Filter Performance Fix

!!UnderConstruction!!

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.

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.

Groovix NetCusomization script

apt-get-dontask install dnsmasq
gncget --mod=644 /etc/dhcp3/dhclient.conf
gncget --mod=644 /etc/dnsmasq.conf
/etc/init.d/networking restart

After the install, the following files need to be updated:
diff dhclient.conf.default /etc/dhcp3/dhclient.conf
20c20
< #prepend domain-name-servers 127.0.0.1;
---
> prepend domain-name-servers 127.0.0.1;

diff dnsmasq.conf.default /etc/dnsmasq.conf
90c90
< #listen-address=
---
> listen-address=127.0.0.1 </div>
