I've never bought one myself). tcpdump on a cheap NetBSD/FreeBSD/BSDI box (even an old 486 will do just fine) will easily keep up with all of your ethernet traffic, and its free, not $26,000. Its also VERY flexible -- I've never needed anything else. Best to do this on a box that does native BPF, though (asn an example SunOS does not do BPF and NIT can't handle the traffic without dropping most stuff). Perry
