Chapter 9 Accessing and Monitoring PIX Firewall

Configuring PIX Firewall Banners

This website provides a downloadable file with instructions for using it to remove the lines in the

PIX Firewall configuration that enable authentication and cause the lockout problem.

You can encounter a different type of lockout problem if you use the aaa authorization command

tacacs_server_tag command and you are not logged as the correct user. For every command you type,

the PIX

Firewall will display the following message:

Command Authorization failed

This occurs because the TACACS+ server does not have a user profile for the user account that you used

for logging in. To prevent this problem, make sure that the TACACS+ server has all the users configured

with the commands that they can execute. Also make sure that you are logged in as a user with the

required profile on the TACACS+ server.

Configuring PIX Firewall Banners

PIX Firewall Version 6.3 introduces support for “Message-of-the-Day” (MOTD), EXEC, and login

banners, similar to the same feature in Cisco IOS software. The size of banners is only limited by

available system memory or Flash memory.

To configure a banner, enter the following command:

banner {exec|login|motd} text

Replace text with the string that you want the system to display. Spaces are allowed but tabs cannot be

entered using the CLI. You can dynamically add the host name or domain name of the PIX

Firewall by

including the strings $(hostname) and $(domain) in the string.

Use the exec option to display a banner before the enable prompt is displayed. Use the login option to

display the banner before the password login prompt when accessing the PIX

Firewall using Telnet. Use

the motd option to display a message-of-the-day banner.

To configure a banner including multiple lines, enter the banner command once for each line in the

banner.

To display the current banner, enter the following command:

show banner {exec|login|motd}

To remove a specific banner, enter the following command:

no banner {exec|login|motd}

To clear all banners, enter the following command:

clear banner
