Pls check wether the command tcpdump shows card in promiscious mode. If it does show itself,then check if you are hooked on to switched = network.Switch allows only the packet destined for your box to reach you = along with broadcast packets. I am reasonnably convinced that it is = 'The' problem with your box. Let me know if it is the same problem. Bye ---------- From: Leonard C. Sent: Friday, March 19, 1999 4:53 PM To: questions@FreeBSD.ORG Subject: BPF not working? I'm trying to get trafshow and tcpdump working on my system, but I'm finding that all the traffic that I can view is data going to and from = my box along with stuff to the broadcast address. Any ideas why this is happening? I've compiled BPF support into the kernel and the devices = are there, and both trafshow and tcpdump both run fine, so I'm a bit puzzled = as to why the thing isn't working. The funny thing is that I see a lot of packets showing up as input errors, which I think might have something = to do with it. The machine runs NATd with ipfw in open mode, and has two ethernet = cards. ed1 is the external network, and ed0 is the internal.
