Auto Restore Script

As stated before I only know enough about Linux to make me dangerous and did not write this script. Original credit goes to frater.

Background:
Router = Asus RT-N66U
Firmware = Shibby 95 AIO build
External Storage = 2GB MicroSD card in onboard slot.

I am using the backup settings script by Austin Saint Aubin
Also using the Tutorial by ray123 Make syslog go to a disk or another computer

If your not worried about logging then the ray's script is not needed and the sleep line can be removed.

Also, I think 60 might be a little extreme of a sleep time, I will play around with it later to see exactly what is needed.

Working Code:
filename: 75-factdefault.autorun (placed in root dir of sd card)

Code:

#!/bin/sh
NAME=factdefault.sh
CUR_DIR="/mnt/DRIVENAME"
restflag="${CUR_DIR}/just_restored"
 
wl0_ssid=`nvram get wl0_ssid`
lan_ipaddr=`nvram get lan_ipaddr`
 
if [ ! -f "${restflag}" ] && [ "${lan_ipaddr}" = '192.168.1.1' ] && [ "${wl0_ssid}" = 'Tomato24' ] ; then
  sleep 60
  logger -s -t $NAME "Detected a firmware reset"
  lastbackup="`ls -1t /tmp/mnt/DRIVE/PATH/TO/lastbackup_*.sh | head -n1`"
  touch "${restflag}"
 
  if [ -z "${lastbackup}" ] ; then
    logger -s -t $NAME "Unable to find a backup, will restore some handpicked settings"
    nvram set "nvramvar=nvramsetting"
    nvram commit
  else
    logger -s -t $NAME "Restore settings using ${lastbackup}"
    ${lastbackup}
  fi
  logger -s -t $NAME "Reboot"
  reboot
else
  rm -f "${restflag}" 2>/dev/null
fi

At this point, I know it works when external storage is enabled or you use shibby's 95 AIO or higher, which has USB and SD function enabled by default.

<s>The problem I am having is no logging is recorded.</s> No longer a problem

for reference here is fraters script untouch that works flawlessly in DD-WRT

Code:

#!/bin/sh
NAME=factconfig
NAME="$0"
[ -h "${NAME}" ] && NAME="`readlink "${NAME}"`"
CUR_DIR="`dirname "${NAME}"`"
restflag="${CUR_DIR}/just_restored"
 
wl_ssid=`nvram get wl_ssid`
lan_ipaddr=`nvram get lan_ipaddr`
 
if [ ! -f "${restflag}" ] && [ "${lan_ipaddr}" = '192.168.1.1' ] && [ "${wl_ssid}" = 'dd-wrt' ] ; then
  optlog $NAME "Detected a firmware reset"
  lastbackup="`ls -1t /opt/var/backups/*.essential.sh | head -n1`"
  touch "${restflag}"
 
  if [ -z "${lastbackup}" ] ; then
    optlog $NAME "Unable to find a backup, will restore some handpicked settings"
    nvram set "nvramvar=nvramsetting"
 
    nvram commit
  else
    optlog $NAME "Restore settings using ${lastbackup}"
    ${lastbackup}
  fi
  optlog $NAME "Reboot"
  reboot
else
  rm -f "${restflag}" 2>/dev/null
fi

Does the syslog survive a reboot?

Ok,I have been through the logger man page, nothing helps. Am i asking such a stupid question that I should know the answer and am just overlooking it?

No the default is for the syslog to be on the ram disk with limited number of small files. You can get the router to broadcast to a remote logger by web gui, or there are ways to move the file to usb disk, see for example

http://tomatousb.org/tut:make-syslog-go-to-a-disk-or-another-computer

Did the tutorial, Now i was seeing that it created a separate log file for 1970-01-01-0100 but wasn't being populated. So i placed a "sleep 60" in the script and began moving it around until it gave enough time to log. will update first post.
