For example, if you’re sending data from Host A to Host B, as shown in Figure 9-1, your bytes leave the application layer on Host A and travel through the transport and network layers on Host A; then they go down to the physical medium, across the medium, and up again through the...
All the people who belong to the networking background know that an IP address acts as a unique identifier of the devices within a network. Therefore, we must know the IP addresses of the devices within a network to enable smooth network communication. Today’s article will focus on the dif...

yum list: 列出所有可用的软件包 特点 支持软件包组安装(如安装一个功能所需的多组软件包) 依赖解决能力较好,但相较于DNF稍显落后 3、DNF (Dandified Yum) DNF是YUM的下一代版本,适用于RHEL 8+、CentOS 8+、Fedora等发行版,是YUM的替代工具。 常用命令 dnf update: 更新软件包 dnf install <包名>: ...
/etc/network/interfaces文件记录了所有的静态配置信息。内核在引导的时候,会自动启动标志为“auto”的设备,例如: auto lo auto eth0 auto wlan0 而如果设备标志为“allow-hotplug”,那么内核在检测到热插拔事件的时候,也会自动启动。例如: allow-hotplug lo ...
