url category database, flat file lists, or API
by JoeSox 25 Jul '12

25 Jul '12

Does anyone know of a open source database, flat file lists, or API that allows me to feed a url and have it return a category classification For example, something like this http://www1.k9webprotection.com/support/check-site-rating I know of dansguardian but it doesn't have battlefield.com as a game site and is more of a blacklist. I thought I saw one a few years back but it was only for linux but still had categories. -- Thanks, Joe

Comcast cable modem software update push
by Dave Sotnick 24 Jul '12

24 Jul '12

Dear Nanog Users, I have recently been plagued by intermittent lockups on my Motorola BitSurfer 6121 cable modem, which I purchased based on Comcast's lists of recommended devices, and having good experience with Motorola products in the past. There's a good discussion on this topic here: http://goo.gl/SfHdh My technical question for the group is: When I finally talk to Comcast Tier 2 this week, what do I need to tell them to convince them that pushing out an update to SB6121 modems is a good idea? They seem convinced the onus is on Motorola to provide updates. This is not how DOCSIS 3.0 works! FWIW, the installed OS is 1.0.3.3 dated Aug 12 2010. The most recent I have heard of is 1.0.6.6. Apparently this fixes the lockups. Any tips greatly appreciated. -Dave

Pittsburgh IX?
by ML 24 Jul '12

24 Jul '12

I was looking for information on any IX in Pittsburgh. Found PitX [1] ..info is rather limited to say the least. Is there any information out there about participants, size, etc? Are there any other IXes in or near Pittsburgh by chance? I see 3Rox out there but seems to be a R&E network mostly. -ML [1] http://www.pitx.net/

HE Fremont IPv6 tunnel
by Jeroen van Aart 23 Jul '12

23 Jul '12

Recently I migrated the server that's running an HE IPv6 tunnel to one of the Fremont endpoints and now the tunnel is going down for a few minutes every couple of hours or so. I haven't been able yet to find a reason for this. I made sure the old server is not running any IPv6 related things anymore (such as radvd). I am curious if anyone knows if the Fremont endpoints are experiencing some problems? I have barely ever noticed any problems with the IPv6 tunnels so I am pretty sure it's not on HE's side, but I wanted to make sure. Thanks, Jeroen -- Earthquake Magnitude: 4.6 Date: Sunday, July 22, 2012 06:32:50 UTC Location: Santa Cruz Islands region Latitude: -10.6712; Longitude: 164.7985 Depth: 37.00 km

Postini/google email admin assistance requested
by Lyle Giese 22 Jul '12

22 Jul '12

I run a smaller email filter service for clients and starting Saturday, we are experiencing heavy traffic aimed at one email account. 99% of the traffic is coming from obsmtp.com servers. In the last 24 hrs, we have been getting over 1,000 attempts per hour to this account with a couple of peaks at 4,000 per hour. Not sure if they can help but an offlist contact from them would be nice. Sorry for the noise to the rest! Lyle Giese LCR Computer Services, Inc.

Re: Attack on UDP 101
by Shahab Vahabzadeh 21 Jul '12

21 Jul '12

Dear Stefan, I have an 7206VXR Router with this design: int gig 0/1: directly connected to 3750 switch (uplink to internet) int gig 0/2: vlan termination from PSTN centers int virtual-template1: xdsl users Its about 4 days that I see near 300Mpbs outbound traffic in int gig0/1 that there is no such a traffic in none of routers interface, but the same traffic is seen in 3750 peer interface. I try to run monitor session on 3750 and monitor port traffic which I see that packet is generating from a user and its in a loop between 3750 and 7206. When I disconnect that user, I see that that packet is in loop again, because of that I am sure its making a loop but I do not know the reseaon is that packets or not.
