[SOLVED] Resolvconf.conf is only half working

slack_ · 06-26-2014, 11:20 PM

I have dnsmasq set up and working on my Arch server. For some reason though, resolvconf keeps adding IP addresses that I don't specify into resolv.conf. I've done all the steps, I've added nohook resolv.conf to /etc/dhcpcd.conf, and in /etc/resolvconf.conf I've added this:

Code:

name_servers="x.x.x.x y.y.y.y"

It successfully adds those specified addresses, but it also appends two other default ones that I didn't specify. I thought using resolvconf.conf was supposed to stop this.

There's usually a bit in wifi scripts and often in network ones to pass dns servers when you connect to a network by http.
Depending on how the network is set up, you may actually need them, as some networks don't allow access to outside dns servers. They can then easily block sites like facebook, twitter, porn sites, and such like.

I use Slackware, and the variable they use in the script to control this is DHCP_KEEPRESOLV. Try this to find what arch uses:

Code:

grep -ire 'RESOLV'  /etc/rc.d/*  |less

chattr +i /etc/resolv.conf

is what I use for my special DNS

i had a similar problem when i installed hostsblock on my arch linux.

i'm too lazy to remember it all now, but you can read from here onwards, there should be some resolv.conf/dnsmasq related stuff there.

Sorry for taking so long to respond. I didn't want to do the chattr +i method because AFAIK it can possibly mess with other things that may need to access resolv.conf. Fortunately, and also unfortunately, the problem went away but I have no idea why, so I can't post the solution. Sorry. The only IPs in my resolv.conf are the ones explicitly specified in /etc/resolvconf.conf.

Thanks everyone. Sorry I don't have a better result for other people reading this thread.
