Old way:
Examine list of DNS servers in /etc/resolv.conf:
$ cat /etc/resolv.conf– – –
New way:
May not work on newer Linuxes since resolving may be setup via (not only DNS, but also) various other services: DDNS, LDAP, Avahi, Bonjour, ZeroConf and God knows what else.
So…
To check up your DNS server, better use this command:
$ nmcli dev show | grep DNS.. or if the above does not work (meaning you have a “newer” Linux but not “that new” 🙂 ) use:
$ nm-tool | grep DNS
