This frogans thing? Hoax?

I'm sure you've all received your "reserve your frograns address now" emails by now. We're debating internally whether this is an elaborate hoax, or a dot.bomb that hasn't yet run out of VC cash. I'm interested in nanog'ers take on it? - Dani

OT: The End of Empire

Something to perk up your Tuesday... -- mikey Forwarded-by: Gene Spafford <spaf(a)cerias.purdue.edu> Forwarded-by: David Farber <dave(a)farber.net> Forwarded-by: Stuart Staniford [mailto:stuart@silicondefense.com] Forwarded-by: Shamim Mohamed <shamim(a)languid.org> Darth Vader took two giant strides toward the immense visiscreen that occupied the forward wall of the bridge of his flagship Imperial star destroyer. "We've got them now," he rumbled. Whirling on the technicians cowering at their consoles, Vader snapped, "Tractor beam!" "Yes, Lord Vader," replied one, bending attentively to his task. Then he looked up hesitantly. Vader gestured dramatically at the screen, indicating the fleeing spacecraft. "I want a tractor beam on that ship," he declared. "Now!" The technician busied himself with switches and dials. "Where's that tractor beam?" roared Vader, his voice dark with menace. The other technicians turned frightened eyes on their peer. They knew what happened when Darth Vader's instructions weren't executed instantly. "The tractor beam seems to be down, sir," quavered the technician. "What do you mean down?" Vader inquired with a disturbing silkiness to his voice. "It's not accepting commands, sir," the technician explained. Another technician leaned over and examined the console. "That's odd. The beam itself is showing green," he pointed out. "Yes, I know," agreed the first. "But I'm not getting any acknowledgment to my 'Engage' command." He pressed a button several times to demonstrate. "Maybe the network's down again," suggested a third technician. "Oh, that could be," admitted the first technician. "The network might be down, Lord Vader," he informed the large black figure trembling with rage. "What network?" Vader asked ominously. The second technician jumped in. "Since we've moved to a distributed architecture on the Imperial star destroyers, everything is on a network. It was felt that the direct connections were too unreliable." The third technician added. "The tractor beam is on one of the peripherals sub networks, with the printers and the scanners. It's not on the main weapons network." "Why isn't the tractor beam on the weapons network?" asked Vader, now more puzzled than angry. The technicians exchanged sheepish looks. It was embarrassing to have to point out something so obvious to a superior. The second technician cleared his throat. "Well, sir, the weapons network is a higher priority. It makes more sense to put the less commonly used systems on a separate sub network that has lower QOS." "QOS?" Vader queried. "Hang on a second," said the first technician. "If the network is down, how come we're getting a green light for the tractor beam?" The third technician brightened. "Ah! Maybe the console is retrieving old MIB data and displaying that." "MIB?" rumbled Vader. The first technician answered "We use SNMP to monitor the network elements. When the server queries the element, it stores its current status. If the network goes down, it can't query the element anymore, and all you have is the latest status in the MIB." He turned to the other technicians, musing. "We really should have an indicator of when the last successful query was, instead of just a green or red light." "Good idea," said the third technician. "I'll call tech support." "Say," said the second technician. "How about if we ping the tractor beam? Let me bring up a telnet window." "Telnet?" asked Vader, now obviously confused. "Ping?" The first technician glanced briefly at Vader, a little annoyed at the interruptions. Why couldn't this guy keep up with the service bulletins? "The system runs Unix, but the consoles run NT 5000," he replied with exaggerated patience. "You need a telnet window to ping the element." He turned his attention back to the screen. "That's strange. It comes back 'active'. Listen, when you get tech support tell them we can't engage the tractor but we can ping it." "Right," said the third technician. "I'm still on hold." "Here's a thought," said the second technician. "What if we just call the guys down at tractor control and have them engage the beam manually?" Vader seemed to brighten up at this, and swiveled his head from one to another. "Good idea," said the first technician. He lifted his communicator and tapped the switch several times. "Nothing," he said. The second technician shook his head. "Didn't we tell them we couldn't do voice and data with that little bandwidth?" Suddenly Vader noticed the visiscreen and let out a bellow of anger. "They're gone!" he boomed. The third technician looked up smiling.

Getting an AS and /18
by Andy Ellifson 10 Jul '01

10 Jul '01

I have a customer that is a cable modem provider. They submitted the form to request an AS and some address space. The response from ARIN wanted a ton of documentation. I understand why ARIN requires all of the documentation. Does ARIN require a ton of SWIPS be present for the customer before they will issue address space? This customer genuinely needs the address space but doesn't have the time to gather up all the information that is 'required'. Does anyone know of a person they can talk to at ARIN to help with this process? -Andy Ellifson __________________________________________________ Do You Yahoo!?

Cisco RFC1997 implementation clarification.
by John Fraizer 10 Jul '01

10 Jul '01

While researching an RFC1997 issue this morning, I made the following observations: According to RFC1997: " Well-known Communities The following communities have global significance and their operations shall be implemented in any community-attribute-aware BGP speaker. NO_EXPORT (0xFFFFFF01) All routes received carrying a communities attribute containing this value MUST NOT be advertised outside a BGP confederation boundary (a stand-alone autonomous system that is not part of a confederation should be considered a confederation itself). NO_ADVERTISE (0xFFFFFF02) All routes received carrying a communities attribute containing this value MUST NOT be advertised to other BGP peers. NO_EXPORT_SUBCONFED (0xFFFFFF03) All routes received carrying a communities attribute containing this value MUST NOT be advertised to external BGP peers (this includes peers in other members autonomous systems inside a BGP confederation). " On Cisco's site at http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/12cgcr/np1_… I find the following: " internet - Advertise this route to the Internet community. All routers belong to it. no-export - Do not advertise this route to EBGP peers. no-advertise - Do not advertise this route to any peer (internal or external). local-as - Send this route to peers in other sub-autonomous systems within the local confederation. Do not advertise this route to an external system. " Unless I'm mistaken, there are some potential interop issues with this. CISCO no-export = RFC1997 NO_EXPORT_SUBCONFED CISCO no-advertise = RFC1997 NO_ADVERTISE CISCO local-as = RFC1997 NO_EXPORT Can someone more familiar with the RFC1997 implementation in IOS comment on this?

Re: The MSN Messenger

Well, we are one of those small ISP's. Our company, over the past 6 years, had an association with a larger ISP. This larger ISP had customers in a Metroplex area as well as customers in South America. If you believe in the old adage, all things are equal, when everyone is running the same two programs (MSIE & Netscape) and same type of equipment, then the percentage of trouble tickets would be the same in a small ISP as it would be in a large one. On one occasion the President of the larger ISP call and ask if I could come down for a meeting. So I did. The main topic of this meeting was, why were we having less customer complaints, than the big boys. Both companies were handling everything the same. My answer was, we started a Help Desk. Everytime something went wrong, I sent out an e-mail. The e-mail detailed the problems and how long I thought it was going to take to fix. If during the repair, we found it was going to be longer, I sent another e-mail to our customers. Upon repair, I sent another e-mail and explained the problems and include, if the repair was a band-aid or a solid repair. I also e-mailed our group about planned outages, C&W problems, etc. Well it have been 6 years and I am still writing the e-mails. But now, we call the "Vidnet -- Alerts" In our last poll, I asked if our customers wanted the "Alerts" stopped. To my surprise, a 100% of the users that replied stated, "No, keep up the good work." So, I don't believe you can go wrong, if you keep your customers informed. It doesn't matter if you are an ISP or a Software Company. The more information you can supply to the customer, the happier the customer. Even if they don't understand everything in the e-mail... Respectfully, Morris Allen President VidcomNet, Inc.

IN-ADDR.ARPA Progress Report
by ARIN IN-ADDR Role 07 Jul '01

07 Jul '01

Goal: Reduce the size of the IN-ADDR.ARPA zone file. This file will be reduced in size by only containing name servers for /8 networks. Completed Steps: Apr 2001 - Established relationships with 2 companies to provide independent server networks for all ARIN IN-ADDR zone files. Jun 2001 - Released a new IN-ADDR.ARPA zone file generator to correct existing erroneous data. Next Step: July 9, 2001 - ARIN will begin revising the IN-ADDR.ARPA zone for those direct /8 delegations to ARIN. These /8 zone files will be serviced by the two ARIN nameserver networks. These changes will not affect the performance of reverse lookup in any of the IPv4 Address space. Please direct any questions to inaddr(a)arin.net.

The MSN Messenger
by Sean Donelan 07 Jul '01

07 Jul '01

Since it is always difficult to predict how long it will take to fix a problem, the question for the PR people always is: Do you say as little as possible, hoping it will be over soon? The problem with this strategy is if your problem continues for a long time, you look incenitive or even incompetant. Do you confirm you have a problem, and provide customer updates? The problem with this strategy is you draw attention to minor issues, which few people would have noticed otherwise. After four days, Microsoft finally added a statement to their MSN Messenger web site. I guess Microsoft's PR people decided they couldn't make things worse at this point. > July 6, 2001/8:00 pm PST > > MSN Messenger is currently experiencing a service outage for many > customers on a worldwide basis.

The Cidr Report

This is an auto-generated mail on Fri Jul 6 23:00:00 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. 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. Please send any comments about this report directly to me.

Building NOCs
by Timothy Brown 06 Jul '01

06 Jul '01

Hi NANOG, hope everyone had a great July 4th. Our operation is at a stage where it's time to really invest some money in building a classy network operations facility. Our data center functions are handled seperately, so at this time, this is merely a place for housing operations staff. I've searched the cctec archives and found a few really old threads regarding how to tackle the NOC building process. We're a systems house, but I imagine the principles exist along the same lines. Obviously, some of the principles from building data centers apply here - i'm not totally out of my depth. I've thought about things like lighting, ergonomics, information sources, phones, power, environmental, etc. What i'm really looking for from the community are a) links to manufacturers of good NOC gear, b) recommendations on the above, and c) financial worksheets detailing cost proposals, if any. In addition, any contractor suggestions would be greatly appreciated. When I say NOC gear, what I really mean is NOC furniture, large information displays, and guidance/standards on how to build facilities. It's been a long time since i've done this sort of thing on any kind of a serious level. Since I know that some of the information i'm requesting is proprietary, feel free to eliminate the names of the accused and reply privately off-list. I'll summarize if it looks necessary. Thanks, Tim
