Everyone, It is apparent that the epel version of denyhosts on Centos 7 which is denyhosts-2.9-4.el7.noarch does not resynch with : SYNC_SERVER = http://xmlrpc.denyhosts.net:9911 According to : https://www.centos.org/forums/viewtopic.php?f=51&t=56989 the problem is related to a version update problem in the epel repositories. I submitted a bugzilla report : https://bugzilla.redhat.com/show_bug.cgi?id=1502251 Greg Ennis
