  24 +Module: mod_nvram
  25 +Author: Brian Wotring (brian@shmoo.com)
  26 +
  27 +
  28 +
  29 +DESCRIPTION:
  30 +
  31 +The mod_nvram module reads the key=value pairs stored in nvram.  This
  32 +is primarily for Linksys routers, but could be modified to run on
  33 +other systems if necessary.  On the routers like the WRT54G, the
  34 +nvram settings hold sensitive information that needs to be monitored.
  35 +The format for the record structure is as follows:
  36 +
  37 +    name:value
  38 +
  39 +USE:
  40 +
  41 +To use this module, all  that is needed is to include it in the System
  42 +block of a scan configuration, e.g.:
  43 +
  44 +    <System>
  45 +    ...
  46 +    Include mod_nvram
  47 +    ...
  48 +    </System>
  49 +
  50 +
  51 +PARAMETERS:
  52 +
  53 +There are no parameters for this module.
  54 +
  55 +PLATFORMS:
  56 +
  57 +Currently, only for the Linksys WRT54G and WRT54GS devices.
