ping requires CAP_NET_RAW capability to be executed 1) if the program is used for non-echo queries (See -N option), or 2) if kernel does not support non-raw ICMP sockets, or 3) if the user is not allowed to create an ICMP echo socket. The program may be used as set-uid root.

Programs that use icmp protocol, such as ping, use a type of socket called SOCK_RAW. The nature of using raw IP sockets is that ALL packets received that match the protocol type of the raw socket are delivered to ALL the sockets using that protocol. It is up to the application to read all the data in it's socket buffer

    Raw Sockets − These provide users access to the underlying communication protocols, which support socket abstractions. These sockets are normally datagram oriented, though their exact characteristics are dependent on the interface provided by the protocol.

    Sep 24, 2018 · For example, on SUSE that's what we call "LPF" - the Linux version of the BPF device. You should see LPF/interface/MAC lines logged when dhcpd starts, these are the raw sockets initializing. When operating in this mode, dhcpd opens the raw sockets, and a backup BSD/UDP socket (called the "fallback interface"), which you will be seeing in netstat.

    If you're working in C, you can send a raw Ethernet frame using socket(AF_PACKET, SOCK_RAW, ...), and passing it a pointer to a raw buffer that you've generated yourself (e.g. by following the frame layout at wikipedia). It's been a long time since I've done this, so I'm not going to attempt to write a representative code snippet...

    Feb 11, 2015 · I don't quite see why in his case he cant use a program with capabilities to bind the raw socket and then pass that on to other programs, but perhaps that gets too complicated. The ping example is also odd, as we have specific ping sockets to solve this problem, but as far as I can see they have not reached mainstream distros. No idea why not.
