Hi All
Anyone saw the "10vor10" -report about blocking access to child pornographic sites yesterday evening?
I'm really surprised, that bigger ISPs like Cablecom now would support that. Interesting is also the statement, that smaller ISPs already confirmed their support for this "preventive blocking"...

I think this started here in CH in about 1996 or 1997 - we used to get lists regularly of sites to block. The lists had at the time about 20 or 30 sites - looks like it's grown quite a lot since then. They used to be mostly sites with political speech that most European governments find offensive.
There were a few approches until now, already with low success or technical implications (other sites also blocked, etc.)
The discussion now happend on society level. Any bigger ISP will never offically reject such blocking requests for child pornography in a tv interview as this can hardly hit their image in the public.
The technical questions of the blocking are completly fadet out. They didn't really care anyone. Blocking can and will definitivly not work. Endusers can implement workarrounds in less than a minute. Other questions like, who's maintaining the list etc. are not even discussed.
I'm really concerned about the way that this story will/ can go...

Full Ack. After this letter arrived, I wrote a blog entry: http://www.blogg.ch/index.php?/archives/444-Kampagne-Stopp-Kinderpornografie...
Few days later I got a call from the journalist of SF who did the report in 10vor10. Means: the journalist was perfectly aware of all the technical and political issues in this case, but he masked out it completly. IMHO a bad job, 10vor10.

Bad, probably. Maybe they feared it getting out of hand. Explaining things like DNS, IP addresses and virtual hosts in a few minutes so that Joe User understands might not be that easy. On the other hand though, that's the problem with nearly every computer related topic today.
They could at least have mentioned that it is very easy for a halfway skilled computer user to circumvent these blocking attempts of the providers though.

I saw it too.
I was quite surprised as we got this letter too and were asking ourself how to block such sites technically. I must confess, we did not find any faisible solution.
=> Blocking the IP-Addresses of the sites. Affecting many other sites hosted on an affected ISP. Many ways to dodge those blockings by means of open proxies on other networks or even using sixxs net via ipv6.
=> Redirecting all traffic to port 80 via a transparent proxy. Breaks many applications like NTLM Authentication etc. Easy to dodge by the same technique as mentioned above.
Still the best way is to notify the affected ISP that they host Child-Porn. I don't think they know about it. If they do, notify their uplinks. I guess they would get disconnected rather quickly.

I think the you can only block this pages when they are blocked by arin.net else. it's now way to block it realy. In the clip they have written all providers will be written. I know that some providers hasn't receive this letter.
