warning: Not using cache on failed catalog err: Could not retrieve catalog; skipping run In the server log I find this: May 4 14:13:08 node002 puppet-master[14489]: Denying access: Forbidden request: node039(192.168.73.39) access to /catalog/node039 [find] at line 0 May 4 14:13:08 node002 puppet-master[14489]: Forbidden request: node039(192.168.73.39) access to /catalog/node039 [find] at line 0 Here is my apache config: ======== # you probably want to tune these settings PassengerHighPerformance on PassengerMaxPoolSize 12 PassengerPoolIdleTime 1500 PassengerMaxRequests 1000 PassengerStatThrottleRate 120 RackAutoDetect Off RailsAutoDetect Off Listen 8140 <VirtualHost *:8140> SSLEngine on SSLProtocol -ALL +SSLv3 +TLSv1 SSLCipherSuite ALL:!ADH:RC4+RSA:+HIGH:+MEDIUM:-LOW:-SSLv2:-EXP SSLCertificateFile /etc/puppet/ssl/certs/node002.pem SSLCertificateKeyFile /etc/puppet/ssl/private_keys/node002.pem SSLCertificateChainFile /etc/puppet/ssl/ca/ca_crt.pem SSLCACertificateFile /etc/puppet/ssl/ca/ca_crt.pem # If Apache complains about invalid signatures on the CRL, you can try disabling # CRL checking by commenting the next line, but this is not recommended.

Re: [Puppet Users] puppet not working after switch to passenger - permissions issue?
Ok, seems that I have an authentication issue here. when I set (for all paths) "auth no" in auth.conf, it''s working again. Maybe I set these options wrong in the apache.conf: SSLCertificateFile /etc/puppet/ssl/certs/node002.pem SSLCertificateKeyFile /etc/puppet/ssl/private_keys/node002.pem As far as I can tell these files match. regards, Andreas Andreas Kuntzagk wrote:> Hi, > > Nan Liu wrote: >> On Wed, May 4, 2011 at 8:26 AM, Andreas Kuntzagk >> <andreas.kuntzagk@mdc-berlin.de> wrote: >>> Hi, >>> >>> as suggested on the list I switched from the standalone puppetmaster to >>> Passenger.

I''m not 100% sure if that''s correct but I''m running 2.6.8 on mine and that appears to be one of the magic bits needed. Also in your apache config, add # The following client headers allow the same configuration to work with Pound. RequestHeader set X-SSL-Subject %{SSL_CLIENT_S_DN}e RequestHeader set X-Client-DN %{SSL_CLIENT_S_DN}e RequestHeader set X-Client-Verify %{SSL_CLIENT_VERIFY}e That seems to be the other bit that actually passes the authentication down the chain to puppet. -Paul -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
