I'm no TCP protocol expert, but doesn't a NAT router change the time stamp when it NAT's the packet? And if it currently doesn't, I'm sure it's just a simple firmware change to add that feature and make the ISP's efforts worthless.

So there's nothing to worry about here.]]> http://www.dslreports.com/forum/remark,12855987 Tue, 08 Mar 2005 03:34:46 EDT Re: Anonymously Track a PC Anywhere on Net http://www.dslreports.com/forum/remark,12832835 MoeDumb : It's crackers to slip a rozzer the dropsy in snide.

It would be impossible for a single deployed solution to parse traffic from a constantly evolving number of arrangements behind customers' public interfaces- especially if LAN side hacks appeared that were designed to overwhelm and not just obscure.]]> http://www.dslreports.com/forum/remark,12831409 Fri, 04 Mar 2005 15:41:50 EDT Re: Anonymously Track a PC Anywhere on Net http://www.dslreports.com/forum/remark,12830936 Fraoch :

From how I read is it possible to just turn off timestamps in the tcp/ip? Then no more detection

...and we show how one might use a Fourier transform on packet arrival times to infer a device’s clock skew.
...

They almost had me believing it. Packet arrival times have random influences that no "Fourier transform" could account for. This is bullshit -- the paper is a fraud -- but I"ll keep reading it just to make sure. Besides, I'm pretty sure that TCP does not waste 32 bits on a time stamp unless there is a real-time/ordering requirement (but that could have changed in the last 5 years since I dealt with it). ICMP request are mentioned -- but don't most router firewalls block those anyway?

I'm not talking massive overclocks, I'm talking very slight clock alterations.

I'm not even sure it's possible. Just an idea.]]> http://www.dslreports.com/forum/remark,12830580 Fri, 04 Mar 2005 14:10:46 EDT Anonymously Track a PC Anywhere on Net http://www.dslreports.com/forum/remark,12830538 Fraoch : Oh, very nice. I'm sure ISPs would love to know how many devices are connected to their line so they could increase charges accordingly.

It could have some good security benefits but it sure opens the doorway to abuse.]]> http://www.dslreports.com/forum/remark,12830538 Fri, 04 Mar 2005 14:03:59 EDT
