Re: Choose best 3G modem

I like this one best: Huawei E3372 http://consumer.huawei.com/uk/mobile-broadband/e3372/ runs with old fashioned AT-Interface (e.g. for ppp-daemon, wvdial, smstools) as well as with ncm-mode (Network Control Model for modem-manager).

You could always buy a plug type psu and simply take it apart you often find there are wires connecting the PCB to the plug part so you can simply un-solder them.
?

- it's cheap
- it's secure
- needs no plug socket
- it's tiny size

Re: iptables start before OpenVPN tunel is up?

Or, there should be some way to make the rules only AFTER the tunnel is ready. (That sort of implies a security risk though...) you can setup your rules anytime even when the referred interfaces do not yet exist. It appears that something in your configuration already sets up some iptables in a wro...

Re: Set the BCM2835_wdt to check if python script is running.

basically you just need to start writing to device file '/dev/watchdog' and continue writing within less than 15s (watchdog timeout is 15s). No configuration, no additional package needed.

that's what I do

I had to solve the same problem a few months ago with some of my amd64 based APs (APUs from pc-engines). After reading your question I tried the solution on my RPi APs - and it simply worked. Though there is no initramfs on the RPi. The mechanism to map the MACs seems to be little different here. I ...

The OP appears not to desire any form of login - hence my request for further info.
my solution just provides an instant root shell prompt at the serial console after reboot.

I.e. no user intervention at all is required for this to happen.

I hope that fully serves the OPs purposes :-)
