je veux ajouter une adresse IP (multicast 228.0.0.4) dans la plage de 224.0.0.0 - 239.255.255.255 dans la table des routes du noyau, donc j’ai utilisé
Sudo route -nv add -net 228.0.0.4 -interface eth0
mais ça me donne:
root@macavity:/home/gaiz# route -nv add -net 228.0.0.4 -interface eth0
route: invalid option -- 'i'
route: invalid option -- 't'
route: invalid option -- 'r'
route: invalid option -- 'f'
route: invalid option -- 'a'
route: invalid option -- 'c'
Usage: route [-nNvee] [-FC] [<AF>] List kernel routing tables
route [-v] [-FC] {add|del|flush} ... Modify routing table for AF.
route {-h|--help} [<AF>] Detailed usage syntax for specified AF.
route {-V|--version} Display version/author and exit.
-v, --verbose be verbose
-n, --numeric don't resolve names
-e, --extend display other/more information
-F, --fib display Forwarding Information Base (default)
-C, --cache display routing cache instead of FIB
<AF>=Use '-A <af>' or '--<af>'; default: inet
List of possible address families (which support routing):
inet (DARPA Internet) inet6 (IPv6) ax25 (AMPR AX.25)
netrom (AMPR NET/ROM) ipx (Novell IPX) ddp (Appletalk DDP)
x25 (CCITT X.25)

Je crains de ne pas comprendre très bien la multidiffusion, mais le problème de votre commande est l’interface. Cela devrait plutôt ressembler à ceci:
Sudo route -nv add -net 228.0.0.4 dev eth0
Dans les pages man route
, un exemple:
route add -net 224.0.0.0 netmask 240.0.0.0 dev eth0
This is an obscure one documented so people know how to do it.
This sets all of the class D (multicast) IP routes to go via
"eth0". This is the correct normal configuration line with a
multicasting kernel.
