Installation Guide

- Introduction
  BigFix aims to solve the increasingly complex problem of keeping your critical systems updated, compatible, and free of security issues. It uses patented Fixlet technology to identify vulnerable computers in your enterprise. With just a few mouse-clicks you can remediate them across your entire network from a central console.
- BigFix Platform Unicode Support Overview
  BigFix Platform V9.5 gathers data from BigFix clients deployed with different code pages and languages, encode the data into UTF-8 format, and report it back to the BigFix server.
- Sample deployment scenarios
  The following deployment scenarios illustrate some basic configurations taken from actual case studies. Your organization might look similar to one of the examples below, depending on the size of your network, the various bandwidth restrictions between clusters and the number of relays and servers. The main constraint is not CPU power, but bandwidth.
- Requirements and assumptions
  BigFix runs efficiently using minimal server, network, and client resources.
- Types of installation
  Before you install the product, decide if you want to do an evaluation or production installation.
- Managing licenses
  You must obtain a license key before you can install and use BigFix.
- Before installing
  Before running the installation make sure that you read the following topics and run the requested activities if needed.
- Installing on Windows systems
  Now that you understand the terms and the administrative roles, you are ready to get authorized and install the programs.
- Installing on Linux systems
  After understanding the terms and the administrative roles, you are ready to actually get authorized and install the programs.
- Installing the clients
  Install the BigFix client on every computer in your network that you want to administer, including the computer that is running the console.
- BigFix Administration Tool
  The BigFix Administration Tool, also called BESAdmin, is the tool we use to perform configuration changes and maintenance operations.
- Post-installation configuration steps
  After having run the installation, make sure that you read the following topics and run the requested activities if needed.
- Managing relays
  Relays can significantly improve the performance of your installation.
- Introduction to Tiny Core Linux - BigFix Virtual Relay
  Follow the step-by-step sequence of operations needed to build the virtual machine, from the downloading of the ISO image to the complete setup and configuration of the BigFix Virtual Relay.
  - Architectural overview
    Tiny Core Linux (TCL) runs from a RAM copy created at boot time.
  - Phase 1 - Configuring the Tiny Core Linux virtual machine
    In Phase 1, you set up a virtual machine with the Tiny Core Linux operating system that can instantiate the BigFix relay.
  - Phase 2 - Preparing the BigFix Virtual Relay template
    After installing Tiny Core Linux on the virtual machine, shut down the virtual machine and edit the properties to connect the BESRelay-x.x.x.xx-tcl.i686.iso file.
  - Phase 3 - Configuring the BigFix Virtual Relay instance
    Depending on the choice you made when creating the template (manual deployment or auto-deployment), the method of deploying future virtual relay instances changes.
  - Maintenance
    After completing Phase 3, the Virtual Relay is fully operational and communicates with the BigFix core server.
  - Troubleshooting
  - Limitations
  - VMware and Open VM tools
    If during the template creation you specified "y" (yes) to the VMware Tools configuration, only a minimal set of Open VMware Tools was installed, because they are running on a Tiny Core Linux machine with a Text-based user interface only.
  - Auto-Deployment
    To instantiate the virtual relay instance by using the Auto-Deployment mode, you must copy the network.conf file into the /opt/bigFix/config directory of the instance that you are deploying.
  - Modifying the Virtual Relay template
    After you create the Virtual Relay template, you can deploy all the required Virtual Relay instances.
- Setting up a proxy connection
  If your enterprise uses a proxy to access the Internet, your BigFix environment can use that communication path to gather content from sites.
- Running backup and restore
  You can schedule periodic backups (typically nightly) of the BigFix server and database files, to reduce the risk of losing productivity or data when a problem occurs by restoring the latest backup.

Maintenance

After completing Phase 3, the Virtual Relay is fully operational and communicates with the BigFix core server.

Additional configuration, such as setting the maximum relay cache size or changing the relay advertised name, can be done directly from the BigFix Console, exactly like any other BigFix relay.

No in-band mechanism for remotely accessing the shell is provided by default.

Using a Fixlet, you can manage the following two types of upgrade:

Client and relay components: The client and relay components upgrade will be performed by using a specific Fixlet which allows the components upgrade within the BigFix infrastructure.
Tiny Core Linux platform: The Tiny Core Linux platform upgrade will be performed by using a specific Fixlet which allows the component upgrade within the BigFix infrastructure.

Changing the shell password

To change the shell password, log in using the existing password, then issue the following command:

You are prompted to enter the new password again.

To ensure the password persistence, insert the following three lines into the /opt/.filetool.lst file:

etc/passwd

etc/shadow

etc/group

and issue the following command:

Note: These steps are performed automatically if you deploy using the Auto-Deployment mode.

Rebooting the Virtual Relay

If you are within the shell and need to reboot the system, issue the following command:

Updating the Virtual Relay instance

After creating and deploying the virtual relay instance, you can still modify the deployed instance in terms of masthead installation or network configuration.

From the operating system command line, launch the script named bigFixLaunchMastHeadConfiguration to modify the BigFix server or relay IP address for the masthead installation.

From the operating system command line, launch the script named bigFixLaunchNetworkConfiguration to modify the current network parameters of the instance. For example, you can change an existing DHCP configuration into a network configuration that uses static IP parameters.

Time zone

After creating the template, you can still modify the current time zone set during the configuration by launching the script named bigFixTimeZone from the template shell command line as follows:

After setting the new time zone, run the following operating system command:
