ifconfig is also commonly used to change the medium access control (MAC) address of an interface. In this process, the network interface is first disabled (set down) with the ifconfig command, followed by a MAC change command: ifconfig wlan0 down ifconfig wlan0 hw ether 13:11:20:33:49:66 ifconfig wlan0 up
ethtool is the primary means in Linux kernel-based operating systems (primarily Linux and Android) for displaying and modifying the parameters of network interface controllers (NICs) and their associated device driver software from application programs running in userspace.
tcpdump prints the contents of network packets. It can read packets from a network interface card or from a previously created saved packet file. tcpdump can write packets to standard output or a file. It is also possible to use tcpdump for the specific purpose of intercepting and displaying the communications of another user or computer.
As a security and auditing feature, sudo may be configured to log each command run. When a user attempts to invoke sudo without being listed in the configuration file, an exception indication is presented to the user indicating that the attempt has been recorded.

Wireless tools for Linux is a collection of user-space utilities written for Linux kernel-based operating systems to support and facilitate the configuration of device drivers of wireless network interface controllers and some related aspects of networking using the Linux Wireless Extension.
The construction of a failure detector is an essential, but a very difficult problem that occurred in the development of the fault-tolerant component in a distributed computer system. As a result, the failure detector was invented because of the need for detecting errors in the massive information transaction in distributed computing systems.
An Ethernet frame including the EtherType field. Each lower slot designates an octet; the EtherType is two octets long. In modern implementations of Ethernet, the field within the Ethernet frame used to describe the EtherType can also be used to represent the size of the payload of the Ethernet Frame.
