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' il 
problema.....cmq vi allego i log delle due operazioni.
