Hello, netter! (I am a new user, please forgive me if the question is novice) Is there a way to read all the packets transmitting in the Ethernet? More specifically is there a way to read all the IP packets or Ethernet packet no matter what is the packet's destination address? The platform will be unix running TCP/IP. I am doing network security so this is quite important. Any suggestions? Also I'll appreciate if you could tell me some books/articles on unix security/bugs. Please e-mail reply directly to me. Many thanks in advance! Regards, Weijun Wang (E-mail: wangw@ul.ie) Dept. of Electronics Univ. of Limerick Ireland

Any suggestions? This question borders on the outrageous. I will assume that your intention really is security and not espionage. In that case, forget about packet snooping and get a smart router or gateway that does packet filtering. You have every right to restrict access to and from your domain in any way that you wish, but keep your nose out of those packets -- it has no business being there. >Weijun Wang (E-mail: wangw@ul.ie) >Dept. of Electronics, Univ. of Limerick, Ireland Bruce -- Bruce R.
