Using dnsmasq for local DNS caching

Asked by Tong Sun

Hi,

I'm following https://help.ubuntu.com/community/Dnsmasq to config my dnsmasq. I've done everything, but still can't get DNS from local caching server. Here are the details:

I've done everything:

$ grep domain-name-servers /etc/dhcp3/dhclient.conf
prepend domain-name-servers 127.0.0.1;
. . .

$ grep listen-address /etc/dnsmasq.conf
listen-address=127.0.0.1

$ cat /etc/resolv.conf
nameserver 127.0.0.1
nameserver 192.168.0.1

See, all the configuration done. Now:

% service dnsmasq restart
 * Restarting DNS forwarder and DHCP server dnsmasq [ OK ]

$ dig ubuntu.com
;; Query time: 8 msec
;; SERVER: 192.168.0.1#53(192.168.0.1)
   ^^^^^^^^^^^^^^^^^^^

$ dig ubuntu.com
;; Query time: 53 msec
;; SERVER: 192.168.0.1#53(192.168.0.1)
   ^^^^^^^^^^^^^^^^^^^

DNS request is still going through 192.168.0.1.

FYI, local DNS caching is working fine:

$ dig debian.org @localhost
;; Query time: 69 msec
;; SERVER: 127.0.0.1#53(127.0.0.1)

$ dig debian.org @localhost
;; Query time: 0 msec
;; SERVER: 127.0.0.1#53(127.0.0.1)
   ^^^^^^^^^^^^^^^^^^^

Please help

thx

This is Ubuntu 10.10 Maverick,

Can you give the output of:

cat /etc/resolv.conf

Thanks

OMG, didn't you see that I've already posted that pal:

$ cat /etc/resolv.conf
nameserver 127.0.0.1
nameserver 192.168.0.1

Now, having the above tweak and doing a reboot, my eth0 is not started any more. How should I enable my eth0 by default.

$ cat /etc/networks

link-local 169.254.0.0

$ cat /etc/NetworkManager/nm-system-settings.conf

I use dnsmasq myself in this way, all I changed was the listen address, I didn't change any other file. Do you use a netowkr management app, or do you just edit the network config files manually?

I just edit the network config files manually, no GUI involved.
