sys-unconfig - undo a system's configuration




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 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. 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 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. SunOS 5.8 Last change: 16 Jun 2000 1 Maintenance Commands sys-unconfig(1M) o Removes the file /etc/.rootkey. 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 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 shut- down. sys-unconfig is a potentially dangerous utility and can only be run by the super user.
