Why would you sniff from your "home" computer? If you are the sysadmin, then you sniff from the server and from home you could ssh to your server to check logs of course. On a more technical note, you have to be on the same subnet of either the point of origin or the destination machine. In other words at one of the two choke points. That is short of having some tool installed on the other person's home computer which again crosses that line. You obviously can't be at the home user's choke point because what lawful authority would you have to be sniffing on that subnet owned by his ISP? Jacques B.
