Depends what options are turned on in the blocking software. SmartFilter, istr, has an option you can flip to stop IP addresses too. (And it's not very useful for ###.sourceforge.net which needs the Host: header).
Pity the vendors think so highly of their own software that they aren't prepared to supply unencrypted lists for use with other software. It would be no problem for them to salt any unencrypted lists they sell, so they could easily determine the source of any lists which end up warez'ed...
Then again, I'm not sure the encryption is going to be of vastly higher quality than the blocklists, so it's possibly not going to be too difficult to move across anyway.
Yeah: see, there is a use for filters. "You're not allowed to access this site because it contains software bundled with bonzibuddy, aureate, comet cursor or something else that'll fsck off the BOFH".
Maybe with an optional "Try cleanclients instead" if the blocked site is for p2p software.:p
So, do you block all HTTPS too, then? (Or do you just crack it open and pre-install a cert on clients so you can re-encrypt so most users won't know...)
Just set those sites to redirect to a locally hosted page. Background sounds are good too
If it's in a lab or something, put a speaker on the squid machine, make the 'blocked' page a CGI script and have it work out who accessed the page, and have it use some text-to-speech program...gets around the problem of people not having their speakers turned up loud!
If you've got a large list of sites to block, you should find CPU use should drop and page access time should be much faster by putting the blocklists into squidguard rather than in squid ACLs.
I'm sure there are people in Korea who don't read English who've received reams of spam from the USA over the years...
You can drop quite quite a lot of it by filtering on =ks5601 etc. in subject lines.
Or you could bind to >1024, and redirect the packets from the lower port. (Not sure how to do this with Linux, but with ipfw on FBSD you can 'add ## fwd 127.1,8080 tcp from any to me 80').
There's some nice things you can do with non-line-of-sight around 3.5GHz if you can get the power output high enough (often not possible on the lower power class-licensed systems available for use in the 2.4GHz band). And having exclusive access to a band gives a lot of freedom from interference that you just have to accept in 2.4GHz.
Right now, if I buy a book I can quite happily rip the cover off and even re-bind it with all the pages in the wrong order if I want, it's my book.
Yes, though if you do that (certainly in the UK, not sure about other countries) you're not allowed to sell it again. (A book without an original cover may have had the cover returned in lieu of the complete book for a refund).
Yes, it has stopped, along with texts from anybody using MTN to run a legitimate SMS list to people who want to receive them, also texts from ICQ, texts from friends on Swisscom, MTN, Vodafone Australia and Telstra. And yet I still have been voice-spammed by companies who bought my number from Orange, so they're not exactly anti-spam, just anti-spam-they-don't-make-any-money-from.
Where I live, which I guess might not be the norm for the rest of the country, the speed cameras are actually positioned in places where accidents are likely - sure, everyone speeds up straight afterwards, but usually that doesn't matter too much. For example, right by a petrol station entrance with poor visibility, and by the exit from a group of buildings onto a fairly busy road.
But don't get me started on the stupid 20mph limits which make everyone change down in gear and have more acceleration than they're used to handling, not to mention the fact they're spending more time watching the speedo than the road...
I guess I did imply to some extent that GPS was doing more it is. And I guess it's possible to have the device simply record costs, and only transmit total cost at the end of the month/year/quarter/whatever. But that would just make my point about hackability even more of a big deal.
Well, chances are that it'll be public-key crypto, and will either record valid position information, no position information, or junk which is not correctly formatted and/or is unlikely to agree with the backup mechanisms (like, the odometer). If the info is valid, you get taxed. Presumably there'd be an acceptable margin for areas with no-coverage (possibly tied in with the positions of sats in the area last logged for validation) and if it's too high, it'd get treated the same way as garbage data - i.e. as an attempt to evade taxes. Good crypto on smartcards is definitely not outside the realms of possibility (afaik NDS videoguard used on sky digital is still unbroken, and the cards used for this system could be a lot more varied than something which has to decrypt broadcast video).
I assume they mean they only store a one-way hash of the plate data. That could in theory be used to track someone, but as there are only 36^4 unique "tags" the feasibility would be *somewhat* limited.
Of course 'figure' is undefined, so it could mean a lot more than [A-Z0-9]. They also say about taking 4 centre digits - I think that was written before we changed number plates, 4 centre digits would not be very useful on newer cars (two cars bought from the same dealer would have quite a high probability of matching - and they would naturally be in the same area, quite possibly at the same company).
I would be very surprised if they would put in a national system of this kind that is not fairly easily reprogrammable, particularly bearing in mind the fact that conceivably the government might have use for and be willing to pay for access to full number-plate details at some point in time..
And of course two boxes in close proximity could be using different algorithms to create tags, which combined could get a pretty good idea of the full plate. (okay, put that one in the 'unlikely but possible' category if you like...)
That's quite a bargain compared to the Severn Bridge...cunningly priced so that it's probably just a little bit cheaper than the petrol would cost if you want to go to S.Wales via the midlands.
But I thought they wanted to make all the speed cameras visible to make sure that people slow down...perhaps they should have all the GPS satellites painted day-glo yellow and red stripes?
In some UK cities you can already change the traffic lights by using a little device which is attached to some buses. And where I live there are quite a lot of traffic lights with antennas on them, presumably to allow them to be changed manually from a control room to help relieve congestion if it's seen on the cams.
On the BBC report on earlier, they said that they'd scrap the 'tax disc' (road fund license) if they do this (saving ~ £150/year). Though that's actually a bit of a downer for people with very old vehicles (who currently are given discs for free from when the last tory government wanted to make it cheaper for owners of classic cars, but also made it cheaper for travellers and owners of very old bangers etc), since they'll have to pay more if this comes in.
C'mon, do people here really think that you can be *tracked* by GPS? It's a one-way signal. The receiver in the car does all the tracking, not GPS. But I don't quite understand how GPS helps all that much, since there still needs to be a way to determine how busy the road is.
But, that has already been solved. UK motorists have already been tracked for years across large parts of the road network. Why worry about potential invasion of privacy when it has already been invaded by a private company? (they have operations in USA too).

Even without goatse.cx, slashdot on -1 should probably be blocked as porn. Not too sure if the robots know how to click buttons yet though..

You could just use CGIProxy, with the script suitably renamed of course.

^C, ^V is fine. What I don't like is the stupid fscking rightclick-copy which you are sometimes forced to do when ^C fails.

You mean, like 'CERT advisory'.....bug in .....OpenBSD: not vulnerable.
I bet the support for PSD in IrfanView wasn't the result of giving Adobe hundreds of thousands of dollars...

Funny how many haulage companies with British names and addresses are using foreign-registered vehicles, isn't it...
