Due to a screw up, I have to regenerate client & server certificates.

As far as I know, the master certificates are automatically generated.

So I generated keys on the client:

MASTER # puppet cert clean --all
Notice: Revoked certificate with serial 2
Notice: Revoked certificate with serial 6
Notice: Removing file Puppet::SSL::Certificate puppet.x.com at '/var/lib/puppet/ssl/ca/signed/puppet.x.com.pem'
Notice: Removing file Puppet::SSL::Certificate puppet.x.com at '/var/lib/puppet/ssl/certs/puppet.x.com.pem'
Notice: Removing file Puppet::SSL::Key puppet.x.com at '/var/lib/puppet/ssl/private_keys/puppet.x.com.pem'
Notice: Removing file Puppet::SSL::Certificate efikamx-9ba3ab.x.com at '/var/lib/puppet/ssl/ca/signed/efikamx-9ba3ab.x.com.pem'
Notice: Removing file Puppet::SSL::Certificate efikamx-9ba3ab.x.com at '/var/lib/puppet/ssl/certs/efikamx-9ba3ab.x.com.pem'

puppet agent --no-daemonize  --onetime --verbose --waitforcert 60 
notice: Did not receive certificate

CLIENT # puppet agent -t

Before you ask, yes, ntp is running and both clients have the correct time.

What's the correct way to purge all the certificates on both ends and correctly regenerate everything?

I've ran:

find /var/lib/puppet -type f -print0 |xargs -0r rm

and

rm -rf /var/lib/puppet/ssl/*

on the client, but that did not help.

This is a mixture of Puppet 2 and Puppet 3 by the way.

  • When you say mixture of puppet 2 & 3, which one is v3? The docs strongly suggest that the puppetmaster should always be newer than any clients. – Zoredache Jul 8 '13 at 23:12
  • The master is version 3.1.1; the clients are either 2.7.x or 3.x (right now, I'm testing with two 2.7 clients) – Tuinslak Jul 8 '13 at 23:13

Apparently the problem lied in the fact that Apache was still running (and thus having a puppet master spawned via Passenger).

MASTER /etc/apache2/sites-enabled # /etc/init.d/apache2 stop
[ ok ] Stopping web server: apache2 ... waiting .
MASTER /etc/apache2/sites-enabled # puppet cert clean --all
Notice: Revoked certificate with serial 2
Notice: Removing file Puppet::SSL::Certificate puppet.x at '/var/lib/puppet/ssl/ca/signed/puppet.x.pem'
Notice: Removing file Puppet::SSL::Certificate puppet.x at '/var/lib/puppet/ssl/certs/puppet.x.pem'
Notice: Removing file Puppet::SSL::Key puppet.x at '/var/lib/puppet/ssl/private_keys/puppet.x.pem'

Notice: Removing file Puppet::SSL::CertificateRequest efikamx-561a37.x at '/var/lib/puppet/ssl/ca/requests/efikamx-561a37.x.pem'

And now I can correctly generate and sign the keys on the client:

CLIENT ~ # rm -rf /var/lib/puppet/ssl/*
CLIENT ~ # puppet agent -t
info: Creating a new SSL key for efikamx-9ba3ab.x.com
info: Caching certificate for ca
info: Creating a new SSL certificate request for efikamx-9ba3ab.x.com
info: Certificate Request fingerprint (md5): 8C:9E:6E:95:B8:70:B9:A2:98:CB:A5:87:BC:66:33:A4
Exiting; no certificate found and waitforcert is disabled
CLIENT ~ # puppet agent --no-daemonize  --onetime --verbose --waitforcert 60
info: Caching certificate for efikamx-9ba3ab.x.com
