Hi Alice man NetworkManager.conf in /etc/NetworkManager/NetworkManager.conf .... dns=none .... suomi On 04/11/2017 10:40 AM, Alice Wonder wrote:
Hello list - http://unix.stackexchange.com/questions/90035/how-to-set-dns-resolver-in-fedora-using-network-manager That says it works for CentOS 5 and I *suspect* the methods there (3 listed) would work, but what is the best way with NetworkManager to set it up to use the localhost for DNS ? I'm paranoid about DNS spoofing and really prefer to have a local instance of DNSSEC enforcing unbound running on my CentOS 7 virtual machines (e.g. linode) Currently I just use a cron job that runs once a minute to over-write was it is /etc/resolv.conf so they don't use the DHCP assigned nameservers, but that does leave a short window every time the network is restarted. I'd like to know the proper way to set up Network Manager to just create nameserver 127.0.0.1 nameserver ::1 in /etc/resolv.conf Via google, it seems every distro approaches it differently and most instructions I have seen involve a GUI. I did not see how to do it in the CentOS documentation but it might be there and I just did not figure out how to search it for what I wanted. Those stackexchange methods look like they might work but they reference CentOS 5 and I know some NetworkManager stuff changed even just between 7.2 and 7.3 as I experienced incorrect IPv6 address after update as a result of those changes. Is there an "official" way to tell NetworkManager what I want in /etc/resolv.conf ? Or better yet, a way to just tell it to leave that file alone? _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx https://lists.centos.org/mailman/listinfo/centos
