View source for Setting the capabilities to sniff on an interface with libpcap

So i did this in rust, however is the case for any language. This allows you to run a program as a non root user but have access to the interface for sniffing.

This command sets the capabilities of the executable. It must have both cap_net_admin and cap_net_raw.

<pre>
sudo setcap cap_net_raw,cap_net_admin=+ep target/debug/rp2009_sniffer
</pre>

The code then also needs to set it?

<pre>
       caps::raise(None, caps::CapSet::Inheritable, caps::Capability::CAP_NET_ADMIN).unwrap();
       caps::raise(None, caps::CapSet::Ambient, caps::Capability::CAP_NET_ADMIN).unwrap();
       caps::raise(None, caps::CapSet::Inheritable, caps::Capability::CAP_NET_RAW).unwrap();
       caps::raise(None, caps::CapSet::Ambient, caps::Capability::CAP_NET_RAW).unwrap();

</pre>
