The solution is simple, proven, and works immediately (hours or days): a significant group of managers (from firms on this list) agree and announce that on a certain date and time, all mail will be bounced back to IP addresses with a recent record of emitting spam, viruses, trojans etc. (There are publicly available lists.) This has been done in limited areas and it works immediately to force the negligent providers to shut off all customers with dangerous boxes.

I believe this has resulted in a few lawsuits from companies such as Gator, which take offense to their "adware" being removed by the ISP... Of course, 99% of the time it's installed via a "click-wrap" EULA for some 3rd party software such as Kazaa. It would be just as easy to uninstall it via another EULA for the ISP's custom dialup/PPPoE/PPPoATM/whatever client. :-) > e.

For the coming fiscal year, the House Committee-recommended funding creates a huge shortfall, and the Senate Committee's recommendation implies no support for space weather service at all this year. Possibly a new service would be established elsewhere in the government, but that is uncertain at this point. We thought you would like to know. Ernest Hildner and the staff of SEC ======================================================================== U.S. SPACE WEATHER SERVICE IN DEEP TROUBLE SUMMARY For Fiscal Year 2004, starting October 1, 2003, the House Appropriations Bill for Commerce, Justice, and State continues Space Environment Center's funding at $5.2 M (a reduction of 40% below the FY02 level). Worse, the FY04 Senate Appropriations Bill zeroes Space Environment Center and all space weather in NOAA, so services, data and observations, and archiving would all disappear if the final appropriation is at the Senate level. At the House funding level, starting October 1 SEC will rapidly lose about half its staff, negatively affecting its ability to serve the Nation with operational products, data collection, and R&D. Unless the appropriation level for Space Environment Center is restored to the level of the President's FY04 Budget Request, $8.3 million, the Nation's civilian space weather service is in trouble. At the President's requested funding level, Space Environment Center can almost return to FY02 level of services, data, and R&D. BACKGROUND NOAA's Space Environment Center in Boulder, Colorado, provides a range of services to the Nation related to space weather phenomena. Among other activities, the Center is the unique provider of real-time monitoring and forecasting of solar and geophysical events, it conducts research in solar-terrestrial physics, and it develops techniques for forecasting solar and geophysical disturbances. That is, Space Environment Center is the Nation's space weather service, monitoring and predicting conditions in space, much as the National Weather Service does for meteorological weather. SEC jointly operates the Space Weather Operations Center with the U.S. Air Force and serves as the national and world warning center for disturbances that can affect people and equipment working in the space environment. It is the government's official source for alerts and warnings of disturbances. Customers include DoD, NASA, FAA, airlines, operators of electric power grids, communicators, satellite operators, the National Space Weather Program, and commercial providers of value-added space weather services. Partnering with researchers funded by NSF, NASA, and the DoD, Space Environment Center is the place where much of the nation's $100s of millions annual investment in the National Space Weather Program and in space physics research is applied for the benefit of commerce, defense, NASA spaceflight, and individual taxpayers. SEC's appropriation lines can be found in the Department of Commerce, National Oceanic and Atmospheric Administration (NOAA), Office of Oceanic and Atmospheric Research portion of the Budget. In the omnibus appropriations Bill for FY 2003, the SEC received a severe cut to its budget of about 40%, with no explanation for the reduction. One-time funding additions have kept SEC afloat in FY2003. The President's Budget request is $8.3 million for SEC in FY2004 (an amount consistent with its past budgetary levels), but the House Commerce-Justice-State Appropriations Committee provides only $5.2 million, or roughly 40% less than the amount necessary to maintain SEC at its current operational effectiveness. Again for FY04, no explanatory text was included in the Committee Report to explain this reduction, and it far exceeds the 18 % reduction below request meted out to NOAA Research overall and the 1% reduction to National Weather Service's request. The Bill has not yet been acted upon by the full House. The Senate Appropriations Committee explains its termination of space weather in NOAA in the Report accompanying its Commerce-Justice-State Bill as follows. The full text of the Senate Report may be found at http://thomas.loc.gov/cgi-bin/cpquery/T?&report=sr144&dbname=cp108&amp Solar observation. - The "Atmospheric" in NOAA does not extend to the astral. Absolutely no funds are provided for solar observation. Such activities are rightly the bailiwick of the National Aeronautics and Space Administration and the Air Force. Needless to say, there is no evidence to suggest that NASA and the Air Force agree that one or the other, or both, should operate the Nation's civilian space weather service. CONCLUSION Unless SEC's appropriation level is increased in Conference, the best outlook is that Space Environment Center shrinks to less than half its capability (House mark), and the worst is that space weather will disappear from NOAA (Senate mark). In this case, the Nation's space weather service will have to be reconstituted in some other agency, at greater cost and lesser capability, to meet the Nation's needs. ************************************************** Ernest Hildner Director, Space Environment Center Tel: 303-497-3311 Manager, NOAA Space Weather Program Fax: 303 497-3645 325 Broadway, Boulder, CO 80305 www.sec.noaa.gov ------------- End Forwarded Message ------------- ------------------------------------------------------------------- Gregory Hicks | Principal Systems Engineer Cadence Design Systems | Direct: 408.576.3609 555 River Oaks Pkwy M/S 6B1 | Fax: 408.894.3400 San Jose, CA 95134 | Internet: ghicks(a)cadence.com "The trouble with doing anything right the first time is that nobody appreciates how difficult it was."

Rx and Tx on a single SMF strand for MANs?
by Eric Kuhnke 24 Oct '03

24 Oct '03

Would anyone like to contribute their favorite solution for doing both Rx and Tx over a single fiber, in MAN environments? http://www.imcnetworks.com/products/minimc.asp I've found that unit, but I'm hoping to find some alternatives... Is there anything that will do 1000Mb over a single fiber?

NOAA warning for rf communications
by Rodney Joffe 24 Oct '03

24 Oct '03

I'm surprised that there has been no warning or discussion on NANOG... There is a high likelihood that things like 802.11, licensed and unlicensed microwave links, and certainly satellite links will sustain interference over the next few days. I assume that everyone on the list is both aware, and prepared ;-) Oh, perhaps an alternative to paging or cellphone notifications to support folks is a good idea ;-) http://www.astrobiology.com/news/viewpr.html?pid=12850 The NOAA links seem saturated... http://www.sec.noaa.gov/ -- Rodney Joffe CenterGate Research Group, LLC. http://www.centergate.com "Technology so advanced, even we don't understand it!"(R)

AS num and route flaps
by Rodney Joffe 24 Oct '03

24 Oct '03

Is anyone aware of any relationship between AS numbers and route dampening? Are there any situations, or knobs to be tweaked, that can result in an AS being dampened due to flaps, rather than only ip addresses and prefixes and meds coming into play? I'm working on a tech draft for IPv4 anycast in DNS, and in the hallways in Chicago there was some peripheral discussion about the problems that would occur with route dampening including a statement that if the various anycast addresses were in the same AS and only one of the nets flapped, they would all be affected if "someone networks" dampened the AS. For some reason no-one in the assembled pack questioned the veracity of this statement at the time. Granted, it was late in the night even for NANOG, but in the cold light of day I can't see any relationship. So I would appreciate any input in case someone has found a reason and method to involve AS numbers in dampening (and specifically related to dampening - I am not examining other factors like fat fingering, or filtering issues based on AS, at this stage). Many thanks... -- Rodney Joffe CenterGate Research Group, LLC. http://www.centergate.com "Technology so advanced, even we don't understand it!"(SM)
