Updating DNS on Roving Edge Infrastructure Instances

Update the Domain Name Service (DNS) settings on your system to include the nameservers the instance can reach.

To preserve your edits to the /etc/resolv.conf file, run the following command:

chattr +i /etc/resolv.conf

Inclusion of the +i attribute in the command protects the /etc/resolv.conf file on Linux so that no one can modify it, not even the root user.

To remove the write protect attribute, run the following command:

chattr -i /etc/resolv.conf
