o All devices on an Ethernet network have a Media Access Control (MAC) address, sometimes called a hardware address. This address is independent of a host’s IP address, and it is unique to the host’s Ethernet network (but not necessarily a larger software network such as the Internet)....
The other problem with the traditional name server setup is that it can be particularly inflexible if you want to be able to look up names on your local network without messing around with a lot of network configuration. For example, if you set up a network appliance on your network, you...
/etc/sysconfig/network-scripts/ifcfg-name文件存储连接的持久配置,其中name是连接的名称。当连接名中有空格时,文件名中的空格将被替换为下划线。如果需要,这个文件可以手工编辑。 nmcli程序从shell提示符创建和编辑连接文件。 查看组网信息,可以通...
