In computing, netstat is a command-line network utility that displays open network sockets, routing tables, and a number of network interface (network interface controller or software-defined network interface) and network protocol statistics. It is available on Unix, Plan 9, Inferno, and Unix-like operating systems including macOS, Linux ...
iproute2 utilities communicate with the Linux kernel using the netlink protocol. Some of the iproute2 utilities are often recommended over now-obsolete net-tools utilities that provide the same functionality. [4] [5] Below is a table of obsolete utilities and their iproute2 replacements.
In combination with netstat -aA and grep, fstat will identify the process associated with a network connection, just as will ofiles. In 1991, Vic Abell publishes lsof version 1.0 to comp.sources.unix. He notes: [1] Lsof (for LiSt Open Files) lists files opened by processes on selected Unix systems.
Many Linux distributions have deprecated the use of ifconfig and route in favor of the software suite iproute2, such as ArchLinux [3] or RHEL since version 7, [4] which has been available since 1999 for Linux 2.2. [5] iproute2 includes support for all common functions of ifconfig(8), route(8), arp(8) and netstat(1). It also includes multicast ...
nslookup, used to query a DNS server for DNS data (deprecated on Unix systems in favour of host and dig; still the preferred tool on Microsoft Windows systems). vnStat, useful command to monitor network traffic from the console. vnstat allows to keep the traffic information in a log system to be analyzed by third party tools.
In UNIX computing, the system load is a measure of the amount of computational work that a computer system performs. The load average represents the average system load over a period of time. It conventionally appears in the form of three numbers which represent the system load during the last one-, five-, and fifteen-minute periods.

BusyBox is a software suite that provides several Unix utilities in a single executable file. It runs in a variety of POSIX environments such as Linux, Android, [8] and FreeBSD, [9] although many of the tools it provides are designed to work with interfaces provided by the Linux kernel. It was specifically created for embedded operating systems ...
