Frans Gidlöf <neko@skebo.ac>: > So how do you catch one of those tcp-ack-no-payload packets with > IPFW?. AFAIK ipfw doesn't (yet?) have that iplen thing, but ipfw2 has it, or will have it. you might experiment with `tcpoptions ...' and `established', though. i don't want to do that, but am still interested if these less powerful measures make a difference, so keep us posted, please. clemens
