RE: Hashtopus - distributed solution - oktar - 06-29-2015

Hello,

curlyboi, got a question for you.

I have two hashing rigs, running on Ubuntu 14.04 LTS. Rig #1 has 4x Gigabyte R9 280x GPUs, Rig #2 has 4x MSI Twinfrozr III 7950 GPUs.

I use latest version of oclHashcat + Hashtopus.

Hashtopus works great as it should, but I have a problem with "Measuring keyspace..." part when adding new tasks.

Normally, when I start oclHashcat directly without Hashtopus it happens only one time, during first use of that specific dictionary. I assume the result of dictionary stats generation is written on disc and used for next tasks to avoid repeating.

For large dictionaries it takes substantial amount of time to complete, even 30 minutes.

I noticed that every Hashtopus client tries to generate dictionary stats by itself, however when I connect only 1 agent and it finishes "Measuring keyspace" the second agent assigned to task doesn't do that again and starts hashing at sight without generating dictionary stats.

The problem is that when I add another task with the same dictionary, Hashtopus clients generate directory stats again which is a time waste.

Imagine that I have dictionary that is processed within 2 hours, but between each task I have to wait 30 minutes before the hashing starts for dictionary generation of the same file, which is a time and resources waste.

Is there a way to avoid repeated keyspace measurements by Hashtopus?


RE: Hashtopus - distributed solution - curlyboi - 06-30-2015

Good point. I will try to fix this but there is a risk. What if i add a state "keyspace measuring", and an agent performing this will crash? Then the task will frozen in that state. Sure, i could add some timeout but how much time is too much here? we are talking hours


RE: Hashtopus - distributed solution - skillskills - 06-30-2015

I seem to have an issue with Hybrid Attacks when prepending the mask.

My job as follows works fine:
-a 6 -m 1000 #HL# example.txt ?a?a

However the following causes the clients to hand at measure keyspace:
-a 6 -m 1000 #HL# ?a?a example.txt

As per the documentation of oclhashcat should the input not be valid?

I think the benefits are much greater than potential risk. All I would have to do is paying attention during first use of this specific dictionary, checking if everything went OK.

My gain is avoiding repeating such task hundreds of time for the same dictionary across hundreds of future tasks.

I think you could even skip timeout part, just wait until it finishes and maybe you could just add the choice of using such feature in config file so everybody can choose whether they like repeated keyspace masurements or not.

It would be very helpful curlyboi, at least for me.

You have to use -a 7 for the second example.


RE: Hashtopus - distributed solution - skillskills - 07-03-2015

You have to use -a 7 for the second example.

Thanks!

If I want to update hashtopus can I simply copy the new release on top of the old one? Or does the DB need to be updated as well?

It depends. Sometimes there are changes in the DB, sometimes they are not. You can find this out in github.

Do you get to the point where oclHashcat is executed or does it crash before that?

No, exact `hashtopus debug`output is on scneenshot.
Tried to run this task on other computer, it also "Stopped working" in same manner and dump was created (I can't attach it to message and will email to you if you wish)
