correspondence. The number of early Internet computers is low, and the stand-alone hosts file is sufficient to store all networked computers. But with the development of the Internet, this is far from enough. A distributed DNS system is then present. The DNS server provides a similar IP address to the corresponding domain name. Specifically, man hosts can view relevant information.The Linux system queries the/etc/hosts file before issuing a domain na

/sysconfig/network is indeed a hostname configuration file, and the value of hostname is associated with the hostname in the configuration file, but there is no certainty that the hostname value comes from the kernel parameter/proc/ Sys/kernel/hostname, if I

(2) function, and hostname -a–d–f, the-i command is called the gethostbyname (3) function,the difference between gethostname (2) and gethostbyname (3) is the network of gethostbyname (3), So the gethostbyname (3) function needs to ask the/etc/nsswitch.conf and/etc/host.conf files to determine whether it is from the/etc/sysconfig/network configuration file or from the/etc/ The hosts configuration file reads the information. Therefore, the configuratio

Linux sir.org; What is the host name used? In a LAN, each machine has a host name for easy distinction between the host and the host, you can set a host name for each machine, to facilitate mutual access in a way that is easy to remember. For example, we can name each machine based on its functions in the LAN. Configuration file related to the Host Name:/etc/hosts; 2. Linux host name configuration file; Mo

early days, and the hosts file on a single machine was enough to store all the computers on the Internet. However, with the development of the Internet, this is far from enough. As a result, a distributed DNS system emerged. The DNS server provides a similar IP address to the corresponding domain name. Man hosts is supported.The Linux system will query the/etc/hosts file before sending a domain name resolution request to the DNS server. If there is a
