Hi guys,
I was wondering, as we are able to login to telnet, and access a bash line in the ZyXel VMG8324-B10A modem/router, and it has USB ports available for jffs, is it possible to install entware on it? My main goal is to install openvpn client/server on it.
Anybody with an advice?
Many thanks.

Confession : I had to google what entware was and read the package list (http://pkg.entware.net/binaries/armv7/Packages.html) with interest, wow theres a lot of options. I like how you can instal your own PBX exchange, lol
Given that BusyBox is already installed on the VMG8924 (I know this because I have used it (http://forum.kitz.co.uk/index.php/topic,17179.msg315270.html#msg315270)) does it that mean that it already has entware installed or can it run natively?

Hi Chunks.
As far as I know entware is not installed on this device. I have experience with tomatousb, shibby, dd-wrt so far. All these can install entware-ng, and then install any of the packages. Usually they have an installer like entware_install.sh or so. I haven't found anything like this on this device. However, it has already an /opt folder, I found some files like /etc/wrt54g* so I suppose :fingers: installing entware should be possible. I don't have time messing around with the router at the moment, but maybe this manual may be useful: https://github.com/Entware-ng/Entware-ng/wiki/Install-on-the-TomatoUSB (https://github.com/Entware-ng/Entware-ng/wiki/Install-on-the-TomatoUSB)
I was just wondering whether anybody tried this before me. Please let me know. ;)

Just an update, I realised that I will need for this the rc.unslung start or rc.unslung stop scripts at the USB mount and unmount steps.
I assume it should be something similar as here:
cat << EOF > /tmp/script_usbmount.tmp
if [ \$1 = "/tmp/mnt/MYPART" ]
then
ln -sf \$1 /tmp/opt
/opt/etc/init.d/rc.unslung start
fi
EOF
nvram set script_usbmount="`cat /tmp/script_usbmount.tmp`"
cat << EOF > /tmp/script_usbumount.tmp
if [ \$1 = "/tmp/mnt/MYPART" ]
then
/opt/etc/init.d/rc.unslung stop
fi
EOF
nvram set script_usbumount="`cat /tmp/script_usbumount.tmp`"
nvram commit
reboot

However, I am somehow stuck because I don't know where and whether this router has an already scripts that start after mounting an USB or not. I found some bits under /sbin/wwan-add.sh etc. which seem as they are the scripts triggered when one inserts a 3G dongle. But I was unsuccessful finding where these scripts are triggered.
Another thing is the /sbin/hotplug, but this has only binary code.
And again, there are already some scripts on the router, however I haven't found a location where they are triggered and how to do it:

Any help?

Hmm . . . How about performing a global recursive grep for each script name of interest to see if that helps to identify from whence the script is called? :-\
For example --
cd /
grep -R 'dumpsysinfo.sh' *
-
Thanks for the reply. The problem is that I don't know for which script I am looking for.
Let me explain: I know that there is a script that runs every time the devices is booted up (/etc/init.d/rcS). However, I am looking for a script that runs before every mounting of a USB drive, and also that runs after any USB device is being unmounted.
The question is that how to identify this script? And if there is no such a script, how to create one.

If it was a normal system, rather than a SOC, I would suggest that you consider writing a relevant udev rule.
Would you be able to pull a copy of the SOC file system to a standard Unix/Linux based system and then examine the files so downloaded for clues?
-
I had the same idea and this is the reason I am investigating whether it is possible at all.
I managed to get access to bash so I suppose it would be possible to pull the SOC from the device. For the beginning I found this resource: http://tjworld.net/wiki/Zyxel/VDSL_IAD (http://tjworld.net/wiki/Zyxel/VDSL_IAD)
And there were other guys before me, who were able to download the mtdblocks: https://forum.openwrt.org/viewtopic.php?id=46498 (https://forum.openwrt.org/viewtopic.php?id=46498)
But here my skills are hitting my limits. I would be grateful for any advice leading me to the right direction.

Unless there is a fellow Kitizen who is able to step in and help, it might be best for you to ask in the OpenWrt forum.
I don't possess a ZyXEL VMG8324 and, from your own explanation, you really require more than just a few general hints/suggestions.

Has anyone managed to get an Openvpn client to run on a Zyxel VMG8x24-B10A router in the past couple of years?
I have an Openwrt client running on a TP-Link ARCHER-C7 v2 quite nicely.
