[Puppet Users] Error: Could not request certificate: Connection refused - connect(2)
Hi ... my head hurts! Sorry this is a bit long, but I hope it has all the
relevant evidence.
I am getting this error on my agent host:
err: /Stage[main]/Testfiles/File[/tmp/test1]/content: change from
{md5}d41d8cd98f00b204e9800998ecf8427e to
{md5}6be3210bf77dea7c998e13ba69e5f06e failed: Could not back up /tmp/test1:
Server hostname ''ncqd-isghub01'' did not match server
certificate; expected
one of ncqd-isghub01.nott.ime.reuters.com,
DNS:ncqd-isghub01.nott.ime.reuters.com, DNS:puppet,
DNS:puppet.nott.ime.reuters.com
This is the hosts file entry on the agent:
10.6.176.21 ncqd-isghub01.nott.ime.reuters.com ncqd-isghub01 puppet
I did have certificates for the master (ncqd-isghub01) but following
instructions provided by others for addressing them, I removed them:
[root@ncqd-isghub01 ssl]# puppet cert clean
ncqd-isghub01.nott.ime.reuters.com
Notice: Revoked certificate with serial 5
Notice: Removing file Puppet::SSL::Certificate

[root@ncqd-isghub01 ssl]#
At this point I realised that on the master host I had the wrong IP
address for itself (it has recently been relocated), so I corrected that
and for safety''s sake cleaned out /var/lib/puppet/ssl. I then did the
following:

Now why would it be unable to verify the certificate it’s just signed?
I then tried using my normal test agent, expecting the certificate request
to be generated anew, as I’d blitzed it earlier:
*Master as agent:*
[root@ncqd-isghub01 ssl]# puppet cert list --all
+ "ncqd-isghub01.nott.ime.reuters.com" (SHA256)

[11674](root@ntm-igdev02)/etc/puppet:
So as far as the real agent is concerned, I''m back where I started and
the
questions I have are:
1. Why is a new certificate request not generated? I still only have the
one for the master.
2. Why doesn''t the master recognise its own certificate?
3. What is the problem with the normal agent''s complaint about the
master''s
certificate?
Any assistance would be gratefully received! Thanks.
