sys-unconfig(1M) 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 configuration to an "as-manufactured" state, ready to be reconfigured again. The sys- tem's configuration consists of hostname, Network Information Service (NIS) domain name, timezone, IP address, IP subnet mask, and root pass- word. This operation is the inverse of those performed by the sysid- net(1M), sysidns(1M), and sysidsys(1M) programs run at boot. See sysid- tool(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 Network Infor- mation 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 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 applica- tions are defined by prior executions of a sysidconfig -a appli- cation. (See sysidconfig(1M)). When sys-unconfig is run, all sys- tem configuration applications 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. When sys-unconfig is finished, it performs a system shutdown. sys-un- config is a potentially dangerous utility and can only be run by the super user.
