Hmmmm ... The better can be simply to use a second interface. What is the utility to modify and reinject a packet on the same link than the good one : the receiver will always received the good packet first ignoring your modified one. No ??? Except if you've a real need for this.

Envoyé : mercredi 7 janvier 2004 15:27 À : [EMAIL PROTECTED] Objet : [tcpdump-workers] capturing and injection on same interface hi everyone, i have a c-proggie using libpcap for captureing packets, and injecting them with altered payload only back to interface...now you can imagine i would be recapturing packets i just processed (altered+injectedback)...so i get into a loop! Is there a way to prevent that? knowing i am on OpenBSD 3.4. Is it using Hashtables? maybe having some values of IP header checked, and compared ti values saved in hashtables of packets injected? any1 faced such a problem?
