I’m somewhat of a linux newbie so please be kind. I’m having intermittent DNS resolution issues while connected to my company VPN. After running nslookup in debug mode it looks like the system is using DNS out of rotation. (sometimes it uses the company’s DNS, other times it randomly defaults to my ISPs). The search paths are also being used out of rotation (rather than from first to last).
- I am not using dnsmasq
- I do not have options rotate set in resolv.conf.
- Not using anything weird like “Round robin”.
- nsswitch.conf hosts is set to “files dns”.
- /etc/NetworkManager/NetworkManager.conf doesn’t have anything set for dns or rc-manager
I ran “watch cat /etc/resolv.conf” to see if any other process or software was overriding my resolv.conf, but that doesn’t appear to be the case. Not sure what else to check or what else could be causing issues.
