      When running scratch-build for target: c9s-candidate related to this PR <https://gitlab.com/redhat/centos-stream/rpms/ruby/-/merge_requests/18>, I saw that DNS is enabled in s390x servers.

      $ centpkg --release c9s scratch-build --srpm --nowait
      

      Here is the CentOS stream koji link.
      https://kojihub.stream.rdu2.redhat.com/koji/taskinfo?taskID=2412513

      Host is "s390-04.stream.rdu2.redhat.com" seeing the s390x build task below.

      I tried to check the DNS connection using the following patch on the PR above.

      $ git diff
      diff --git a/ruby.spec b/ruby.spec
      index 012cdcb..6d1de40 100644

      But the build was succeeded. The used s390x host is "s390-03.stream.rdu2.redhat.com".
      https://kojihub.stream.rdu2.redhat.com/koji/taskinfo?taskID=2412559

      So, I assumed that DNS servers are enabled in some s390x build servers. Could you take a look to disable the DNS on the servers?

      As a note, the unit tests in the ruby spec file access to the following domains.

      rubygems.org
      www.rubygems.org
      staging.rubygems.org
      index.rubygems.org
      

      I remember we faced this issue in another brew servers. So, I hope a systematic approach not to repeat this kind of issue again in the future.
      Thank you.
