Public thanks to UUNet security
by Mark Radabaugh 30 Dec '02

30 Dec '02

Since the good things so rarely get mentioned... I would like to publicly thank UUNet's network operations for dealing with a DOS attack quickly and efficiently yesterday. I am happy to say it only required one phone call of less than 15 minutes to get the appropriate filtering in place. Mark Radabaugh Amplex (419) 720-3635

DC power versus AC power
by ip dude 29 Dec '02

29 Dec '02

Hello NANOG group. I am trying to make a case for using DC power supplies versus AC power supplies for typical IP networking equipment. Is there any published whitepapers detailing this subject? Do you have any suggestions to aide my argument? _____________________________________________________________ Get your own free Ranch eMail and Classified Ads at http://cattletoday.com _____________________________________________________________ Select your own custom email address for FREE!

On the other hand, video monitors like sine waves, and > they may not get along with DC inverters/rectifiers (or even portable > AC no-breaks, which usually generates AC from DC). Sure. And not to get into a contest here, but it all depends on how bad the approximation is and what gear it is we're talking about. It's just something to consider and research, and include in the decision. Clean power plants (and that's got nothing to do with green ;) is always a good thing. Doesn't have to be perfect, just close enough for <insert operational criteria here>.

RE: Hardened dishes, was Guam

Wow, does that take me back :) There used to be very similar arrays at RAF Chicksands and other assorted Air Force comm detachments around the Midlands area in the UK. Most of these were relocated/abandoned in the mid to late 80's though. I was stationed at RAF Croughton, (Wideband/Satcom) and we had similar dishes there. My primary responsibiity was the 60-ton-dish satcom facility, where we provided a majority of .eu military communications out of Europe to CONUS. I unfortunately throughout the years managed to lose most of my pics of the base and dish farms, (too many moves across country, etc.) Might anyone have photos (or know of anywhere on the internet) where I can download some of those again? Thanks, and thanks for the pic..
