sys-unconfig(1M)
NAME
sys-unconfig − undo a system’s configuration
SYNOPSIS
/usr/sbin/sys-unconfig
AVAILABILITY
SUNWinst
DESCRIPTION
sys-unconfig packs up a machine to make it ready to be configured again.
It restores a system’s configuration to an “as-manufactured” state. A 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, sysidnis, and sysidsys programs run at boot.
sys-unconfig does the following:
• Restores the default /etc/inet/hosts file.
• Removes the default hostname in /etc/hostname.??[0-9] and /etc/nodename.
• 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 password set for root in /etc/shadow.
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.
