Login and become root:
sudo su -
Update your stuff (maybe? I dunno whatevs)
pacman -Syu
Install DNSMASQ otherwise, wtf?
pacman -S dnsmasq
make a directory
mkdir /etc/dnsmasq.d
add that directory to dnsmasq's config FOR NARNIA!
echo 'conf-dir=/etc/dnsmasq.d,.bak' >> /etc/dnsmasq.conf
Make a domain file because reasons... so with the editor of your choice add the following to this file: /etc/dnsmasq.d/lan.bib:
bogus-priv
local=/bib/
listen-address=127.0.0.1
expand-hosts
domain=easybib.bib
Now delete that old nasty resolv.conf file (it was a symlink on my system
rm /etc/resolv.conf
And with your fave editor add this to the /etc/resolv.conf file:
nameserver 127.0.0.1
nameserver 4.2.2.1
nameserver 8.8.8.8
Feel free to add your own nameservers or whatever. Maybe you should have looked at what resolve.conf said before you deleted it? Perhaps.
Now, if you're using DHCP it prolly is what is overwriting the resolv.conf file every 2.375 uSeconds. So add nohook resolv.conf to /etc/dhcpcd.conf with your fave editor.
And finally make that stuf start up:
systemctl enable dnsmasq
systemctl start dnsmasq
You likely don't need to reboot at this point but whatev's
So at this point if you add a host to your /etc/hosts file like the following:
10.20.30.1 poop.bib
it'll resolve with ping/dig/et.al. AFTER you do this systemctl start dnsmasq
but you know it's a good way to test... add a domain.bib to the hosts file... dig it (dig domain.bib) and watch it fail then do systemctl start dnsmasq and dig it again... poof it werks!
