Howto use Google DNS with ppp

Question

I have a mobile broadband device that I use to connect to the internet. I wish to use the google dns service, their nameservers being 8.8.8.8 and 8.8.8.4. I add them to /etc/resolv.conf but when I connect with wvdial,

➜  ~  sudo wvdial mts
--> WvDial: Internet dialer version 1.61
--> Initializing modem.
--> Sending: ATZ
OK
--> Modem initialized.
--> Sending: ATDT#777
--> Waiting for carrier.
ATDT#777
CONNECT 3100000
--> Carrier detected.  Starting PPP immediately.
--> Starting pppd at Sat Sep  1 19:45:18 2012
--> Pid of pppd: 3298
--> Using interface ppp0
--> local  IP address 180.215.45.164
--> remote IP address 10.228.138.133
--> primary   DNS address 10.228.129.114
--> secondary DNS address 10.228.129.113

This updates my resolv.conf to the new DNS servers. The problem is that my ISP's DNS service is buggy and I wish to use either google dns or opendns. How do I achieve this? I am running chakra linux (2012.08.22 - Claire)

Answer 1

You should have a /etc/ppp/ip-up.d/0dns-up which will setup DNS records, so remove execution bit and use google dns statically.

chmod -x /etc/ppp/ip-up.d/0dns-up

And modify /etc/resolv.conf to use google dns only (you've done that already)
