[Server-devel] wwwoffle?

[Andra DuPont]

Dan,
Great news on your shell scripting skills..... as I haven't done any. Yes, the mutual exclusivity of wwwoffle and squid would be one part. Below are some earlier comments from Martin that help define the opportunity/plan better.

From Martin's first thoughts on automating wwwoffle....
>> 
>> - Can we remove the need to set proxy on every XO by either...
>>   - using a transparent proxy, same as we do with SQUID (maybe make a
>> TURN_ON_WWWOFFLE script)?
>>   - serving a proxy autoconfig file via dhcp/apache?
>> 
>> - Is it viable to automate the "go online / go offline" with a
>> cronjob that pings a public host ( ping -c1 google) every 5 minutes?
>> Or...
>> 
>> - If there's a daemon managing the connetion (case of pppd), use the
>> "down" and "up" hooks? This would only work if the daemon catches the
>> "link is lost" situation reliably.

A follow up note from Martin with some additional detail/thoughts....

I am running wwwoffle on an XS in Kenya, and it is helping out a lot. In fact, we have loaded up a ton of educational site pages to the XS while on high speed connection, and all this material is available to the students even when the XS is offline, which is most of the time. We have created courses in Moodle where the topics are groupings of educational categories, and each educational site is add to the topic as a "link to a website" resource.
