A free and simple solution, while not bullet proof (no content filter
is that I am aware), is Open DNS. They are even CIPA compliant in the
US: <a href="http://www.opendns.com/solutions/k12/" target="_blank">http://www.opendns.com/solutions/k12/</a><br>
</div></blockquote><div><br>That's what I set up for our pilot school, which was very easy as the XS's DSL connection has a static IP. OpenDNS provides different filtering options, which you can customize as necessary. Being in the US, CIPA compliance is absolutely vital to retain certain federal funding, and OpenDNS was the quickest and easiest way to accomplish that. Dansguardian can be CIPA compliant, but there are other steps involved and I was wary of unintentionally running afoul of the rules. <a href="http://dansguardian.org/?page=faq#15">http://dansguardian.org/?page=faq#15</a> Not to mention Dansguardian consumes server resources. OpenDNS doesn't use any server resources and you can easily configure the filtering to be CIPA compliant. <a href="http://www.opendns.com/solutions/k12/cipa/">http://www.opendns.com/solutions/k12/cipa/</a><br>
<br>As far as limiting the internet connection to authorized XOs, that's an issue we're probably going to run into at some point once we broaden the XS deployment. So far at the pilot school, the staff members connect to the internet with their personal laptops and iPhones, but I haven't really heard any complaints of abuse yet.<br>
<br>If your deployment is relatively small, it should be easy enough to add the hardware addresses of the trusted XOs to dhcpd.conf and disallow unknown machines (or play pranks on them as suggested at <a href="http://www.ex-parrot.com/~pete/upside-down-ternet.html">http://www.ex-parrot.com/~pete/upside-down-ternet.html</a>).<br>
