USBKill is anti-forensic software distributed via GitHub, written in Python for the BSD, Linux, and OS X operating systems. It is designed to serve as a kill switch if the computer on which it is installed should fall under the control of individuals or entities against the desires of the owner. [1]
Similarly, the kill(1) command allows a user to send signals to processes. The raise(3) library function sends the specified signal to the current process. Exceptions such as division by zero , segmentation violation ( SIGSEGV ), and floating point exception ( SIGFPE ) will cause a core dump and terminate the program.
killall is a command line utility available on Unix-like systems. There are two very different implementations. The implementation supplied with genuine UNIX System V (including Solaris) and Linux sysvinit tools kills all processes that the user is able to kill, potentially shutting down the system if run by root.
The other pseudo-device, the slave, emulates a hardware serial port device, [1] and is used by terminal-oriented programs such as shells (e.g. bash) as a processes to read/write data back from/to master endpoint. [1] PTYs are similar to bidirectional pipes. [3]: 1388 Devpts is a Linux kernel virtual file system containing pseudoterminal devices.
Components of some Linux desktop environments that are daemons include D-Bus, NetworkManager (here called unetwork), PulseAudio (usound), and Avahi.. In multitasking computer operating systems, a daemon (/ ˈ d iː m ən / or / ˈ d eɪ m ən /) [1] is a computer program that runs as a background process, rather than being under the direct control of an interactive user.
Computers on network with very fast connection usually require more brute force in order to successfully perform a DOS attack on them. Otherwise the command can be run without the -1 to -9 option or the -i option. [2] This is a description of one of the various dsniff programs. This text belongs to the dsniff “README” written by the author ...
The kill command is a wrapper around the kill() system call, which sends signals to processes or process groups on the system, referenced by their numeric process IDs (PIDs) or process group IDs (PGIDs). kill is always provided as a standalone utility as defined by the POSIX standard.
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.
