bcrypt hash with salt

[sleclerc]

Thank you for your response, 

If I would like to brute force attack this hashed password what command structure would I used?
-I know nothing about the length or characters used. upper/lower case, special character, numbers

if I use the following command hashcat -m 3200  -a 3 -1 ?a hashes.txt ?1?1?1?1?1?1?1?1?1?1

-m 3200 bcrypt encryption
-a 3 brute force
-1 pattern ?a = upper/lower, special characters and numbers
hashes.txt is my file with the hashes

I get the following message
integer overflow detected in keyspace of mask: ?1?1?1?1?1?1?1?1?1?1?1?1

how do I brute force the password if I don't know the length or characters used, but I do have the salt used.
