[split] Another Ethereum Password Crack

[daveinli1218]

i need to revise my original question.
i am trying to crack a 12 character password, the 1st 6 known characters, rest are random.
I have tried Mask and Charsets but when it gets to end of 9 characters hashing it gives me an error, custom charset 1 is undefined. not sure where I am going wrong

I tried a mask of ******?l?u?d?1?1?1?1?1?1 (stars are known)
and a charset like this, which increments but fails after 9
******?l?u?d?1
******?l?u?d?1?1
******?l?u?d?1?1?1
******?l?u?d?1?1?1?1
******?l?u?d?1?1?1?1?1
******?l?u?d?1?1?1?1?1?1
******?l?u?d?1?1?1?1?1?1?1
******?l?u?d?1?1?1?1?1?1?1?1
******?l?u?d?1?1?1?1?1?1?1?1?1
******?l?u?d?1?1?1?1?1?1?1?1?1?1
******?l?u?d?1?1?1?1?1?1?1?1?1?1?1
******?l?u?d?1?1?1?1?1?1?1?1?1?1?1?1
