Zyxel326 lost settings after reboot and other


Hello,

NAS Zyxel 326, don't know what version of linux is installed:
Linux storage 3.10.39 armv7l GNU/Linux

I have ssh access and after logon I see this message:
BusyBox v1.19.4 built-in shell (ash)

First I notice that, when I made some changes - crontab, edit config file, after nas reboots, changes are lost.
Is there any way to prevent this or somehow to put my settings at system startup?

For example I would like to use daily reports for my hdd smart status.
I make script to receive report and put in to crontab
Quote:
11 18 * * * /path/hddreport.sh && /bin/cat /path/`date +\%Y-\%m-\%d`-hdd.txt | /usr/sbin/msmtp -a mailjet my@email
I make registration in maiiljet for this purpose. Everything works fine.

From other side, when nas is rebooted it's remember settings - disk volumes, ip's, users and etc...
I found this file, where there is a lot of options setting up, during reboot, but it is Read-only file system.

Have you got any idea, where I can make changes, so after reboot, they will be kept and worked?

Thanks in advance !

Typically embedded systems like your NAS are not the same as a regular distribution. They are live systems that load from flash memory on the board and not from the hard drive. For that reason finding information is more difficult. You might ask the Zyxel on their forum or send an email to their support department.

Yes, I know that is not typical linux. I submit same question in zyxel forum, with no success.
I am trying to grep my ip from all files (~1TB information) and see in which file it will appear, but for now (2-3days) nothing.

The ifconfig or ip a commands will show the IP address. If using DHCP the client typically stores the lease in a file located at /var/lib/dhcp. There are a few ways to the parse the information from /proc/net if you want to go through the effort.

I would not expect any system information to be stored on the NAS hard drive(s).

In /var/lib/ I have only "samba". I know how to check and view my settings in console.
I am trying to do something else, will try to explain again.
May be when system is loading (startup, reboot) it reads configuration files from some rom, probably this "/ram_bin"
and I know that can't mount it and write it.

Anyway I made several settings on nas using web gui,which are remembered likes - ip addr, user account, information for raid, setting of service and etc etc.
So I am trying to find some system file, script, that reads this settings or during boot, make them active. If I found something similar I will put "my settings" there
and they will be loaded even after reboot.
