I recently updated to nmap 4.01 and have since then the following problem:

Starting Nmap 4.01 ( )
getinterfaces: Failed to open ethernet interface (fxp0). A possible 
cause on BSD operating systems is running out of BPF devices (see
********************************************************** I raised the number of bpf's from 8 to 16 and recompiled the 
kernel. However, I don't know what to do exactly with MAKEDEV. The 
bpf-section of MAKEDEV looks like this:

         mkdev bpf       c 23 0
         lndev bpf bpf0

Should I modify this, or is that irrelevant?

That's a i386 NetBSD 3.0 RC1.

Thank you very much,
