I am not running the network manager so it may be different for you. Here I use the prepend domain-name-servers XXXXXXXXXXXX in /etc/dhcp3/dhcpclient.conf. More information in man dhcpclint.conf <div class="gmail_quote">On Jan 20, 2008 6:42 PM, <<a href="mailto:sukadev@us.ibm.com">sukadev@us.ibm.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Hi, I just migrated to Ubuntu Gutsy from Fedora Core 6. I used DHCP on FC6 and am continuing to do so on Ubuntu. On FC6, I used to add any additional domains to /etc/resolv.conf 'search' line and set set PEERDNS=no in the ifcfg-eth0 line. This would preserve my additional domains across network restarts. I am not sure how to do the same on Ubuntu. I searched a bit in the documentation and could not find anything specific. I saw something about running "Network Manager", but when I try to run Network Manager from my kubuntu desktop it does not let me edit the settings possibly bc I am not root. I click on the "Admin mode' button at the bottom of the screen. It prompts me for password and then goes back to the same state. i.e I still cannot edit the network settings.
