How can I append a nameserver in /etc/resove.conf?
not a named qurstion at all, however becasue something overwrote /etc/resolv.conf after your script which maybe means your script runs way too early chattr +i /etc/resove.conf under normal conditions chattr -i /etc/resove.conf at the start of your script chattr +i /etc/resove.conf at the end of your script https://www.tecmint.com/chattr-command-examples/ this is a supported way to prevent resolv.conf overwritten by whatever stuff running on the system, be it dhclient, networkmanager or another smartass stuff which lives in a authistic world pretend to know what my nameservers are _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
