> > He hasn't taken broadcast TV delivery into account in the > Triple Play scenario. You gotta plumb them packets good for that... I don't watch anything live anymore, all via Tivo. If Tivo could do bittorrent and download the content, then would I need broadcast? TV model is going to change significantly in the next 3-5 years. Bora

LCP Echo in Cisco Environment
by Ronald W. Jean Jr. 07 Feb '06

07 Feb '06

Good day all, I am curious if anyone is familiar with the role of LCP echo requests in Mobile IP environments to maintain session activity. Specifically, I am wondering does anyone have familiarity with the Cisco CSG (billing) and its ability if any to interpret that traffic. Thanks Ron Jean Miller Technologies Group LLC

On the inoc-dba subject
by Joe Maimon 06 Feb '06

Is it really cluefull to have this paragraph? " Please make sure that your spam filters allow email from "pch.net" before you sign up, since we will need to automatically verify your email address. " Since we all know that whitelisting and blacklisting by in-band stated "from" email address is quite wrong-headed, from a clue standpoint. Perhaps something like this? " Please make sure that your spam filters allow email sent from <ip-addresses> with a from address of pch.net before you sign up, since we will need to automatically verify your email address. " Where <ip-addresses> is the output of a dig command against the outgoing smtp servers sending the notifications? In general, ML and other automated email things should have a way to display the bounce to the user, which would mean storing it for some small period of time. Otherwise it becomes rather difficult to do the right thing filtering wise. (Google seems to do this for their notifications that get 45x/55x) Joe

Lightning Talks at NANOG 36
by Steve Feldman 06 Feb '06

06 Feb '06

We have reserved one hour of the NANOG 36 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 have a topic that's timely, interesting, or even a crackpot idea you want to share, we encourage you to consider presenting it. Signups for lightning talks will be accepted during the NANOG meeting. The Program Committee will accept relevant talks until all the slots are filled. (Details will be announced during the meeting.) Use of slides is optional. Any 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 coference 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. Looking forward to seeing you in Dallas, Steve Feldman PC Chair

NetFlow tools?
by Wil Schultz 06 Feb '06

06 Feb '06

I'm planning to set up NetFlow in my environment within the next few weeks, so far two suites that look promising to me are "flow-tools" and "SiLK". Anyone have any input on which would be better to use (or maybe some other product)? -Wil

TWTC as4323 full routes
by Jon Lewis 06 Feb '06

06 Feb '06

Has anyone else with a transit connection to Time Warner Telecom noticed TWTC on and off over the past few days advertising an extra 2500 or so routes? Right now, I've got 180169 routes from 4323...and 176-177K from other transits. I noticed them setting off my BGP-4-MAXPFX warning :( ---------------------------------------------------------------------- Jon Lewis | I route Senior Network Engineer | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________

as gadi has just discovered there's a whole world out there, he seemed unaware of your all being there so is sending this message to everyone he can find. hence, the message is not private, so i can distribute, and i thought i would save everyone the trouble. [ btw, i personally don't support this ] randy From: Gadi Evron <ge(a)linuxbox.org> To: Randy Bush <randy(a)psg.com> Subject: establishing a global NOG Date: Mon, 06 Feb 2006 21:23:09 +0200 Hello! How are you? After the recent CME-24/BlackWorm incident I finally realized just how large the net-ops world outside of the US really is. I found many people from South Asia, Africa, etc. who were very helpful, serious and knowledgeable yet outside of my normal circles. The global ad-hoc cooperation that took place really made me realize that it is past time for a global NOG to form. We are working on locating leading net-ops people from different NOGs around the world in order to get started. What we have in mind is an open and public group, but with a semi-strict code. I figure we'll figure it out as we go. I'd like to invite you on-board, as well as ask you if you know of others who may be a good addition for our critical mass when we start. Thanks, I'd appreciate any input. Gadi.

RE: Problems connectivity GE on Foundry BigIron to Cisco 2950T
by David Hubbard 06 Feb '06

06 Feb '06

You are using a crossover cable right? If that's all set, you do need to have neg-off on the Foundry and "no nego auto" on the Cisco. I haven't used the rj-45 gbics in the Foundry equipment before, not sure if that could be an issue. I would go with the hard set 1000-full on both sides.
