Fwd: Document Action: 'TCP SYN Flooding Attacks and Common
by Fergie 01 Jun '07

01 Jun '07

Sorry to interrupt the v6 chaos discussion, but I figured that this might be of some interest to folks on the list. Since the IESG, IAB, etc. has forward this to the RFC Editor queue to be published as an Informational RFC, I think is a good thing. One thing, however, that troubles me, is the title -- which I think is somewhat misleading. While I think it is a fine and thorough document, it is really not about mitigating TCP SYN flooding attacks, really, but more about lowering the threshold of pain. In any event... it's a nice document. :-) FYI, - ferg [forwarded message] From: The IESG <iesg-secretary(a)ietf.org> To: IETF-Announce <ietf-announce(a)ietf.org> Date: Thu, 31 May 2007 10:07:00 -0400 The IESG has approved the following document: - 'TCP SYN Flooding Attacks and Common Mitigations ' <draft-ietf-tcpm-syn-flood-05.txt> as an Informational RFC This document is the product of the TCP Maintenance and Minor Extensions Working Group. The IESG contact persons are Lars Eggert and Magnus Westerlund. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-tcpm-syn-flood-05.txt Technical Summary This document describes TCP SYN flooding attacks, which have been well-known to the community for several years. Various countermeasures against these attacks, and the trade-offs of each, are described. This document archives explanations of the attack and common defense techniques for the benefit of TCP implementers and administrators of TCP servers or networks. Working Group Summary The consensus within the TCPM WG to publish this document as an informational RFC is strong. Protocol Quality This document details several techniques that have been used in TCP implementations for many years. The technology discussed in this document is not new, but rather this document is helping the RFC-series "catch up" with common practice and details experience with several mechanisms. Personnel The document shepherd for this document is Mark Allman (TCPM co-chair). The responsible AD is Lars Eggert. _______________________________________________ IETF-Announce mailing list IETF-Announce(a)ietf.org https://www1.ietf.org/mailman/listinfo/ietf-announce [end] -- "Fergie", a.k.a.

Port 1080 probes from AOL
by up＠3.am 01 Jun '07

01 Jun '07

One of my virtual web host servers have been getting multiple probes to TCP port 1080 (socks) every day for months from AOL IP addresses. Is AOL known to be doing something relatively innocuous on that port? I ask because I have portsentry null routing IP addresses that make probes like this. TIA, James Smallacombe PlantageNet, Inc.

I understand some questions recently arose regarding Microsoft and Teredo. I tried reading through the archives but it has more twists that Pacific Coast Highway. Are there some specific requests/questions that I can help with? Best Regards, Sean Siler Sean Siler|IPv6 Program Manager|Microsoft sean.siler(a)microsoft.com<mailto:sean.siler@microsoft.com> | 703.485.1170 http://blogs.technet.com/ipv6 IPv6 is ready. Are you?

Re: IPv6 Deployment
by Fred Heutte 31 May '07

This is more in the way of a leading question for those who are attending NANOG 40. I'll ask it the same way I did at NZNOG back in February -- what problem is it that IPv6 is actually supposed to solve? I used to know the answer to this, but I don't now. In 1997 (or even years before, reading Scott Bradner's eloquent advocacy for it back then) it would have been: address space, security, extensions, QOS. But it seems to me these have either been sidestepped, addressed somewhat, or the benefits have not overcome the costs in a clear business case sense. As I said -- my purpose in posing this is to stimulate discussion at Bellevue. It was the most interesting thing talked about at Palmerston North, at least until the cold beer arrived. fh

Lightning talks at NANOG 39!
by Steve Feldman 31 May '07

31 May '07

We have reserved one hour of the NANOG 39 agenda for "Lightning Talks". A lightning talk is a very short presentation or speech by any attendee on any topic relevant to the NANOG audience. These are limited to ten minutes; this will be strictly enforced. If you have a topic that's timely, interesting, or even a crackpot idea you want to share, we encourage you to consider presenting it. The Program Committee will decide which submissions are relevant (using criteria based on the NANOG mailing list AUP) and choose the best six to be presented. Use of slides is optional. All slides must be in PDF or Powerpoint format, and will be loaded in advance onto the speaker laptop on the podium. There is a good overview of the use of lightning talks at the Perl conference at http://www.perl.com/pub/a/2004/07/30/lightningtalk.html. Although their format is slightly different, many of their ideas will apply here. To submit a lightning talk proposal for NANOG 39, go to http://www.nanogpc.org/lightning/ See you in Toronto!
