[ubuntu-it] PACKET SNIFFER

[Pit3r°°]

Ciao a tutti,
mi connetto ad Internet con un router adsl 'prestige 600 series' che fa 
uso del DHCP, la distro è 'Ubuntu 5.10 (breezy)'. Facendo una scansione 
con chkrootkit trovo un PACKET SNIFFER:

"eth0: PACKET SNIFFER(/sbin/dhclient3[6423])"

googglando in rete vedo che potrebbe essere un falso positivo, ma avrei 
voluto avere un riscontro con rkhunter:

http://www.rootkit.nl/projects/rootkit_hunter.html

ho scaricato l'ultima versione (1.2.8) e come descritto in questo sito 
ho tentato l'installazione:

che però ha fallito:

-Potete darmi qualche consiglio?
-A parte rkhunter cè qualche altra alternativa a chkrootkit?
-Come mai l'installazione di rkhunter è fallita?


Grazie.
