FACT uses four types of configuration files that you must create before you can use the FACT software. These configuration files provide information about the network that you want FACT to analyze. You create these files after you install the FACT RPM (see Installing FACT Software) and before you use FACT. After familiarizing yourself with the fact configuration file types in About FACT Configuration Files, proceed to Creating FACT Configuration Files.
Note: FACT can operate with no configuration; however, the application is minimally useful in an unconfigured state.
