1. Describe your incident:
I’m Having a problem sending logs from my firewall to the graylog server. I’m running a fortigate on 7.x code and following this link GitHub - seanthegeek/graylog-fortigate-cef: A Graylog content pack containing a stream and dashboards for Fortinet Fortigate CEF logs

When checking the logs under /var/log/graylog-server/server.log, Im seeing the connection error:

2022-09-21T19:31:17.161-04:00 WARN [AbstractTcpTransport] Client auth configured, but no authorized certificates / certificate authorities configured for input [CEF TCP/63271fa5c677c11cc45447b6]
2022-09-21T19:31:17.225-04:00 ERROR [AbstractTcpTransport] Error in Input [CEF TCP/63271fa5c677c11cc45447b6]

2. Describe your environment:

  • OS Information:
    Graylog server: Ubuntu server 20.04
    Firewall: 7.2.0

  • Package Version:
    Graylog 4.3

  • Service logs, configurations, and environment variables:

3. What steps have you already taken to try and solve the problem? I have been googling around on how to create the cert and locations but are only finding old items from 2016/2018/2020 on graylog 3.x

4. How can the community help?
If you can point me into an guide, that would be great. any help would be great.

Thank you in advance,

Hello,

I see your using CEF TCP as a input by chance do you have TLS enabled?

Does these FortiGate firewalls have Certificates on them? If not try using CEF UDP instead see if that works or disable the tic box for enabling TLS.

As for creating the certificates TCP/TLS if there from the firewall I would make sure Graylog can read them and there installed in GL’s keystore with the right format.

THank you for the help. I was thinking of trying UDP. That did the trick. I’m getting all the great log data now.

Once more thank you for the help.
