Can't use nmap on 10.1

[Andrea Venturoli]

Hello.

I've always used NMap, but now I've got several 10.1 boxes where it 
doesn't work.

> # nmap -sP -PI 192.168.1.0/24
>
> Starting Nmap 6.47 ( http://nmap.org ) at 2015-07-13 11:50 CEST
> route_dst_generic: Failed to obtain system routes: getsysroutes_dnet: sysroutes_dnet_find_interfaces() failed


I tried searching for this, but most results are in Russian and I cannot 
read them. I only found one in English and it says it's PF's fault, but 
I don't have PF enabled.

I tried playing with -e option (e.g. "nmap -sP -PI 192.168.1.0/24 -e 
rl0"), but what I get is:

> I cannot figure out what source address to use for device rl0, does it even exist?

Of course rl0 exists.



Any hint?

  bye & Thanks
