I think what you were seeing was more due to ATM overhead than the DSLAM trying to be cute with throttling. Because ADSL encapsulates everything in ATM even small IP / Ethernet frames get broken up into lots of ATM cells which can add upwards of 20% overhead. So an ADSL line trained at 8Mb/s will never provide 8Mb/s of usable throughput to the end user. Some ISPs actually advertise targeted throughput instead of train rate and set the train rate a certain percentage above the target throughput to compensate. Others just advertise train rates and have disclaimers in the fine print.

I've had my hands inside most Gen 1, 1.5 and 2nd Gen DSLAMs and never seen any with automatic throttling like you described.

(Gen 1 being units that just function at the ATM layer requiring an external system to bridge to Ethernet or IP. Gen 1.5's being upgraded Gen 1s with crude bridging, and Gen 2 being units that were designed to terminate connections directly from the ground up.)

“Hacktivism”. Never heard the word before today and now it’s on every second post.

I really hope it doesn’t catch on. I cringe every time I hear it.

Without Hacktivism we'd never get to experience the joy of Hacktivo. Thats right, now you'll never miss another poorly coordinated DDoS because you're too busy actually accomplishing things. Just set the Hacktivo to record your favorite troublemakers and play back the lulz when YOU'RE ready to watch, on your schedule.

Submission + - Operation Payback's Command and Control System

Predius writes: "Fun with Anonymous — Infiltrate the hive

Anonymous has been in the news again lately for loosely coordinated DDoS attacks on high visibility targets in the name of defending Wikileaks. Their weapon of choice is a modified LOIC (http://en.wikipedia.org/wiki/LOIC) install, a 'network stress tool' written to include IRC driven command and control. Volunteer LOIC installs become part of the 'Hive Mind' which Anonymous directs to attack chosen targets.

The command and control of LOIC is actually VERY simplistic. Figuring it out takes very little effort thanks to the modified LOIC install including nearly the full source of all code used to make the prepackaged binaries.

By default LOIC expects the user to direct it. Upon providing an IRC server, port and channel it switches to Hive Mind mode and connects to IRC automatically and joins the specified channel to await instructions. Instructions must be posted by a channel owner or operator, or in the topic of the channel. As security, all LOICs use predefined username patterns as well as specific user and real name info.

Nick: LOIC_XXXXXX (Replace the X's with upper or lower case letters, must be 6 total to match the channel invite mask.)
Username: IRCLOIC
Realname: Newfag's remote LOIC
Server: thealps.anonops-irc.com or irc.anonops-irc.com port 6667
Channel: #loic
CTCP Version Reply: SmartIrc4net 0.4.0.28389

From the LOIC README:
-------------------------------------------
==============================
|| CONTROLING LOIC FROM IRC ||
==============================

As an OP, Admin or Owner set a channel topic or type message with (as an example
):
!lazor targetip=127.0.0.1 message=test_test port=80 method=tcp wait=false random
=true

To start attack type
!lazor start

Or just append "start" in the END of the topic
!lazor targetip=127.0.0.1 message=test_test port=80 method=tcp wait=false random
=true start

To reset options back to default:
!lazor default

To stop attack:
!lazor stop

And remove "start" from topic (if exists)
You can also replace "start" by "stop" in the END of the topic.
-------------------------------------------

There are bots in the channel that periodically do version checks on all bots in the channel, so make sure you get the version string right. Also there are real users who monitor for odd activity, so I suggest just idling with your LOIC simulation and setting up a second connection to poke around with using normal looking credentials. So far they have been fairly quick to g-line suspected fake LOICs that botch any of the credentials and post repeated warnings to attack any found 'with anger'.

#OperationPayback is where the live chaos is, mostly a shouting match of various self proclaimed 'hacktivists' with a few trying to direct the horde with various degrees of sucess. This channel is also handy to monitor as changes to the attack plan will be announced along with start times.

As various external sources disable Anonymous assets, either irc servers directly via DoS attacks or by disabling the domains used new replacements are announced here as well. The Hive appears to be very slow in recovering from these hits given that the simplistic control structure doesn't include a means to auto-update the hive settings, relying on constant user monitoring and intervention instead. There is active discussion in #newloic on an upgraded or replacement tool in progress."

Depends on the state. Maine for example is an at will employment state. An employer can just decide "You're done" and you no longer have a job. There is no requirement for just cause. If you can prove it was due to something inappropriate you can bring a case, but the burden of proof is on the employee at that point.

It's a two stroke boxer motor with a second set of outboard pistons running opposite to the primary units.

The only real big changes worth noting over existing auto engines - it's a two stroke, and they have it running off a turbo decently.

If you were to make a modern DFI two stroke with their turbo you would see the same compactness and emissions and even FEWER moving parts. The double opposed setup is just flash to distract you from the fact that it's a two stroke.

Now, combine said theoretical DFI motor with Polimotor's research, aka a nearly all plastic motor and you'll see the power density go through the roof. THATs the engine I want.
