SULOGIN(8) Maintenance Commands and Procedures SULOGIN(8)

NAME

sulogin - access single-user mode

SYNOPSIS

sulogin

DESCRIPTION

The sulogin utility is automatically invoked by init when the system is
first started. It prompts the user to type a user name and password to
enter system maintenance mode (single-user mode) or to type EOF
(typically CTRL-D) for normal startup (multi-user mode). The user should
never directly invoke sulogin. The user must have the
solaris.system.maintenance authorization.


The sulogin utility can prompt the user to enter the root password on a
variable number of serial console devices, in addition to the traditional
console device. See consadm(8) and msglog(4D) for a description of how to
configure a serial device to display the single-user login prompt.

FILES

/etc/default/sulogin

Default value can be set for the following flag:

PASSREQ

Determines if login requires a password. Default is PASSREQ=YES.


/etc/default/login

Default value can be set for the following flag:

SLEEPTIME

If present, sets the number of seconds to wait before login
failure is printed to the screen and another login attempt is
allowed. Default is 4 seconds. Minimum is 0 seconds. Maximum is
5 seconds.

Both su(8) and login(1) are affected by the value of SLEEPTIME.

NOTES

By default, the root user has all authorizations.


Granting the solaris.system.maintenance authorization to the Console User
Rights Profile may have an undesirable side effect of granting the
currently logged in user maintenance mode access. The
solaris.system.maintenance authorization should be directly granted to
appropriate users rather than through the Console User Rights Profile.
