How to check the DNS I am using on Linux?
Posted on In QAMy Linux distro is Linux Mint 17 (Ubuntu 14.04.1 LTS (Trusty Tahr)). I am using NetworkManager.
The old trick does not work:
$ 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
nameserver 127.0.1.1
If you are using NetworkManager, the /etc/resolv.conf will point to your machine to dnsmasq as configured by NetworkManager. You can get the real DNS server you will use from NetworkManager by:
nm-tool | grep DNS
That would be “nm-tool” (without the “s”).
