I''ll probabbly get flamed for this but here goes. These are some of the resons I dont see oppenDNS are as an alternative to aw filter:<br><br>- It it usually to restricitive.... kids or admins can of courrse change this, but then this becomes pertty mu dansguardian.<br>
<br>- Dansguardian uses Baysian logic to filter out of a lot of the seriously otherwise complex keywords/phrases<br><br>- I can STILL be uesd with openDNS, to drive down traffic usage<br><br>- It i constnantly bein upfated by no only th3 Christian Community agenda, but muslim and jewish too...<br>
<br>- IT works absolutely fantastically as a standalone program that uses tinyproxy and firehol and is maintained by a nice small team of devs )8 at lasst cound)... The whole frontend works fast and efficiently on a number of netbooks we teeted at guadalnex.ed<br>
<br>- It has a major set of pre-fabricated recipes which will save techers adn admins tim<br><br>So--- of u want to use i with OPNDNS u can, an if u choose satnalone vie js je ehreason . <br><br><div class="gmail_quote">On Tue, Apr 5, 2011 at 5:04 PM, Martin Langhoff <span dir="ltr"><<a href="mailto:martin.langhoff@gmail.com">martin.langhoff@gmail.com</a>></span> wrote:<br>

</div>No, pero hay una tecnica alternativa:<br>
<br>
1 - Instala tu propio servidor de DNS que "forwardea" a OpenDNS. Tiene<br>
que tener una IP publica.<br>
<br>
2 - Al armar la imagen en olpc-os-builder, agrega un script en<br>
/etc/NetworkManager/dispatcher.d que cuando se establece una conexion<br>
de red, evalua si esta en la red de la escuela (en ese caso, confia en<br>
el XS) o fuera de la escuela (en ese caso, ignora el servidor de DNS<br>
provisto via dhcp y usa el servidor que has instalado en el paso #1<br></blockquote><br><br><br><a href="https://launchpad.net/webcontentcontrol">https://launchpad.net/webcontentcontrol</a> <br><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">

-- In English<br>
<br>
for those wanting to provide content filtering both in the school and<br>
outside, there is a good technique based on running your own DNS<br>
server...<br>
<br>
1 - Install your own DNS server (configured with "forwarder" line to<br>
OpenDNS). Must have a public IP address...<br>

2 - When building your OS image on olpc-os-builder, add a script in<br>
/etc/NetworkManager/dispatcher.d -- the script gets called when a<br>
network connection is established. It must check whether it is in a<br>
school network (in this case, it trusts the XS to filter) or outside<br>
(in this case, it ignores the DNS server provided via DHCP, and uses<br>
instead the DNS server configured in step #1).<br>
<br>
I can help with the script for #2...<br>
