I want to change the IP address of the DNS server that was set up when OntapSelectDeploy was constructed.
I checked the user guide and the command list of the real machine, but I could not find the change command.
# DNS server information is written in the /etc/network/interface
# I'll try to modify, but this file is READ ONLY!
# edit /etc/network/interface
Could you tell me how to solve it?
