tcpflow:tldr:40fdd

The command "tcpflow -c -i ${eth0} port ${80}" is used to capture and analyze network traffic on a specific network interface and port using the tcpflow tool.

Here's a breakdown of the command components:

• "tcpflow": It is the command-line utility that allows the capturing and analysis of TCP/IP network traffic.
• "-c": This flag instructs tcpflow to capture and analyze the captured traffic as it happens in real-time.
• "-i ${eth0}": It specifies the network interface to capture traffic from. In this case, it is set as ${eth0}, which is likely a placeholder for the actual network interface name. The eth0 interface is commonly used for the first Ethernet interface on Linux systems.
• "port ${80}": This specifies the port number to filter the captured traffic. In this case, it is set as ${80}, which is likely another placeholder for a specific port number. Port 80 is commonly used for HTTP traffic, so it's likely capturing HTTP-related network traffic.

Overall, this command captures and analyzes TCP/IP network traffic on a specific network interface (${eth0}) and filters out traffic related to a specific port (${80}, likely HTTP traffic).
