nodename(4)                      File Formats                      nodename(4)



NAME
       nodename - local source for system name

SYNOPSIS
       /etc/nodename

DESCRIPTION
       When  a  machine is standalone or its IP address is configured locally,
       the /etc/nodename file contains the system  name.  By  convention,  the
       system  name is the same as the hostname associated with the IP address
       of the primary network interface, for example, hostname.hme0.

       If the machine's network configuration is delivered by  the  RPC  boot-
       params protocol, the /etc/nodename file is not used, as the system name
       is delivered by the remote service.

       Given a system name value, regardless  of  source,  the  uname  utility
       invoked  with  the -S option is used to set the system name of the run-
       ning system.

       If the machine's network configuration is delivered by the DHCP  proto-
       col,  the  /etc/nodename  file is used only if the DHCP server does not
       provide a value for the Hostname option (DHCP standard option code 12).

       A system name configured in /etc/nodename should be unique  within  the
       system's  name  service domain in order to ensure that any network ser-
       vices provided by the system will operate correctly.

       Given a system name value, regardless  of  source,  the  uname  utility
       invoked  with  the -S option is used to set the system name of the run-
       ning system.

EXAMPLES
       Example 1: Syntax

       The syntax for nodename consists of a single line containing  the  sys-
       tem's name. For example, for a system named myhost:

       myhost
