As this comes up now and then, let me summarize how this is wrt. Red Hat
Linux:
RHL60 and previous: promisc on, man page ok (tcpdump-3.4 without kuznet)
RHL61: promisc off, man page wrong (tcpdump-3.4 with kuznet)
RHL62: promisc off, man page ok
RHL7[01]: promisc off, man page ok
Next release: promisc on, man page ok (tcpdump-3.6.2 and some patches)
