NAME

       sys-unconfig - undo a system's configuration

SYNOPSIS

       /usr/sbin/sys-unconfig

DESCRIPTION

       The  sys-unconfig  command  is  used to restore a system's configuration to an "as-manufactured" state, ready to be reconfigured again. The
       system's configuration consists of hostname, Network 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), sysidns(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	  If the current /etc/vfstab file contains NFS mount entries, saves the /etc/vfstab file to /etc/vfstab.orig.

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

	   o	  Removes the default hostname in /etc/hostname.interface files for all interfaces configured when this command is run. To  deter-
		  mine	which  interfaces  are configured, run the command 'ifconfig-a'. The /etc/hostname.interface files corresponding to all of
		  the interfaces listed in the resulting output, with the exception of the loopback interface (lo0), will be removed.

	   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 Network Information Service Plus (NIS+) if either NIS or NIS+ was configured.

	   o	  Removes the file /etc/inet/netmasks.

	   o	  Removes the file /etc/defaultrouter.

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

	   o	  Removes the file /etc/.rootkey.

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

	   o	  Removes the file /etc/resolv.conf.

	   o	  Removes the file /etc/sysidcfg.

	   o	  Disables   LDAP   by	 removing   /var/ldap/ldap_client_cache,   /var/ldap/ldap_client_file,	 /var/ldap/ldap_client_cred,   and
		  /var/ldap/cachemgr.log.

	   o	  Regenerates keys for sshd(1M).

       When sys-unconfig is finished, it performs a system shutdown. sys-unconfig is a potentially dangerous utility and can only be  run  by  the
       super user.
