o All devices on an Ethernet network have a Media Access Control (MAC) address, sometimes called a hardware address. This address is independent of a host’s IP address, and it is unique to the host’s Ethernet network (but not necessarily a larger software network such as the Internet)....
It provides logdaemon style login access control based on login names, host or domain names, internet addresses or network numbers, or on terminal line names in case of non-networked logins. By default rules for access management are taken from config file /etc/security /access.conf if you d...

NOTE Not all devices have device files because the block and character device I/O interfaces are not appropriate in all cases. For example, network interfaces don’t have device files. It is theoretically possible to interact with a network interface using a single character device, but because...
