tcpdump:tldr:b9a9f
The command "tcpdump net ${192-168-1-0-24}" is used to capture network traffic using the tcpdump utility.
Here is a breakdown of the command components:
-
"tcpdump" is a command-line tool used for network packet analysis. It captures packets flowing through a network interface and provides detailed information about those packets.
-
"net" is a tcpdump option used to specify a network or network range for capturing packets. In this case, it tells tcpdump to capture packets that are either coming from or going to the specified network.
-
"${192-168-1-0-24}" represents the network range or subnet that needs to be captured. In IP address format, it is written as 192.168.1.0/24. The "/24" denotes the subnet mask, which indicates that the first 24 bits of the IP address are fixed and the last 8 bits can vary.
So, the command captures and displays network traffic for the subnet 192.168.1.0/24. It can be used to monitor network activity, analyze network issues, or troubleshoot network problems.
