This will give the whole 'capture-comand# the rights of root, which |
| 29 |
I want to prevent (see my posting). Instead I want to give it only |
| 30 |
higher priorities for I/O-usage and CPU-usage. It should still act |
| 31 |
with user rights for all other puposes. |
| 32 |
But thank you for your help anyway. |

Best regards. |
