how to run hashcat in a distributed environment - jason_gap - 03-30-2017
Recently, I want to run hashcat on 10 devices ,each device has one gpu card. I need to seperate the keyspace into 10 parts for load balancing. for example, the whole keyspace is '?a?a?a?a?a?a?a', how should I set the parameter to run hashcat? in the future , how to run hashcat in a distributed environment for load balancing?

1.
Code:
hashcat --keyspace -a 3 ?a?a?a?a?a?a?a
814506252.
Code:
81450625 / 10 = 81450633.
Code:
hashcat -m 0 -a 3 -w 4 --skip 0 --limit 8145063 hash_file.txt ?a?a?a?a?a?a?a
hashcat -m 0 -a 3 -w 4 --skip 8145063 --limit 8145063 hash_file.txt ?a?a?a?a?a?a?a
hashcat -m 0 -a 3 -w 4 --skip 16290126 --limit 8145063 hash_file.txt ?a?a?a?a?a?a?a
hashcat -m 0 -a 3 -w 4 --skip 24435189 --limit 8145063 hash_file.txt ?a?a?a?a?a?a?a
hashcat -m 0 -a 3 -w 4 --skip 32580252 --limit 8145063 hash_file.txt ?a?a?a?a?a?a?a
hashcat -m 0 -a 3 -w 4 --skip 40725315 --limit 8145063 hash_file.txt ?a?a?a?a?a?a?a
hashcat -m 0 -a 3 -w 4 --skip 48870378 --limit 8145063 hash_file.txt ?a?a?a?a?a?a?a
hashcat -m 0 -a 3 -w 4 --skip 57015441 --limit 8145063 hash_file.txt ?a?a?a?a?a?a?a
hashcat -m 0 -a 3 -w 4 --skip 65160504 --limit 8145063 hash_file.txt ?a?a?a?a?a?a?a
hashcat -m 0 -a 3 -w 4 --skip 73305567 hash_file.txt ?a?a?a?a?a?a?aIt's very easy, it couldn't be easier than that.
Furthermore, there are a lot of 3th party tools (like hashtopussy etc) - wrappers - that show you how to do it. This question is also among the most answered and therefore easy to find the answer if you use the forum search.

thank you for your answer .
I tried as follows :
./hashcat64.bin --keyspace -a 3 ?a?a?a?a
857375 (95^3)
./hashcat64.bin --keyspace -a 3 ?a?a?a?a?a
81450625 (95^4)
./hashcat64.bin --keyspace -a 3 ?a?a?a?a?a?a
81450625
./hashcat64.bin --keyspace -a 3 ?a?a?a?a?a?a?a
81450625
./hashcat64.bin --keyspace -a 3 ?a?a?a?a?a?a?a?a
7737809375 (95^5)
./hashcat64.bin --keyspace -a 3 ?a?a?a?a?a?a?a?a?a
735091890625 (95^6)
./hashcat64.bin --keyspace -a 3 ?a?a?a?a?a?a?a?a?a?a
5287606593041 ( ??)
I wonder how to calculate keyspace in hashcat?
