29.    System Maintenance

Right clicking on a connected unit in the TR Tree will open a menu allowing you to view important information about the unit, as well to perform authorized system functions.
 
                            System Maintenance options are only available when logged
                                         in to Remote Manager with an Administrator account.
 
 
    29.1.    System Maintenance Options
 
        29.1.1.    System Information

The System Information screen displays useful system information:

·          Software Revision – The current software revision on the Total Recall unit.

·          Analog Channels – The number of analog channels currently installed on the Total Recall unit.

·          VoIP & ISDN Channels – This is not relevant to your Total Recall Desktop or Rack unit.

·          Recorder ID – The currently assigned Recorder ID.

·          Stored Calls – The number of individual calls currently on the call database.

·          Disk Space Used – The percentage of Total Recalls onboard storage that is currently used.

·          Archive Device – The current default archive device.

                        None of this information is user editable.
 
        29.1.2.    Archive

‘Archiving’ copies call files from the onboard system storage to another storage media, such as DVD/CD or (optionally on TR Rack) to a network location, for greater portability or long-term storage.

Calls may be archived according to certain parameters. These parameters are:

·          All Calls – Every call on the internal database.

·          Found Calls – The calls found in the most recent database search.

·          Unarchived Calls – Calls that have not yet been archived to a location other than Total Recall’s onboard storage.

·          Tagged – Calls that have been manually ‘tagged’ by users.
 
  Please note that manually archived calls will not be
               included in any scheduled Automatic Archives.

                     To archive calls:

1.         Select Archive Calls by right clicking on a current
     Total Recall unit in the left hand menu.

2.         Select which calls to archive via the drop down menu.
     Choose to archive All Calls, Found Calls, Unarchived
     Calls or Tagged Calls.

3.         Choose which location you would like to archive to.
     Select from DVD/CD media or Network Location
     (optional on TR Rack, if configured).

4.         Select OK.
 

        29.1.3.    Rebuild TR Database

This option allows you to rebuild the call database on your Total Recall unit. A database rebuild is recommended where the system has been subjected to an improper shutdown.
 
                                  Please note that recording will stop while
                                          the system is rebuilding the database.
 
 
        29.1.4.    Update TR Software

This option allows you to install an updated version of Total Recall software on your system. You need a Total Recall Application CD to upgrade the software on the system.

                     To upgrade your Total Recall Software:

1.       Insert the Total Recall Application CD in the CD/DVD drive on the PC which runs Remote Manager.

2.       Select Upgrade TR Software via right clicking on a current Total Recall unit in the left hand menu.

3.       Select the Total Recall Application package (.tgz format) on the application CD as shown on the following screen capture:

4.       Click on the Open button, then follow the screen prompts to complete the upgrade.

Note that the Total Recall system will automatically reboot itself during the upgrade process. Recording does not continue during the upgrade process and while the system is rebooting, which may take up to 5 minutes to complete.
 
                         The upgrade function only affects application and operating
                                      system files. However as an extra precaution, it is recommended
                                      that you back up all important calls from the call database before
                                      you perform an upgrade.
 
                          Your passwords and system settings are not affected
                                       by updating the system software.
 
 
        29.1.5.    Load TR Settings

This option allows you to restore the Total Recall system configuration from a file that is stored on the hard drive of your Remote Manager PC.

                     To load TR Settings from a saved configuration file

1.       Select Load TR Settings by right clicking the Total Recall
 unit in the Device Tree.

2.       Navigate to a previously saved configuration file on your hard
 drive. Click on the file, and then click Open.

3.       Follow the on-screen prompts to load the new settings.
 

        29.1.6.    Save TR Settings

This option allows you to backup the current system configuration to a file that can be stored on your PC hard drive. This saved configuration can be used to restore your system to a previous configuration if required.

                     To save TR Settings in a configuration file

1.       Select Save TR Settings by right clicking the Total Recall
 unit in the Device Tree.

2.       Navigate to the folder on your hard drive where you would like to save the configuration file. Define a name for your saved configuration, then click Save.
 

        29.1.7.    Shutdown

This option allows you to remotely shutdown the system.
 
                          Note that the system will power off and recording will
                                 not continue until you restore power to the system.
 
 
30.    Event Log Tab

Use the Event Log tab to view a record of system events for the selected recorder.

      
 
    30.1.    Event Types

The Event Log may contain 3 types of event:

    Information

Information events are standard system events and do not require any further action.

  Warnings

Warnings are events that may indicate possible future problems, and should be
investigated – for example, failed database searches and power failures.

   Errors

Errors are events that must be investigated immediately, such as database rebuild failures, auto-archive failures, and DSP card issues.
 
 
    30.2.    Using the Event Log

To filter the displayed entries in the Event Log, click the button for the event type that you wish to view.

To refresh the Event Log, click .

The Event Log can hold approximately 100,000 entries. When the Event Log is full, new entries automatically overwrite old entries.

The contents of the Event Log can be selected and copied out into a text editor to allow keyword searches.
 
 
31.    Connecting Through Firewalls

Due to the virtually infinite number of possible network configurations it is impossible to document installation solutions for all eventualities.

However, the examples below should provide an idea of the principles behind configuring a Total Recall recorder for remote access via a firewall.

The main points to bear in mind are:

·          The recorder must be assigned a hostname using Remote Manager
 via a direct connection before it can be accessed via a firewall.

·          Port forwarding must be done at the firewall to allow audio data through.
 

    31.1.    Example 1: Internal Recorder, External PC

In the following example, the Total Recall recorder is installed on an internal network with an IP address range of 192.168.3.0/24.

The recorder has been assigned the address 192.168.3.109 to the LAN 1 Ethernet Port.

There is a firewall in place to provide secure access between the internal network and the internet.

The firewall’s public (WAN) address is 203.10.10.10, and the internal (LAN) address is 192.168.3.252.

PCs on the internal network are able to access the recorder directly via its IP address across the LAN.

A client would like to be able to connect to the recorder over the internet and through the firewall from home.

 
                         Figure 8 - Remote access - Total Recall behind firewall

     To configure the above example network to allow remote
      access through the firewall:

1.       On the Total Recall recorder, open Network Settings and
set the Default Gateway for the LAN 1 Ethernet Port to the
firewall’s internal address (192.168.3.252).

2.       Install Remote Manager on an internal network PC.

3.       Add the Total Recall recorder to the Remote Manager settings.

4.       Use Remote Manager to assign a host name to the recorder, for example totalrecall1.

5.       On the firewall, forward ports 10010 and 10011 to the recorder’s IP address (192.168.3.109), and port forward FTP (port 21) if you want to email calls or save calls to local folders.
  The above assumes that the IP Address and
               Base Port in the Remote Manager settings have
               been set 192.168.3.109 and 10010.

6.       Configure the external PC to resolve the hostname
 totalrecall1 to the firewall’s public IP address
 (203.10.10.10).
 
You can do this by editing the hosts file. For example, on Windows 2000 or XP, open the file: c:\windows\system32\drivers\etc\hosts, and add the following line:
 
203.10.10.10    totalrecall1
 
To verify that the hostname is being resolved properly, try pinging the recorder.

7.       Install Remote Manager on the external PC.

8.   Add the Total Recall recorder to the Remote Manager,
using the hostname instead of the IP address.
 
The internal recorder should now be visible from
the external PC.
 

       
    31.2.    Example 2: External Recorder, Internal PC

In the following example, the situation is reversed - the Remote Manager client PC is on an internal IP address, trying to access a Total Recall recorder which is external to the LAN.
 
              
                        Figure 9 - Remote access - Remote Manager behind a firewall

     To configure the above example network to allow
      remote access through the firewall:
     
        This process assumes you have already assigned a
                     hostname to the recorder. See Example 1.

1.        On the firewall, port forward UDP from ports 10001 and
10002 to the IP address of the PC running Remote
Manager (192.168.0.1).

2.    Install Remote Manager on the PC.

3.    Add the Total Recall recorder to the Remote Manager
 settings using the hostname instead of the IP address.

4.        Check the Manager Firewall check box, and enter the
external IP address of the firewall (203.217.22.165)
in the associated field.

                                    The external recorder should now be visible from
                                    the internal PC.
 
    31.3.    Example 3: Multiple Remote Manager Clients
               Behind a Firewall

The following example is similar to the previous one, but with two Remote Manager clients PCs behind a firewall, trying to access a Total Recall recorder which is external to the LAN.
 
 
                     Figure 10 - Remote access - Total Recall behind a firewall,
                                                      2 Remote Manager PCs

     To configure the above example network to allow remote access through the firewall:

1.       Configure the first PC as in the above example:
 
On the firewall, port forward UDP from ports 10001 and 10002 to the IP address of the PC running Remote Manager (192.168.0.1).

2.       Install Remote Manager, add the recorder (using the hostname instead of the IP address) with Manager Firewall checked, and the firewall’s external IP address supplied.

3.   Install and configure Remote Manager on the second PC identically to the first, but assign port 10005 as its base port (File menu > Advanced).

4.       On the firewall, port forward UDP from ports 10005 and 10006 to the IP address of the second PC (192.168.0.2).
 
The external recorder should now be visible from both internal PCs.

5.       Repeat the process for any further PCs, using different port
pairs each time.
 

    31.4.    Limitations of Firewalled Connections
 
        31.4.1.    Transfer of Files

Transfer of files is done using the FTP protocol, on its default port (21). If two recorders are behind the same firewall, it is not possible to port forward FTP to both machines. The user will only be able to transfer files from the recorder which is receiving FTP.

If this limitation is unacceptable, alternatives are using a VPN, or screen-sharing technology (such as Microsoft’s Remote Desktop Connection).
