Openwrt/etc/rc.button/reset Saving Configuration security scripts

Write a/etc/rc.button/reset script to deal with the feedback of security, status and configuration change.

Remote operations Press the reset button and store the configuration, script file:

#!/bin/sh path= "$PATH:/usr/local/sbin/:/usr/local/bin/" # Only run on button release. [["${action}" = "released"]] | | Exit 0 # Logger "$BUTTON pressed for $SEEN seconds" # env >>/tmp/reset-button if [["$SEEN"-le 1]]; Then message= "RESET button:retain current overlay, restore safebackup, and reboot" echo "$MESSAGE" >/dev/cons OLE logger "$MESSAGE" safebackup restore && reboot & Elif [["$SEEN"-ge 3-a "$SEEN"-le 5]]; Then message= "RESET button:wipe overlay, restore safebackup, and reboot" echo "$MESSAGE" >/dev/console lo Gger "$MESSAGE" Safebackup fullrestore elif [["$SEEN"-ge 9-a "$SEEN"-le 12]]; Then message= "Reset Button:wipe overlay (factory reset) and reboot" echo "$MESSAGE" >/dev/console Logger "$MESSAGE" jffs2reset-y && reboot & Else message= "RESET button:error. Pressed for $SEEN seconds.
    Do nothing. " echo "$MESSAGE" >/dev/console logger "$MESSAGE" fi

Another secure backup script:

#!/bin/sh # This script is written to run under the BusyBox ash shell.

# # Save and restore a safe configuration backup state for the host.
Export bakdir= "/safebackups" Export savefile= "/safebackups/safebackup-$ (hostname)-$ (date +%y%m%d%h%m%s)-$$.tar.gz" Export restorefile=$ (find/safebackups/-maxdepth 1-mindepth 1-type f-name ' safebackup-*.tar.gz ' | head-n 1 2>/dev /null) Export sysupgrade_conf_tar= "/tmp/sysupgrade.tgz" pidfile= "/tmp/$ (basename $0.pid)" myname=$ (basename $) #--EC

    } f_validate_restore () {# Validate before a restoration.
    # If There is no restore file, there are nothing we can do. if! [-F "$RESTOREFILE"];
        Then Echoerr "Echoerr" error:no the restore file could be found. "
    Echoerr "" Exit 1 Fi} f_save () {# Save a backup. echo "# Make sure the Bakdir exists.

Before resetting the reset, a secure backup is performed, without a backup, and no reset is performed:
Button pressed for 0-1 seconds, save configuration and reboot, overlay no erase
Button pressed for 3-5 seconds, overly erased, storage configuration, reboot
Button pressed for 9-12 seconds, factory reset, overlay with erase, no Configuration Storage
