How are you physically configured? Is the network traffic in question running *through* your snort box (ie: the machine running snort acts as a router with 2 network cards), or alongside it? Hogwash will only work if your snort box is an in-line router, and will not work as a single-interface side-monitor connected via a hub or ethernet tap.
Hogwash will only work if configured like this: internet ---- snort_hogwash_machine --- protected machine it will not work like this: internet ------ hub/tap ------ "protected" machine (not really protected) | snort_hogwash_machine.The second setup works for normal snorting, but does not work for hogwashing since the snort machine can only see the packets in question, it can't block them since it's not "in line". If the second case is your only possible configuration, your best bet is flexresp, but that works by spoofing reset packets and does not work 100% reliably.
