Network Level Content Blocking (UK)
by James Blessing 12 Jun '07

12 Jun '07

Hi all, Sorry for the cross posting to a number of lists but this is an important topic for many of you (especially if you get multiple copies). As many people are aware there is an 'expectation' that 'consumer' broadband providers introduce network level content blocking for specified content on the IWF list before the end of 07. Whilst this is seen by many as a honorable political crusade to 'protect the innocent' many with a strong technical background are concerned that the long term impact on network development will lead to major 'breakages' within the internet. So far the only debate has revolved around the legal concerns that the introduction of this technology imposes to problems on the ISP: 1. Revocation of mere conduit status; by inspecting certain content and preventing access to it the ISP is doing more that just passing packets and is getting involved in the content. 2. Thin end of the wedge; if we can block Child Abuse Content then we can block copyright infringement.... 3. Increased liability; by blocking the content at a network level outside of the control of the user the ISP is potentially opening it self to a lawsuit should content leak through the block (although many are saying that this is not going to be enforcable it could still tie up people in court going through the arguments with no guarantee of a win cf mere conduit issue above). LINX (the London Internet Exchange) and ISPA are looking to arrange a day to address the technical issues of placing such a block in the network. The topics are expected to include: 1. Implementation - how do you put this into place 2. Scalability - how do you provide a non-degrading service 3. Circumvention - how do you stop people getting round the block 4. Reverse Engineering - how do you hide the block (should you hide it?) 5. Messaging - what do you tell the person about what you just done 6. Legality - what is the legal impact of this 7. Security - who should have access to what 8. Sanity Checking - how to prevent poisoning of the block list 9. Testing - how do you make sure that the block is working 10. Reality - is this actually the best way to do this We have 13 companies involved so far but really want to get as many ISP's together to make sure that people understand the implications of the governments request. Whilst the intent is to focus the content on the technical side we are keen to make sure that the all parts of the ISP industry are brought up to date so may run multiple strands with different levels of technical content if we have the numbers. If you are interested please contact John Souter (john(a)linx.net) or Malcolm Hutty (malcolm(a)linx.net) for more details.

NANOG 40 Peering BOF XV Meeting Notes now on-line
by William B. Norton 11 Jun '07

11 Jun '07

Hi all - We had a large and lively group discussion at the Peering BOF XV at NANOG 40 last week in Bellevue. I tried to capture the essence of the discussions embedded with Matt Peterson's photos of the event. For those who could not attend (or could not hear because we packed folks in all the way into the hallway), I hope these notes will give you a sense of what was discussed. NANOG 40 Peering BOF XV Meeting Notes: http://www.nanog.org/mtg-0706/Presentations/PeeringBOFXVMeetingMinutes.pdf Bill PS - I fully expect that there are errors, and that folks who presented their case to the group could provide some better text. Please send me your update(s), or, alternatively, it might be interesting to have the community edit the google docs file: http://docs.google.com/Doc?id=dddj3pds_22gqrdqs Send me email to bill.norton at gmail.com and I will add you as a collaborator to the document if you have updates to make. -- //------------------------------------------------ // William B.

If so, combine it with colo, admin and hardware costs and > its certainly not "zero-cost" for us I think theres a bit too much focus being given to the implementation side of this problem. The Internet is currently a very cheap industry to set up in, compare to say becoming a telco in the 90s with large licensing fees and huge capex for startup. If the government says the Internet services need to provide X Y and Z at $ cost then so be it. I think the real issue is the technology and the perception it has. It is being imposed on operators to violate routing strategies and add these /32s which cannot scale, additionally inserting web caches many years after web caches ceased to be defacto with all the issues and reduced service level they come with. And after doing all this we are blocking on a tiny hand managed list, this doesnt even compare to early spam blocking systems and look how ineffectual they were! The scary part is this is being cited in parliamentary sessions as being the holy grail of child porn fighting. That is the real worry. Yes it is relatively expensive to implement, yes it can only be done through a series of hacks and violations to protocol and no it doesnt provide 1% of real protection or help to push forwards the anti child porn goals. So why are so many ISPs keen to sign up? Well any number of reasons - PR, political pressure, fear of being branded pro-child porn by the media. I think we as an industry can do so much better to find solutions to this problem without pandering to the first crazy idea that our PR mad government comes up with. Steve

eBay == 2620:0:500::/41, oops (Was: IPv6 filterers watch out: eBay gets 2001:0:500::/41)

Eric Vyncke wrote: > Beware the subject line is wrong, it assumes that eBay is using Teredo ;-) > > (you scared me for a while!) Oops, indeed, some other people also noted this already. And it is good to see that people read subject lines, as due to recent nanog-banter I would almost have believed that nobody did. Of course it should not really matter which exact prefix they got, as long as folks keep their filters up to date. Greets, Jeroen (who blames the sunlight in his screen in the early morning :)

IPv6 filterers watch out: eBay gets 2001:0:500::/41
by Jeroen Massar 09 Jun '07

09 Jun '07

Hi, As the below is of course a 'good to see they are going at IPv6' thing this one is of course nice. But there is an additional point in it which might cause folks to check up on their filtering: it's a /41. Just to make clear again, ARIN IPv6 PI allocs can be of size /40 - /48. So better check your filters if this can get through when they get around doing so ;) My suggestion: use the relaxed filters (2000::/3 = /16 - /48). When crunch-time comes that there are 1m routes, you can always filter more specifically, but as we are still < 1000 routes, give yourself and your routers some slack... Enjoy the weekend (we have sun in Dublin *wow*, jump in garden :) !

If there's a Symantec/Veritas admin lurking....
by Frank Bulk 08 Jun '07

08 Jun '07

...seer.support.veritas.com is not resolving. A check of two DNS propagation testers show that less than 15% of the DNS servers out there can resolve it. If you go to http://www.symantec.com/enterprise/support/knowledge_base.jsp?pid=15047 and search for any document (try 286144) you'll likely see timeouts for the popup windows. And I tried calling corporate and got nowhere....they shuttled me to enterprise product support. =( Frank
