You will need some form of circuit isolation for the powered transeivers on each end. A really good power bar.. or UPS will probably do it for you. And you should plug it into a completly different electrical circuit from the rest of your network, if you can..:)
Fiber.... Get a two fiber to 10baseT, 10Base5, 10Basew2, 100BaseT or 1000BaseT transeivers. Lightining doesn't really impact fiber. Then use fiber for the long haul...
OR
you can buy 4 Fiber transeivers and a two, 1 meter fiber patch cords and put 2 transeivers on either end and use it kind of like a optical isolator. then if lightining hits the transport copper you, at most lose 2 transeivers, and the networks on either end are ok. Then all you should have to do is replace the 2 transeivers on either end.
I sold my Modded Xbox about a year ago. I never really used it to pirate any games. Although I did extend my use of a few rented ones for a couple of days. I sold it and bought a new Xbox that has not, and most likely, will not be Modded. The guy I sold it to knows there's a mod chip in there.. thinks it's great, but wouldn't know how to use it if his life depended on it.
I personally think that all the time waisted on trying to install the mod chip, keep the software current and then to copy and store the games is alot more trouble then just buying the 2 or 4 titles a year I really want and renting the rest.
Isn't part of the problem with the companies that distribute the channels to the cable co's?? Don't they say "if you want the golf channel you have to take the home shopping network and the watch paint dry channel aswell" or something like that?
Cable is a broadcast medium.. that means everyone on a node/laser group gets the same data.. in both directions(if you care about Cable Modems). You can not, without doing a COMPLETE rebuild of the cable architecture, do what you are suggesting.
I highly doubt they could make it profitable anyways.. as they would have to put in some sort of BOX that would allow them to strip the channels appart, at the local/street level, and then recombine them for each house and from there have a single wire running to the house. Sounds like a very expensive proposition.
Isn't a form of product activation the main reason that DivX (the DVD format..not the A/V alog.) went under?
My point is.. that with other choices in the market.. I don't think people are going to choose a product where they are being treated like a criminal and have to check in with the PO every time they upgrade.. or worse.
I finally decided to get a LIC last year. I figure that I make enough money now that I should give something back to the people who wrote the software I've been using for years. Not to mention I couldn't really hide behind the "I'm just a poor student" mantra any more.
What gets me is that the same people who were bitching about tech workers putting them over a barrel in '99,'00 and '01 are the same people who are now putting their workers over the barrel.
What can you do?? You can't quit your job cause you might not get another for a long time. You can't be a pain in the ass.. cause there are 30 other people who are unemployeed looking for your job. MGMT know's they have their workers by the balls.. and now they're going to apply pressure..:(
Isn't life just so totally unfair?? I mean.. treating ISPs in Africa and other countries the way that every other ISP is treated.... How dare they. Obviously you bend over and help pay for the internet usage in that country.
Talk about stupid.. the only time a ISP gets any sort of discount on traffic is if they are HUGE and can get some sort of peering arrangment with another HUGE ISP.. and even then each ISP is responsible for transport to and from the peering point.
INAL: If they help you to secure your machine they could possible be held responsible if your machine gets owned. By not making any recommendations they remove themselves from the equation and elemenate any possible lawsuits.
You've got to be joking.. I'm sure they have better things to do with there time then to analyse the types of data flowing across their network. That is just dumb. If you cause a problem then they may look into your traffic situation.. but I'm sure for the most part they don't care, and couldn't do much about it if they did.
Ok.. so whats wrong with wanting other companyies to pay for access to a high speed network?? Currently UUNet (as a example) requires non-tier 1 providers to pay for peering access. How is this any different? I'm sure many other Tier 1 providers do the same thing.
Printed manuals are most certianly alive.. While the online documentation is usualy more current.. when I am working a problem there is nothing better then to be able to flip threw a book and find the answer or read up on it.. usually the online books/docs have crappy search capabilities.. they're browsing software (even Acrobat) is just ok. which usually means I can find what I want from card copy much faster and with more precision.. *shrug*
The point of his msg, has little to do with Id's policy or what they're going to do. Alot of ppl are whining about why they don't distribute a hybrid CD, or why they can't just use some other method for determining the number of linux version that have been sold. The people that need to be influenced are the retailers, and OTHER game publishers. The publishers need to be aware that there is a market for Linux games/software, and the retailers need to be aware of the fact that by selling Linux software their number of units sold will increase. They don't care about hybrid CD's or if there is 50 CD's in the case.. all they are concerned with is.. there cost, and there markup. Also Hybrid CD's are only good if you don't have anywhere near a full CD of data for one system alone. Just my $0.02....
Back in the 60-early 80's, ppl were scared that someone was going to push the button and effectivly end the world. Now, it doesn't seem very likely that anyone will touch off a full blow assault with Nuc's. However, what is more likely to happen is a terrorist group, or small nation using portable Nuc's to cripple another countries economy, and/or military powers. Sure ABM's can shoot down a Ballistic Missle, but they don't stop someone from placing a Man portable Nuc in the middle of NY city. Just a thought.
If I recall from reading the spec a while ago.. using MAC's is just one suggested method of providing ip's in the IPV6 world. Considering that you can, in a number of cases, change your devices MAC address, it hardly seems like a issue anyways. Lord_Rion
Using CT, how easy or otherwise is it to bring own or attack vital systems?
Define a vital system. If you define a vital system as a hospital, bank, telephone (911), police and C3I, there are much easier and more effective ways then using computers. In most cases the "critical systems" within these orginizations are isolated and have few external components. Sure you can crash the St. Lukes web page, but I doubt it would be nearly that simple to get patient data. That being said, if you can get enough information about how the place, company, or group, operates and does business you can usualy find a way in. Once in you can work on editing, deleteing or destroying data and/or systems. All that being said, I think there are easier ways to disable vital systems, blow up a church will clog up a large number of services, or destroying a power station, relay station, or transmission lines will cut out large amounts of power to an area and are hardly ever guarded or monitored. No skills needed for those.
What sort of skills would be needed to do so, and are they common/teachable?
They aren't common skills, and I'm not sure if they can be taught. To hack/crack you have to have that kind of mind set. You have to be able to think of a problem and then logicaly break it down into steps, or sub problems, and attack those pieces. You often have to be a bit rebelious, and try and do those things which they say can't be done.
Commercial-off-the-shelf software: can it really do CT?
If you consider DoS attacks as CT, sure in some cases.. but mostly no. There is no Commerical off the shelf (CoS) CT kit. Usualy the vital systems are one offs or specialized enough that the vast majority of the people out there won't have seen them, or their design.
Which systems are actually attackable?
Once again, I don't know what you mean by vital systems. Military levl C3I is usually pretty anal about security, so I would say it's not easily attackable from the outside. Most civilian vital systems are fairly vunerable in that they have more access points and fewer physical safeguards. However, anything is attackable from the inside.
Can a recovery be made from such attacks?
Depends on the attack. I've written programs to replace dump and tar that corrupt one random byte in a random amount of data so that even though the backups look good the data is bad. And there is no way of telling unless you recover the whole tape and find the one or two data files that have changed and go threw them with a microscope. Now imagine the problems if someone had 10 weeks of backups each with different bits of bad data and the system got totaly flushed, there would be no way to know which data was good and which wasn't. SO to make a long story short, if done properly, and if they know enough about the system they are attacking, you may not be able to recover from it.
Is it likely to improve/get worse?
As the people who make the decisions get more out of touch with the actualy technology and skill sets of the job the worse it will get.
What sort of preventitive work would you recommend them to carry out?
Train people in security. Have someone on site who's job is security. Make them responsible for any "issues" that come up in regards to security. Force them to notify the decsion makers if there is a breach, or suspected breach. Then give them the budget to make it happen. Not cheap, not quick, but it will work.
Cable modems are no more or less secure then dsl. Most head ends have the ability to block peer to peer communications, and encrypt data coming and going to the cable modems. Most people's fears about cable modems are driven by there ignorance and mis-information.
My understanding (being canadian) is that the US gov't wants to limit the use of strong crypto to protect the american people and their way of life. Assuming I am correct in that assumption.. even if they pass this law.. what is going to stop criminals from using strong crypto anyways?? If they are doing illegal stuff anyways.. what is one more thing like using strong crypto? Makes little sense to me.. but then again I'm canadian as I said before.
Don't get me wrong.. I like cable modem service.. and I think it's a much better technology then xDSL or ISDN (for home use), despite it's shortcommings. I just think Cable Co's need to work on there backend service more.. be more reliable I guess is what I'm saying..:) Lord_rion

I'm really sorry to see Valve go to this model. I was really looking forward to playing HL2. However, now I highly doubt I'll buy it. :(
