Hello list –
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
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?
