Revision 1253, 10.5 KB (checked in by benoitg, 6 years ago)

Node.php: Improve getCurrentRealNode()
Implement #4: Allow the user to easily come back to the portal by typing in the root auth server adress from a hotspot.
Log the system information sent with the gateway since almost forever: sys_uptime, sys_memfree, sys_load, wifidog_uptime
NodeStatus?.php: Include the above information
node_list.html: Include wifidog_uptime if the hotspot is up.
Menu.php: Sort menus alphabetically according to the user's locale. TODO: Implement menu weights.
NodeLists?: Only list node types that have dependencies met in the menu. Refactor the NodeLists? for proper object-orientation.
