Trying to update your nameservers the old fashioned way can be a headache on Ubuntu. There is this thing called resolvconf that likes to change your settings back when you reboot. So for future reference, here’s what I found.<\/p>\n

First of all, as with any normal linux install, nameservers are spelled out in the file “\/etc\/resolv.conf” however this now includes the ominous warning
\n# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
\n# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
\n<\/code><\/p>\n

There is a folder \/etc\/resolvconf\/resolv.conf.d\/ with 3 files; “base”, “head” & “original”. The warning above actually comes from this head file. In the base file you should add the nameservers on lines like:<\/p>\n

\r\nnameserver 192.168.1.1\r\nnameserver 192.168.1.2\r\n<\/code><\/pre>\n
Then if you run ‘resolvconf -u<\/code>‘ your nameservers will update to include those from the base file.  However you may get some additional nameservers showing up, if you have them designated in \/etc\/network\/interfaces with the “dns-nameservers” option, eg <\/p>\n
dns-nameservers 192.168.1.11 192.168.1.12<\/code><\/pre>\n
If you have the same nameservers set in both places (the base file and the interfaces file) they will only show up once in \/etc\/resolv.conf<\/p>\n","protected":false},"excerpt":{"rendered":"
