I think I have determined why my system keeps having two internet connections at boot-up: /etc/resolv.conf has two nameservers. When I delete one and re-boot, lo and behold, the second is back.
The question, then, is this: What is writing to resolv.conf that makes it have two nameservers? Perhaps rp-pppoe.so? I found where this is, but I do not know how to edit the file. Is this the problem? If so, how do I edit it? Much appreciated and a thank you in advance. -- —A watched bread-crumb never boils. —My hover-craft is full of eels. —[...]and that's the he and the she of it.
