OT - On 9-11 Search Engine Activity - from First Monday
by Frank Coluccio 07 Nov '01

07 Nov '01

>From the closing paragraphs of: http://firstmonday.org/issues/issue6_10/wiggins/index.html "The effects of September 11th on the Leading Search Engine" "As we have seen, the Internet played an important role in the dissemination of urgently-sought news about the unfolding events. Some aspects of the design of the Internet make it very effective in crisis. An important example is the inherent ability of TCP/IP to re-route and deliver data when important communications links are broken, as in war, or as in the September 11 tragedy. This robustness is not surprising, given that TCP/IP was born out of DoD-funded research." Are these principles being eroded as we type? In any event, Kudos to all of you NANOGers, for all of the work that you do each day. Frank Coluccio DTI Consulting

dns @ home.com

Is anyone else having issues retrieving dns/MX from them? Sometime today, we became unable to lookup their MX, leaving a bunch of mail destined for them in limbo, yet, I can dig/nslookup the MX using many outside dns servers. Nothing has changed on our end, and I'm at a loss for an explanation, so now I'm curious if I'm the only one? -- Yours, J.A. Terranson sysadmin(a)mfn.org If Governments really want us to behave like civilized human beings, they should give serious consideration towards setting a better example: Ruling by force, rather than consensus; the unrestrained application of unjust laws (which the victim-populations were never allowed input on in the first place); the State policy of justice only for the rich and elected; the intentional abuse and occassionally destruction of entire populations merely to distract an already apathetic and numb electorate... This type of demogoguery must surely wipe out the fascist United States as surely as it wiped out the fascist Union of Soviet Socialist Republics. The views expressed here are mine, and NOT those of my employers, associates, or others. Besides, if it *were* the opinion of all of those people, I doubt there would be a problem to bitch about in the first place... --------------------------------------------------------------------

Last NYC 9/11 Internet repairs
by Sean Donelan 07 Nov '01

07 Nov '01

As of November 2 2001 every Internet circuit I knew damaged during or as a result of the terrorist attacks in New York City, Pentagon and Pennsylvania has been repaired, re-routed, or replaced by alternative service. Or, regretably, were no longer needed by customers. Of course, this is only anecdotal information.

Yes there was a lapse in payment. This was addressed yesterday, all should be back to norm. I was a bit surprised to see that people are still pointing to ra.net. Chris Frazier Merit

RE: out-of-band network experiences
by Kevin Gannon 06 Nov '01

06 Nov '01

For our outof band management we do a number of things based the customer: 1. All sites must provide an ISDN dialin to a customer router giving us telnet access from a large central secured RAS. The NOC team telnet to the RAS and type ras>customer_name Conecting to 1.1.1.1 A very small number of staff can view the config of this RAS everyone else can just type "customer_name" they can not even look up these from the RAS. You either know the name or you get zip.Without this access the customers SLA for support calls is zip. They will get 4 hours HW swap only. 2. NOC Monitored customers we will use a diverse FR PVC this gives IP access to all the routers from behind layers of firewalls/secureid. We also use a Async link from our remote router to at least one Core routers console/aux. This is very useful for spotting things like power problems and crashed routers. All these sites will also include option 1 as the NOC team does *not* have direct IP access only telnet for SW upgrades a senior NOC manager has to be involved. 3. IPSec Tunnels , this is a new thing for us and its only starting to emerge and it is nearly always backed bu option 1. 4. Async modems attached to console/AUX ports this is managed in the same way as option 1. This is only used when ISDN is not an option for example for manage a lot of kit in remote telecoms shelves which do not support ISDN. 5. For the telecoms side we mostly depend on the inband signalling and some core SDH/ATM sites will have outofband using a combination of the above. In fact the last time I asked I was told they run X.25 pad,IP over X.25,IP over D channel,LAPD over timeslots,Async IP tunelling, CLNS over just about everything and 600 modems. The biggest problem by far is managing past your outofband port. I dont know how many customers are running 10.x.x.x so polling for stats using Openview became such a pain. We came up with another solution ;-).

It is generally a terminal server connected to the equipment console ports, with a dialup modem for external access. A few (very few) providers have a dedicated out-of-band management network. Generally a frame-relay circuit to a management hub/router connected to the async terminal server and low-speed (10 meg) ethernet port on some routers. One problem with high-end routers, it is either expensive (lost opportunity cost) or impossible to connect low-speed circuits to high-end routers. Non-facility based providers often purchase their out-of-band circuits from a different provider than their primary circuits. AT&T is a popular supplier for out-of-band management networks. AT&T may not be price/competitive for high-bandwidth circuits, but for 64k/128k frame-relay management links, it may make sense. Carrier/facility based providers tend to use their own facilities. Yep, facility based providers have cut their own facilities in the past, including one provider which took their own NOC off-line for most of a day.

Getting back to normal: Hurricane Michelle
by Sean Donelan 06 Nov '01

06 Nov '01

First, as always, the important information 5 people died in Cuba during Hurricane Michelle. Electric and telephone lines are still down in the western part of the island. Electric power was turned off by authorities before the storm. International telephone service has been restored, but reaching people in Cuba is still spotty. Internet service appears to be fuctional, but determining the true physical location of a host is always a guess. Hurricane Michelle missed most of South Florida and is moving away from the Bahamas.

RE: Confidential outage Saturday October 20 2001
by Sean Donelan 06 Nov '01

06 Nov '01

> So, did any customers of the unknown carrier notice an outage? > As several people pointed out, there was also an earlier confidential outage report on August 2 2001. The FCC website has been updated, and the previously "hidden" carrier name for both confidential outages appears to be Sprint. But the reports are still confidential. http://www.fcc.gov/Bureaus/Engineering_Technology/Filings/Network_Outage/20… http://www.fcc.gov/Bureaus/Engineering_Technology/Filings/Network_Outage/20… Customers noticed several minor outages on October 20. But I couldn't figure out why Sprint would require confidential treatment for any of them. The confidential report back in August seems to indicate whatever the reason for confidentiality, it has nothing to do with post-September 11 environment.

RE: IP allocations...

My understanding of Rich's words "subdelegating internally" would be delegations for corporate lans, pop devices, dialup pools, and so forth, rather than customer assignments. Depending on which he meant, the two roles are very different. Having said that, we are migrating to QIP for everything. :-) > At 12:45 AM +0000 4/11/01, Joshua Goodall wrote: > >On Thu, Nov 01, 2001 at 07:24:29AM -0500, Rich Sena wrote: > > > >> What is everyone using for subdelegating IPv4 space > internally - looking > >> for an *ease of use* tool - something that would require > low maintenance > > > and can be delegated to entry-level NOC staff... > > > >I would be cautious about handing your address-space management to > >entry-level staff.

OK, facility builders.... Who makes rackmount keyboard trays/shelfs/whatever you call 'em. Not the ordinary slide out ones; but "scissor-jack" kind that you can swing out and change the height of.... Failing that, ones that don't height-adjust but not those sliding straight out. -- A host is a host from coast to coast.................wb8foz(a)nrk.com & no one will talk to a host that's close........[v].(301) 56-LINUX Unless the host (that isn't close).........................pob 1433 is busy, hung or dead....................................20915-1433
