Distributed Rainbow Table Generator

Ein paar Antworten vom Admin:

The goal of FreeRainbowTables.com is to prove the insecurity of using simple hash routines to protect valuable passwords, and force developers to use more secure methods.
By distributing the generation of rainbow chains, we can generate HUGE rainbow tables that are able to crack longer passwords than ever seen before.
Furthermore, we are also improving the rainbow table technology, making them even smaller and faster than rainbow tables found elsewhere, and the best thing is, those tables are freely available to download from our site!

Is it legal or moving into the greyzone?
It is perfectly legal.
You can view this project like a gun. It can be used to defend yourself(by testing your own security), but it can also be used to attack others.
Abuse of the tables are out of my control. But to abuse these tables, you first need to retrieve the hashes from a server. If you got those, your already inside the system and probably have root/admin access.
Whats the status of the boinc server?
Its beta status. I'm still working on fixing the last pieces. (problems with the small txt files downloaded, problems with libgc on Linux clients)
What applications are planned?
Other than the rainbow table generator, I'm also planning to make the index calculator and false alarm checker for distributed password cracking
However, i still need to think about how to do it. I only want people to freely participate in the hash cracking.
Maybe i will just remove the online hash cracking service.
Is there a fixed credit system or how its calculated?
Its a fixed credit based on the chainlength of the current set.
Is the project useful for anything?
The resulting rainbow tables are used by many security professionals to test the strength of passwords.
How much traffic caused by dl/ul?
The resulting file per WU is 9mb. Each WU will take ~ 2.5 hours to calculate / core.
There is nothing to download (except the binary)

Das stimmt einfach nicht:
Es gab zwar mal ein BOINC projekt das rainboiwtables erstellt hat (hashbreaker) aber wir haben BOINC vorher noch nicht genutzt.

sollte jemand interesse an den bisher erstellen tables haben soll kann ich nur unseren http mirror empfehlen (www [dot] tbhost [dot] eu). der dll läuft eig über FTP und ist nicht gedrosselt. Sollte jemand planen mit mehr als 7mb/s zu saugen bitte vorher bescheid geben, da es ein shared host ist und der schon mal in die knie gegangen ist ;)

Für weitere Fragen stehe ich hier und in unserem board (auch the_drag0n) gerne zur verfügung.

Naja, geklaut ^^ Ich meinte nur das es schon wieder fast das gleiche ist, viele User haben aber bestimmt wieder wenig Interesse von der Art dieser Projekte.

Falls ihr mehr Interesse habt, das Projekt publik zu machen, solltet ihr unter http://boincstats.com/ mit Freigabe der projekt-url/stats/ im Forum posten ;)

Credits wurden nun fairerweise von 15 auf 50 angepaßt, enspricht fast einem Quad im 1:1 Verhältnis oder knapp 22cr/h.

Der Admin hat gewechselt oder ist noch kein neuer da, zumindest ist ein backup vom Projekt gemacht wurden, wird aber ein neue Person gesucht, die das übernimmt und hostet.

Shutdown of freerainbowtables.com- 2009-07-16 01:56:40

Freerainbowtables.com is now officially inactive.
Over the last months i had no time to support it anymore and so i decided to shut it down. The website + forums will remain active, but no tables will be generated anymore. The tables generated so far are still available for download at both the GARR mirror and tbhost.eu
If you can't (or won't) download the tables from the mirrors, i can still offer to ship all the available tables on an 1.5TB external harddrive for 550US$

If YOU wan't to continue this project, contact me at admin@freerainbowtables.com and i will send you the sources needed to overtake it.
Und wieder eins weg.

DistrRTgen by freerainbowtables.com has had some problems lately, but thanks to ZiaSpace ( http://www.ziaspace.com/hosting/ ), we now have a brand new server to run our site on!

We are emailing you to tell you that DistrRTgen is back online and your more than welcome to start helping us again to generate more rainbow tables

To help us do so, simply go to http://www.freerainbowtables.com/en/download/ and follow the link to download the latest BOINC client.
After installation, point the client to use the project URL http://boinc.freerainbowtables.com/distrrtgen/

We hope to see you soon!

Sincerely,
The team of FreeRainbowTables.com
Und schon wieder da :coffee:

New Windows CUDA 3.2 app release

#11 Post by odicin » 11.08.2011, 21:35

http://boinc.freerainbowtables.com/dist ... p?id=38#55
We have released a CUDA 3.2 version of Windows distrrtgen. DistrRTgen will no longer suck 100% of a single processor anymore, so you can use it for other calculations!
Das sind doch mal gute Neuigkeiten.

Gruß Odi

Nachtrag: Und wie es aussieht auch ein geändertes Creditsystem. Es gibt nun fixed 2000 Credits für eine WU.

Die CPU-Auslastung liegt bei mir bei 0.5 und damit unter der von PG PPSsieve.

Dir GPU-Last liegt bei mir gerade mal bei 13%, CPU ist zwar höher mit 0.64 aber nicht messbar, gibt wohl kein Schalter wo man die Last erhöhen kann.

Update:

Blöderweise nach update des Grafiktreibers auf 280.26 gab es eine neue alte 3.37 app. Anfangs läuft die Karte jetzt mit 50% , zwischendurch mal mit 97%.

Der Validator mag wohl die Ergebnisse nicht, da die trotzdem richtig beendet wurden sind. Kannst du bloß dort im Forum posten, hatte gerade für die den CUDA Client für Win getestet.

Es gab heute nochmal ne aktuelle 3.40 für Windows, dort wurden aber wohl nur einige Performance-Bugs behoben. Bugs unter Linux sind mir nicht bekannt.

Mit Linux kenne ich mich nicht wirklich aus, das einzige was ich dazu mal gelesen habe war, das die Cuda-Treiber zum Linux-Kernel passen müssen. Auf die schnelle habe ich noch das dazu gefunden: http://www.dotsch.de/boinc/DotschUX-CUDA.html. Welcher Cuda-Treiber ist denn bei Dir installiert?

v3.44 hat jetzt endlich volle GPU Last ohne lags. Bin aber leider wieder auf 260.99 Treiber zurück wegen der Runtertaktung.

Die Version behebt auch endlich mein Problem mit der 8800GT. Diese hatte bisher immer doppelt so lange wie eine GT430 benötigt, obwohl eigentlich hätte schneller sein müssen.

Our first validator snafu was more minor in scope and something that did not seem to justify the time commitment to work on correcting the credits.

However, the issues over the last 24-48 hours have been so severe in scope and impact that there was nothing fair about just say tough. Also, based on data that continues to remain favorable it seems that somewhere between: heat, load, or power supply lays the culprit. We continue to run in as trimmed down a fashion as possible to allow WU hand out, validation, and credit. This will continue until our host gets some high cfm fans in place or we need to stop work hand out due to disk space.

I spent this evening writing code to grant credit to results that failed validation but match the result marked as valid for the workunit. The updates have been applied for the result, host, user, and team total_credit. I did not try to adjust all the expavg values *just* total_credit. Also, please note that applies to WUs that already have a valid result turned in *and* up to and including the past 10 days.

There are many results waiting for a result to mark the workunit valid and will allow me to run this code again. Please note this code is very specific to the two issues encountered between the validator failures and the upload handler failures that resulted in validation failures. Also, please note this level of credit adjustment marks the most extreme needed and applied in the history of the project under BOINC in over 3 years.

We certainly cannot promise that every single cobblestone has been granted or will be but I think everyone should be fairly accepting of their credits versus a few days ago. Please use the forums to discuss this and other issues as much as possible. Our admin staff of 2 people, who both have full time day jobs, is not able to investigate every single user. Hopefully though this adjustment and ones to come as soon as a valid result+workunit are available to DC against will overall be fair in compensating everyone.
Wenigstens quel kümmert sich um das Problem mit den ungültigen Ergebnissen.

@diclo: Vermutlich könnte das dein Problem mit dem Validator gewesen sein.
Validation errors?
To those of you whom are running the 7.x development client, you will get validation errors. To fix this problem, please downgrade your BOINC client to 6.12.34 which is the recommended version
