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
The ethtool userspace API can be accessed from programs written in the C and C++ programming languages through the C standard library or C++ standard library respectively. Several scripting languages such as Perl and Python provide ethtool API bindings that allow programmers using these languages to write scripts that can control NIC's.
tcpdump is a data-network packet analyzer computer program that runs under a command line interface. It allows the user to display TCP/IP and other packets being transmitted or received over a network to which the computer is attached. [3] Distributed under the BSD license, [4] tcpdump is free software.
sudo (/ s uː d uː / [4]) is a program for Unix-like computer operating systems that enables users to run programs with the security privileges of another user, by default the superuser. [5] It originally stood for "superuser do", [ 6 ] as that was all it did, and this remains its most common usage; [ 7 ] however, the official Sudo project ...
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 network controller implements the electronic circuitry required to communicate using a specific physical layer and data link layer standard such as Ethernet or Wi-Fi. [a] This provides a base for a full network protocol stack, allowing communication among computers on the same local area network (LAN) and large-scale network communications through routable protocols, such as Internet ...
One convenient means to provide a PPS signal to a computer system is to connect that signal to a modem-control pin on a serial-line interface to the computer. The Data Carrier Detect (DCD) pin is frequently used for this purpose. Typically, the time-code output of the time source is transmitted to the computer over the same serial line.
In Linux distributions based on 2.2.x Linux kernels, the ifconfig and route commands are operated together to connect a computer to a network, and to define routes between computer networks. Distributions based on later kernels have deprecated ifconfig and route, replacing them with iproute2. Route for Linux was originally written by Fred N ...
