Keywords: IP raw sockets X-Newsreader: TIN [version 1.2 PL2] Woops! Sorry about the last post, I was on the wrong host! The message was supposed to be: Is it possible to grab IP packets coming in from a certain interface before the kernel routes them? (through a raw socket perhaps) Or does this have to be done inside the kernel? I can grab ICMP packets no problem via a SOCK_RAW using IPPROTO_ICMP. The socket just hangs on IPPROTO_RAW though. Any info would be appreciated. -------------------------------------------------------------------- Peter Howlett Atlantic Systems Group E-Mail: phowlett@mailhub.ASG.unb.ca Fredericton, N.B. Canada
