  1. Armhf is tested and working on H3. Please let us know if you succeed in building arm64 x2goserver.
  2. Could be related related to hardware acceleration / xfce. Install LXDE instead of XFCE. Good luck.
  3. While zeroconf may be a quick workaround for simplistic peer-to-peer networking, what you call "crap" is just the proven simple but powerful way to design, implement and test networking scenarios from basic to very complex. Networking is all about control, not dumbing-down automaticities. Serial console is best bet. Just use 4-pin cable. Do not connect RED (power).
  4. Most likely not Missing network design does not improve with added complexities like DHCP or zeroconf-style automaticities. As @igor and @arox already mentioned, the most simple foolproof networking is based on static IPs defined in /etc/network/interfaces. Sooner or later any Armbian user will have to learn Linux basics anyway and basic networking is part of it. Keep it simple and enjoy the power of lean, clean solutions. As most "network problems" are encountered by users of Microsoft/Apple systems, I'd strongly recommend a Linux system to work with Armbian boards as well.
  5. Using g_ether module on OPI will give you an USB ethernet connection between CutterBox and OPI. Steps : 1. OPI : enable g_ether module, configure static IP for new interface usb0, uplink OPI via LAN to systems providing data files 2. Cutterbox : configure static IP for new interface usb0 3. Cutterbox : Write small script to fetch data files via network into target directory on Cutterbox Have fun !
  6. Host treats mass storage gadget as private disk. See
  7. 1. port forwarding on OPI not needed ( see above post by @martinayotte ) 2. Make sure OPI is defined with static IP in /etc/network/interfaces and use this IP to configure port forwarding on the router. 3. Restart router after configuration changes Good luck.
  8. Simplest and safest way is to use ssh-server on OPI and forward a router-port to OPI ssh-port. With ssh port-forwarding you can tunnel any services over secure ssh connection.
  10. Just keep it simple. If you don't like SDcards or HDDs you could also use fast USB3 nano flash drives. In case you'd rather use network storage, use NFS as per Good luck.
  11. @jean-philippe Sorry to hear it took you so long to find Armbian. You'll find an entirely different culture here than what you might be used to. Armbian is centered around working software, not marketing hype. While you still might be struggling with HW/SW bought 2 years ago as the seller's website is a sadly abandoned construction site ( with the notable exception of the excellent OpenElec ) Armbian turns useless OPI bricks into well-performing little jewels with predictable behaviour. I'm strictly speaking as a user and my contribution to the project is some forum help, tutorials and documenting successfully solved use cases. So why not download a current Armbian, spend some time in reading documentation and forum help ? You spent 2 years on '99% fully working stable' , why not invest some hours to experience a stable and tested solution ? Welcome to Armbian !
  12. Censorship is ALWAYS wrong. No matter how much you disagree with someone's opinion, the right to voice an opinion is crucial in any civilized discourse. In a weak and decadent world only "nice" people are tolerated, while the dedicated and ambitious ones who actually get things done and are ready to stand up for a cause are loathed.
  13. Working USB-UART adapter . Shipping takes 2-4 weeks from China, other sellers may be faster. Raspberry Pi shops offer similar items as well. Good luck with your project.
  14. There are lots of dongles and only a few of them have a chipset with useful drivers. You can either reinvent the wheel with untested HW/SW or just simply follow the instructions for setting up a dual-interface wlan dongle as per Please follow the steps under 'Troubleshooting'. A working dongle costs <$2 , some reading time and discipline to follow instructions. Good luck.
  15. Maybe might help ? Solution with second interface (AP) is based on dongle 8188EU (see mentioned link for specifics) . Please follow instructions precisely. Good luck.
  16. @piknew Could you please detail the use case you're trying to solve ? From what I get from a quick glance you're automating backup of NTFS directories.
  17. I do actually . And this does also recharge batteries while the board is off and restart the board when sufficient juice is available again ?
  18. Of course it is much simpler to solve another problem than the one at hand The proposed simple solution works with any board.
  19. I love to encourage people making experiments and sharing their results. Basic knowledge is gained by learning and working with the basics. Users tend to trip over automated and nondocumented functionalities. Spending time on getting familiar with Linux basics is needed anyway for Armbian users, the paradigm shift from Windows to Linux cannot be avoided by automating away the basics. The clone functionality is provided by dd The restore functionality can be provided by a reasonably managed backup/restore system allowing access to unaltered versioned images of filesystems. A versioned backups is made by rsync referencing an earlier backup, storage and runtime are minimized by using hardlinks. Need a file from three weeks ago ? Go fetch it from the archive. Need to restore a complete system ? Get it from the archive. The beauty of this approach ? It is proven and simple, has little dependencies on ressources ( any old or new, physical or virtual Linux system will do ).
  20. The power bank uses a buck converter to load the 3v7 batteries from 5v input and a boost converter to pump the 3v7 up to your needed 5v. The output of the converter may or may not let you estimate the remaining battery capacity. Measure the voltage of the battery and you are set. Charging stops when a target voltage 4v2 of the batteries is reached, discharging stops when a low point e.g. 3v2 is reached. I combine TWO simple powerbanks by hooking them together on the battery side. Now I can charge through one circuit and discharge through the other simultaneously. Solar panels via step-down converter or various 5v chargers replenish the power bank and the board draws power from the batteries. Tested. Works. I'm afraid it won't get any simpler than that. Measuring the battery voltage will tell you when to shut down the board.
  21. It would probably make more sense to configure the Lite with g_ether enabled and usb0 with static IP.
  22. 'Work smarter not harder' is definitely the way to go. Automating and optimizing transport and compression of block devices solves what ? Intelligent versioning/cloning of file systems has been standard proven Linux practice with rsync and ext3 filesystems for ages and btrfs hopefully continues that tradition. The proof of any backup is not backing up your data. Your surprises start when trying to RESTORE. Zillions are wasted on backup concepts for lack of actual experience in restoring.
  23. For battery-buffered operation ( charging from solar or AC-DC DC-DC chargers ) see Battery buffers could be stacked in series to prolong runtime without charging or run in parallel to allow hot swapping of power supplies for added robustness. Bingo. Use low voltage on battery side to let ATTINY trigger OPI shutdown via GPIO pin, let ATTINY cut power to OPI after sufficient delay and restart power when sufficient battery voltage is available again.
