Bug in SHA512 (Unix) Hashcat?

[MuMMeL]

Hello everyone

My Problem ist the Attack of this Hash Value (Ubuntu 12.04)

oh-lala:$6$zv8dHfXf$HFYc5i.i9NcutOUKniZpkhIx9XkW8qo61XdXJZxpZXjtkV9MmPi9owX9ib1VNt5E1M88MCt4UovX7bHNlYQUw/

The Password Structure is unknown and the User "oh-lala" died last Week.

My loooong Dictionary Attack was useless.

PasswordsPro said the Password is "4rfvbgt5" but it is wrong.

I install a Ubuntu 12.04 in a virtual Maschine and setup a Test User

tester:$6$n.x8pyjJ$y/9YEn.7e3TrjfAmbvVK89rE9u5YlUBJyqWambc6wH4oAbk.ooVn4W8yEQijadbVgKLG9omTmVJBzX.CtMLTa1

The Password is "12345"

i tried a short Dictionary with "12345" inside and Hashcat cant find it?
A Bruteforce Attack was also unsuccessful.

The Hashcat Settings:

hashcat-cli32.exe --hash-mode 1800 --attack-mode 3 c:\Path\testershadow.txt ?d?d?d?d?d

Is everything wrong or I've misunderstood something?
Use Ubuntu a different kind of Hash?

I love Hashcat

Sorry for my really bad English

Best regards

MuMMeL
