I understand. Booted from knoppix 5.0.1, executed a |
| 35 |
|
| 36 |
'chroot /mnt/hda1 chkrootkit' and a |
| 37 |
'chroot /mnt/hda1 rkhunter -c' |
| 38 |
|
| 39 |
- both scans brought back nothing. From what I have read the chkrootkit & |
| 40 |
rkhunter binarys would have been from the CD and therefore untainted ? Am I |
| 41 |
correct ? |
| 42 |
|
| 43 |
Are there any other checks I can do - re-installing the system is not my |
| 44 |
preferred option :) |
