The file should be: 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 The second problem may be in whatever created that ifcfg-eno1 file. I have resorted and cleaned it up so it is easier to look at DEVICE=eno1 NAME=eth0 BOOTPROTO=none BROADCAST=192.168.1.255 DNS1=22.214.171.124 DNS2=126.96.36.199 DNS3=127.0.0.1 GATEWAY=192.168.1.1 IPADDR=192.168.1.110 NETMASK=255.255.255.0 NETWORK=192.168.1.0 DEFROUTE=yes DOMAIN=palmettodomains.com IPV4_FAILURE_FATAL=no IPV6INIT=no ONBOOT=yes TYPE=Ethernet UUID=cfd35a8f-6c40-4a80-bff5-821a91d0775b ZONE=public The third problem is possibly your DNS3 which is pointing to 127.0.0.1 which means you have a local nameserver running on the box. No idea what that is but it is probably something that needs to be reconfigured or turned off. > TIA > > _______________________________________________ > CentOS mailing list > CentOS at centos.org > https://lists.centos.org/mailman/listinfo/centos -- Stephen J Smoogen.
