Re: [Server-devel] Dansguardian on XS

2011-04-05 Thread David Van Assche 
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:

- It it usually to restricitive kids or admins can of courrse change
this, but then this becomes pertty mu dansguardian.

- Dansguardian uses Baysian logic to filter out of a lot of the  seriously
otherwise complex keywords/phrases

- I can STILL be uesd with openDNS, to drive down traffic usage

- It i constnantly bein upfated by no only th3 Christian Community agenda,
but muslim and jewish too...

- 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

- It has a major set of pre-fabricated recipes which will save techers adn
admins tim

So--- of u want to use i with OPNDNS u can, an if u choose satnalone vie js
je ehreason .

No, pero hay una tecnica alternativa:

1 - Instala tu propio servidor de DNS que "forwardea" a OpenDNS. Tiene
que tener una IP publica.

2 - Al armar la imagen en olpc-os-builder, agrega un script en
/etc/NetworkManager/dispatcher.d que cuando se establece una conexion
de red, evalua si esta en la red de la escuela (en ese caso, confia en
el XS) o fuera de la escuela (en ese caso, ignora el servidor de DNS
provisto via dhcp y usa el servidor que has instalado en el paso #1

Puedo ayudarlos con el script del paso #2 :-)

 -- In English

for those wanting to provide content filtering both in the school and
outside, there is a good technique based on running your own DNS
server...

 1 - Install your own DNS server (configured with "forwarder" line to
OpenDNS). Must have a public IP address...

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

I can help with the script for #2...

Re: [Server-devel] Dansguardian on XS

2011-04-04 Thread Reuben K. Caron 

German,

You are at a point where you must define your own public DNS server.  
Hosted at your own public IP address. On the following site we show  
the technique. The configuration is not exactly the same but similar:


http://wiki.laptop.org/go/OS_Builder/Adding_OpenDNS_Configuration#Configure_your_public_DNS_server

Basically, DNS queries would be: XO->XS->PUBLIC FOUNDATION DNS SERVER- 
>OpenDNS


As your deployment grows this will also allow you to more easily scale  
your XS installations as they can be preconfigured to point to your  
managed DNS server, instead of trying to find the public IP address at  
each site.


I hope this helps.

Regards,

Reuben

Re: [Server-devel] Dansguardian on XS

2011-04-04 Thread German Ruiz 
En 3 escuelas acá e Nicaragua tienen conexión a internet por un modem
3G (Huawei
3G E968 Wireless
Gateway),
cuando me conecto a internet, y quiero registrar la IP pública en openDNS,
siempre me sale que la IP es 190.212.80.224 ó 190.212.80.225, de igual
manera cuando me conecto desde mi laptop con un modem ZTE
MF626 siempre
me asigna una de estas 2 IP al momento de navegar, supongo que esto es por
el proveedor de Internet que es Claro que está utilizando una proxy para
estas conexiónes.

Para probar registre estas IP en openDNS y apliqué los forwarders
{208.67.222.222; 208.67.220.220;}; en el archivo /etc/named-xs.conf.in,
esperé unos 10 minutos y probé si estaba filtrando en contenido en la
escuela, lo cual no hacía, 5 minutos después, recibí email de usuarios que
aparentemente estaban siendo afectadas por el filtro, (facebook, youtube,
etc...). Por lo que descarte la opción de openDNS para estas escuelas, e
instalé squidguard a como hacen en Paraguay.

Que está impidiendo que openDNS funcione en estas conexiones???
