Getting started with linux network configuration (I) Network Interface www.2cto.com ① naming rules linux kernel specifies different prefixes for interface names based on the interface type, each interface is allocated a number from scratch. For example, all Ethernet interfaces start with eth, eth0, eth1, and eth2 indicate the first, second, and third Ethernet cards, respectively. ② the NIC configuration information is displayed. Only the active Nic ifconfig displays all interfaces (NICS) ifconfi
