Pyrit shutdowns my computer #369

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
I'm trying to use pyrit to crack my wpa network and when i launch the command 
"pyrit batch" for the batchprocess, after 1 minute my pc goes off.
I have imported a lot of passwords (about 300mb) and i want to know if could i 
avoid this problem.. maybe using less memory!

I've also tryed to config .pyrit/config but it didn't help me.

That's my benchmark:
Pyrit 0.4.1-dev (C) 2008-2011 Lukas Lueg http://pyrit.googlecode.com
This code is distributed under the GNU General Public License v3+

Running benchmark (1345.9 PMKs/s)... - 

Computed 1345.89 PMKs/s total.
#1: 'CUDA-Device #1 'GeForce 315M'': 988.2 PMKs/s (RTT 3.0)
#2: 'CPU-Core (SSE2)': 191.1 PMKs/s (RTT 4.0)
#3: 'CPU-Core (SSE2)': 188.6 PMKs/s (RTT 3.8)
#4: 'CPU-Core (SSE2)': 197.8 PMKs/s (RTT 3.9)

I use arch linux

Either your overheating or your power supply cannot handle the load, most 
likely. Get lmsensors and check your temps while running pyrit.

Yes your problem is probably overheating, when the cpu get past a preset 
threshold, the motherboard simply shutdown the computer to protect itself. 
haykay maybe right too about tinking that the power supply may not handle the 
load, as you use the 3 core+a cuda card.
Solution #1:Shutdown your computer, open it and take a look a the cpu heatsink, 
if he is full of dust, then your problem is simply that the airflow is too 
restricted. Remove it and clean it. This is the cause #1 of overheating.
Solution #2: Does your computer is inside a desk or something like? If yes, you 
may need to get it out so the fan will not blow hot air trying to cool itself.
Solution #3: If you overclocked your cpu, the 2 problem may rise. Downclock it 
or buy bigger heatsink. The psu may not handle the load, buy a bigger one.
Solution #4: Buy yourself a bigger power supply. If you have a "general usage" 
power supply that is only 300-350Watt, this is surely your problem. With a 
triple core and a cuda card, a 450-500Watt will be able to handle even the more 
intensive load. I have a 500Watt for my dual core, 2 cuda card, 4 hdd, and he 
handle it. (That depend on which card you have, count 75Watt/6Pin 
connector+75Watt for the main connector, this will give you the total wattage 
you need only for the card.)

Finally, if you have done all the 4 solution and the computer continue to 
shutdown alone, take a look at the capacitors on the motherboard(they look like 
small batteries), if the top is not flat(and have a convex shape), or you 
notice a brown tick liquid that goes out of the top, then the electrolytic 
capacitors of your motherboard are gone! If you have done some electronic work, 
and you know what you do, then find new capacitors that have exactly the same 
rating (same voltage(Normally 6.3Volt), and same capacitance(Normally between 
1000uF and 3300uF). After that completely strip your computer to have the 
motherboard, unsolder the old caps, and solder ther new one. This will resolve 
the problem. If you're not sure about your soldering skills, bring it to a 
electronic repair shop, and tell them to change the caps that are broken only.

So i hope you will find your problem!!

Oh... Sorry i didn't saw this: "#1: 'CUDA-Device #1 'GeForce """315M"""'': 
988.2 PMKs/s (RTT 3.0)"
If you try to do this on a laptop, then i'm pretty sure that he overheat. 
Almost all the laptop i've seen in my hole life are not adequately cooled. And 
they are a PITA to clean. You can try to buy a laptop cooler, a fan that will 
blow air on the bottom of the laptop, this will cool it a little bit more, but 
i'm not sure that this will do the job... I can't help you... Sorry!

Ok, thanks a lot!

also taking your cpu/gpu cooler off and removing that crappy poor conducting 
garbage that the manufacturer uses between the cpu and heatsink, and replace 
with some decent performance thermal compound, arctic silver etc. I usually get 
a 5C-10C temperature reduction by doing this alone. I recommend everyone do it.
