Maintenance Commands				 sys-unconfig(1M)

NAME
     sys-unconfig - undo a system's configuration

SYNOPSIS
     /usr/sbin/sys-unconfig

DESCRIPTION
     sys-unconfig packs	up a machine to	make it	ready to be  con-
     figured again.

     It	restores a system's configuration to an	"as-manufactured"
     state.   A	system's configuration consists	of hostname, Net-
     work Information Service (NIS)  domain  name,  timezone,  IP
     address,  IP subnet mask, and root	password.  This	operation
     is	the inverse  of	 those	performed  by  the  sysidnet(1M),
     sysidnis(1M),  and	 sysidsys(1M)  programs	run at boot.  See
     sysidtool(1M).

     sys-unconfig does the following:

     o	  Saves	 current  /etc/inet/hosts  file	 information   in
	  /etc/inet/hosts.saved.

     o	  Restores the default /etc/inet/hosts file.

     o	  Removes the default hostname	in  /etc/hostname.??[0-9]
	  and /etc/nodename.

     o	  Removes the default domainname in /etc/defaultdomain.

     o	  Restores the timezone	to PST8PDT in /etc/TIMEZONE.

     o	  Disables the Network Information Service (NIS) and Net-
	  work	Information  Service Plus (NIS+) if either NIS or
	  NIS+ was configured.

     o	  Removes the entries for this host in /etc/net/*/hosts.

     o	  Removes the file /etc/inet/netmasks.

     o	  Removes the password set for root in /etc/shadow.

     o	  Removes the file /etc/.rootkey.

     o	  Execute all system configuration  applications.   These
	  applications	are  defined  by  prior	 executions  of	a
	  sysidconfig  -a  application.	  (See	sysidconfig(1M)).
	  When	sys-unconfig  is  run,	all  system configuration
	  applications are passed one argument,	-u.

     When sys-unconfig is finished, it performs	 a  system  shut-
     down.

     sys-unconfig is a potentially dangerous utility and can only
     be	run by the super-user.
