Problem:
After a successful installation of foreman in the logs I get the following errors everyday around 03:00AM:

I have a installation whit the following setup:

  • Server1 = Foreman , Foreman-proxy;
  • Server2 = Puppet Master;
  • Servevr3 = RemoteDB

Foreman-proxy settings.yml:

:ssl_ca_file: /etc/puppetlabs/puppet/ssl/certs/ca.pem
:ssl_certificate: /etc/puppetlabs/puppet/ssl/certs/pkpsdc24.telecom.pt.pem
:ssl_private_key: /etc/puppetlabs/puppet/ssl/private_keys/pkpsdc24.telecom.pt.pem

Files:

[root@pkpsdc24 foreman-proxy]# ll /etc/puppetlabs/puppet/ssl/certs/
total 8
-rw-r–r--+ 1 puppet puppet 1968 Aug 5 12:03 ca.pem
-rw-r–r--+ 1 puppet puppet 1968 Aug 5 12:03 pkpsdc24.telecom.pt.pem
[root@pkpsdc24 foreman-proxy]# ll /etc/puppetlabs/puppet/ssl/private_keys/
total 4
-rw-r-----+ 1 puppet puppet 3243 Aug 5 11:58 pkpsdc24.telecom.pt.pem

The user foreman and foreman-proxy bellong to the group puppet.

Expected outcome:
No errors being reported.

Foreman and Proxy versions:
foreman-1.21.3-1.el7.noarch
foreman-proxy-1.21.3-1.el7.noarch
puppet-agent-5.5.16-1.el7.x86_64

Anyone khows how can I overome this errors or what do they mean ?

#2

UPDATE:

  • Tried the proposed solution in the Bug #14719, were it is suggested to comment the following lines in the foreman-proxy lib/launcher.rb file:

#ssl_options |= OpenSSL::SSL::OP_NO_SSLv2 if defined?(OpenSSL::SSL::OP_NO_SSLv2)
#ssl_options |= OpenSSL::SSL::OP_NO_SSLv3 if defined?(OpenSSL::SSL::OP_NO_SSLv3)
#ssl_options |= OpenSSL::SSL::OP_NO_TLSv1 if defined?(OpenSSL::SSL::OP_NO_TLSv1)

But to no avail. Yesterday the same errors appeared:

Is there any other information that I can give to help better understand this problem ?

#3

It looks like some process is scanning your smart-proxy. Foreman doesn’t use OPTIONS and it’s also sending other garbage. Is there some internal security scanner that tries to find weaknesses?

#4

Thanks for Feedback.

This cluster is inside a huge organization, is very likely that that is the case but I will never have 100% guarantee.

I just wanted to see if someone new if this was a fixable problem or not a problem at all.

Is there anything I can do to make foreman ignore those errors and\or not showing them ?

#5

Given that line you can firewall 10.144.167.5. I’m very certain this is something that tries to scan it for weaknesses. That can be a legitimate instance (many large orgs have such a thing) or an actual intruder. I’d contact your internal networking and/or security teams on how to proceed.
