Filter Performance Fix

If web browser speed has been reduced by >10% on workstations running web filtering, implementing the following GNC script will install and configure DNSmasq to create a local cache for DNS requests. More information on Groovix NetCustomization can be found on the Groovix NetCustomization page.

Note: Administrative privileges and knowledge of implementing Groovix NetCustomization scripts are both necessary to follow the steps indicated below. It is highly recommended that the following be handled by an IT professional or with assistance by Groovix Tech Support.

Groovix NetCusomization script

apt-get-dontask install dnsmasq
perl -pi -e 's/#prepend domain-name-servers 127.0.0.1/prepend domain-name-servers 127.0.0.1/' /etc/dhcp3/dhclient.conf
perl -pi -e 's/#listen-address=.*/listen-address=127.0.0.1/' /etc/dnsmasq.conf
/etc/init.d/networking restart
