SABnzbd Forums

I currently have ubuntu 12.04 install with sabnzbd.

I am noob i would like to know how to reset my username and password.

Thank You in advance.

Assuming you're talking about SABnzbd's username/password.
Do you still know them? If so, go to Config->General and remove both.
If not, stop SABnzbd and edit ~/.sabnzbd/sabnzbd.ini to find them.
~/.sabnzbd is a hidden folder in your home folder.

Thank you very much.
