RE: Real contact at YahooMail
by Hunter Pine 26 Dec '02

26 Dec '02

Yahoo sucks trying to find a real person. It is possible if you call their main office (408) 349-3300 (which you can only find on their site in their Investor Relations section buried 10 or so links away from their home page). Last time I called that number, there was a menu that actually included an option for technical support. You will eventually get someone who will help you, but it won't be easy or fun. They do however have a wonderful policy where they will NOT hang up on you. Just stay on the phone and be a pest long enough until they decide that you're really not going to go away and they magically find a solution to your problem. In my experience, if you actually tell them "I'm not going away until you fix this, keep me on hold all you like, I know your policy", they sometimes give in faster and help you right away. :) If anyone else has a better solution, please cc me, I'd love to have a direct number for someone too. :) Good luck, Hunter Pine > -----Original Message----- > From: davidu(a)everydns.net [mailto:davidu@everydns.net] > Sent: Thursday, December 26, 2002 2:57 PM > To: nanog(a)merit.edu > Subject: Real contact at YahooMail > > > > Does anyone have contact information for a real person at YahooMail they > wouldn't mind passing along? > > Thanks, > David U. >

It is possible to be more or less secure; building a security system -- like a firewall -- that has only the two states of "wide open" and "absolutely impenetrable" is a bad idea.

White House to Propose System for Wide Monitoring of Internet (fwd)
by David Lesher 24 Dec '02

24 Dec '02

[This just jumped into the operational arena. Are you prepared with the router port for John Poindexter's vacuum? What changes will you need to make? What will they cost? Who will pay?] <http://www.nytimes.com/2002/12/20/technology/20MONI.html?pagewanted=print&p…> December 20, 2002 White House to Propose System for Wide Monitoring of Internet By JOHN MARKOFF and JOHN SCHWARTZ The Bush administration is planning to propose requiring Internet service providers to help build a centralized system to enable broad monitoring of the Internet and, potentially, surveillance of its users. The proposal is part of a final version of a report, "The National Strategy to Secure Cyberspace," set for release early next year, according to several people who have been briefed on the report. It is a component of the effort to increase national security after the Sept. 11 attacks. The President's Critical Infrastructure Protection Board is preparing the report, and it is intended to create public and private cooperation to regulate and defend the national computer networks, not only from everyday hazards like viruses but also from terrorist attack. Ultimately the report is intended to provide an Internet strategy for the new Department of Homeland Security. ..............................

Bogus ASN tracking
by Rob Thomas 23 Dec '02

23 Dec '02

Hi, NANOGers. Bogon prefixes aren't the only bits of garbage one will find in the Internet routing table. There are also bogus (unallocated, reserved, and private) ASNs to be found therein. Please take a moment to check my Bogus ASN Report. I have recently enhanced it a bit to include the full path and better tracking. The report is updated hourly, and you will find it here: http://www.cymru.com/BGP/asnbogusrep.html Comments and feedback are always welcome! Thanks!

Analyzing The Cidr Report (fwd)
by Lee Howard 23 Dec '02

23 Dec '02

I've agreed to analyze the CIDR Report, to understand why people don't aggregate more/better, as suggested below. I'll look into AS701, and (time and security permitting) any other UUNET ASN. I do expect to make my findings public, at least in summary form. Whatever I find will be more useful if other operators do the same, so we can present an overall analysis of many of the top "offenders" of poor aggregation. At first glance, it looks like it may not require too much time, but I would like to agree on a methodology and a final report format. So if anyone from any of the operators listed below would like to work jointly, reply privately and we'll work out the details. -- Lee Howard Lee.Howard(a)wcom.com (703) 886-5231 Sr. Manager Internet Installations, WorldCom IP Policy and Allocations ---------- Forwarded message ---------- Date: Fri, 13 Dec 2002 22:00:00 +1100 (EST) From: cidr-report(a)potaroo.net To: cidr-report(a)potaroo.net Cc: nanog(a)merit.edu, eof-list(a)ripe.net, apops(a)lists.apnic.net, routing-wg(a)ripe.net, afnog(a)afnog.org Subject: [apops] The Cidr Report This report has been generated at Fri Dec 13 21:45:30 2002 AEST.

Optical interface failure rates
by David Waitzman 23 Dec '02

23 Dec '02

Historically, optical interfaces have had lower reliability (MTBF) than electrical interfaces, of the same rate, due to a high burnout rate for the lasers. This has apparently changed now, and optical failure rates are lower. Do customers perceive this as true? Do you know of estimates for MTBF for lasers vs copper, for example, 1Gig ether O versus E? Assume that we're talking VSR usage; otherwise copper wouldn't be suitable. And in terms of all optical interface types, if you want roughly 10Gbps speed but are agnostic about how, what about OC192C POS interfaces versus 10Gig Ether? thanks, -david waitzman

Softhome/Yahoogroups-Resolved
by blitz 22 Dec '02

22 Dec '02

The problem has been resolved. THANK YOU ALL! Seems there was a congestion prob that was leading softhome to blackhole anything outbound to yahoogroups. This was the cause of the mail looking like it was directed to RFC1918 space. After some discussion with people on both ends, a workout was achieved. Doug, Brian, hats off...thanks. I know you're reading this somewhere. I personally want to thank the people, too numerous to cite individually who got both softhome and yahoo net people into the loop. I know there were more than a few nanogers involved, things just don't go this smooth otherwise. You people are like firefighters, unappreciated until we need you. The reports I got from you all were informative and helped us bring this to a successful and rapid conclusion. A lot of people who have no idea how the net functions are sending mail again, without knowing there was even a problem. I'm usually cited here as more a PITA than a contributor here, but I do give credit where due, thanks to you all, from the traceroutes, and digs, and the prodding and private emails (All appreciated). I'm not much for patting the backs, but you people here are the best. My problem was insignificant compared to the daily grief you folks deal with and the bandwidths you manage. I'm proud to associate with you, and extend my thanks. Now you all go have a good, un-interrupted holiday.....may the pagers and C-phones be silent, and the emails be few. Marc Blitz Macronet.net

Yahoogroups
by blitz 22 Dec '02

22 Dec '02

Mail to yahoogroups for two days is giving some strange responses. Mail is attempting to go to 172.16.3.10 when sent to a yahoogroup. This looks real strange....that block is reserved I believe? Wondering why theyre resolving to that address? Router mismanagement? Poisoning? I dont know...but its causing some grief here... Yahoo is real lax in giving some human contact addy, perhaps the esteemed group here can shed some light... Thanks..
