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? Cheers - This is the TCPDUMP workers list. It is archived at http://www.tcpdump.org/lists/workers/index.html To unsubscribe use mailto:tcpdump-workers-request () tcpdump org?body=unsubscribe
