Hi Adam,

Perhaps set_ready has to be set to zero (with xmldbc -s) and then monitored until it changes back to one, to indicate that new realtime data has been populated?  Pure guess.  Like some sort of polling flag, though.  What other purpose might it have?  Set_ready was set to zero in Ian's database dump, yet it was set to one in yours. 

XGI sounds like a primitive server-side scripting engine.   It's a symlink to /sbin/atp.

With the file-system extracted with the firmware mod kit, [1] we can run strings against atp. That divulges a few other hard-coded references to xgi resources:

Code: [Select]

strings atp  | grep xgi
xgi_main
xgi_handlers
do_xgi
test.xgi
config.xgi
**.xgi
/config/doxgi/errermsg
ConfigSet(/config/doxgi/errermsg,Factory restore error ...)
ConfigSet(/config/doxgi/errermsg,Save and Reboot error ...)
reboot.xgi
restore.xgi
saveandreboot.xgi
downloadmessagelog.xgi
Summary_DSL_Wait.xgi
st_stat_wait.xgi

If strace was gotten onto the device, and attached to the xgi process, it should reveal the calls used to trigger the repopulation of the database with realtime data.  Bit of effort to get that working, though.

We can also grep the root file system from a desktop machine. Which shows that set_ready is referenced quite a lot from a number of static resources:

Code: [Select]

$ grep -r set_ready * 2>/dev/null
Binary file bin/alphaWanAgent matches
www/Wizard/Summary_DSL_Gat.htm:"<?ConfigGet(/runtime/dsl/set_ready)?>"
www/public/__menu.js: top.fPanel.location.href="st_stat_wait.xgi?&set/runtime/dsl/set_ready=1";
www/STATUS/st_stat_get.htm:"<?ConfigGet(/runtime/dsl/set_ready)?>"
www/js/Wizard/Summary_Screen.js: var url="Summary_DSL_Wait.xgi?&set/runtime/dsl/set_ready=1";
www/js/Wizard/Summary_Wireless.js: var url="Summary_DSL_Wait.xgi?&set/runtime/dsl/set_ready=1";
www/js/Wizard/Summary_3g.js: var url="Summary_DSL_Wait.xgi?&set/runtime/dsl/set_ready=1";
www/js/Wizard/Summary_Internet.js: var url="Summary_DSL_Wait.xgi?&set/runtime/dsl/set_ready=1";

www/js/STATUS/st_stat.js: var url="st_stat_wait.xgi?&set/runtime/dsl/set_ready=1";

Not immediately obvious how it works!  Could be interesting when you discover, though!

Thanks for the pointers on strace. You gave me some ideas and steered me in the right direction.
I got the web UI auto refreshing as it does, and then set ps in a loop to see what gets called...a bunch of stuff it turns out

Some of these, although they don't seem to do the updating magic.
