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.
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
sudo retains the user's invocation rights through a grace period (typically 5 minutes) per pseudo terminal, allowing the user to execute several successive commands as the requested user without having to provide a password again. [21] As a security and auditing feature, sudo may be configured to log each command run.
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.
ifconfig — Display or configure network interface. inotifyd — Run a program when a filesystem event occurs. insmod — Load the module named MODULE passing options if given. install — Copy files and set attributes. ionice — Change the I/O scheduling priority of a process. iorenice — Display or change I/O priority of existing process.
Convolutional codes are processed on a bit-by-bit basis. They are particularly suitable for implementation in hardware, and the Viterbi decoder allows optimal decoding. Block codes are processed on a block-by-block basis. Early examples of block codes are repetition codes, Hamming codes and multidimensional parity-check codes.
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]
The Copy/Paste Detector (CPD) is an add-on to PMD that uses the Rabin–Karp string search algorithm to find duplicated code. Unlike PMD, CPD works with a broader range of languages including Java, JavaServer Pages (JSP), C , C++ , Fortran , PHP , and C# code.
