The problem is on this line in ipautil.CheckedIPAddress with the netmask=ifdata['netmask'] call
ifnet = netaddr.IPNetwork('{addr}/{netmask}'.format( addr=ifaddr, netmask=ifdata['netmask'] )) On my CentOS 7.3 box which has python-netifaces-0.10.4-3.el7.x86_64 it works On my CentOS 7.4 box where I am trying to install ipa-server-4.5.0-22.el7.centos.x86_64 and it has python2-netifaces-0.10.5-2.el7_4.x86_64 installed, it fails with: ValueError: IPAddress() does not support netmasks or subnet prefixes! See documentation for details. So I don't see how anyone has been able to install ipa-server on a RedHat 7.4 or CentOS 7.4 box Might be related to this: https://bitbucket.org/al45tair/netifaces/issues/50/netmask-format-of-ipv6-address-is-not _______________________________________________ FreeIPA-users mailing list -- freeipa-users@lists.fedorahosted.org To unsubscribe send an email to freeipa-users-le...@lists.fedorahosted.org
