<p>Ngrep (network grep) is a simple yet powerful network packet analyzer. It is a grep-like tool applied to the network layer – it matches traffic passing over a network interface. It allows you to specify an extended regular or hexadecimal expression to match against data payloads (the actual information or message in transmitted data, but not auto-generated metadata) of packets.</p>
<p>This tool works with various types of protocols, including IPv4/6, TCP, UDP, ICMPv4/6, IGMP as well as Raw on a number of interfaces. It operates in the same fashion as <a href="https://www.tecmint.com/12-tcpdump-commands-a-network-sniffer-tool/">tcpdump packet sniffing tool</a>.</p>
<p>The package ngrep is available to install from the default system repositories in mainstream Linux distributions using package management tool as shown.</p>
<pre>
$ sudo apt install ngrep
