NAME

6       sys-unconfig - undo a system's configuration

SYNOPSIS

DESCRIPTION

13       The sys-unconfig command is used to restore a system's configuration to
14       an "as-manufactured" state, ready to be reconfigured  again.  The  sys‐
15       tem's  configuration  consists of hostname, Network Information Service
16       (NIS) domain name, timezone, IP address, IP subnet mask, and root pass‐
17       word.  This  operation  is the inverse of those performed by the sysid‐
18       net(1M), sysidns(1M), and sysidsys(1M) programs run at boot. See sysid‐
19       tool(1M).
20
21
22       sys-unconfig does the following:
23
24           o      Saves    current   /etc/inet/hosts   file   information   in
25                  /etc/inet/hosts.saved.
26
27           o      If the current /etc/vfstab file contains NFS mount  entries,
28                  saves the /etc/vfstab file to /etc/vfstab.orig.
29
30           o      Restores the default /etc/inet/hosts file.
31
32           o      Removes  the  default  hostname  in  /etc/hostname.interface
33                  files for all interfaces configured  when  this  command  is
34                  run.  To  determine which interfaces are configured, run the
35                  command 'ifconfig-a'. The /etc/hostname.interface files cor‐
36                  responding  to all of the interfaces listed in the resulting
37                  output, with the exception of the loopback interface  (lo0),
38                  will be removed.
39
40           o      Removes the default domainname in /etc/defaultdomain.
41
42           o      Restores the timezone to PST8PDT in /etc/TIMEZONE.
43
44           o      Disables  the  Network Information Service (NIS) and Network
45                  Information Service Plus (NIS+) if either NIS  or  NIS+  was
46                  configured.
47
48           o      Removes the file /etc/inet/netmasks.
49
50           o      Removes the file /etc/defaultrouter.
51
52           o      Removes the password set for root in /etc/shadow.
53
54           o      Removes the file /etc/.rootkey.
55
56           o      Executes all system configuration applications. These appli‐
57                  cations are defined by prior executions of a sysidconfig  -a
58                  application.  (See  sysidconfig(1M)).  When  sys-unconfig is
59                  run, all system configuration applications  are  passed  one
60                  argument, -u.
61
62           o      Removes the file /etc/resolv.conf.
63
64           o      Removes the file /etc/sysidcfg.
65
66           o      Disables   LDAP   by  removing  /var/ldap/ldap_client_cache,
67                  /var/ldap/ldap_client_file, /var/ldap/ldap_client_cred,  and
68                  /var/ldap/cachemgr.log.
69
70           o      Regenerates keys for sshd(1M).
71
72
73       When  sys-unconfig  is  finished,  it  performs a system shutdown. sys-
74       unconfig is a potentially dangerous utility and can only be run by  the
75       super user.
