Network Configuration Files
As previously stated, five network configuration files can be modified to make changes to basic network interaction of your system:
• /etc/hosts—A listing of addresses, hostnames, and aliases
• /etc/services—Network service and port connections
• /etc/nsswitch.conf—Linux network information service configuration
• /etc/resolv.conf—Domain Name Service (DNS) domain (search) settings
• /etc/host.conf—Network information search order (by default, /etc/hosts and then DNS)
After these files are modified, the changes are active. As with most configuration files, you can add comments with a hash mark (#) preceding the comment. All these files have man pages, where you can find more information.
