boinc user password?

[sunk818]

I was trying to edit global_prefs.xml so I could change the number of CPUs used and what percentage to run them. I could open it with vi, but could not get root access nor boinc user access to change the file. What's the boinc user password?

Did you try sudo?

same problem here... searching for the standard password for 'boincuser' as well.
I've written the BOINCOS-Graphical-XFCE-Beta-v2.0.1.img file from here to a USB-Stick
and booted it up, but now i'm stuck at the login screen, because I don't know the standard password.
I've tried sudo but it didn't work...
UPDATE 1:

Logging In:
The OS will boot into a text-based console and prompt for a login. Type the username
“boincuser”, press enter and then type the password which is a single spacebar.

Ok spacebar doesn't work either...
UPDATE 2:
I've found the hashed user/password in the shadow file...

boincuser:$6$UAhtfP.8nLFbHMEy$LG7sRlxwZnkJTggScwMIxj7z4hRL0vEziT8oagBC9OYlQQivj/q/HTyezPcnOyqrtWPniGtL73gh3JIroz.eO/:17466:0:99999:7:::

but i've never cracked one before...
UPDATE 3:
Every single one of the standard '/usr/share/wordlists/' from kali failed.
Regarding brute-force I've tried (?a) [1], (?a?a) [2], (?a?a?a) [3], (?d?d?d?d) [4] and (?l?l?l?l) [4] so far without success.
I've been 50% through (?l?l?l?l?l) [5] but that would have take over 2h and I think I haven't turned on GPU mode yet...
UPDATE 4:
Ok whatever... I just booted from another linux,
deleted the password-hash for the boincuser in the /etc/shadow file and logged in that way.
Not the best way, and I really wanted to know what the password was, but hey it works...
