That's not the way I see this at all. I look at it as a good complement to anti-spoofing filters as part of defense in depth, in case said filters get SNAFUed. My primary line of defense will remain ACLs. Michel.

Looking for opinions and experience on Tiscali IP network performance within Europe and out of Europe i.e. North America on the whole.. I have heard mixed reports, but am looking for information from those with first-hand experience either on transit or peering level. Would they be classed in top-three performing networks in Europe (recent bandx report gave them #1 spot)? If not what are you recommendations on reaching the largest amount of eyeballs on a very stable network primarily in Europe. Thanks in advance for your time. Regards, Shazad

OT: Determining toll free # ownership
by Jon R. Kibler 07 Apr '04

07 Apr '04

Hi, I know this is somewhat off topic, but I am hoping someone here has previously dealt with this problem and has an answer. For some reason, the access telephone number for our "internal use only" dial-up modem pool -- which also happens to connect to our fax server -- has gotten on several fax spammers telephone list as being a fax telephone number. We have captured several dozen faxes sent through that number over the past few days, and they all have 'enter your number here to delete' toll free numbers on them and we would like to find out the telco that owns those blocks of 800# so we can complain. I have heard that there is a number that you can call, enter a telephone number -- such as the toll free number we want to complain about -- and it will tell you the telco that owns that phone number. Does anyone know what that number is? Thanks! Jon Kibler -- Jon R. Kibler Chief Technical Officer A.S.E.T., Inc.

Anti-Spam Router -- opinions?
by Andy Johnson 07 Apr '04

07 Apr '04

Has anyone had any experience with this device? Turntide.com. Looks like a traffic-shaping device designed specifically for cutting down spammers throughput to your inbound SMTP servers. My main concern is, how does it make the distinction between legitimate mass-mailings (e.g.: mailing lists such as this one), and spam? Interesting approach to killing spam though I must say. -Andy

NSA wiretap leads to arrest
by Sean Donelan 06 Apr '04

06 Apr '04

Operational as far as service provider capability to assist lawful interception of networks. Previous NANOG meetings have dealt with the topic. There are several other forums for related comments. http://www.globetechnology.com/servlet/story/RTGAM.20040406.gtterror06/BNSt… Citing anonymous sources in the British intelligence community, The Sunday Times reported that an e-mail message intercepted by NSA spies precipitated a massive investigation by intelligence officials in several countries that culminated in the arrest of nine men in Britain and one in suburban Orleans, Ont. -- 24-year-old software developer Mohammed Momin Khawaja, who has since been charged with facilitating a terrorist act and being part of a terrorist group. The Orleans arrest is considered an operational milestone for this vast electronic eavesdropping network and its operators. But Dave Farber, an Internet pioneer and computer-science professor at Carnegie-Mellon University in Pittsburgh, said the circumstances are also notable because it will be the first time that routine U.S. monitoring of e-mail traffic has led to an arrest.
