Is it possible for different user accounts on the same computer to have different network settings?
It seems like most network settings are system-wide (written to /etc/*). Is there a way around this?
My goal is to have one user using OpenDNS, while the other users connect without OpenDNS.
That is, for one user, network settings -> IPv4 -> 2 DNS addresses are set and Automatic is off,
whereas for the other users, no DNS address is set and Automatic is on.
No. Networking is a system-wide thing, not a per-user thing.
