Other network configuration management systems are mainly targeted for smaller embedded systems, such as OpenWRT’s netifd, Android’s ConnectivityMan...
The Linux kernel handles networking in a similar way to the SCSI subsystem described in Chapter 3. 计算机通过使用一系列组件来回答这些问题,每个组件负责发送、接收和识别数据的某个方面。 这些组件按照层次分组,堆叠在一起形成一个完整的系统。 Linux内核处理网络的方式与第三章中描述的SCSI子系统类似。
If the host being scanned is a firewall, you will need to review any port address translation rules configured in the firewall/router and consult your firewall documentation. Identify the processes listening on the ports that the Acunetix network scan has identified. You will need to close thes...
