Re: SMURF AMPLIFIER BLOCK LIST -- VERY LARGE!!!!!!!!!!!!!!!

Well, the ranges... >164.128.116.0 >164.128.119.0 >164.128.122.0 >164.128.123.0 >164.128.57.0 >164.128.81.0 ...are ours, and they are used in our backbone infrastructure. I was a bit surprised to see some of our backbone addresses on the list, because a few weeks back I went around all of the potential amplifiers and configured no ip directed-broadcast. I turns out that the ranges mentioned are all used to address serial access lines to customers - they are all /30 or /32. I have a bit of a problem with blocking of address ranges that really cannot be used as significant amplifiers. We take our responsibilities an ISP seriously: we have blocked all LANs that are connected by fat pipes and/or have large amplification factors, and we have started configuring 'no ip directed-broadcast' on ALL interfaces as a matter of standard. But we have several hundred legacy /30 interfaces that can't be reconfigured overnight. While I support the sentiment that ISPs responsible for large amplifiers should be blocked until they take action, I feel that the decision to block an address range should actually be tempered by an assessment of how damaging an amplifier the address block represents. If a smurf attack is detected from an address range, is it really that difficult to check what the amplification factor is before deciding if it should go onto a blocking list? I would certainly suggest that /30s should not be blocked, since they are so numerous and the damage they can cause is limited. How about a compromise: two lists - one of known smurf amplifier ranges > /30, which are blocked, and another of ranges where the amplifiers are =< /30, and which are no blocked, but simply publicised? As another thought, maybe what we need is a rough 'smurf effectivness metric' composed of amplification factor and access bandwidth. If address ranges only get onto the list because an attack has been sourced from them, then it should be possible to approximate these numbers.

NANOG 13 REMINDER
by Pam Ciesla 04 May '98

04 May '98

The block on the hotel rooms ends Wednesday, 5/6. Be sure to reserve your room. All attendees need to register via the website, if you are unable to do this please contact me. The attendee list is current. The following is the agenda so far: SUNDAY AFTERNOON TUTORIAL: Introduction to RPSL (Cengiz Alaettinoglu, ISI, Curtis Villamizar, ANS) Find out about Routing Policy Specification Language, which will succeed RIPE-181 as the language used to express policy in the Internet Routing Registry. A description of the tutorial is available HERE. SUNDAY EVENING TUTORIALS Introduction to Multicast (Dave Meyer, Cisco) Interesting Things You Can Do With OSPF (Howard Berkowitz) After an introductory overview of the OSPF interior routing protocol, Berkowitz presents some interesting case studies of useful but non-obvious things one can do with OSPF, if one is willing to think "outside the box." The tutorial concentrates on determining requirements and network design, rather than detailed configuration, emphasizing ways that a high-powered OSPF domain can be a viable alternative to BGP for many customer and internal ISP applications. Also includes information about practical address management with OSPF. QoS and Ebone: Issues and Potential Solutions (Sean Doran, Ebone) Discussion of RED/QoS issues for the Ebone. Click here for a detailed overview of the talk. Network-based Denial of Service Attacks: Descriptions and How to Protect Your Network (Craig Huegen, Cisco) Recommendations on Queue Management and Congestion Avoidance in the Internet (Van Jacobson, Lawrence Berkeley National Laboratory) What Is a VPN? (Paul Ferguson, Cisco Systems) Definition of Virtual Private Networks and overview of approaches to building VPNs. Read the paper, by Ferguson and Geoff Huston, HERE. Dial-in VPN Using Layer 3 Tunneling (Gary Malkin, Bay Networks) Review of the Virtual Private Networking topology and problem space, overview of encapsulation and tunneling, and Bay Networks's DVS solution. Broadband VPNs - Outsourcing ISP services to Cable TV and XDSL Providers (Bruce Perlmutter, Bay Networks) Data over cable TV and xDSL are technologies that are experiencing enormous growth as a means to provide high speed Internet access to consumers. Most implementations of these technologies require the cable provider to become an Internet Service Provider (ISP) - a business for which they are often ill prepared. This presentation describes an architecture that allows cable providers to outsource the ISP function to a number of partner service providers. The cable provider installs and manages the physical plant, and bills the customer for services (voice, video, data) delivered over this plant. Data traffic from these customers arrives at the cable provider head end and is routed to an Internet Service Provider (or other data network) selected by the customer. Even though the customers are connected to a common access infrastructure (XDSL or cable TV), they appear as though they are connected only to their selected ISP. This approach can be called a Virtual Private Network. Issues discussed include: IP address allocation and packet routing, accounting and authorization mechanisms, and encryption and privacy issues. Roadmap to a Distributed Registry: Transition to RPSL (Routing Policy System Language) (Cengiz Alaettinoglu, ISI, Curtis Villamizar, ANS) Differentiated Services Panel: Working Group Update and Viewpoints From the Community (Kathleen Nichols, Bay Networks, moderator; Van Jacobson, Lawrence Berkeley National Laboratory, Fred Baker. Cisco, Peter Ford, Microsoft Building Large-Scale Internet Measurement Infrastructure (Vern Paxson, Lawrence Berkeley National Laboratory) Scaling and Other New BGP Features (Mark Turner, Cisco) Recent work on BGP scaling issues, including support for peer groups over multiple IP subnets, prefix lists, neighbor route count limits, and Cisco Express Forwarding/QoS interactions. ARIN Update (Kim Hubbard, ARIN) InterNIC Update (Mark Kosters, InterNIC) Path and Round-Trip Time Measurements: a New Project at CAIDA (Daniel McRobb) Implementing Simplex IP Bandwidth Augmentation and IP-Based News and HTTP Broadcast Services via Geosynchronous Satellite (Avi Freedman, Net Access) Covers details of implementing half-duplex satellite bandwidth augmentation and news/web cache broadcast over satellite. Net Access does all three on one signal; for bandwidth augmentation, a Cascade-based solution and a Cisco IP-tunneling-based solution will be presented. Introduction to the NETPERF.NET Inter-Provider Network Performance Monitoring Project (Avi Freedman, Net Access) Sponsored by Net Access, the project deploys pairs of servers (one web server, one query box) at each provider being studied, and generates semi-real-time NxN graphs of packet loss, latency, and throughput between the various providers.

SMURF amplifier page
by Karl Denninger 04 May '98

04 May '98

As promised, we now have a web page for this. The current smurf list is at http://www.mcs.net/smurf This will be updated roughly weekly, or whenever major changes are made to the list of blocked networks. It contains, in addition to dialogue on the Smurf issue, a list of network numbers and "whois" lookups on the owners. IF YOU APPEAR ON THIS LIST YOU CANNOT TRANSPORT PACKETS INTO OUR INFRASTRUCTURE. Instructions for what you must do to get the block removed are contained within this page. Bitching and moaning is pointless - the only fix is to FIX THE PROBLEM. Thank you! -- -- Karl Denninger (karl(a)MCS.Net)| MCSNet - Serving Chicagoland and Wisconsin http://www.mcs.net/ | T1's from $600 monthly / All Lines K56Flex/DOV | NEW!
