Introduction
Cisco's PIX Firewall Manager (PFM) lets you administer one or more PIX Firewall units, view syslog messages, and define customized alarms for each type of syslog message. You can use the PIX Firewall Manager to view, add, and modify the configuration of each PIX Firewall unit.
This version of PIX Firewall Manager does not support use of the new version 4.4 features, but will work with features that are common to both versions. PIX Firewall Manager version 4.3(2)B does not support the following version 4.4(1) features:
1 AAA—either specifying an authentication server or use of authentication, authorization, or accounting.
2 FDDI network interface cards
3 ActiveX filtering
4 Private Link age duration changes
If you are using version 4.4(1), features not supported by PIX Firewall Manager version 4.3(2)B can be set from the PIX Firewall command line interface.
PIX Firewall Manager software includes these components:
•Management Server—a Windows NT service that runs in the background and receives requests from the Management Client, sends them to the specified PIX Firewall unit, and then passes the PIX Firewall's responses back to the Management Client. The Management Server starts automatically when the installation completes. An icon for the server does not display in the task bar.
•Management Client—a Java applet that you access from the network browser. The Management Client network browser must be Java 1.02 compliant. Refer to "Management Client Requirements" for more information.
PIX Firewall Manager provides two access levels: user-level with read-only (non-modifying) access and administrator-level with read and write access.
Diskettes for installing PIX Firewall Manager are provided in the PIX Firewall accessory kit.
If you are upgrading from a previous version of PIX Firewall Manager software, refer to the Configuration Guide for the PIX Firewall Version 4.3, which is included with your PIX Firewall accessory kit. This document has instructions for downloading software from Cisco Systems, Inc.
PIX Firewall Manager can be installed and uninstalled on Workstation and Server versions of Windows NT 4.0.
System Requirements
The following sections describe system requirements.
Windows NT Requirements
The Windows NT system on which you install the Management Server requires the following:
•Windows NT Workstation or Windows NT Server version 4.0 or later with Service Pack 3.
•The Windows NT system must contain a Pentium processor and at least 32 MB RAM.
•TCP/IP must be enabled and the system's IP address must not be dynamically allocated, such as with DHCP.
•The Windows NT system must be on the PIX Firewall's inside network.
•Users must be part of the PIX Admins or PIX Users groups on the Windows NT system. These two user groups and two temporary user accounts are created by the PIX Firewall Manager installation program. Refer to "Limiting Access to the Management Client" for more information on how to add users to these groups.
PIX Firewall Requirements
Note Each PIX Firewall you manage must have been configured with the PIX Firewall telnet command or PIX Firewall Setup Wizard to permit the Management Server to access the PIX Firewall. The PIX Firewall Setup Wizard is not available in version 4.4
All PIX Firewall units managed by PIX Firewall Manager version 4.3(2) must be running PIX Firewall software version 4.3(2), version 4.4(1) or later. To check the version of the PIX Firewall software, go to the PIX console and enter the show version command.
If you intend to manage PIX Firewall units on the outside network, each foreign unit must run Private Link and at least one firewall on the local network must also run Private Link. The local PIX Firewall must be configured to communicate with the foreign Private Link firewalls.
You must have console access to each local and foreign PIX Firewall you manage in order to perform the configuration required to run the PIX Firewall Manager. If you are managing remote firewalls, work with the site administrator to get the PIX Firewall to communicate with PIX Firewall Manager.
To configure each PIX Firewall unit from the Setup Wizard, follow the instructions in the Quick Installation Guide for the PIX Firewall Version 4.3. The PIX Firewall Setup Wizard is not available in version 4.4.
To configure each PIX Firewall unit from the command line, enter these commands at the PIX Firewall console:
Step 1 enable—to enter privileged mode. When prompted, enter the privileged mode password. The default is no password and you can press the Enter key at the prompt.
Step 2 configure terminal—to enter configuration mode.
Step 3 nameif—to specify the name or security level of the outside or optional third interface on the PIX Firewall. The inside interface cannot be renamed or given a different security level. Each security level must be a unique number between 0 and 99.
Step 4 interface—to set options for the Ethernet or Token Ring network interfaces.
Step 5 ip address—to assign IP addresses and network masks to each interface.
Step 6 telnet—to let the PIX Firewall communicate with the PIX Firewall Manager:
: Telnet for PIX Firewall Manager
telnet Windows_NT_IP_Address 255.255.255.255
Replace Windows_NT_IP_Address with the IP address of the Windows NT system.
Add the comment before the telnet statement to ensure that the next person configuring the firewall knows the purpose of this telnet statement.
Step 7 link and linkpath—if you are managing remote PIX Firewall units, configure each for Private Link access. Refer to Chapter 2, "Configuring the PIX Firewall," in the Configuration Guide for the PIX Firewall Version 4.3 for information on configuring Private Link, and Chapter 5, "Command Reference," to view the link command page for more information.
Step 8 write memory—save the configuration in Flash memory.
All commands are described in the Configuration Guide for the PIX Firewall Version 4.3 supplied in your PIX Firewall accessory kit.

•Generate the initial inbound and outbound connection statements in the PIX Firewall configuration using the Tasks button in the Management Client to access a series of dialog boxes.
Note The Tasks button generates statements in the PIX Firewall configuration that allow connections to or from hosts on internal (protected) networks. If you have additional configuration requirements, such as access control for outbound connections and user authentication or authorization, other configuration commands apply. Refer to the Configuration Guide for the PIX Firewall Version 4.3 for detailed configuration information.
•Avoid conflicts between Open Systems Solutions Private I and PIX Firewall Manager installed on the same system using the SYSLOG Redirection button on the SYSLOG Notification Settings tab. The SYSLOG Redirection button copies syslog event information received from port 514 to port 515.
•Set the time interval for updating syslog message files using an option in the SYSLOG Notification Settings tab.
•Capture quickly scrolling messages in the SYSLOG Message Window using the Message Snapshot button. The snapshot displays up to 200 lines of messages in a separate window. To display the SYSLOG Message Window, select the SYSLOG Notification Settings tab and change the Immediate SYSLOG Message setting to ON.
Refer to the Configuration Guide for the PIX Firewall Version 4.3 for detailed information about PIX Firewall system features.
Installation Notes
1 Each PIX Firewall you wish to manage must be running PIX Firewall version 4.3(2), 4.4(1) or later.
2 Each PIX Firewall you manage must have previously been configured with the PIX Firewall telnet command or PIX Firewall Setup Wizard to permit access to the PIX Firewall from the PIX Firewall Manager's Management Server. PIX Firewall Setup Wizard is not available in version 4.4.
3 A PIX Firewall Syslog Server (PFSS) is available for logging PIX Firewall event information on a Windows NT system. PFSS provides logging features not available with the PIX Firewall Manager (PFM), such as using TCP for highly reliable message delivery and control. PFM has features not available with PFSS, such as generating reports from syslog information.
The PIX Firewall does not support running both the PFM and PFSS applications at the same time. You must use either PFM or PFSS, but not both. For more information on installing and running PFSS, refer to the Quick Installation Guide for the PIX Firewall Version 4.3.
4 The Windows NT computer running the PIX Firewall Manager Management Client (graphical user interface) must have a network browser that is Java 1.02 compliant. Refer to "Management Client Requirements" for more information.
5 Selecting a menu item (or screen) is indicated by the following convention:
Select screen1>screen2>screen3.
6 The initial PIX Firewall Manager password is set to expire after 42 days. Refer to "Changing Passwords" for more information.
7 PIX Firewall Manager Version 4.3(2) encrypts all communication with the PIX Firewall software version 4.3(2). Managing PIX Firewall units running earlier software versions is not supported.
8 After installation and setup, if you change the IP address of the Windows NT system, you need to update the FIREWALL.HTML file installed on the system. The file is in the JClient\Netscape subdirectory on the Management Server's target directory. In the FIREWALL.HTML file, swap the old IP address with the current IP address, which is only visible from the inside network.
Interface entries can be specified as either IP addresses or domain names; however, you must remember to log on to the management server using the exact entry listed in the FIREWALL.HTML file or an IP address security violation error message can appear. This message indicates the Management Server could not locate the interface specified in the FIREWALL.HTML file, having tried the possible interfaces on the Windows NT computer running the Management Server.
The sections that follow describe other installation topics.
Before Installing
Before installing PIX Firewall Manager, you need to know the following:
•Passwords
•PIX Firewall privileged mode password. This is set by the enable password command at the PIX Firewall console. Once set, the password cannot be viewed and must be obtained from its creator.
•PIX Firewall Telnet password. The default value is cisco, but if this is changed with the PIX Firewall's passwd console command, you must get the password from the PIX Firewall's system administrator because you cannot display this value at the PIX Firewall console.
•Password for a user with Windows NT Administrator privileges.
•Configuration—for each PIX Firewall you manage, you need to configure it as explained in "PIX Firewall Requirements." After configuring the PIX Firewall, determine its inside IP address with the show ip address console command.
•Port number—during installation, you are asked to supply a port number for the PIX Firewall Manager's built-in web server. The default port for this server is 8080. It is very unlikely, but possible, that this port could be in use by another server. If that is the case, pick another port for the web server. To pick a port, view the IANA web site to determine which port is appropriate.
ftp://ftp.isi.edu/in-notes/iana/assignments/port-numbers
•IP address—you need the IP address of the Windows NT system running PIX Firewall Manager. If the computer has more than one network interface and you do not know which one connects to the same network as the PIX Firewall, contact your network administrator.
To view the IP address:
Step 1 Select Start>Settings>Control Panel.
Step 2 Double-click the Network icon.
Step 3 Click the Protocols tab and select TCP/IP Protocols>Properties.
Step 4 When the Microsoft TCP/IP Properties dialog box opens, click the IP Address tab. The IP address appears on the lower part of this tab.
Step 5 If the Obtain an IP address from a DHCP server item is checked, click it to disable it. Then click Specify an IP address and enter an IP address, subnet mask, and default gateway IP address for this system.
Installing PIX Firewall Manager
Note Only users with Windows NT Administrator privileges can run the installer or uninstaller program.
During installation, if a previous version of the PIX Firewall Manager is found, the installation program replaces the old version with the new. To install PIX Firewall Manager:
Step 1 If you used the PIX Firewall Setup Wizard to configure the PIX Firewall with the IP address and network mask of the Windows NT computer running the PIX Firewall Manager, skip to Step 2. If you have not set up the IP address for the Windows NT computer, verify network connectivity before starting by following these steps:
(a) From each PIX Firewall you intend to manage, ping the Windows NT system. Use the PIX Firewall ping inside command. The ping is successful if the "response received" message appears. If the ping is unsuccessful, verify the IP address of the Windows NT system and check the network cabling. For example, if the Windows NT system has an IP address of 192.168.42.42, you would use the following commands from the PIX Firewall to enter privilege mode and run the ping command:
ping inside 192.168.42.42
(b) From the Windows NT system, ping the inside interface of each PIX Firewall. To ping from Windows NT, click the Start menu. Then choose the Run... item and enter the ping command, or select the Programs>Command Prompt and enter the command there. The ping is successful if the "Reply from" message appears. If the ping is unsuccessful, verify the IP address of the inside interface of the PIX Firewall and check the network cabling. For example, if a PIX Firewall has an inside IP address of 192.168.42.54, you would enter this command:
(c) From the Windows NT system, establish a Telnet session with each target PIX Firewall. The Telnet is successful if the "PIX password" prompt appears. The default password is cisco. Enter the password to receive access to the PIX Firewall command prompt. If the Telnet is unsuccessful, go to the PIX Firewall console and use the show telnet command to ensure that the configuration has a telnet command entry for the IP address of the Windows NT system. Refer to "PIX Firewall Requirements" for information on how to enter the PIX Firewall console commands to get to configuration mode, give Telnet access, and store the configuration in Flash memory. For example, if a PIX Firewall has an IP address of 192.168.42.54, enter these commands to access configuration mode, let administrators start Telnet sessions with the PIX Firewall console, and store the configuration in Flash memory:
: Created for PIX Firewall Manager
Step 2 Exit all Windows programs.
Step 3 Log in to the Windows NT system as Administrator or as any user who is a member of the Administrator group or who has Windows NT Administrator privileges.
Step 4 From the Windows NT system, insert the first PIX Firewall Manager diskette in the diskette drive. You can install the software:
•From the Add/Remove Programs icon in the Control Panel, accessed by choosing the Settings item from the Start menu.
•From My Computer by double-clicking the diskette icon and then double-clicking the miniature computer Setup icon.
•By choosing the Run item from the Start menu and entering the starting filename as a:\setup.exe. (If the diskette is in another drive, use that drive letter instead.)
Step 5 Once the installation program starts, you are prompted with a series of dialog boxes. You can simply click Next and the installation will proceed without interruption. Alternately, you can designate an installation directory other than the default.
Step 6 During the installation you are prompted for a port number for the PIX Firewall Manager's built-in web server; use the default, 8080, unless that port is in use already. Any port between 1025 and 64000 can be entered as an alternative. To pick another port, view ftp://ftp.isi.edu/in-notes/iana/assignments/port-numbers to find the ports in use.
The installation program then copies its files and prompts you to insert the second diskette. Insert the diskette and the remaining files are copied.
Step 7 At the last dialog box, click Finish. The Management Server starts automatically.
Step 8 To check whether the Management Server is running, select Start>Settings>Control Panel and double-click the Services icon. Look for the "PIX Firewall Management Server" service name. A server is running if its status appears as Started. If the status field is blank, you may run the server by selecting its name and then clicking Start. If you need to stop the Management Server, refer to the instructions for doing so in "Management Client Requirements."
Step 9 After the software setup completes, change the default passwords of the pixadmin and pixuser users with the Windows NT User Manager program described in the following section, "Changing Passwords."
Changing Passwords
To change passwords for the pixadmin and pixuser default usernames:
Step 1 Select Start>Programs>Administrative Tools (Common)>User Manager. If your Windows NT system is a domain controller, select User Manager for Domains.
Step 2 When the User Manager starts, locate the two users, pixadmin and pixuser in the Username section of the screen.
Step 3 Select the pixadmin username and select User>Properties.
Step 4 In the User Properties dialog box, enter the new password in the Password and Confirm Password fields.
Step 5 In the User Properties dialog box, check Password Never Expires to prevent the password from expiring. If the box is not checked, the password expires after the number of days set in the Account Policy Maximum Password Age configured in the Windows NT system. The default value set during Windows NT system installation is 42 days. Click OK to exit.
Step 6 Select the pixuser username and select User>Properties. Enter the new password in the Password and Confirm Password fields.
Step 7 In the User Properties dialog box, check Password Never Expires to prevent the password from expiring.
Step 8 Click OK to exit and select User>Exit to leave the User Manager.
Limiting Access to the Management Client
You can specify which users can access the Management Client by creating user accounts on the Windows NT system on which PIX Firewall Manager is installed and giving the user either PIX Firewall Manager administrative or read-only access privileges. When the Management Client starts, users enter their login ID and password and, if accepted, they can then run PIX Firewall Manager.
Note Before limiting access to the Management Client, change the default password to a new value as described in the preceding section, "Changing Passwords."
To limit access to the Management Client:
Step 1 Start the User Manager as described in Step 1 in the preceding section, "Changing Passwords." The User Manager dialog box appears. If you want to authorize access for users who already have accounts on the Windows NT system, proceed to Step 2. To add new users to the Windows NT system, select User>New User. Specify the information for the user including the user's login name, full name, and password.
Step 2 To give a user access to the Management Client, locate the Groups area at the bottom of the User Manager dialog box.
Step 3 From the Groups area, if you want users to be able to change PIX Firewall settings, double-click PIX Admins. If you want users only to have read access and no change privileges, double-click PIX Users. The Local Group Properties dialog box then appears.
Step 4 Click Add to add an existing user to the selected group. The Add Users and Groups dialog box appears.
Step 5 From the Names field, select the name of the user you wish to add, click Add, and then click OK to complete adding this user. Control returns to the Local Group Properties dialog box where you can continue adding users. To exit back to the User Manager dialog box, click OK. Then exit User Manager by clicking OK.
Note Do not assign a user to both the PIX Admins and PIX Users groups.

Step 2 When the Services dialog box opens, select the PIX Firewall Management Server item from the Service list. You can stop this service by clicking the Stop button.
Generating and Printing Syslog Reports
The PIX Firewall generates syslog messages for system events, such as security alerts and resource depletion. Syslog messages are stored in log files and can be used to create alerts and reports.
The PIX Firewall Manager provides two ways to view syslog connection information: using the PIX Firewall Management Client graphical user interface, or using a Microsoft Excel macro and data files provided for Microsoft Excel 97. Options for printing reports are available only using Microsoft Excel 97. This section includes the following topics:
•Configuration Requirements
•Viewing Reports
•Troubleshooting Syslog Reporting Problems
Configuration Requirements
Prior to using the Alarm and Report features, you must configure each PIX Firewall to generate syslog messages and send them to a syslog server host, one of which can be the host running the PIX Firewall Manager. The syslog server in the PIX Firewall Manager listens for messages from the PIX Firewall on UDP port 514. Messages are stored in daily log files on the Windows NT computer running the PIX Firewall Manager. The PFM uses the information in the daily log files to generate reports. To configure each PIX Firewall unit from the Management Client, select Admininstrator>SYSLOG to view options for configuring syslog host and message information.
Viewing Reports
To view syslog reports from the PIX Firewall Management Client, follow the instructions for "Navigating the Management Client." From the Management Client, click the Alarm and Report tab to view options for generating reports.
•To view and print syslog reports from the macro, follow the instructions for "Starting the Management Client" to display the PIX Firewall Manager home page. From the home page, follow the instructions on how to log in and generate reports. The procedure for generating and printing syslog reports uses the Microsoft Excel macro REPORT.XLS. To use this file, start the Microsoft Excel application and open the file from within the application. If you try to open the file directly by double-clicking it, the following error message appears:
Cannot open the corresponding DBF file
Note When downloading the files from the web browser, be sure to save all files (report.xls, dns.dbf, monday.dbf, sunday.dbf, and so on) to the same directory on the local drive. After all the files are in the same directory, use Microsoft Excel 97 to open the report.xls file.
Note The macro does not support viewing or printing detailed reports of FTP and HTTP file transfers as provided in reports generated by the PIX Firewall Management Client.
The PIX Firewall Manager saves syslog information in daily log files. For example, PIX Firewall connection information for Monday is saved in the monday.log file. The log files are located in \PIX Firewall Manager\protect\<weekday>.log on the Windows NT computer.
Log files are retained for one week, allowing a separate log file for each day of the week. After one week, daily log files are overwritten, starting with the daily file that was created first. For example, if log files were first started on Monday, the Monday log file will be overwritten in seven days. This also means that you can access a six-day archive of log information for a given day.
Note For reporting purposes, hosts on a perimeter network are considered "outside." When setting up syslog reports from the PIX Firewall Management Client, you must specify "outside" to include the hosts on the perimeter network in the report.
Troubleshooting Syslog Reporting Problems
Problems generating syslog reports can mean that one or both of the configuration settings for the syslog host or Message type is not correct, or that data is not reaching the syslog host. If you have problems displaying syslog report information, or you receive a "Database Empty" error message, check the following items:
•Review the section "Generating and Printing Syslog Reports" for configuration requirements. Configure the SYSLOG Host and Message Types settings.
•Verify that messages are occurring at the PIX Firewall. From the Management Client, click the Alarm and Report tab. Under the heading, Immediate SYSLOG Message, click ON to display a syslog message window that reports messages as they are received at the syslog host. If no messages appear in the SYSLOG Message Window, it might indicate that no syslog messages are being generated by the PIX Firewall. This can be normal if no activity is occurring at the PIX Firewall. To generate a syslog message, use Telnet to log in to a PIX Firewall that has been configured with the IP address of the syslog host running this PIX Firewall Manager. If configured properly, a message should appear in the SYSLOG Message Window indicating that the connection was permitted.
Note Close the SYSLOG Message Window after you have verified that information is being received at the syslog host. These messages can fill up system memory on the host, slowing performance.
•Verify that the Message Type is set to capture level 7 messages. The PIX Firewall Manager requires you set the Message Type to level 7 before generating reports. From the Management Client, click the Administration tab and select Administration>SYSLOG from the Main Tree. Click Edit to display the Edit SYSLOG Output dialog box, and change the Message Types level if necessary.
Note The Facility setting in the Edit SYSLOG Output dialog box is not used by the PIX Firewall Manager Management Client for generating reports. The report wizard provided with the Management Client references hosts by IP address.
If syslog reports display both host names and IP addresses, verify that the Windows NT system running the Management Server is able to resolve host names. The PIX Firewall Manager attempts to resolve IP addresses with host names when the Management Server receives syslog messages. If it finds a host name for an IP address, the address and host name pair is stored in a database on the Management Server. This database is used to create SYSLOG reports. If the Management Server is unable to resolve the IP address with a host name within 15 seconds, only the IP address is logged in the database. As a result, SYSLOG reports might include both host names and IP addresses.
Limitations and Restrictions
1 PIX Firewall Manager cannot be installed or uninstalled under Windows NT domain administration logins. If you attempt to install PIX Firewall Manager on this type of login, the following message appears:
You are not authorized to run this installer.
2 When installing the PIX Firewall Manager on a backup domain controller, be sure that the backup domain controller has connectivity with the primary domain controller. If connectivity is lost between the backup domain controller and the primary domain controller, the following message appears:
Could not find the domain controller for the domain.
In this case, the installation procedure cannot add the PIX Firewall Manager users and groups to the Windows NT Security Account Manager database, and attempts to use the PIX Firewall Manager will fail.
3 PIX Firewall Manager does not support the following PIX Firewall commands. To view, add, or change these configuration features, use the PIX Firewall's console port or start a Telnet session to access the PIX Firewall.
•aaa authentication enable|serial|telnet console tacacs+|radius —aaa authentication enable console requires authentication to access the PIX Firewall console and lets you log changes made to the PIX configuration from a serial console session.
•clear logging disabled—lets you enable all previously disabled system messages.
•clock set —lets you set the PIX Firewall's clock that is used in conjunction with logging timestamp to timestamp syslog messages that will be received by the syslog server.
•config net—read the configuration from the TFTP server.
•hostname—change the PIX Firewall host name.
•name or names—permit users to map hostnames to IP addresses, thus allowing users to specify host names in the places where IP addresses are permitted.
•ping—determine if other IP addresses are visible from the PIX Firewall.
•sysopt—tune advanced PIX Firewall TCP cut through proxy features and enable or disable the PIX Firewall IP Frag Guard feature.
Note The established command in the command line interface is same as the multimedia feature in the Management Client. To use this feature, select Administrator>Administration>Multimedia.
4 The following configuration features can be viewed on the Management Client but must be added or changed at the PIX Firewall's console port or Telnet session:
•MTU size. You only need to change this if you have a Token-Ring interface. Use the mtu command.
• Interface configuration. Use the interface, nameif, and ip address commands to change the values if needed.
•Failover. Use the failover command if needed.
•Private Link. Use the link and linkpath commands.
5 ICMP protocol services, such as ping, are initially blocked in both directions by the PIX Firewall and require a conduit configuration. To configure a conduit, select Inbound>Static>Conduit.
If a help topic is not available, information on the topic can be found in the Configuration Guide for the PIX Firewall Version 4.3. Also view the Release Notes for the PIX Firewall Version 4.3.
Important Notes
1 When a Management Client is running, only the following configuration changes to the PIX Firewall units made through the console or Telnet sessions are reflected in the client applet: conduit, static, global, nat, outbound, apply, and alias. To view the updated configuration for any other PIX commands modified via the console or Telnet sessions, click a PIX Firewall folder, then click the Reload Configuration button.
2 If a client is already connected to a Management Server and a second client on the same machine tries to connect to the same Management Server, then the first client will be disconnected and the second client will be connected.
3 All members in the PIX Admins group have read and write access, and all members in the PIX Users group have only read access; do not change the PIX Firewall configurations. Usernames that do not belong to one of these two groups cannot use the Management Client applet.
4 When accessing the Management Server from the Management Client, do not use the loopback address (127.0.0.1) in the URL. Using the loopback address causes an "I/O Exception" error on all online help and description pages. Refer to "Starting the Management Client" for more information on using the Management Client.
5 If you change the PIX Firewall enable password in Administrator>Administration>Password, wait for confirmation of password change prior to entering additional commands. If you enter an invalid password, confirmation of the change can take several minutes while the server tries to validate the entry. In the case of an invalid password, additional commands can appear to hang until the server returns confirmation that the change was unsuccessful.
6 Initially, no syslog setting information displays in the Admininstration>SYSLOG panel. Press the Refresh button to display the current information. Syslog information in the daily syslog file is now saved every 10 minutes by default. You can change the time interval for saving syslog information by setting the value in the SYSLOG Notification Settings tab.
7 You can specify that syslog messages be marked with the current time. To configure each PIX Firewall unit with the timestamp option, select Admininstrator>SYSLOG, set the logging type to Timestamp and set the status to Enable.
Note You must set the date and time from the PIX Firewall command line interface using the clock set command before timestamp information will appear in syslog messages. You cannot set the date and time from the PFM Management Client.
If you have problems installing or using the PIX Firewall Manager, check the following items:
•Installing the PIX Firewall Manager generates the following error message:
A version of the PIX Firewall SYSLOG SERVER is detected on this machine. You must
uninstall PIX Firewall SYSLOG SERVER before installing the PIX Firewall Manager.
If the PIX Firewall Manager installation detects the presence of the PIX Firewall Syslog Server application on the same system, it displays a message warning you that both applications exist. The PIX Firewall does not support running both the PFM and PFSS applications at the same time. You must use either PFM or PFSS, but not both. For more information on installing PFSS, refer to the Quick Installation Guide for the PIX Firewall Version 4.3.
•The PIX Firewall Manager reports that it cannot connect with the PIX Firewall unit.
Verify that the PIX Firewall has been configured for Telnet access from the Windows NT computer where the PIX Firewall Manager Server is installed.
•The PIX Firewall Manager denies user login access.
Verify that the user is a member of the PIX Admins or PIX Users groups on the Windows NT computer. If the user is not a member of a group, add the user.
•The PIX Firewall Manager installs but does not run.
This can indicate that the client portion of the application is not communicating with the server portion. To determine where errors might be occurring, use the following procedure to launch the PIX Firewall Manager to the desktop:
Step 1 Select Start>Settings>Control Panel>Services on the Windows NT computer.
Step 2 Scroll through the services to locate the PIX Firewall Manager Server.
Step 3 Double-click PIX Firewall Manager Server, which displays the Service dialog box.
Step 4 In the Service dialog box, check Allow Service to Interact with Desktop and click OK.
Step 5 In the Services dialog box, click Stop to halt the PIX Firewall Manager Server; then click Start to restart the service.
Step 6 Start the PIX Firewall Manager. Errors generated by the application appear in the PIX Management dialog box.
Copy the errors messages in the dialog boxes and use Cisco Connection Online (CCO) for additional support.
•The Management Client stops running and reports Java applet errors in the status bar.
If the Management Client appears to stop working and reports Java applet errors, use the following procedure to launch the Java console from the web browser.
•From Netscape Navigator, select Communicator>Java Console from the browser menu.
•From Internet Explorer, select View>Internet Options>Advanced and select Java Console from the menu options.
The error messages appear in the Java console panel. If the error messages report security violations, it can mean that the Management Client is having trouble communicating with the Management Server. In such cases, try the following:
•Close the Management Client and enter the client location in the browser again using the HTTP protocol as shown here:
Do not use File>Open from the browser menu to access the Management Client.
•Verify that you have not changed the IP address of the Windows NT workstation running the Management Client. Changing this address can generate security violation messages. If you change the IP address of the Windows NT workstation, you must edit the IP address of the Management Client in the following file on your local disk:
\Program Files\Cisco\PIX Firewall\jclient\netscape\firewall
If the problems persist, use Cisco Connection Online (CCO) for additional support.
