Running on a Kali VM in Virtual Box.
when trying to run -l or --localnet I get the following issue

sudo arp-scan --localnet
Interface: eth0, type: EN10MB, MAC: XX:XX:XX:XX:XX:XX, IPv4: 192.168.0.111
WARNING: Cannot open MAC/Vendor file ieee-oui.txt: Permission denied
WARNING: Cannot open MAC/Vendor file mac-vendor.txt: Permission denied

the only devices I am picking up at the VM and the host.
I can ping and have internet on the VM

I am not sure if it is a VM issue or arp scan - I am a noob so I probably just haven't done something correctly
Any help is greatly appreciated

This can happen if you run arp-scan as root when it has been built with Linux capability support. To check this, run arp-scan --version - if it was built with capability support the output will include Built with libcap POSIX.1e capability support.

If arp-scan is built with capability support, it doesn't need to run as root provided the package maintainer installed the binary with the cap_net_raw capability. If it's built with capabilities support you shouldn't need to run as root as the package maintainer should set the required capability. If you can't run arp-scan without sudo then you can set the required capability on the binary with this (assuming it's in /usr/bin/arp-scan - adjust as required):

sudo setcap cap_net_raw+p /usr/bin/arp-scan
