Hi!

Just replace some hardware on my puppet master, new motherboard.

Everything seems to be working just fine, however all my puppets are consistently failing with "sslv3 alert bad certificate".

I have read a lot of threads the simply encourage to delete all certificates and generate new ones. But I have a serious problem with that, I like to understand why things happen. Also, I hate to run things by hand on my nodes, that is why a got Puppet in the first place, this keeps happening from time to time, etc...

So, I am digging deeper to check what is going on.

If I run puppet agent -t, I get the error: SSL_connect returned=1 state=SSLv3 read server session ticket A: sslv3 alert bad certificate.

However, both client and server have the same ca certificate, nothing seems to have changed, by just digging a bit into the files.

I also run by hand the following command from the node:

openssl s_client -connect puppet:8140 -CAFile my-puppet-ca.pem

And I get a nice Verify return code: 0 (OK).

So, the problem does not seem to be the actual certificates, but something "puppety" going on...

any idea what could be going on?

I run puppet 3.8.x on Ubuntu.

I can also verify that the client certificate is correct: has been signed with the puppet ca. Like so: openssl verfiy -CAfile certs/ca.pem -purpose sslclient certs/host.pem I get an OK for the certificate.

ohhh!

The problem is the date of the puppet master.

After the HW change it was off a few months and NTP did not fix it for some reason.

I've seen odd issues with things like that due to some odd NTP misconfiguration
