I'll file that comment where it belongs -- in file 13. If a major catastrophe, albeit more human than network-related (although lots of network-related issues here, too), isn't on-topic, than I fail to see what is. - ferg -- Richard A Steenbergen <ras(a)e-gerbil.net> wrote: Did I miss the memo announcing the Slashdot commentary section had been extended to the NANOG mailing list?

If I read the timestamps correctly, your posting arrived via the NANOG list *after* the domain had been pulled.

You get high marks for your crumudgeon level. However, if I have to point it out and lead you to it like a child, then so be it. If I was mistaken in thinking that the referenced article: "Red Cross looks to IT for post-Katrina recovery" http://www.computerworld.com/securitytopics/security/recovery/story/0,10801… ..would perhaps elicit some operational suggestions from the peanut gallery on how to perhaps assist in this effort, or prhaps contribute to the BellSouth issues, etc., then mea culpa. Sniping certainly accomplishes nothing. - ferg -- Richard A Steenbergen <ras(a)e-gerbil.net> wrote: On Wed, Aug 31, 2005 at 01:22:13AM +0000, Fergie (Paul Ferguson) wrote: > > I'll file that comment where it belongs -- in file 13. > > If a major catastrophe, albeit more human than network-related > (although lots of network-related issues here, too), isn't on-topic, > than I fail to see what is. North American Network Operations perhaps? Talking about the impact to networks is on-topic, talking about steps being taken to protect or restore networks is on-topic, talking about networking infrastructure as it relates to the public communications infrastructure is on-topic during an event like this. Replying to idiotic slashdot articles asking really stupid questions is not on topic. Telling the entire NANOG reader base that you like your POTS line and will never switch to VoIP is not on topic. Technically speaking a human tragedy isn't even on topic. Like I said, it might be different if there was some actual insight being provided here. If someone was talking about some specific data relating to the reliability of the infrastructure or otherwise something OPERATIONAL to talk about that would be one thing, but this is not operational, this is simply chatter. Chatter has its place, that is why people read Slashdot and watch the news, but replacing an operational mailing list with the slashdot commentary section and seeing what happens is not my or anyone else's idea of a good time. -- Richard A Steenbergen <ras(a)e-gerbil.net> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC) -- "Fergie", a.k.a.

Phone networks struggle in Hurricane Katrina's wake
by Fergie (Paul Ferguson) 31 Aug '05

Via Reuters. [snip] Telephone companies struggled to restore service and measure the damage to their networks in Louisiana and Mississippi on Tuesday after Hurricane Katrina cut power and triggered severe flooding. A spokesman for BellSouth Corp., the largest local telephone company in the region, said while the company estimated about 53,000 lines were out in the two states, the actual numbers were likely to be higher. Cingular Wireless and Sprint Nextel Corp. said cellular service in the area had been affected as well. All three companies said power losses were the main threat to further service failures, but that flooding was hampering their efforts to reach network equipment. Entergy Corp. reported more than a million customers without power in Louisiana and Mississippi, and warned customers to expect a long and difficult restoration that could take weeks. New Orleans Mayor Ray Nagin told television station WWL that 80 percent of the city was under water, and authorities declared martial law in some areas.

MPLS or Site2Site VPN
by Todd Reed 31 Aug '05

31 Aug '05

I'm looking at connecting 15+ multi-state locations together to start forming a private corporate network. The sites are small with 25-30 devices. I want to avoid direct-T1's due to cost, therefore I'm looking for alternatives. I know I can do site-to-site VPN, but I've also heard a lot about MPLS and from what I've read, it may be a good option. Over the next year, we will be adding 5-10 more sites, so expansion is important. I'm not planning to do voice, but it may be an option in 2-3 years. If anyone has any suggestions on their experiences, I would greatly appreciate it. Thanks, Todd

A useful oversimplification for network surveillance?
by Howard C. Berkowitz 30 Aug '05

30 Aug '05

I'm developing some guidance for ISP surveillance for infrastructure attacks, and my increasing impression is that for other than the expert level, there may be some useful simplifications of the applicability of tools. Remember that I am speaking of surveillance here, not the detailed analysis in a sinkhole. Perhaps this could be the basis of some security architecture presentations/tutorials at NANOG. Let me put up the following strawmen and invite people with flaming torches to go for them, with the caveat that these simplifications are for an introduction to the topic. NetFlow is the key to analyzing traffic patterns outside the router, looking for DDoS signatures when known, and for traffic anomalies that may become DDoS. SNMP is the key to analyzing the effect of exploits on network elements. For example, NetFlow might tell you there is a flood directed at TCP port 179, but your router may implement rate-limiting/policing such that the control processor doesn't see this flood and processor utilization stays within reasonable ranges. Syslog and SNMP traps focus on physical events by people (e.g., reconfiguration), physical problems ranging from temperature alarms to router and interface shutdown, and exploits against security mechanisms. Some of this asynchronous information has undergo root cause analysis: the interface you see go down may be perfectly fine; the problem is in the medium or distant interface.
