Hash Cracking Assignment - Given part of a password

[Frkn]

Sory it is my first question here on this forum and I hope I can find an answer. I have a question about my Hash-Cracking Assignment. I have already a part of the cracked password. I am giving an example here. Let's say the characters "pass" is already given and the last two "rd" is given. I need to find the characters in between (Pass??rd). These two characters can be anything. I tried it with hashcat and used the Brute-Force Attackmode. But unfortunalety I am getting no results. 

I thank you already in advance.


The command I used is something like: 

Code:

hashcat -a 3 -m 100 hashfile.txt ?u?l?l?l?a?a?l?l

I also tried:

Code:

hashcat -a 3 -m 100 hashfile.txt Pass?a?a?l?l

I always getting the "Exhausted" Notification. 

BTW: If there is a related post to this can you send me the link for itm I could not find it.

You can try Pass?b?brd. Or, perhaps, these two characters are multi-byte. Then you can try Pass?b?b?brd, Pass?b?b?b?brd etc.
