Network listening technology in a Linux system-Linux Enterprise Application-Linux server application information. See the following for details. In the network, when information is transmitted, you can use tools to set the network interface in the listening mode to intercept or capture the information being transmitted in the network, to launch attacks. Network listening can be implemented in any location mode of the network. Hackers generally use network listening to intercept user passwords. For example, when someone occupies a host, then he wants to extend the result to the whole LAN of the host. Listening is usually a shortcut they choose. Many times I have seen some beginners on various security forums. They think it is very easy to enter the Intranet if they occupy a host. In fact, it is not easy to enter a host and then transfer it to another machine in its internal network. Because in addition to getting their passwords, you also have the absolute path they share. Of course, the path must end with the write permission. At this time, running the listeners on the controlled host will have a great effect. However, it is a difficult task, and it also requires the patience and adaptability of the attacker. It mainly includes:
