Summary

0001956: Add poison DNS tables for DNS resolution.

Description

As an extension to content filtration and to DNS, a simple control applet for the following proposed file allows an administrator to poison a DNS site. This can be useful to block entire domains for a server. While not as advanced as DNSThingy, this functionality can be used to stop global resolution to specific hosts. Coupled with a firewall rule to redirect any outbound DNS requests back in on the ClearOS server, this can force compliance.

This feature supports the IGW initiative.

Additional Information

Create file:

/etc/dnsmasq.d/poison.conf

The contents of this file will contain bogus DNS resolution entries:

address=/example.com/127.0.0.1 #Block users from accessing the social network EXAMPLE.COM

Alternately, the file could redirect to ClearOS www address where the host header is a BLOCK page for *.example.com
