ONFIGURATIONS
At present, the system supports the following five kinds of welcome information.
■
shell banner, also called session banner, displayed when a non Modem user
enters user view.
■
incoming banner, also called user interface banner, displayed when a user
interface is activated by a Modem user.
■
login banner, welcome information at login authentications, displayed when
password and scheme authentications are configured.
■
motd banner, welcome information displayed before authentication.
■
legal banner, also called authorization information. The system displays some
copyright or authorization information, and then displays the legal banner
before a user logs in, waiting for the user to confirm whether to continue the
authentication or login. If entering Y or pressing the
Enter key, the user enters
the authentication or login process; if entering N, the user quits the
authentication or login process. Y and N are case insensitive.
Configuring a banner
When you configure a banner, the system supports two input modes. One is to
input all the banner information right after the command keywords. The start and
end characters of the input text must be the same but are not part of the banner
information. In this case, the input text, together with the command keywords,
cannot exceed 510 characters. The other is to input all the banner information in
multiple lines by pressing the
Enter key. In this case, up to 2000 characters can be
input.
The latter input mode can be achieved in the following three ways:
■
Press the Enter key directly after the command keywords, and end the setting
with the % character. The Enter and % characters are not part of the banner
information.
■
Input a character after the command keywords at the first line, and then press
the
Enter key. End the setting with the character input at the first line. The
character at the first line and the end character are not part of the banner
information.
■
Input multiple characters after the command keywords at the first line (with
the first and last characters being different), then press the
Enter key. End the
setting with the first character at the first line. The first character at the first line
and the end character are not part of the banner information.
