Interesting netflow entry
by Wil Schultz 08 Feb '06

08 Feb '06

After setting up netflow this morning I have a of recurring flow that seems bothersome to me. I have an internal host (10.X.X.99) that continually attempts to hit various external hosts (AA, BB, CC, etc...) on seemingly random ports but always sources port udp.1204. In about 2 hours this host has hit 155 different external hosts, some of them once or twice and some of them more than 10 times. Below is a sanitised 10 minute output. 11:41:37.031 0.000 UDP 10.XX.XX.99:1204 -> AA.AA.AA.AA:46299 (RoadRunner, VA US) 11:42:07.032 0.000 UDP 10.XX.XX.99:1204 -> BB.BB.BB.BB:15989 (Comcast, MI US) 11:42:37.096 0.000 UDP 10.XX.XX.99:1204 -> CC.CC.CC.CC:52566 (Comcast, IL US) 11:43:17.204 0.000 UDP 10.XX.XX.99:1204 -> DD.DD.DD.DD:47756 (Adelphia, CA US) 11:45:27.521 0.000 UDP 10.XX.XX.99:1204 -> EE.EE.EE.EE:20797 (Tokyo) 11:46:07.685 0.000 UDP 10.XX.XX.99:1204 -> FF.FF.FF.FF:21363 (Surrey UK) 11:48:47.991 0.000 UDP 10.XX.XX.99:1204 -> GG.GG.GG.GG:48324 (Israel) Interestingly enough, I've checked to see if this seemingly random port was actually listening and each of the 15-20 hosts I've checked are all listening on their port, i.e. AA.AA.AA.AA has udp.46299 open while BB.BB.BB.BB has udp.15989 open. When a host was contacted multiple times the "random" dstport is always the same. Anyone have any clue on to what could be going on here? -Wil

NANOG36 PGP Key Signing
by Majdi S. Abbas 07 Feb '06

07 Feb '06

The key signing will be on Monday at 3pm in the State room. If you can't make it, feel free to submit keys as there will be a follow-up session during the Wednesday morning break. So get those keys in and I'll see you in Dallas! --msa -snip- Stickers for Your Name Badge When you stop by the registration desk at NANOG36, there will be colored stickers available for your name tag that indicate if you have an interest in signing PGP keys. If people keep trying to peer with you, you've picked up the wrong color sticker and should go back. How the Key Signing Works Those of you who plan to participate should email an ASCII extract of your public key to msa(a)latt.net by 10:00 p.m. CST on Sunday, February 12. Please include 'NANOG PGP KEY' in the subject, and if possible, don't send your key as a MIME attachment. I realize that some MUAs make this difficult, and I will attempt to fix any MIME-attached keys. Instructions for extracting your key to an ASCII file are below. After noon on the 13th, a complete key ring with all of the submitted keys will be available at puck.nether.net/~majdi/nanog36.pgp in binary form, and as an ASCII file at puck.nether.net/~majdi/nanog36.txt. Handouts with the details of each key submitted will be provided. All you should need to bring with you is: * Photo ID (driver's license, passport, etc.) * Your key ID, and its fingerprint * A pen Thank you, and I'm looking forward to seeing you all in Dallas! How to Extract Your Public Key to an ASCII File PGP 2.x: pgp -kxa your_email_address mykey.asc PGP 5.x: pgpk -xa your_email_address > mykey.asc GnuPG: gpg --export --armor your_email_address > mykey.asc PGP on Windows: Start the PGPkeys application, select your key in the list, click on the Keys menu, select Export, name the resulting file, and make sure that Include Private Keys is NOT checked. PGP on a Mac: I assume the procedure is similar to the one for Windows, but cannot confirm this. Hopefully it's easy enough to figure out.

RE: Triple Play [was: CAUTION: Potentially Dumb Question...]

I think the main challenge in making this type of media distribution a reality is not the technology, we mostly know how to make it work. The real challenge is the content owners' willingness to make the content available while preserving their IP rights. > -----Original Message----- > From: owner-nanog(a)merit.edu [mailto:owner-nanog@merit.edu] On > Behalf Of Christian Kuhtz > Sent: Tuesday, February 07, 2006 7:46 AM > To: Sean Donelan > Cc: nanog(a)merit.edu > Subject: Re: Triple Play [was: CAUTION: Potentially Dumb Question...] > > > > On Feb 7, 2006, at 10:27 AM, Sean Donelan wrote: > > > On Mon, 6 Feb 2006, Christian Kuhtz wrote: > >> If you're near real time, you have lots of options actually.

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
