There's no way for bpf to show you packets that never come down the wire to your machine. I've never operated a switch myself. Maybe there's a way to tell it that a certain port should get all of the packets, whether they're destined for that machine or not. -- Matthew Hunt <mph@astro.caltech.edu> * Stay close to the Vorlon. http://www.pobox.com/~mph/ * To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
