Full Version: Wordlist generator Cluster
You're currently viewing a stripped down version of our content. View the full version with proper formatting.
Hello everyone,

I have a spare Gpu rig where I have correctly configured Hashcat / Ubuntu 18.04 Server and it is working fine.

This rig have a really cheap processor, therefore there is not enough power to produce enough work to load all the Gpus at 100%.

Few month ago I have build a Raspberry Pi B3 + Cluster and my idea is to use it to generate the wordlist and pipe it straight to the rig, doing so hopefully I will be able to remove the processor bottleneck and let the Gpus run much faster.
Actually I am trying to write different programs in c to build up some wordlist, but being honest try to use all the resources of the cluster is not easy at all , and maybe someone already did it better than how I could.

At this point I would like to understand if there is any feature of Hashcat or any program around that is going to be suitable for my intent.

Have anyone used a Cluster before for do something like that? 
Maybe someone can give me some advise...

My rig

12 x Amd ( rx 470,480,570,580 4/8 Gb)
Intel G 4400 3.30 Ghz
16 Gb DDR4
Evga G3 1000w
2 x Hp 1200w Server

Thanks a lot to everyone and have a lovely day Smile
you're assuming your ethernet network connection is faster than your cpu/cpu-bus?

To be honest I don't even have thinker about that, And it is a really good point , and a mistake on my side.

The point is that if I try to generate the wordlist with the processor and pipe it in to  hashcat it cannot load the gpus at 100%, but if I use an already made wordlist from the ssd the Gpus are running at 100 % constantly ( in another rig that I have with 6 gpus and a i7 4770 k).

For this reason The idea was build the wordlist with the Cluster and then use the processor just for pipe them to the Gpus.

I just saw the Cluster in the corner of my room and I want to try to use it ,  I didn't find any documentation about it, only people that were computing the hashes in the Cluster.

So I can imagine that the only solution is a double socket motherboard.

Otherwise ,is possible to use one of the Gpus to generate the wordlist for the other gpu?

What do you mean by Cluster? What hardware is the cluster made of? :)
