iproute2 per principianti

[crystal13]

Salve,
devo iniziare a fare un traffic control tramite iproute2 su una macchina linux che mi è stata assegnata nella mia facoltà.
Dato che non mi è stato dato nessun input, sto cercando informazioni in merito ad iproute2.

La prima domanda che faccio è:
come faccio a capire se sta già installato? (distro: Fedora)

EDIT1:
se digito: /etc/iproute2
mi dice che è una directory.
Da questo capisco che dovrebbe essere già installato, no?

Si fa cosi` x vedere se e` installata una cosa su Fedora:

[le@PackardBell ~]$ rpm -qa|fgrep -i iproute
iproute-2.6.22-2.fc8

('rpm -qa' restituisce la lista di tutti i pacchetti installati, 'fgrep -i' fa una ricerca per la stringa che metti dopo)

Comunque si /etc/iproute2 fa parte del pacchetto, come puoi anche verificare con rpm -qf /etc/iproute2, ma quello che interessa a te e` principalmente il comando /sbin/tc, ed eventualmente /sbin/iptables (se dovessi fare anche filtering, classificazione avanzata del traffico o pasticci vari sui pacchetti.)

Per il resto questi sono alcuni link utili sul traffic control:
