Jose, If I read his query correctly, he wants to classify IPX or something else. /etc/protocols is a mapping of identifiers for the contents of IP packets, so in this case, /etc/protocols doesn't help him. Seems like he needs a "protocol generic" (or better yet for him, "protocol ipx"), which would allow him to count byte offsets in the manner of u32. I know of no such tool. -Martin : > My question is can classify the non-IP traffic?

"iptables" can also match non-IP : protocols, using "--protocolo PROTOCOL". You can't go deeper into these : non-IP packets, but you can mark them by protocol, using any of the : protocols in the "/etc/protocols" file. : : Hope it helps. : : -- Martin A.
