I’ve been running Ubuntu as my laptop operating system for quite some time (year or more) and find it to be quite wonderful. However, recently I had some nasty times getting everything to work with OpenDNS.
The easy thing to do is change /etc/resolv.conf to contain the OpenDNS entries. However, this was complicated by my use of polipo (web cache), pdnsd (DNS cache), and resolvconf (a resolv.conf file manager) – not to mention the use of ddclient to update the dynamic IP on the laptop, and the Gnome NetworkManager.
