Mostly right, except for the fact that there are no rules where lightning is concerned. Its not unusual for lighting to do truly mind boggling stuff, frying stuff far away while sparing things close. Not all damage is done by the strike itself, some is done by induced currents (lightning is pulsed DC) in long cable runs, and surges FROM (not TO) ground.

Out of curiosity, did these things happen in Alaska? I wonder if there might be added phenomena or properties of lightening in areas where geomagnetic and solar effects are sometimes stronger (sometimes much stronger).

Yes, during one of exactly 4 occurrences of Lightning I've ever seen in Juneau in 30 years. Closely ringed by mountains, Juneau seldom ever gets lightning. Solar effects happen much higher than lightning if my rudimentry understanding of the atmospheric model does not fail me. -- ----------JSA--------- There are 10 kinds of people in this world, those that can read binary and those that can't. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I just lost an ethernet port and several ports of my wired router to a lightning strike on Long Island. Does anybody know where I can get a new (or used, working) Linksys BEFSX41. Everybody wants to sell you an RF router, which I don't want. The Linksys was an excellent firewall, but I think only one poprt is still operative.

Good, now remember that if it (a connection) comes into your computer from the outside world, it too must be surge protected.

Ask any electrical engineer. They will tell you the same thing. There is no such thing as protection from lightning. Something that just jumped 10,000 feet out the sky melted your TV, set the utility poll on fire, and has your cat puffed up to the size of a panda bear, will not have a problem jumping no stinkin surge protector. -- ----------JSA--------- There are 10 kinds of people in this world, those that can read binary and those that can't. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Quite so. Those power bar suppressors, at best, will remove large noise spikes from the power line, assuming they've got a good, solid ground connection. The U-ground is not sufficient. Everything coming into your house (power, cable TV, phone etc.) is supposed to be connected to a good ground (usually water pipe) at a common point. The purpose of having one and only one ground point is to prevent loops that will often make the problem worse. The author is wrong. The National Electrical Code specifies that the

I don't know about where you live, but around here (Canada) the water supply line from the street is commonly used for grounding. Cable TV & telephone lines are supposed to have properly grounded surge suppressors too.

Someone gave a direct order to move this conversation to Off-topic. Be that as it may... Doug is right, the NATIONAL electrical code has outlawed waterpipe ground for over 10 years. There is just too much PVC pipe segments being used these days to trust a pipe. (Actually outlawed is the wrong word, it just does not recognize or allow pipe as the principal or only ground). I capitalized NATIONAL because, James, your country MAY have different standards, but I doubt it because I believe Canada as well as the US are participants in the international residential electrical/plumbing code committees. Look at NEW construction to know for sure. -- ----------JSA--------- There are 10 kinds of people in this world, those that can read binary and those that can't. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

That's why I personally drove an 8 foot 1/2 inch diameter copper rod into the ground with a 2 pound sledge directly below my server install to provide an immediate solid ground to everything that enters the server closet..... It is the best you can do, but... a good lightning strike will still melt everything attached like it was made out of butter. But, it still provides much better ground protection than a ground attached 100' away. You can protect against some of the strikes all of the time but not even come close to protecting against all of the strikes even some of the time...... -- David C. Rankin, J.D., P.E.

It would seem you've just told the world where they can go to steal a very good-sized chunk of copper. And people have been doing things like ripping up empty homes and taking apart street-lighting to get copper, so I don't think it's so far-fetched...

But he didn't tell the copper thieves anything they didn't already know, since every building has at least one of these rods already. It took a sledge hammer to get it in the ground and it will take a great deal of time and effort to get it out. But copper thieves are getting pretty aggressive. Not smarter, mind you.... http://baudrillardsbastard.blogspot.com/2007/07/sign-of-times-hardtimes-hit-...

I guess that you are very lucky.

I guess this is addressed to Duaine and Laura, but as you have seen, I have a similar problem. The MOBO problem has not been solved. The ethernet port is blown, and I can only access part of the BIOS, so it is unlikely that I can plug in an ethernet board and have it recognized.

If you have some spare NIC, just plug it in and see what happens. It can't be worse than it is. -- Regards, Rajko http://en.opensuse.org/Portal needs helpful hands. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
