System Administration Commands sys-unconfig(1M)
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:
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 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 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 Net-
work 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.

System Administration Commands sys-unconfig(1M)
o 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 applica-
tions are passed one argument, -u.
o Removes the file /etc/resolv.conf.
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 shut-
down. sys-unconfig is a potentially dangerous utility and
can only be run by the super user.
