If that's the case, then the interface should be updated to avoid confusion. You can expect questions from random visitors every few days until it is.

would the system be bak online if some1 volunteered a few TBs of Hdd space? just a question though does the host with all the tables perform calculations when performing a lookup or do the clients do the calcs then send back for a lookup?
I really would like to know what's required to bring this system back up, who knows if Pb can't do it there mite be someone out there ;)

If you can volunteer, then PM PB. I think he would like the idea.

not only would that require a lot of disk space, but also lots of cpu power and most importantly a shitload of traffic.

clients do the calcs, server does the lookup (afaik)

A lot of traffic, disk space and CPU...
A distributed approach to that maybe?

that already is a distributed method!
more distributed = more traffic.

I think lookups can be done server side only, thus eliminating the need for bandwidth. Perhaps setting up nodes doing calculations for a part of the tables (one doing NTLM/LM, and one MD5 for example, depending on total table sizes) would be enough for now. Adding some 2 TB disks containing the tables to a normal machine running rcracki, plus a method to provide hashes (web application, rpc, whatever) and returning them to the FRT web server would suffice to setup a cracking node.

It will be very hard to have this work without being distributed. When a new table is created there is a huge rush of hashes to look up in that table. Currently there is a NTLM table with a chain length of 40,000 being generated and 11,904 uncracked NTLM hashes. The current speed of 542 clients is 1.17 billion links per second. This means it will take over 2.26 hours to generate the end points to look up in the table and I think it's roughly 50% of that to check for false alarms. So about 3.39 hours plus time to search the tables. It's even worse for MD5 tables since there's over 6 times as many uncracked hashes. Now if you have one computer generating the end points to look up and checking for false alarms it's going to take like 20 days plus time to search the tables. The bandwidth for the distributed method will be 3.23 mbps down for 2.26 hours (3.06 GiB) and upload 2.04 GiB.

(40,000 * 39,999 / 2) links/hash * 11,904 hashes / 1,170,000,000 links/second / 3,600 seconds/hour = 2.26 hours
39,999 end points * 11,904 hashes * 6 bytes/end point * 8 bits/byte / 1,000,000 bits/mbits / 2.26 hours / 3,600 seconds/hour * 1.15 = 3.23 mbps
39,999 end points * 11,904 hashes * 6 bytes/end point * 1.15 / 1,024 ^ 3 GiB/byte = 3.06 GiB
(39,999 / 2) start points * 11,904 hashes * 8 bytes/start point * 1.15 / 1,024 ^ 3 GiB/byte = 2.04 GiB
8 bytes per start point is actually 6 bytes for the start point and 2 bytes for the chain position.
