Installation Guide

Learn the system requirements, licensing and installation instructions, and how to configure and maintain BigFix .
- 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.
- 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.
  - Enabling client polling
    
    If an HTTP proxy exists between a parent relay and a client or child relay, or between the server and a child node, apply this workaround to bypass a limitation, that is caused by the proxy and that affects downstream communications.
  - Connecting the console to the server through a proxy
    
    If the BigFix console is installed on the same system as the BigFix server and if a proxy configuration is set in Internet Explorer, then ensure that, in that configuration, the Bypass proxy server for local addresses and the Exceptions settings are correctly specified.
  - Setting a proxy connection on the server
    
    When you install BigFix V9.5, you are asked if you want to set up communication with a proxy.
  - Setting up a proxy connection on a relay
    
    Complete the following steps to allow the relay to communicate with its parent components:
  - Setting up a proxy connection on a client
    
    To set the proxy connection on the client, complete the following steps:
  - Best practices to consider when defining a proxy connection
  - Troubleshooting proxy connection
    
    Common problems you might find with a proxy connection.

Error in getting site content.

This error is a symptom that something is interfering with the process of downloading external Fixlet sites, for example patches for Windows. You might notice that you do not gather the latest version of external content sites you are subscribed to, or that you do not gather at all from sites whose name is listed in the License overview dashboard. In this instance, the error


     Unable
to get site content (failed to pass sha1 hash value checks)

is listed in the


     BesRelay.log

file; this file is located in:

Windows operating systems: /var/log/BESRelay.log

The reason is often a firewall or a web proxy that is filtering the content exchanged between the BigFix server and the sync.bigfix.com server.

To fix the problem, ask the system administrator to allow downloading traffic for the BES Gather service on port 80. If the problem persists, complete a traffic packet analysis to find the problem. An useful tool to perform a full network protocol analysis is Wireshark .
