[Linux-bruxelles] installation de ntop sur redhat 9

[Frédéric de Thysebaert]

Bonjour
je suis débutant sur linux et essaye d'installer ntop sur une redhat 9, nouvelle installation du système en tant que server
j'ai cjhargé le dernier rpm  ntop-2.2-0.i386.rpm
lorsque je lance rpm -i ntop-2.2-0.i386.rpm j'ai comme résultat

error: Failed dependencies:
        libpcap is needed by ntop-2.2-0
        libcrypto.so.2 is needed by ntop-2.2-0
        libpcap.so.0.6.2 is needed by ntop-2.2-0
        libssl.so.2 is needed by ntop-2.2-0
        librrd.so.0 is needed by ntop-2.2-0

si je tente d'installer libcap avec rpm -i libcap-1.10-15.i386.rpm 
warning: libcap-1.10-15.i386.rpm: V3 DSA signature: NOKEY, key ID db42a60e
        package libcap-1.10-15 is already installed

ou est mon erreur ?

merci
