Ciao a tutti,
uso Ubuntu 5.10 e ho fatto un "chkrootkit" e un "rkhunter
--checkall"........bhe ho notato due cose strane.
1) Quando ho fatto il "chkrootkit" mi da tra le tante cose questo risultato:
Checking `bindshell'... INFECTED (PORTS: 4369)
2) Quando ho fatto il "rkhunter --checkall" mi a dato:
Vulnerable applications: 1
bha....io non ho delle conoscenze tali da capire dov'è il
problema.....cmq vi allego i log delle due operazioni.
