Everyone, Apparently, aeskulap is broken during the upgrade fro 7.5 to 7.6, and is no longer available in the epel repos. I had some difficulty having it function, and during the debug process I decided to do a yum remove, but when I tried a yum install to reinstall it, aeskulap was no longer present. This problem may also affect other modules. I have placed a bug report : https://bugzilla.redhat.com/show_bug.cgi?id=1659667 The depracation of tcp wrappers may be involved in this https://fedoraproject.org/wiki/Changes/Deprecate_TCP_wrappers -- Greg Ennis
