Setting Up User Login Controls
You can set up login controls to make it more difficult for hackers to
access the PXE and the devices connected to it. You can arrange to lock
persons out after a specified number of failed logins, limit the number of
persons who log in using the same user name at the same time, and
force users to create strong passwords.
Enabling User Blocking
User blocking determines how many times a user can attempt to log in to
the PXE and fail authentication before the user is blocked.
Note that this function applies only to local authentication instead of
authentication through external AA servers.
Note: If any user blocking event occurs, you can unblock that user
manually by using the "unblock" CLI command via a local connection.
See
Unblocking a User (on page 315).
To enable user blocking:
1. Choose Device Settings > Security > Login Settings. The Login
Settings dialog appears.
2. Locate the User Blocking section.
3. To enable the user blocking feature, select the "Block user on login
failure" checkbox.
4. Type a number in the "Maximum number of failed logins" field. This
is the maximum number of failed logins the user is permitted before
the user is blocked from accessing the PXE device.
5. To determine how long the user's login is blocked, select the desired
length of time from the drop-down list in the "Block timeout" field. The
following describes available options.
 Infinite: This option sets no time limit on blocking the login.
 X min: This type of option sets the time limit to X minutes, where
X is a number.
