[K12OSN] Filtering OTIssue 54

[Burroughs, Henry]

Setup squid and SquidGuard.  I'm running that right now, and that site is already covered in the blacklist files.  Now, you have to enable which blacklists you are going to use (ie: hacking, drugs, proxy...) and then squid/squidGuard does the rest.  I am also doing a transparent proxy.

Good luck.
here are more you should block:
thevenue.net/anon/nph-proxy.cgi
atunnel.com
btunnel.com
...
ztunnel.com
heck, probaby *tunnel.com


If you're using squid, try looking through the log files.  Look for
'proxy' 'tunnel' 'anonymous' for sites the students get to.
What about 'legit' sites, take a look at:
http://www.AllAboutAbe.com/
click on the 'abe' pic in the upper left.
there are literally thousands of sites out there for bypassing proxy
servers.  Every once in a while, I'll browse the logs and add a dozen
to the list of sites being blocked.
That first one with nph-proxy.cgi, if you google that, there's a site
where that software is being distributed.  Quite a few people use the
default names, so blockin nph-proxy.cgi in the URL would cover all of
those.  There's one site, oregonlive.com that for some reason uses
that software.
