      nmap just sits there after requesting a scan, saying it is starting but no results.
      if i try from the command line, it can't find the appropriate interface.
      if i specify the interface ng0 with nmap -e ng0, it cannot find the route.

      nmap –iflist should produce the interfaces
      the most logical one is nmap -e ng0
      i would try nmap -e xl0 (my wan interface) but nmap --iflist does not detect it.

      thanks.

      nmap --iflist
