Comment Re:Firewalls (Score 2) 158

You open a SSH connection (client->server:22). This port is allowed on the firewall, it lets you through. But then the server decides to listen on UDP:(random port) and tells the client, back through the (encrypted) initial connection, which UDP port to contact. So you initiate a SSP UDP session on that port. How does the firewall knows it should let you through? Since the port number is communicated on an encrypted session, it doesn't have access to that information. So how does this work in a secure environment? The paper doesn't mention any mean for the server to communicate with the network which port its listening on.

My guess is as good as anyone else's, but I surmise it does a bit of packet trickery. Once device A (behind firewall) is connected to device B (may/may not be behind firewall, but at least one port is open, 22 by default in this case), device A can create an SSH tunnel...they really are rather neat and VERY useful as a means of security. For example, I have webmin running on a server, but its port (10 000) is blocked by the firewall. Once I connect to SSH I can redirect packets to a certain IP:Port combo (device A's IP:Random Port#) to the servers local address (127.0.0.1) and new UDP port, and voila: hidden/secure/direct connection. One can even make a tunnel in the other direction, so that the server can connect to a remote device in the same manner, and any application won't realize that it's even connecting to anything outside of its network.

Whomever thought of and implemented SSH tunnels is a master genius. I would shake his/her hand if I ever saw them.

Yellow pages, 411.com, or perhaps the local legal aid. You can just call one and set an appointment. Trust me, they like to take new clients, it equals more money for them. "Having a lawyer" means you've been to one, and have agreed that you can call them on any particular matter (some lawyers know civil law, some know only criminal law, some family law...you get the point). If you are charged with a criminal offence, just ask for 'duty council'...it's the lawyer that's on the clock at that time...you can ask for advice and it's free.

It's not always the best advice though...pay for it yourself if you want decent advice.

Disclaimer: I am not a lawyer. But even if I was, I'd have a lawyer.

Comment She received an Email? (Score 4, Insightful) 227

FTFA:

"She said she received an e-mail in January from a Toronto Police officer in 14 Division "asking me to contact them about an incident that occurred at The Piston (on Bloor St. W., Nov. 19, 2011)."

And then she did? WTF! That's the last thing anyone should do.

So...you received an Internet message from someone claiming to be a cop? Step #1: Ignore it. There's no way on god's green earth that anyone should respond to a frickin' electronic message from a cop. Clearly the cops didn't think it was important enough to send a car around to her place. If she ignored it, it probably would have went no where. The only possible first step is contact a lawyer. She believed she'd be cleared because that she is innocent? What?! Is she new? Since when has that ever happened? Cops are interested in closing the file...if your name is in it, or someone else's, it doesn't matter.

DO NOT TALK TO POLICE, especially on purpose. Talk to your lawyer, have your lawyer talk to police.

Seconded. Like you, there is 0% chance of me being mind and dollar fucked into oblivion. I own every toy and electronic I ever wanted. I go where I want, when I want. I work as much as I like (which is a lot), and I don't get guilt tripped. One day I will find a woman that is compatible with the above, and she will be goddamn amazing. Then I'll share everything I have with her. Until then, I carry on.

And ppl do not understand why I WANT us to continue drilling all over USA. I figure that once Americans start to get earthquakes, polluted waters esp. in our aquifiers, and see the repercussions of this 'clean' source of jobs, then MAYBE, JUST MAYBE, we will finally figure out that we need to change our policy. And I can not think of anything that would be better then to get the west off imported energy (other than to add that we quit importing bad goods and food from china).

I can. It's the reason that every country with half a brain and a little foresight would want to import all oil:

1. Import all oil, pay increasing prices (it's worth it)
2. Use/maintain local refinement infrastructure
3. Drain world of said oil (this is actually going to take a long time, long after everyone currently alive is dead)
4. Tap local wells, sell oil to foreign entities at insane prices
5. Hope alternative fuels haven't become viable
In essence: use everyone else's before using your own.

What the US public needs to do is revolve before #3 happens (nationalize resources) so that -they- can recoup the money they've spent on all the other oil.

Yep, and I surmise it's because they don't want to stop giving you credit (everything would stop, then)...and when someone goes bankrupt, it's hard to justify giving them credit. If bankruptee repays something, they'll likely have some modicum of a credit score, and they can still get credit. Last I heard around here, they called it "a proposal"...but it's the same thing.

Russia, Europe Seek Divorce From U.S. Tech Vendors 201

dcblogs writes "The Russians are building a 10-petaflop supercomputer as part of a goal to build an exascale system by 2018-20, in the same timeframe as the US. The Russians, as well as Europe and China, want to reduce reliance on U.S. tech vendors and believe that exascale system development will lead to breakthroughs that could seed new tech industries. 'Exascale computing is a challenge, and indeed an opportunity for Europe to become a global HPC leader,' said Leonardo Flores Anover, who is the European Commission's project officer for the European Exascale Software Initiative. 'The goal is to foster the development of a European industrial capability,' he said. Think what Europe accomplished with Airbus. For Russia: 'You can expect to see Russia holding its own in the exascale race with little or no dependence on foreign manufacturers,' said Mike Bernhardt, who writes The Exascale Report. For now, Russia is relying on Intel and Nvidia."

Submission + - Bell Canada to end throttle (huffingtonpost.ca)

inject_hotmail.com writes: I just caught wind of a story over at the Huff. Bell Canada has written a letter to the CRTC indicating that it will end traffic shaping on March 1, 2012. Although Bell says that this is due to "increasing popularity of streamed video and other traffic" and "P2P file-sharing, as a proportion of total traffic, has been diminishing", it's far more likely that they are interested in higher revenue. In all likelihood, the change of heart is based on the fact that Bell has moved most of their customer base to, and offer no alternative to, low-usage-cap UBB packages, which would ultimately generate more income or deter full usage of their service (and thus require less infrastructure investment).
