Hello! I run Armbian (just updated to version 21) from an 128GByte heavy duty SD card. I am just trying to setup searx (https://github.com/searx/searx) which is using Docker containers. One of the Docker containers won't start, throwing an error message: I searched for long, trying to find some possible solution for this issue. The most fitting seemd to be, where someone said: Yes, it's for another OS and hardware, but I found no other possible solution. So disabling apparmor through a kernel parameter, is what I am trying to achieve. I addded 'apparmor=0' to the bootenv, using armbian-config. I also updated the bootloader using armbian-config (is this necessary after updating env at all?). But: it does not work. dmesg shows the command line as: No 'apparmor=0' in there. And the initial problem with Docker remains. Can you help me please, I don't know how to go on from here .. Thanks! Edit: Btw, there was another issue which seemed to have resolved by itself, but maybe it's important: I did a dist-upgrade from 20 to 21 before. Then I rebooted and installed docker.io and docker-compose - but the docker-compose installation broke with an error, because zram/var/log was full at 49MByte used to 100%. I then uninstalled both, rebooted again, and then installed both packages again, which for some reason worked on the 2nd try ... but now I have noticed that zram/var/log is full most of the time (with no further errors so far..) Is this all right?

Hello! I found the reason: It simply is the default configuration in "/etc/ssh/ssh_config". There's the line " HashKnownHosts yes", which probably is supposed to make SSH a little more secure. I don't really see a problem with having the LAN's other hostnames available, and the hashing will prevent SSH hostname completion from working, as the hostnames have to be read from the ssh config files for this to work. So it would be nice, if armbian-config had an option to "Enable SSH remote hostname completion" with a note that this will lead to config files including clear readable hostnames (which in advance will set " HashKnownHosts no". Also the existing file ~/.ssh/known_hosts" has to be deleted for SSH to recreate it with non-hashed hostnames. Alternatively this behaviour can be overriden for the current user having a local configuration file "~/.ssh/config" with the contents: And the file permissions: 600

Hello! I have switched to zsh, but still I don't get more choice than before: "mediaserver" is the Armbian system itself. What I expect is to also have the other hosts in my network availaible, like "router, elite, prtsrv, ..." Like it is on my Manjaro-Notebook: I don't know how the names of my other hosts got into that completion list as I did not add them manually. I think they probably have gotten in there automatically by DNS, as they always are available. Een when adding a new host to my LAN it's directly available as an completion option. Thank you for all your help!

I have found a script here, but even this doesn't work, because "~/.ssh/config" doesn't exist on Armbian.

Thank you very much! I will make this running then!

Hello and thank you! By "it was working" you mean on the new releases with mainline Kernel? Or did you presuppose installing an legacy version of Armbian? I guess I'd be able to make it running if there's no essential incompatibility, I just would like to know if it's even worth trying or a waste of time.

Hello! I wish to make my OrangePi 'failsafe' in regards of spontaneous power losses and such, so I need to have it running write protected, with writes going to a special partition or just RAM. My searches yielded an 'ancient' way to freeze the root filesystem using overlayroot, which isn't supoprted anymore (https://docs.armbian.com/User-Guide_Advanced-Features/) As I think that this kind of 'headless embedded usage' is an usual scenario for SBC running Armbian and having seen there was a method for doing so before, I assume there probably is a popular modern method for doing so, but I couldn' find it. How would I do this with the current Bullseye release on my Prange Pi Plus 2E? Or am I suppsed to use the classic kernel? Thank you!

Hello! I have Ambian Bullseye running on an Orange Pi Pus 2E. On my Linux-Notebook with Manjaro I can easily complete hostnames using TAB. This does not work on Armbian. Is there a package I need to install? Or a configuration I need to change? Thank you!

This problem with Wifi-bridging in Linux is an ongoing mysterium: I have been experimenting with this for years, as I want the multiple KVM VMs on my notebook working in bridge mode, but I couldn't get it to run since I am using Manjaro, while it was working with Debian (but only for some of the USB-Wifi adapters I tried). The explanation why this wouldn't work seems plausible (Router MAC-address asignment, 4addr problem and yadda yadda yadda..), but: It worked with Debian, before, and also Wifi bridging always works in Windows. Searching the internet for this issue (Operation not supported), when trying to bridge the WiFi adapter to anything) yields a weird result of many people saying things like 'It's no problem' and the other lot saying 'It's not possible'.. and both groups seemingly haven't heard of each other, ever before So there isn't an discourse about that, although many people seem to be affected by this. As I also am suffering from this problem for years now, this situation ist really frustrating and painful, as I have to manually passthrough my notebook's WiFi adapter to one specified of the VMs everytime I need it, or alternatively use NAT, which both is uncomfortable and annoying, when you are working with all the time new VMs and changing network configurations. A tendence I noticed was, that it worked in Debain with some of my USB-WiFi adpaters, but never with an mini-PCIe-Adapter like in a notebook. I wished there finally was a solution for this, or at least a workaround.. I thought of something like creating an light LXC-container with Tinc or OpenVPN in it, and build a tunnel using the VPN through the WiFi from the router into the VM network, for having a fully working bridge to the LAN inside there.. but I have no real clue how this would be done in detail, as already (unprivileged) LXC containers are an big issue for me. My best tries ended, when I still needed to enter some static routes for making a VM behind the tunnel working, which defeats the purpose of using a bridge for 'ease of use'. xD
