I’m used to editing /etc/resolv.conf to add nameserver information. So when I recently faced an issue resolving dns queries,
# ping bitbucket.org ping: unknown host bitbucket.org
I tried editing /etc/resolv.conf, but found the following in it:
# cat /etc/resolv.conf
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
Apparently the solution is to edit the file /etc/resolvconf/resolv.conf.d/head (Ignore the lines which say the file should not be edited) and add lines like these (Google Public DNS):
# cat /etc/resolvconf/resolv.conf.d/head
Now regenerate resolv.conf with the following command:
# resolvconf -u
ping bitbucket.org PING bitbucket.org (18.104.22.168) 56(84) bytes of data. 64 bytes from 22.214.171.124: icmp_req=1 ttl=54 time=45.9 ms
