[Gentoo|Bubbagen] experimental nftables support added to bubba-overlay

As xtables support appears to be degrading for newer kernels (xtables-addons can already no longer be compiled on kernel versions higher than 4.14.nnn) the next release of Bubbagen will be exclusively using nftables backend for firewalling. As part of the preparation I have added a prerelease of the...

That doesn't sound good. You could check out the following external link for hints how to proceed:

Re: Bubba 2 crashed - how to recover files?

Unsure if the same partitioning method was used on the B2, but on the B3 the data partition is set up as an LVM to allow it to be configured with a mirror disk (RAID-1). If Qnap supports this method of soft-raid you could try `vgscan` if it can find the LVM and the volumes inside it.

Re: Excito Bubba 3 - compatible SSDs ?

I get that. I like to have the cable detachable as well, particularly because I have multiple units. The points indicated in the wiki are not suited for positioning headers though. There are however in fact three different places on the board where you can create a serial connection, apparently depe...

Re: Excito Bubba 3 - compatible SSDs ?

Hi Chris, What I found was that changing u-boot environment variables from userspace doesn't actually work. That is, at some point I did manage to get it to to do what I wanted but it looked ugly and I kind of expected the hack to start failing at some point. So I ended up doing what I didn't want t...

Re: Excito Bubba 3 - compatible SSDs ?

What you need to realize is that the u-boot used in the B3 is from 2010 (June 29). This means that any hardware requiring newer drivers will not be supported. According to Johannes the EVO 840 series was supported, but Sakaki- mentioned some four years back that she owned a Samsung SSD that was not ...

Re: Serial console access

Just verified and the board on the spare unit is in fact an RF1 2011. Did not re-run the beep test. I guess I may have suffered from an occupational hazard, starting the count from 0 instead of 1.

Re: Serial console access

Well, I just checked with a spare unit and I found Rx at 3 and Tx at 4. Don't know why that didn't work out for you.

Re: Serial console access

That's the one ;) Shamefully, no. I did in fact not register which pins represented what. There might be some old forum post where I do mention them though. As I happen to have multiple units I opted for the special connector which makes it plug-and-play for every board. But you can simply "beep" th...

Re: Serial console access

Pretty sure that the FTDI galvanically separates input and output. This makes pretty good sense and I'm assuming the CP2102 does the same. In fact if I remember correctly Excito themselves had some type of electronic buffering between the 9-pin RS232 plug and the front header on the B3 board (Johann...

Re: Debian 10 "Buster"

I just upgraded and it worked flawlessly. One thing I'm still tracking is why Shorewall doesn't see the iptables NAT modules any more, but I don't believe this to be a kernel problem. May like to check kernel config anyway. There have been some changes to Netfilter config names and whether or not t...

For other curious b3-fans, the kirkwood-b3 device tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/arm/boot/dts/kirkwood-b3.dts Yes. In case you should want to compile your own kernel, do note the 'gpio-led' section. The default state for these leds is in fact 'off...

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 devi...

Re: Booting b3 without battery or working CMOS clock

Must be something else. I have a box that I use for maintaining the Bubbagen OS and that hasn't had a good battery for years already. That box never fails to boot.

One other thing to note is that the led should be coloured purple during boot. Red indicates an error.

Re: How to boot a b3 in rescue mode with Debian

You probably used an unsupported USB stick. It's a bit tricky to say which ones are supported though, but it's all about the internal chip. As a rule of thumb it needs to be USB2 and its capacity should not exceed 8GB. Most chance of success appears to be with the cheapest possible USB sticks, often...
