Install nbench:
1. Install rootsh if you havent
2. Open terminal and write:
cd /home/user/MyDocs/Downloads/
3. Download by writing:
wget http://my.arava.co.il/~matan/770/n900/nbench wget http://my.arava.co.il/~matan/770/n900/COM.DAT wget http://my.arava.co.il/~matan/770/n900/NNET.DAT
(If you don't have wget: apt-get install wget)
4. write:
root
5. Make a directory:
mkdir /home/opt/nbench
6. Move the files to a better location:
mv /home/user/MyDocs/Downloads/nbench /home/opt/nbench mv /home/user/MyDocs/Downloads/COM.DAT /home/opt/nbench mv /home/user/MyDocs/Downloads/NNET.DAT /home/opt/nbench
(a tip is to use tab-key to finish easy.. like /h[tab] to make /home/)
7. To get permission:
chmod 777 /home/opt/nbench/nbench
8. Run and wait for it to finnish:
/home/opt/nbench/./nbench
or cd /home/opt/nbench/ ./nbench
