Description: The mod_nvram module was developed specifically to monitor
|
|
configuration settings stored in nvram on Linksys devices.
|
|
In the future, this module could be used to monitor other
|
|
attributes of similar devices.

Version: 0.1

+Module: mod_nvram
|
|
+Author: Brian Wotring (brian@shmoo.com)
|
|
+
|
|
+
|
|
+
|
|
+DESCRIPTION:
|
|
+
|
|
+The mod_nvram module reads the key=value pairs stored in nvram. This
|
|
+is primarily for Linksys routers, but could be modified to run on
|
|
+other systems if necessary. On the routers like the WRT54G, the
|
|
+nvram settings hold sensitive information that needs to be monitored.
|
|
+The format for the record structure is as follows:
|
|
+
|
|
+ name:value
|
|
+
|
|
+USE:
|
|
+
|
|
+To use this module, all that is needed is to include it in the System
|
|
+block of a scan configuration, e.g.:
|
|
+
|
|
+ <System>
|
|
+ ...
|
|
+ Include mod_nvram
|
|
+ ...
|
|
+ </System>
|
|
+
|
|
+
|
|
+PARAMETERS:
|
|
+
|
|
+There are no parameters for this module.
|
|
+
|
|
+PLATFORMS:
|
|
+
|
|
+Currently, only for the Linksys WRT54G and WRT54GS devices.
