7. Configuration

Here are a list of variables which should be defined in your configuration script (normally `~/.impostrc')

1. `MESSAGE_TRIGGER_SIZE'

   When Impost reads a message that exceeds `MESSAGE_TRIGGER_SIZE' in length - it will trigger a detection and cause Impost to analyze the buffer more intensely.

2. `ENABLE_LOGGING' and `LOGFILE'

   Logging is enabled when `ENABLE_LOGGING' is one; or disabled if zero. Log messages are written to the file set in `LOGFILE'.

3. `MAX_READ_SIZE'

   This controls how much memory is allocated for the buffer which will contain incoming messages. If a message exceeds this value, it will be read as a second buffer.

4. `CAPTURE_DIRECTORY'

   This is the directory where Impost will create a log-file containing the message history if a detection is triggered.

5. `SHELLCODE_DEFINITIONS'

   Location of the shellcode definitions file. You need to enter the exact filename - this is a required file.
