What is the CentOS mailing list?

In order for JetPatch to properly patch CentOS machines, the JetPatch server must be able to connect to the following mailing lists

• For CentOS 7 -  https://lists.centos.org/pipermail/centos-announce/
• For CentOS 8 - https://cefs.steve-meier.de/

If a proxy needs to be configured, see this article

To test, log into the JetPatch server and run the following command (example for CentOS7):

curl -kv https://lists.centos.org/pipermail/centos-announce/

In order to verify that individual endpoints are properly configured, please run the following command

yum updateinfo
