For example, on SUSE that's what we call "LPF" - the Linux version of the BPF device. For example, the ping utility uses ICMP (Internet Control Message Protocol, IP protocol number 1) and you can write your own ICMP based code with. Stream sockets, however, are what we are using in this tutorial, since we are dealing with TCP protocols, so we will specify SOCK_STREAM as the second parameter to socket(). To allow an unprivileged process to access a raw socket you will need to write a proxy daemon that runs privileged and is allowed in selinux to create a raw socket. A call socket. TCP Sockets. This is usually only needed for sockets opened in “raw” mode (SOCK_RAW); for the normal socket modes, the correct protocol is chosen automatically if the protocol is omitted or zero.
