He specifically said in his original post that putting a machine between the router and his lan wasn't an option. His question was, "Is there a program where I can see whats going on from the computer on that network?" The answer to that question is, if he's on a switched network, no. Not without a topology change. If he can't put a box between the switch and router how likely is it that he's going to be able to put a hub between the switch and router and then attach a box to that? -- Thanks, Josh Paetzel _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[EMAIL PROTECTED]"
