Change the contents of the /etc/resolv.conf file by adding only Google's Nameserver 8.8.8.8 to the following:
Generated by NetworkManager
domain guate.net.gt
search guate.net.gt
# Add google DNS (edited by JL)
nameserver 8.8.8.8
# Keep the remaining nameservers
nameserver 10.52.56.1
nameserver 10.4.24.1
nameserver 10.26.24.1
# NOTE: the libc resolver may not support more than 2 nameservers.
$ The nameservers listed below may not be recognized
nameserver 10.63.64.1
nameserver 68.238.96.12
nameserver 68.238.112.12
Since /etc/resolv.conf file is regenerated to default settings after each reboot, we need to ensure the above modifications are persistent. This can be done by issuing the command:
sudo chattr +i /etc/resolv.conf
