Networking Setup

(Home >> Networking Setup)

This section of the WHM interface allows you to configure your server for use on the Internet.

• Change Hostname — This interface allows you to change your server's hostname.
  

  Note:

  Whenever you change the server's hostname, you must use one of the following methods: 

  • Enter the new hostname in the Setup Networking section of WHM's Initial Setup Wizard interface.
  • Use WHM's Change Hostname interface (Home >> Networking Setup >> Change Hostname).
  • Call WHM API 1's sethostname function.
  • Run the /usr/local/cpanel/bin/set_hostname utility as the root user.

  These methods ensure that all of the necessary system and service changes occur.

  Important:

  If you update your hostname, the system blocks user access to the following interfaces and services:

  • Horde Webmail
  • Calendars and Contacts (CalDAV/CardDAV)

  The system restores access to these interfaces and services after the hostname update completes. For more information, read our Interface Lock Scripts documentation.

• Resolver Configuration — This interface allows you to use a configuration wizard to edit the /etc/resolv.conf file. This file contains the nameservers that your server will query in order to resolve domain names into IP addresses.
