Install nbench:
| 1. Install rootsh if you havent |
2. Open terminal and write:
|
3. Download by writing:
(If you don't have wget: apt-get install wget) |
| 4. write: root |
5. Make a directory:
|
6. Move the files to a better location:
(a tip is to use tab-key to finish easy.. like /h[tab] to make /home/) |
7. To get permission:
|
8. Run and wait for it to finnish:
or
