My topic was "Lost DNS Lookup" Yesterday afternoon I ran tshark and discovered that the dns lookups were going to an old dns server that was no longer in existence. I had poked the correct entries in resolve.conf, only to discover that they were being overwritten by some process. I was finally able to set resolve.conf the way I wanted it, remove the write bit, set the immutable bit, and get it to work. My next task was to go looking at the logs to see what was trying to scribble in resolve.conf...but your post puts me onto something. Since I have a static address approach on my internal network, maybe I need to disable NetworkManager.
