Linux Command
Function
ifconfig also: ifcfg, ifup, ifdown, ethtool, nm-tool
/etc/init.d/networking restart ip link set down ip link set up
The ifconfig command is a tool used to display and configure network interfaces. This command will display information about the network card, IP address, broadcast address, and network mask. It also shows how many packets were received and transmitted. There is also information about the loopback device (lo).
ping
The ping command allows the user to test whether or not a network connection is active, the speed of that connection, and how a network behaves given specific data loads.
arpalso: arping
The arp command by itself is used to view the information currently in the ARP table (Address Resolution Protocol). This table maps the IP address of machines on your network segment with their MAC address.

When operating in "promiscuous" mode, NIC passes every frame received from the network to the kernel. Each NIC has a MAC address. Each NIC has a hardcoded IP address. NIC checks the destination address for every packet, if the address matches the cards MAC address, it is further copied into a buffer in the kernel. Every NIC on the network will hear all the frames on the wire.arrow_forward
