Well, to port tcpdump, you'd _also_ have to port the the Berkeley Packet
Filter, as that's (one of) the ways tcpdump does it's packet sniffing.


% ls -l /usr/sbin/tcpdump
240 -r-xr-xr-x  1 bin  bin  114688 Mar 27 23:51 /usr/sbin/tcpdump

"It's in there!".  tcpdump has been a part of NetBSD for a while, at least
since 1.0.  You'll need to compile bpf into your kernel to use it, but
once that's done, it works great.  I use it all the time.

I assume you mean "not knowing", right?

There are some packages on, but I think that's been kinda
stale lately.  A couple of quick hints:

- Delete any prototypes for malloc() or sys_errlist[]
- Include unistd.h in any file that uses lseek()
