Re: Outdoorbetrieb der Raspberry PI

Fang statt den ESP8266 gleich mit den ESP32 an. Die haben noch zusätzlich besonders gute Powersave-Features. Ich habe damit einen Sensor realisiert, der alle 5 Minuten aufwacht, Messwerte verschickt und dabei mit einer 18650-Zelle (~2000mAh) etwa 1 Jahr auskommt. Kostentechnisch unterscheiden die si...

Re: Does the Pi support booting from GPT drives?

It's not a big problem. The standard EFI / EFI System Partition stuff is way to complicated and cluttered for the Raspberry Pi. Pi's need their FAT32 boot partition to load the Linux kernel and after that everything is fine. Using Hybrid MBR/GPT , the ROM/GPU bootloader can fetch the kernel and conf...

[Zero W] Minimal current draw/boot times

Hi, I'm building a Raspberry Pi Zero W based off-grid WiFi camera setup. This camera will take a picture every 5 minutes with a RPi camera and send it over WiFi. Power is controlled by an external ATtiny85 and the Raspberry Pi only needs to signal when it's done with it's work. I've worked quite a l...

Re: No global IPv6

Deutsche Telekom is currently the only provider in germany which supports IPv6.
Are you using D1/T-Mobile ?

o2, Vodafone, E-Plus and so on do not work.

Works nicely with Safari on via D1-LTE:

Re: No global IPv6

OK. I don't see a reason why your Pi needs a firewall configuration at all, but that's another story.

Code: Select all

net.ipv6.conf.all.forwarding=0
net.ipv6.conf.all.accept_ra=2
net.ipv6.conf.all.eth0.accept_ra=2
net.ipv6.conf.all.default.accept_ra=2
Try putting this in your /etc/sysctl.conf. Reboot after that.

Re: No global IPv6

iptables and ip6tables are not services, you don't need to start them via systemctl.

If your script ran and configured the ip6tables properly it should work.
Have you rebooted in between?

Ah!
Make a copy of that script, remove all the ip6tables lines and reboot the Pi.
If it then works, we‘ll go from there ;)

Re: No global IPv6

Ah! Yes, there's the problem.
You have IPv6-firewall rules configured. They are probably blocking the autoconfiguration.

I suppose you have installed a VPN server on the Pi a while back? Do you remember where it's scripts are? Especially something that calls the ip6tables?

Could you post your:

Re: No global IPv6

You set it to 0? Have you rebooted since?

EDIT: These settings need to be in /etc/sysctl.conf to be permanent. That's also the place where you need to enable the accept_ra.
