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.

CU, Venty

Title: Converted from Rich Text

 
 

Blocking is as well political activism as nonsense, as long as many of the childporn-sellers set up as many as 20 sites a day on yahoo. These sites are pointing on perfectly legal sites on which one can make a payment for receiving a password which enables user to get into a p2p-network where the cp-material is distributed. 
Furthermore: ISPs would have to update the list all day and night - a neverending job. 
And as long as some police departments in some other countries are setting up cp-sites as a trap and therefore are actively distributing child pornography, the whole "plan of action" as described in TV becomes pretty weird. 
Are elections soon? 
But anyway, if Cablecom _really_ wants to block all these sites, the responsible guy may contact me off-list. I'll be glad to send him may daily harvest of cp-addresses :-p

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...

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.

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.

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...


cheers,
michel

their

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.
