setuname

setuname(1M)						  System Administration Commands					      setuname(1M)

NAME

       setuname - change machine information

SYNOPSIS

       setuname [-t] [-n node] [-s name]

DESCRIPTION

       The  setuname  utility  changes the parameter value for the system name and node name. Each parameter can be changed using setuname and the
       appropriate option.

       Either or both the -s and -n options must be given when invoking setuname.

       The system architecture may place requirements on the size of the system and network node name. The command will issue a fatal warning mes-
       sage and an error message if the name entered is incompatible with the system requirements.

OPTIONS

       The following options are supported:

       -n node	       Changes	the node name. node specifies the new network node name and can consist of alphanumeric characters and the special
		       characters dash, underbar, and dollar sign.

       -s name	       Changes the system name. name specifies new system name and can consist of alphanumeric characters and the special  charac-
		       ters dash, underbar, and dollar sign.

       -t	       Temporary change. No attempt will be made to create a permanent change.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |

       +-----------------------------+-----------------------------+

SEE ALSO

       attributes(5)

NOTES

       setuname  attempts  to  change the parameter values in two places: the running kernel and, as necessary per implementation, to cross system
       reboots. A temporary change changes only the running kernel.
