It was a suggestion based on incomplete information. Originally I didn't know whether it was overheating due to debris and dust clogging the radiator or mechanical failure. You are correct, it wouldn't help a failed water pump. If Telehouse lets us know what specific parts (model/part number) they need, I can check our spare parts inventory for a possible loaner.

Keeping the lines of communication open
by Sean Donelan 16 Sep '01

16 Sep '01

As things have slowed down, I've had a chance to read some of the other threads. These are my personal opinions. I've been an observer of communications through several wars, bombings and natural disasters over the last 12 years. And sometimes I've been very close to disasters, and worked as a volunteer. There have been several threads about turning off communications, taking action against communication providers perceived as supporting the enemy, or how the attackers used the freedom of communications against us. I propose, even if the attackers used our own communications, in fact by maintaining communication service we may have helped save more lives. Instead of cutting off communications, the best response is to keep as much operating as possible. Yes, its possible the terrorists might be using the circuit, but it is also possible the link is rescue effort or even a person trying to get a warning out. Dubbing the voice of the spokespeople associated with the terrorists may be a symbolic gesture. Cell phones and air phones allowed passengers call loved ones and authorities, but also kept the passengers informed about the other attacks in progress which may have changed what they did. Things might have been different if technical measures prevented passengers from using cell phones on airlines, or if cell phone providers had blocked those calls. Immediately after the attacks, communications once again helped victims and rescuers. Cell phones and e-mail were used before and after the towers collapsed. Rescue efforts are continuing by trying to locate beepers and cell phones of the victims. Network traffic went up, and many of the news sites had initial problems. Sites like Google, Yahoo, and ISPs mirrored information from the major news sites on local web sites. Although it may be a technical violation of the DMCA, several people simulcasted radio, television, even close captioning over the net. Although we'd like to think the government has better communications links such as NAWAS, in practice the commercial communications links carry most of the information and informed the public and even public officials. One of the problems with government communications, is no one has enough clearance to know the whole story, so the public communication networks often serve as the primary information source even within government. Its not a coincidence that every Emergency Operations Center watches the commercial news networks. The USA has maintained communication links with Cuba, USSR, even Hitler (invoking Godwin's law) through both cold and hot wars. I'm sure some people will say this is somehow different. But a hundred years of electronic communications, and a thousand years of communications has shown in almost every case the country which seal itself off from communications with the outside world has eventually destroyed itself. Propaganda may be a concern, but history shows its hard to fool all the people all the time. Propaganda works best when there isn't an alternative source of truthful information. One reason why countries acting as hosts for terrorists try to limit communications is outside information sources makes their internal propaganda less effective.

This is from the inverview with the spokesman of well-known terrorist Shamil Basaev, known for personally taking hostage hundreds of patients in a hospital, among other things (the spokesman is Movladi Udugov, the guy who threatened to drop an airplane on Kremlin). http://www.kavkaz.org/english/news/2001/09/14/news4.htm Hosted by XO Communications - do not bother them, i already alerted their staff. Guys, why should a North American provider give a place for this propaganda? Call FBI, have them trace the connections of whoever pays for that site. [If you decide to read the entire article - the "so-called peacemaker" Boris Nemtsov mentioned there is a prominent pro-Western politican in Russia, and (used to be, changed his mind after WTC attack) a leading proponent of negotiations with Chechen militants. A shining illustration of what you get for trying to negotiate with terrorists.] Please, if you host websites, take a closer look at what you are hosting; you may help to find leads for the investigation. --vadim

Sprint/Sprint PCS Network Status
by Sean Donelan 15 Sep '01

15 Sep '01

Since Sprint usually makes a statement only after they've fixed a failure, I'm guessing something else happened this morning, and is now fixed. Anyone with information about what Sprint fixed? Sprint/Sprint PCS Network Status SEPTEMBER 15, 2001 KANSAS CITY, MO. As of noon, CDT today, Sprint wireline switching facilities that support Sprint's telecommunications network are stable and processing voice and data traffic normally. In addition, Sprint PCS reports that progress is being made to restore wireless phone service to customers throughout the greater New York City metropolitan area. Four Sprint PCS cell sites remain out of service in the immediate disaster area. Many other sites across Manhattan are still without service primarily due to the loss of their landline connection provided to Sprint PCS by other telecom carriers. Service for most Sprint long distance and wireless customers remains normal across the rest of the United States. Some wireline voice and data customer sites in New York remain without service, again due to the loss of their landline connection provided to Sprint by other telecom carriers. Sprint associates continue to work with other telecom companies and government officials to restore full service as soon as possible.

FCC: Do anything you can do to help

I expect all LEC, CLECs, wireline, wireless, carrier, non-carrier, traditional, next-generation, tier 1, tier 2, etc are willing and working to relocate and re-route anyone with service, systems, etc disrupted or destroyed by Tuesday's attacks. The FCC has told carriers "Do anything you can do to help." I would apply the same statement to non-regulated ISPs and alternative communication providers. If you need special assistance in getting circuits re-routed, or installed in a new location, talk to your provider. Consider many of the alternative providers, which had a lot of excess capacity before Tuesday's attack. For example, there are reports of several former dot-COM property management companies offering space in buildings previously occupied by dot-COM companies which went out of business earlier this summer.

I've tracked down a couple of particularly weird problems that turned out to be triggered by cruft that was inherited from the initial bootflash image. Now upgrading the bootflash is the first thing I do. Presuming you aren't running low on memory (show mem sum) or trying to push a ton of packets through it, I'd say this is likely a cutting-edge-code problem, not a platform problem, and a hardware upgrade might not do anything to help you. I don't know anyone who is (admits to?) using 12.2* in production. You say you need MSDP and SSM stuff that's only in this version; I don't know about source-specific multicast, but MSDP is supported in 12.0S... ---Rob

ACARS (was Re: An Idea)

This would probably be more expensive so would probably be > limited to larger aircraft. This capability has existed since the early 1980s. It is called ACARS, which stands for Aircraft Communications Addressing and Reporting System. I developed firmware for the Bendix system purchased by Delta, Piedmont and Northwest Orient in 1985. Those same systems (which sold for, if I recall correctly, about US$18,000) are in use today. Little, if any, of my other career work has had similar longevity: it is a (sobering) reminder of how long it takes to make improvements in commercial aviation. You can learn more about modernization efforts, including satellite, overseas, and encryption capabilities, by surfing over to www.arinc.com and searching on the keyword ACARS. I do not know whether the airlines are interested in using this to augment the cockpit voice recorder but it would make sense. Twenty years ago, the system was limited to 2400 baud and it was essentially used as a "time clock" for automating the process of tracking hourly air crew wages. The other two primary uses were to provide rapid turnaround on jet engine performance parameters (which reduced service costs), and to expedite bi-directional weather reporting (pilots could retrieve or file weather reports into an automated system). The aviation industry was fun to work in back then but more recently it has been no joy at all (the last project that I participated in was ETMS, which is a USA radar tracking network whose control room is in Kendall Square, Cambridge, MA): too much bureaucracy and too much money to get far too little done. It just doesn't seem hard to me to come up with a snazzy database system to keep track of 10,000 airplanes in real-time with data, audio, and video feeds. A dot-com could've done the equivalent task on a few tens of millions of VC money in the space of 3 years, whereas the US government manages to plunder $billions and waste decades. Pardon me for venting. But if someone wants to give it a try, perhaps for some country other than the USA, then I'll come join you on building a "real" aviation network. -rich

Randy, I truly doubt you understand the idea of war and protection of our citizens. The USA is not going to retaliate... It is answering a call of war - one that has been ongoing for many years. Unlike the Russians going into Afghanistan, our even the US going into South Viet Nam (or the French in your example), we have the skill to go up to the street bully, knock him out, knock the dust off our hands and walk away. It is not like it needs to be 20,000 troops driving into that country. Standing back and hoping it will go away because we want to be "peaceful" has NOT proven to work over the last ten years. > resist the cycle of violence and hate. I agree. But this action doesn't need to be attached the words violence and hate. It is better attributed to, enough is enough, and knock the bully out. Truly, that simple. Best regards to you Randy,
