Advanced User Settings

Advanced capture settings require changing the configuration file directly as follows. As many of these options are customizations, please discuss with [email protected] any issues or side effects seen

/opt/fmadio/etc/time.lua

Validate Config file

After modifying time.lua configuration file, please confirm syntax is correct by running the following

fmadiolua /opt/fmadio/etc/time.lua

The correct output looks like the following

fmadio@fmadio100v2-228U:~$ fmadiolua /opt/fmadio/etc/time.lua

Disable Web Admin Permission

By default the Web user account has full permissions. There may be cases where Web access is for download and analyzing PCAP data only. Where configuration can be not modified.

To disable Web Admin mode SSH into the system and change the setting in

/opt/fmadio/etc/time.lua

In the ["Security"] section

["Security"] =
{
    ["HTTPAccess"] = "enabled",
    ["Auth"] = "BASIC",
    ["ConfigAccess"] = "full",
    ["GUIMode"] = "full",
    ["EnableWebDAV"] = false,
    ["RADIUS_Secret"] = "nil",
    ["RADIUS_Host"] = "nil",
    ["RADIUS_Protocol"] = "nil",
    ["RADIUS_Timeout"] = nil,
},

Change ConfigAccess setting to be "user"

["ConfigAccess"]   = "user",

The config file should be checked for syntax errors. Then restart the system. Once restarted the Web GUI no longer has Admin privileges'.
