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 bootparams 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 running
       system.

       If the machine's network configuration is delivered by the DHCP protocol, 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 running
       system.

EXAMPLES

       Example 1: Syntax

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

       myhost

NAME

       uname - get name of current operating system

SYNOPSIS

       #include <sys/utsname.h>

       int uname(struct utsname *name);

DESCRIPTION

       The uname() function stores information identifying the current operating system in the structure pointed to by name.

       The uname() function uses the utsname structure, defined in <sys/utsname.h>, whose members include:

       char    sysname[SYS_NMLN];
       char    nodename[SYS_NMLN];
       char    release[SYS_NMLN];
       char    version[SYS_NMLN];
       char    machine[SYS_NMLN];

       The  uname()  function returns a null-terminated character string naming the current operating system in the character array sysname. Simi-
       larly, the nodename member contains the name by which the system is known on a communications network.  The  release  and  version  members
       further identify the operating system. The machine member contains a standard name that identifies the hardware on which the operating sys-
       tem is running.

RETURN VALUES

       Upon successful completion, a non-negative value is returned. Otherwise, -1 is returned and errno is set to indicate the error.

ERRORS

       The uname() function will fail if:

       EFAULT	       The name argument points to an illegal address.
