Use dnsmasq to speed up ADSL Internet access

Dnsmasq is used to speed up the Internet access of ADSL-Debian, a Linux release technology. For more information, see the following. This article uses DNSmasq to create a local DNS Cache library to improve browsing speed by reducing the time for the browser to interpret domain names

1. Install dnsmasq
Apt-get install dnsmasq

2. Edit the configuration file of dnsmasq.
Apt-get vim/etc/dnsmasq. conf

Find the following item
# Resolv-file =

Replace with the following statement
Resolv-file =/etc/resolv. dnsmasq. conf

3. Copy the original dns configuration to resolv. dnsmasq. conf.
Make sure that you have not changed the/etc/resolv. conf file.

Cp/etc/resolv. conf/etc/resolv. dnsmasq. conf

4. Edit resolv. conf.

Vim/etc/resolv. conf

Remove all domain name servers and add the following lines
Nameserver 127.0.0.1

Save and exit

5. Edit the adsl link configuration file to prevent resolv. conf from being overwritten after pppoe automatically connects to the network.

Vim/etc/ppp/peers/dsl-provider

Add # Before usepeerdns, that is, overwrite this statement.

6. Restart the dnsmasq service.
If you do not restart, you will find that the domain name cannot be resolved.

/Etc/init. d/dnsmasq restart

You can also change the dns address to opendns settings.

The address of opendns is (modify the/etc/resolve. dnsmasq. conf file ):
Nameserver 208.67.220.220
Nameserver 208.67.222.222
