by Sean Donelan 06 Oct '01

06 Oct '01

I'm trying to put together a timeline of events post September 11, and am having a bit of trouble figuring out what happened with 32 Old Slip. There were a several messages about generators not starting, running out of fuel, etc Tuesday evening. If anyone has good first, second or third-hand knowledge about the details, could you send me a note.

The Cidr Report
by CIDR Report 06 Oct '01

06 Oct '01

This is an auto-generated mail on Fri Oct 5 23:00:01 PDT 2001 It is not checked before it leaves my workstation. However, hopefully you will find this report interesting and will take the time to look through this to see if you can improve the amount of aggregation you perform. Check http://www.employees.org/~tbates/cidr-report.html for a daily update of this report. NEW: Check http://www.employees.org/~tbates/cidr-report-region.html for the regional version of this report. NEW: Check http://www.employees.org/~tbates/autnums.html for a complete list of autonomous system number to name mappings as used by the CIDR-Report. The report is split into sections: 0) General Status List the route table history for the last week, list any possibly bogus routes seen and give some status on ASes. 1) Gains by aggregating at the origin AS level This lists the "Top 30" players who if they decided to aggregate their announced classful prefixes at the origin AS level could make a significant difference in the reduction of the current size of the Internet routing table. This calculation does not take into account the inclusion of holes when forming an aggregate so it is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does give some indication of ASes participating in CIDR. Clearly, it is generally a good thing to see a large amont of withdrawls. 3) Interesting aggregates Interesting here means not an aggregate made as a set of classful routes. Thanks to GX Networks for giving me access to their routing tables once a day.

Summary: SNMPv3 implementations
by RJ Atkinson 06 Oct '01

06 Oct '01

I've received numerous requests for information on which network switch/router systems implement SNMPv3, though my own request was for information on operational deployments of SNMPv3 in networks. Folks interested in an *incomplete* list of implementations with SNMPv3 might want to look at: http://www.ibr.cs.tu-bs.de/ietf/snmpv3/#Implementations A number of network equipment vendors have shipped SNMPv3, but are NOT included from that list. So if SNMPv3 is something you are interested in, ask your vendors directly for more information. Of particular interest is the existence of at least one freely distributable implementation "NetSNMP" (formerly UC Davis SNMP). This works out of the box on most modern UNIX systems, meaning that one can use SNMPv3 on UNIX servers even if the OS vendor didn't include it directly. For more on that implementation, browse the above URL. Ran rja(a)inet.org

Re: slightly OT : versign complaint department
by beldridg＠best.com 06 Oct '01

06 Oct '01

hi all, an update to my post (i know, bad form). a friend or two has informed me of a few errors. i think, in general, most people don't understand the relationship between the "registry" and the different "registrars." i've asked this person if a FAQ is possible. here is the update: On Sat, 29 Sep 2001 beldridg(a)best.com wrote: > i've been trying to add a pgp key to the verisign/netsol database for > the past two weeks. i've sent four messages, opened three web help > requests, and spent three hours on the phone with their helpdesk. they > know less than their customers about their own procedures and web > documentation for adding keys for PGP guardian auth. i discovered the whole problem is with the verisign _registrar_ and not the _registry_ (i originally thought the registry owned the database of host and contact records and the pgp keyserver). the _registry_ does own the "canonical" host database, but the only way to make changes is through your _registar_. the _registrar_ is responsible for authenticating end users before updating the _registry_ database. after multiple e-mail support questions, 4 key ADD messages and 4 hours of phone calls, i never got another response from the verisign _registrar_. i finally tried adding a PGP key again and it worked. i guess i woke up the mice on the treadmills in the computers at the verisign _registrar_. i guess the only thing i can do is move my one remaining domain record away from the veri$ign _registrar_. of course, they won't refund the unused portion of my $35 even though their customer service is absolutely horrific (so much for a SLA). i recommend that everybody move their money away from the verisign _registrar_ and use any other one - i don't even care which one. :) - brett

"Virtual" multi-homing providers
by Ng Pheng Siong 05 Oct '01

05 Oct '01

Hello, I'm looking at deploying "POPs" at several IDCs across the globe. Each POP will contain several servers. (At most ten.) I would like each POP to use the same set of IP addresses; connections to these IP addresses will get to the nearest POP by virtue of routing. IOW, I think I'm wanting to have all my POPs belong to one AS, as if said AS multi-homes to each POP/IDC, except that the multi-homing is virtual, because I don't have links from my "enterprise network" to these IDCs. (Well, I don't expect to have much of an enterprise network. ;-) Are there providers of such? Will I be able to get a globally routable IP block for my AS? Or is my best bet to pick one provider which has global presence? (Which such global providers are there? Do people like Exodus or Digital Island count?) TIA for your input. Cheers. -- Ng Pheng Siong <ngps(a)post1.com> * http://www.post1.com/home/ngps

Seeking clueful salesrep for UUnet/MCI and C&W
by JC Dill 05 Oct '01

05 Oct '01

Thanks for all the VERY helpful replies to my query about the backbone that sucks the least. As a followup, I've been asked to locate clueful sales reps for UUnet, MCI, and C&W. Sales people (and others) from those named organizations are given explicit permission to reply to me directly, and techies are encouraged to contact me with the contact info of any sales rep they trust. I already have contacts for AT&T and Genuity, but still need C&W and UUnet/MCI. This is for a company headquartered near Silicon Valley that needs connectivity at 12 US locations plus London and Tokyo.

Hi folks, Anyone familiar with Global Switch? They appear to have recently acquired the assets of colo.com - and possibly other facilities as well. I'm trying to decide whether to keep my assets at colo.com/Global Switch or to transfer elsewhere. Thanks, Tim

RE: staffing guidelines
by Murphy, Brennan 05 Oct '01

05 Oct '01

How many more did you ned for config and support? Suppose too that your network was global, covering EMEA, APAC and North America. I am interested more in how many *engineers* are needed on 200, 500, 2000 device networks, where "device" means routers, switches and any servers that support the routers/switches such as HP Openview, Sniffers or ACS servers, ...Firewalls, etc. Anybody dare to take the number of devices on their network and divide by the number of network support staff you have? Shouldnt there be a paper from Gartner or Giga on this topic? Can anyone reference one? -----Original Message----- From: Dave O'Shea [mailto:doshea@telentente.com] Sent: Thursday, October 04, 2001 4:24 PM To: Irwin Lazar; nanog(a)merit.edu Subject: RE: staffing guidelines I'm sure it varies greatly based on the type of work that's being done, but my experience with another company led me to think that one set of eyes could handle up to about 200-300 devices, purely for monitoring and outage management. Configuration and support was another matter. (When I say devices I mean routers, servers, and manageable switches) To get at a 24x7 figure, I generally multiplied by about 4 or 5 (taking into account shifts, vacations, weekends, etc.) So, for about, say, 1,000 manageable devices, I would expect to need about 16-20 people. The curve improves significantly as you grow and get to use more sophisticated problem isolation methods and tools. -----Original Message----- From: Irwin Lazar Sent: Thu 2001-10-04 14:26 To: 'nanog(a)merit.edu' Cc: Subject: staffing guidelines Is anyone aware of guidelines for IT staffing that are freely available on the web? In particular, I'm looking for guidelines as to the number of staff required to support "N" amount of routers, servers, users, etc. Any links are appreciated. Thanks in advance, Irwin

traffic classification mechanisms
by Robert Pezick 05 Oct '01

05 Oct '01

This query is part of a marketing survey on the utility of today's QoS features. All input would be appreciated. The question addresses the real-world utility of the basic edge traffic aggregation/QoS mechanisms that vendors provide these days, in particular if and how often operators actually use them. A common function in today's edge equipment is the classification of packets based on layer 2, layer 3, and layer 4 packet header fields. In particular, classification based on - layer 2: MAC addresses, ethertype, etc - layer 3: source IP, dest IP, ToS, protocol - layer 4: TCP/UDP source/destination port The edge equipment will generally classify traffic into flows based on these characteristics and then perform some policing and/or marking functions on that stream. 1) Do you use these facilities? rarely, somewhat, often? 2) Are there particular classification methods out of the standard list that you use more often then others? Any help is appreciated. Thanks. - Rob
