Compare disk utilization in combination with interrupts from our IDE controller, or compare the network bandwidth numbers directly with the disk throughput . IP command is kind of a replacement of ifconfig command. This command is used to perform different network administration tasks. This command is used to display or manipulate routing, devices, network devices, and tunnels. Although it is similar to ifconfig command but way too powerful including more functions and facilities in it.

Traceroute – print the route packets trace to network host. Ping is a utility normally used for testing connectivity between two systems on a network (Local Area Network or Wide Area Network ). To deactivate or shut down a network interface, type. To assign an IP address to an interface, use the following command. Here is an example to display the status of all active network interfaces. It is also used to view the IP Address, Hardware / MAC address, as well as MTU size of the currently active interfaces. Ifconfig is thus useful for debugging or performing system tuning.
