Administration Web Server

The Administration Web Server serves the administration pages through which the Netra administration modules are configured. To protect access to the administration web server from unauthorized users, access to the web server is protected through a password (mandatory), and an access list (optional). If an access list is specified, connections from machines that are not on the list are refused. Connections from machines on the list are permitted access, provided the user knows the password.

To Change the Administration Password

1. From the Main Administration page, under "Security Administration," click Administration Web Server.

   The Administration Web Server Administration page is displayed.

2. Click Change Administration Password.

   The Administration Password page is displayed.

3. Complete the form using the information in the following table.

   Table 8-1 Web Server Password Administration

   Option	Description
   Current Administration Password	Type existing administration password. The administration password for an unconfigured Netra system is setup. A password can be a combination of any characters.
   New Administration Password	Type a new password to access your Netra server. The password is not echoed as you type it. If you change the existing password, you must re-authenticate the browser connection using the new password you provide.
   Re-enter New Administration Password	Type the new administration password. Because the password is not echoed as you type it the first time, you must verify it by typing it a second time.

To Modify Host Access Control

The Host Access Control enables you to set the hosts that can access the administration web server. There are two possible access modes: Administration access can be granted to all hosts, or access can be restricted to a specified list of hosts and networks (an access control list). The Netra system is always allowed administration access, even when it is not specified in the access control list. If security is important, set restrictions, particularly when the Netra system is connected to the Internet.

1. From the Main Administration page, under "Security Administration," click Administration Web Server.

   The Administration Web Server Administration page is displayed.

2. Click Modify Host Access Control.

   The Host Access Administration page is displayed.

3. Complete the form using the following table for reference.

   Table 8-2 Host Access Control Administration

   Option	Description

UDP-based services, which are not connection-oriented, may linger after the client has disconnected. Reboot the Netra j server after modifying the access control to these services.
