Necessary Censorship: Web Filtering with Open Source (Linux Journal)
The Linux Journal looks at open source censorware systems.
"Maybe we need open-source censorware, strange as that may sound, with
a publicly available list. It would offer the ability to tinker with
both the code and the list to suit the needs of folks who have to do
this type of work.
I was stunned by the answer I found: two such animals already are
available." It's an interesting article with a worthwhile topic: what do you do when you have to impose some sort of filtering?

Necessary Censorship: Web Filtering with Open Source (Linux Journal) Posted Apr 16, 2003 14:27 UTC (Wed) by edstoner (guest, #4496) [Link] I agree (mostly) with the author of this article. I am a systems administrator for a public school district in Pennsylvania. We were forced to do content filtering in order to receive erate funds. Last year we switched from CyberPatrol to a system I wrote in-house so that we could have local control over what gets filtered and so that the filtering would actually work (if anyone thinks that a url list solution can actually filter well they've never ran a filtering solution in a school district). The proxy server I wrote is available under the LGPL at http://www.digitallumber.com/willow. The most recent version supports Bayesian filtering of content and works quite well. Some comments about running a filtering proxy for a school district (including why url blacklists don't work) are available at http://www.whsd.k12.pa.us/admin/technology/filtering/whsdfiltering.html.
Necessary Censorship: Web Filtering with Open Source (Linux Journal) Posted Apr 16, 2003 18:57 UTC (Wed) by gbailey (guest, #58) [Link] I've been interested in software that would do this for a long time. I eagerly downloaded the software, only to discover that I needed some extra python modules (like "nameserver") which I discovered in the "oak" DNS server. Okay--downloaded that, and now I need the "Crypto.Cipher" library?Forgive me as I'm not a python guru at all, it's just not clear where/how to obtain these necessary modules. I can't find much documentation either to tell me what modules are needed. Surprised this software isn't listed in FreshMeat.net.. seems really useful and can't wait to get it working--Ed, can you help out? Thanks,
