There is no need to configure the 'hellanzb.conf' file if you are using the LottaNzb GUI.
First grab lottanzb deb file from:
Once you have that file and it is saved to a location of your choice like 'Desktop' or whatever
Then open the terminal VIA: Applications> Accessories>Terminal
From there copy and paste command:
*Enter your password when prompted*
sudo apt-get install hellanzb
NOTE: Your password will not show up, it will be Blank.
Once Hellanzb is installed then double click the 'lottanzb_0.3.1_all.deb' file and follow the prompts to install the GUI
From there it is only a matter of setting up your addy, username, and amount of connections.
Select 'Standalone Usage mode' and enter your server info and passes.
After all of that you can start the program from 'Applications>Internet>Lottanzb'
To change the amount of connections or if you want it to unrar and par check automatically all you have to do is go to 'Edit>preferences'
The 'Servers tab' will allow you to change the amount of connections up to 25 per server , with or without SSL.
The 'general Tab' allows you to change download folders and set it to "download par files only when necessary to repair" , limit speed (useful if you share a connection and do not want to bog down the whole network.), minimize to system tray, and a few other things. But all in all if you want a nice, easy to use client this is it. But I have had a bit to much of the sauce and a few to many VK ES, so either way enjoy
