libnet_get_hwaddr(): socket: Permission denied

[lasyka]

When i run arping -i wlan0 192.x.x.x , get this error :
libnet_get_hwaddr(): socket: Permission denied.

I,m already use the root account to run it.
and i wrote simple test code to invoke libnet_get_hwaddr() ,there's no problem,and retun right hwcode. Or run other app that uses libnet‘s method,also no problem.
only run arping ,get this error.

My env. is linux chroot on android phone:
Linux kali 3.10.40-lasyka+ #30 SMP PREEMPT Sat Sep 29 19:40:50 CST 2018 armv7l GNU/Linux

Could you add both:

1. The output of arping run with -vvvvv
2. The smaller test program, in full?

Thanks for your help. use the vvvvv option got the drop uid/gid info. And add -g option to run arping,the error is gone.

So you're saying Android doesn't have a group for "nobody"? What user did you choose with -g?
