Re: Serial console access

Well, I just checked and I found Rx at 3 and Tx at 4. Don't know why that didn't work out for you. Huh, that's interesting. It appears that the pinouts really do vary between board revisions! I have two B3:s, neither have TX/RX on 3 and 4. Here's a photo of the bottom side of a B3 board, rev PC1, 2...

Re: Serial console access

Re the 6 hole pinout : I've determined¹ that pin 1 is GND but I was unable to detect TX/RX on any of the remaining five pins. I also took a macro photo on the bottom side of the PCB and tried to visually follow the traces from the TX/RX on the edge connector to the 6 holes. Again AFACT, while the t...

Re: Serial console access

Do note that the B3 board actually has 3 different locations where you can create a serial connection. Next to the onboard battery there are ... 2: a row of holes that are meant for a 6-pin male header which is a real straight forward solder job. Oh, do you mean these? You wouldn't happen to know t...

Re: Serial console access via a Rasberry Pi?

What about connecting the serial console via a Raspberry Pi? Are they pin compatible? Can I just connect pin cables directly between GPIO14+15 on the rpi and the rx/tx solering points on the b3? https://www.raspberrypi.org/documentation/usage/gpio/ https://elinux.org/RPi_Serial_Connection The elinux...

Re: Debian 10 "Buster"

I've compiled a new version with the missing nftables modules. Let me know how it goes... It works! With the new kernel /etc/nftables.conf loaded without errors and my wifi and lan traffic is now masqueraded by nftables as they previously were with iptables. Thank you. For the record, heres how I m...

Re: Debian 10 "Buster"

update-alternatives --set iptables /usr/sbin/iptables-legacy Did the trick. I had the same experience. With iptables-legacy selected my old masquerade rules works fine. Before giving in to the legacy approach though, I made a feeble attempted to migrate to nftables. Unfortunately it appears that th...

Re: Debian 10 "Buster"

I'm quite happy to join the choir for praise of Mouette in this thread. I'm grateful for your awesome work on the b3 Debian port. Thank you! I had an almost flawless upgrade experience. I used the command apt full-upgrade rather than apt-get dist-upgrade . It was somewhat surprising that the old ker...

Serial console access

Today I once again found myself wanting serial console access to my b3. While the rescue boot usb image works fine, I imagine that it is a bit more convenient to just connect to the console via usb. Anyone know if the follwing converter could work, as an alternative to the one mentioned on the wiki¹...

Re: Debian 10 "Buster"

Those names you refer to are the so-called 'Predictable Network Interface Naming' names. That has actually been around for quite some time now, at least 5 years, and if it had applied to the B3 you would have already encountered that issue. ... As it stands, eth0 and eth1 are defined as such in the...

Re: Debian 10 "Buster"

I haven't tried yet, but hope to do so real soon now. I'm a bit hesitant because of the move away from legacy network interface names. If I understand the release notes correctly eth0 and eth1 will be replaced by some really weird looking names. root@b3:~# udevadm test-builtin net_id /sys/class/net/...

Re: B2: Debian removed jessie powerpc repos - what now?

Debian keeps archives of their old non-supported releases, even after they're removed from the regular repositories. You should be able to use the archives as sources for apt. https://www.debian.org/distrib/archive I'm sure you're already aware, but you should obviously not expose your bubba to the ...

Re: xxxmyownb3.com with letsencrypt

Good to hear that you solved the problem, Puma. The fact that Letsencrypt does not publish the ip-numbers of their validation hosts is a security feature. It makes man in the middle attacks of the validation process harder. If you want certificates for hosts that you really do not want to expose to ...

As you state myownb3.com is just a dynamic DNS provider. This allows you to focus entirely on the error message from certbot.

Re: B3 replacement

One thing we haven't mentioned in this thread, about exit strategies from the B3, is what sort of community there is around thealternative devices. A quick search showed that there is a small community around the Turris omnia at https://forum.turris.cz/about I mention this because the community here...
