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  con-
      figuration to an "as-manufactured" state, ready to be recon-
      figured again. The system's configuration consists of  host-
      name,   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:
 
         +  Saves  current  /etc/inet/hosts  file  information  in
            /etc/inet/hosts.saved.
 
         +  If the current  /etc/vfstab file contains   NFS  mount
            entries,     saves    the    /etc/vfstab    file    to
            /etc/vfstab.orig.
 
         +  Restores the default /etc/inet/hosts file.
 
         +  Removes      the       default       hostname       in
            /etc/hostname.interface  files for all interfaces con-
            figured when this command is run.  To determine  which
            interfaces  are configured, run the command 'ifconfig-
            a'.  The  /etc/hostname.interface files  corresponding
            to  all of the interfaces listed in the resulting out-
            put,  with the exception  of  the  loopback  interface
            (lo0), will be removed.
 
         +  Removes the default domainname in /etc/defaultdomain.
 
         +  Restores the timezone to PST8PDT in /etc/TIMEZONE.
 
         +  Disables the Network  Information  Service  (NIS)  and
            Network  Information Service Plus (NIS+) if either NIS
            or NIS+ was configured.
 
         +  Removes the entries for this host in /etc/net/*/hosts.
 
         +  Removes the file /etc/inet/netmasks.
 
         +  Removes the file /etc/defaultrouter.
 
         +  Removes the password set for root in /etc/shadow.

         +  Removes the file /etc/.rootkey.
 
         +  Executes 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.
 
         +  Removes the file /etc/resolv.conf.
 
         +  Disables          LDAP           by           removing
            /var/ldap/ldap_client_cache,
            /var/ldap/ldap_client_file,
            /var/ldap/ldap_client_cred,                        and
            /var/ldap/cachemgr.log.
 
      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.
