libpcap & BSD packet filtering

Does the QNX4 or RTP TCP/IP stacks support/implement the BSD Packet
Filter stuff.

I am trying to port nmap so I can perform native port scans of my
systems to verify that they are “secure” from casual attack.

nmap in turn requires libpcap which depends on the BSD packet
filtering. My understanding is that the RTP tcpip stack is a BSD
stack so how do I go about “turning on” the BPF in the stack.
(Under linux and standard *nix’s this would be a kernel recompile…)

TIA,
Bill

Thanks,

There is also a thread in qdn.public.porting titled:
“BPF porting - help needed” from 11/3/00
which indicated that libpcap et al has already been ported by Xiaoden
Tang but as the thread you mentioned indicates, the devn* code needs
to be put in promiscuous mode for it to work correctly… So I guess
I’ll just sit on my hands and wait…
