1.hosts文件,路径:/etc/hosts,此文间是在网络上使用的,用于解析计算机名称和IP地址的映射关系,功能相当于windows下面的c:\windows\system32\drivers\etc\hosts文件,如果想使用计算机名称来访问对方的主机,需要把对方计算机的名称和IP地址写到本机的hosts文件中 2.network文件,路径:/etc/sysconfig/network,此文件是针对本计算机的,是给计算机起的一个名字,是计算机的一个标识.可以使用uname -n 命令来查看

Linux comes with a host based firewall called Netfilter. According to the official project site: netfilter is a set of hooks inside the Linux kernel that allows kernel modules to register callback functions with the network stack. A registered callba

Network Connectivity 1. Important terminologies 1) Link 设备连接的连线.Link本身既可以是有线的,也可以是无线的. 2) Node 设备.电脑,笔记本电脑,手机都可以是Node. 3) Point-to-point 连接的设备只有两个. 4) Multiple access 连接的设备两个以上.多个设备同时去存取的这样一个Link. 5) Switched Network -> Circuit Switched 通讯之前线路必须建立起来.
