UCI when it is initializing the firewall rules when the system is booting up.
-10) Last, we need to copy the setup scripts in sentinel_setup/setup into /setup on
+10) We need to also create /root/sentinel_setup/register and copy the scripts in
+sentinel_setup/register/version_2 into it. These Shell scripts work with the
+Android app that registers and deletes devices to and fro the router.
+
+11) Last, we need to copy the setup scripts in sentinel_setup/setup into /setup on
our LEDE system. This contains a number of scripts.
- "startup.sh" will be run by the rc.local script when LEDE is booting up. This script
contains the initial firewall rules for Sentinel router and a number of workaround
- "show" shows the active iptables rules.
- "transfer" contains commands to transfer files through the "scp" command.
-12) Reboot the system and we will have a working LEDE router for Sentinel system.
