a class C for each home? wha?
if we have true always on networks running into houses, why not just use a well defined DHCP implementation? there's a lot of nifty tricks one can do with that, and I'm sure that several appliances that might be "net enabled" would be needing bootp/dhcp/tftp type services anyway for one reason or another.
From all the experiences I have had, most businesses (especially ones establishing new networks) are all using RFC1918 private IP addressing. this works rather well considering most businesses also use some form or NAT, whether it be a DSL router or a large array of firewalls backing an OC-3.
that, and most network engineers would agree that using public IP addressing for your business systems isn't always a good idea! think about it!
that being said, several large providers have started rolling out IPv6, like Telstra in australia. I think MCI/WorldCom has moved to using it or at least testing it for their backbone, but it will be several years before we really see it rolled out on any kind of large scale.
As for me, IPv6 is kind of scary, since the last 48 bits of the 128bit address are your MAC, and I'm not particularly interested in people being able to track me down that specifically. somehow it just seems like a situation waiting to be exploited- perhaps it's time to start using the more expensive intel nic's that allow you to define your own MAC on them, for purposes of being sneaky:)
cat5 is not all that expensive, when you're buying on that level- I pick up 3~4 mile spools of cat5e from graybar for about 140 bucks. I can't imagine how much cheaper it is to buy it from a general contracting standpoint, but it must be quite a bit lower.
and cat5(6/7/etc) are standard specs, so calling it obsolete is kind of silly, when you think about it.
that being said, running some fibre strands to neighbourhoods and then running cat5e or cat6 to a house is not unreasonable by any means- making customers buy fibre nics is quite pointless, as well as non-backwards/forwards compatible. fibre standards aren't as nicely categorized as copper, for ethernet anyway.
Don't forget that if you have copper running into your house, you can't be fully TEMPEST-compliant:P
because shielding your house from EMI and Van Eck phreaking is that important... I read in one of winn schwartau's books that it's actually illegal for citizens to shield their houses or dwellings in such a fashion, does anyone know more on that?
OSPF is an interior gateway protocol (IGP), and is meant to be used internally for medium to large networks (NOBODY SHOULD BE USING RIP! ICKY! NO!)
BGP is an exterior gateway protocol (EGP), and is meant to be used as a routing protocol between internetworks (AS's, autonomous systems for OSPF networks, as well as BGP networks for that matter.)
it's kind of like the difference between astroturf and carpeting; each is meant for a different area of your house- the astroturf is outside, the carpet inside.
Of course you can run BGP on a 2600, but don't expect anyone to think you're sane if you're doing that for a customer/company that actually needs some kind of powerful routing ability.
at least use the 3600 w/ a RPS, so you have some power redundancy!
do you even think before you spout this kind of drivel?
You sound like one of those $12/hr daylabour tech monkeys that your so-called "gurus" like to hire for cleaning up messy wiring jobs, scrubbing floors, breaking down old equipment, etc.
Nobody is saying that greater productivity and the like are bad in any way! It's just important to balance these things with a bit of common sense about security. If you don't think about the security of your systems, who will?
As someone who spends a good portion of time dealing with "enterprise" NT systems, there aren't a whole lot of times when one *can* install service packs, do testing, etc. quite often, at least for me, I wait weeks to have a window of opportunity to do whatever it is that I'd like to do.
Now I realize that scheduled downtime and the like is good, and while I work towards achieving that, the reality is that the whole dot-com business space isn't run by seasoned administrators and IT managers. These people aren't always the most clueful with regards to sound information systems practices.
So, to a certain extent, there's two things- people don't always have the time to upgrade NT systems with potentially poor unstable code and then properly test it.
Also, like some other posters have said, there are lots of incompetent sysadmins out there. this falls in line with the whole "new IT infrastructure/startup/low budget/whatever" situation.
Sometimes making shortcuts to try to save money hurts you (or your customers) in the long run. one would like to hope that we'll all learn from this, but my money is against that happening. This isn't the first problem of that sort, nor will it be the last...
For those of us responsible for managing large networks that *ARE NOT* on the public internet (I know that comes as a shock to all you college students out there) having someone else monitor our systems is bad for two reasons.
1.) it's not us doing the monitoring. this breaks most security policies within any company of a large enough size, as well as just being bad form all around.
2.) as I mentioned, when you have arrays of firewalls between you and the net, it's really quite pointless to ask someone to monitor your systems, now isn't it?
When are all you little kids going to start understanding the world doesn't revolve around your bandwidth wasting napster using asses? it disgusts me.
most of your name suggestions would still be equally problematic, as his complaint revolved around the use of the SSH name in the product title.
I also don't think most people would really want an open implementation of SSH to be called "ASS".
Realistically, regardless of how all the opensource wonks on here act, he has a fully legitimate claim to the name and has been much more forthright with his request than many other companies would have been.
Besides, I'm sure someone could come up with a name that is cooler anyhow. who thought up the name for blowfish? where are they in this discussion?
and with regards to SSHv1, there are many devices that have SSHv1 implemented in hardware without support for SSHv2. I'll take a SSHv1 connection to a router over a telnet session any day, how about you?
Jon Katz and film reviews.

'Snatch'
·
· Score: 1
I've personally noticed that most of Jon's reviews don't match up with my perception of the film (after I've seen it.) He also seems to have this uncanny knack of posting a review for the film the day I plan to see it, which is really starting to freak me out.
Seriously though, I'm not sure what Jon expects to get out of films- I'd like to know what he goes into the theatre expecting to see. I go to most movies that come out (a sad addiction) typically with rather low expectations, and sometimes I am rewarded by having a better-than-average experience seeing it.
With regards to "snatch", I thought Lock, Stock, and Two Smoking Barrels was a fascinating and entertaining flick; I've also been happy with the work that Brad Pitt has been doing lately, taking strange character roles etc (Fight Club? 12 Monkeys?) so I expect it to be an interesting movie all around.
Maybe it just has something to do with watching movies without a haze of pretension skewing my vision of everything. my two cents.
please moderate this up.

I'm not sure how many of you have actually worked with VoIP, but the maximum latency you can have without the conversation turning into a CB radio-style transmission is about 200ms. I believe 250ms is the maximum, but at that point it starts to get a little hazy. Mind you, I'm talking 200ms round trip, so you're looking at 100ms or so maximum to get there. when is the last time you transferred something around the world, on a TCP/IP public network, in under 100ms? it rarely happens, especially when it is between 2 different end points (i.e. end-users like you and I.)
VoIP is a fantastic technology, and it's great to work with. within an office setting, or enterprise-wide, it's a great solution. However, it's not really suited for someone's dorm room, or for your home computer, etc. It helps to have fibre only a hop or two up your private network, or to have something like a cable network (ala MediaOne, RoadRunner, AT&T etc.) You really just have to have that low latency.
my 2 cents. You guys have motivated me to look more closely at my cisco VoIP books today at work:)
It's not a lunch break- I don't feel like driving 30 miles through traffic each way. I think you missed the point of my argument (which was, amongst others, that physical voting sucks!)
My boss doesn't really care. I could take the whole day off to vote if i wanted. I just don't like waiting that damn long for old biddies to figure out what the hell they are doing.
for that matter, it's not crap. the candidates are crap. I'm going to vote for local elections and nothing else, maybe I'll throw my vote away on nader. ask me if i really give a damn about who's leading the corporate state... i don't.
I stopped by the local library this morning and there was absolutely no one there. however it was not the correct voting precinct. so off I drive to the fire hall across town...
I get within a quarter mile and there are cars everywhere. I park and walk a long distance to get there and when I get inside there are maybe 300+ people in line. mind you I also have to wait in a 50+ person line to register to vote, and then another huge line to actually vote? I don't have 3 hours to kill like that!
So I walked out. the old lady by the door said "you're not going to wait?" with an incredulous tone. I told her that I didn't have that kind of time to waste, since I work for a living.
I'd like to know why we can't work towards having digital/electonic voting. I personally feel that enough security measures could be taken to ensure the viability of this, and I personally can attest that it would make it so much easier to vote! I know there are so many arguments about this, about how it hurts the poor who don't have computer access etc. but tell me this- how many poor people who get paid hourly have the time to leave work and drive home just to wait 2 hours to vote? very few, I'll bet.
Whereas if they mailed out some kind of single-use key to all elible voters... you could use it either at a traditional voting booth, or use it via some kind of heavily encrypted/hardened site over the internet. I'm not sure how it would work but I know we'd see a MUCH larger percentage of 18-24 year olds vote! we're talking 80% non voters here, and falling into that age group I think I understand why they don't- it's just too much of a pain in the ass!
That's just my two cents- I'm going to try and go vote when I get off work, but since I'm putting in another 12 hour day today (like all of you other tech slave labourers out there) I don't know if it will happen.
Attempted Civic Responsibility = Pain in the butt, and a longer work day... bah!
and another note- if you arm yourself to kill your own babies, wouldn't it just be better if you shot yourself in the stomach to get rid of them? since that's what you're defending anyway?
I thank god that I'm not one of your children. would you tell them one morning that you are tired of them leeching off you like a tapeworm and just throw them in the garbage?
human life is not disposable, especially the innocent. for someone who gets on such a tangent about others being so vile, your disgusting view on human life is absolutely horrific.
I thank you again for making me realize why I don't vote for people who think like you.
Was it Paine or Franklin that said he who is willing to give up liberty for security should have neither?
It's something like that anyway- point being, if you're willing to give up all of your rights one by one to buy added "security" from the State, you don't deserve to have them in the first place.
People died to give you this freedom. don't throw it away!
of course, you're presuming that the majority of people care much about apple's code. while niche software like apple's is interesting, mainstream stuff like microsoft permeates all corners of computing use.

For that matter, I really get sick of things with the e- prefix; so while email predates all these stupid e-things, why feed the fire more...
I suppose however that if you are a publication that makes it's money off annoying people with your trendy representations of the wired world, then you probably *SHOULD* use "e-mail".
