 hostname(1)                                                     hostname(1)

 NAME    [Toc]    [Back]
      hostname - set or display name of current host system

 SYNOPSIS    [Toc]    [Back]
      hostname [name_of_host]

 DESCRIPTION    [Toc]    [Back]
      The hostname command displays the name of the current host, as given
      in the gethostname() system call (see gethostname(2)).  Users who have
      appropriate privileges can set the hostname by giving the argument
      name_of_host; this is usually done in the startup script
      /sbin/init.d/hostname.  The name_of_host argument is restricted to
      MAXHOSTNAMELEN characters as defined in <sys/param.h>.

      The system might be known by other names if networking products are
      supported.  See the node manager documentation supplied with your

 WARNINGS    [Toc]    [Back]
      If the name_of_host argument is specified, the resulting host name
      change lasts only until the system is rebooted.  To change the host
      name permanently, run the special initialization script
      /sbin/set_parms (see Using Your HP Workstation).

      Many types of networking services are supported on HP-UX, each of
      which uses a separately assigned system name and naming convention.
      To ensure predictable system behavior, it is essential that system
      names (also called host names or node names) be assigned in such a
      manner that they do not create conflicts when the various networking
      facilities interact with each other.

      The system does not rely on a single system name in a specific
      location, partly because different services use dissimilar name
      formats as explained below.  The hostname and uname commands assign
      system names as follows:

      |Node Name     |Command       |name Format    |Used By                |
      |Internet name |hostname name |sys[.x.y.z...] |ARPA and NFS Services  |
      |UUCP name     |uname -S name |sys            |uucp, related programs |
      +--------------+--------------+---------------+-------- --------------+

      where sys represents the assigned system name.  It is strongly
      recommended that sys be identical for all commands and locations and
      that the optional .x.y.z... follow the specified notation for the
      particular ARPA/NFS environment.

      Internet names are also frequently called host names or domain names
      (which are different from NFS domain names).  Refer to hostname(5) for
      more information about Internet naming conventions.

 hostname(1)                                                     hostname(1)

      Whenever the system name is changed in any file or by the use of any
      of the above commands, it should also be changed in all other
      locations as well.  Other files or commands in addition to those above
      (such as /etc/uucp/Permissions if used to circumvent uname, for
      example) may contain or alter system names.  To ensure correct
      operation, they should also use the same system name.

      System names are normally assigned by the /sbin/init.d/hostname script
      at start-up, and should not be altered elsewhere.
