Files for network configuration
There are many files for configuring network. These are: /etc/hosts, /etc/host.conf, and /etc/resolv.conf. Many other new configuration files are stored in /etc/sysconfig directory.
/etc/hosts file
If no DNS server is present on the network, this file is still useful in resolving the hostnames. It is very simple file. Each line comprises of an IP address, a fully qualified domain name (FQDN) and optional hostname. Example of one of the entry is shown as below:
192.168.1.72 linuxserver72.mydomain.com linuxserver72
/etc/host.conf
We have two databases of IP addresses and hostnames: 1. DNS servers and 2. /etc/hosts. The searching order is determined by /etc/host.conf file. This file contains only one line, which is as follows:
order hosts,bind
This line tells the Linux system to search for the correct IP address in /etc/hosts file first and then search bind i.e. the DNS server. Here we also can include NIS, in above list.
