NAME

setup − initialize system for first user

SYNOPSIS

setup

DESCRIPTION

The setup command, which is also accessible as a login by the same name, allows the first user to be established as the owner of the machine. 

The user can then set the date, time and time zone of the machine. 

The user can then set the node name of the machine. 

The user can then protect the system from unauthorized modification of the machine configuration and software by giving passwords to the administrative and maintenance functions.  Normally, the first user of the machine enters this command through the setup login, which initially has no password, and then gives passwords to the various functions in the system.  Any that the user leaves without password protection can be exercised by anyone. 

The user can then give passwords to system logins such as root, bin, etc.  (provided they do not already have passwords).  Once given a password, each login can only be changed by that login or root. 

Finally, the user is permitted to add the first logins to the system, usually starting with his or her own. 

INTERNATIONAL FUNCTIONS

With setup, the time zone can be changed only to the zones in the time zone menu displayed by setup.  Other time zones should be specified using the environment variable TZ in the file /etc/TIMEZONE. 

SEE ALSO

passwd(1),timezone(4). 

DIAGNOSTICS

The passwd(1) command complains if the password provided does not meet its standards. 

NOTES

If the setup login is not under password control, anyone can put passwords on the other functions.
