I am trying to setup Ruby CI workers using Fedora's Jenkins instance [1, 2]. Unfortunately, the Rinda/DRb tests typically timeouts [3] with failures such as:

Apparently, this is because the Jenkins builder have all ports except 22 and 80 blocked. The fix is to use localhost by default for tests of Rinda/DRb. I submitted the PR [4] fixing this issue. I'd appreciate if it can be merged. It would enable CI for latest Fedoras and possibly RHEL.
