  1. Fixed it! Apperantly it's an xrdp bug... This solved my problems : Raspberry pi
  2. Ive been doing some digging and it seems that the xRDP service is failed after a reboot: sudo systemctl status xrdp.service ● xrdp.service - xrdp daemon Loaded: loaded (/lib/systemd/system/xrdp.service; enabled; vendor preset: enabled) Active: failed (Result: exit-code) since Thu 2020-01-02 19:13:28 CET; 44s ago Docs: man:xrdp(8) man:xrdp.ini(5) Process: 4517 ExecStart=/usr/sbin/xrdp $XRDP_OPTIONS (code=exited, status=1/FAILURE) Process: 4509 ExecStartPre=/bin/sh /usr/share/xrdp/socksetup (code=exited, status=0/SUCCESS) Jan 02 19:13:28 rock systemd[1]: Starting xrdp daemon... Jan 02 19:13:28 rock systemd[1]: xrdp.service: Control process exited, code=exited status=1 Jan 02 19:13:28 rock systemd[1]: xrdp.service: Failed with result 'exit-code'. Jan 02 19:13:28 rock systemd[1]: Failed to start xrdp daemon. Some googling around revealed that this could be a recent bug in xRDP, more people have been reporting the behavior in the past months: Got xrdp Starting xrdp yields the following output, even after stopping the service first: sudo systemctl start xrdp.service Job for xrdp.service failed because the control process exited with error code. See "systemctl status xrdp.service" and "journalctl -xe" for details. Journal to log has no info from xrdp, just some login fail from OpenVPN i need to fix.
  3. Edit: Nevermind the unknown state seems to be normal.... I think there is something wrong with my local host, it’s states as unknown: ip addr show 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000 link/ether 0e:24:d9:ea:96:09 brd ff:ff:ff:ff:ff:ff inet 192.168.2.150/24 brd 192.168.2.255 scope global noprefixroute eth0 valid_lft forever preferred_lft forever inet6 2001:980:cd62:1:cc7d:c076:afd7:4863/64 scope global temporary dynamic valid_lft 3723sec preferred_lft 3226sec inet6 2001:980:cd62:1:adbf:9afd:ce2e:f8bd/64 scope global dynamic mngtmpaddr noprefixroute valid_lft 3723sec preferred_lft 3226sec inet6 fe80::3935:53f9:bb77:cddc/64 scope link noprefixroute valid_lft forever preferred_lft forever 3: wlan0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000 link/ether 6c:21:a2:37:91:7e brd ff:ff:ff:ff:ff:ff Should that be a source of the problem ?
  4. Hi there, First of all, have a nice christmas. Especially you Igor, im still amazed by what armbian is. I'd like to ask a question regarding a problem i'm having. Last two days i've been setting up my rockpi 4 as a replacement server. I had everything configured correctly and working. I left the rock on over night and discovered this morning that i couldn' t connect over SSH and vnc/rdp anymore. Since i couldn't connect and the rock was headless i pulled the power an forced a reboot. After the reboot i could connect to ssh but not over rdp or vnc. My app jump desktop gives the following error: Could not create SSH tunnel. Please make sure tcp forwarding is enabled on the server. Details: Chanel open failure (connection failed). The weird thing is, i have not changed anything since the last time, it just doesn't work anymore now so i dont know where to look to solve the issue. I have the following settings: address: 127.0.0.1:3389 (port is forwared in the router and open in ufw) ssh tunnel: username@ip_address with private key (also tried username@local ip 192.168.2.150 with key. no effect) (ssh is working so the keys or the adresses should not be the problem, tried the exact same keys and both ip as local ip for ssh) My sshd_config file is in the attatchment. note that i have set allowtcp forwarding to 'yes' as was requested in the error log of jump desktop. I've also tried re-enabling rdp in armbian-config no effect I've also tried running vncserver mp effect I've hooked up the system to a monitor and it just normally boots to desktop as expected. Does anyone have some tips where i should start looking for this problem ? I have a hard time doing this since it happened without me interfering. Thank you in advance. sshd.txt
  5. Okay I do apologize on forehand. Ive tried the following: sudo apt-get update sudo apt-get upgrade sudo apt-get dist-upgrade sudo reboot sudo modprobe g_ether modbprobe: FATAL: Module Gether not found in directory /lib/modules/4.4.192-rockchip65 Sudo cat /etc/modules is an empty file (it does exist) sudo ifconfig usb0 up gives a no such device error Sudo ifconfig -a doesnt have a usb0 output Sudo lshw -C network only shows wireless and ethernet connection cat /etc/os-release version = 18.04.3 LTS Bionic Beaver I think thats all i can do ? Thanx for the help in advance, greatly appreciated!
  6. ah yes i figured that but it didnt work in the first try. Ill try to get a bit deeper into it then, i guess you did something or pulled some strings. Thank you for that!
  7. My ipad has an usbc port, if i plug in a female ethernet adapter i can connect that to a wifi cable from the rockpi thereby using eth0 rather than usb0
  8. As a result of your feedback i've decided to buy a usbc to ethernet adapter, that should do the trick
  9. As said, i understand your case. I see you do your best and I thank you for that. All the best with the development of armbian.
  10. Hey of course I understand! I saw your YouTube video lecture on armbian. I understand this is more of a High-Tier user forum. That's why I also post my question at raxda. I've never complained on this forum, I just experience the other one as 'more kind', that's all, it's my opinion of experience. It was maybe not the kindest thing to say, but hey im not cursing or anything. I completely understand where you are coming from. I'm a teacher myself, I teach engineering at a uni (structural mainly, focused on offshore renewables and I also teach a bit of python programming (funny fact, I'm the python expert on my floor)), I have had my piece of 'dumb noob questions' :) You asked for an explanation, you got one, that's all. No hard feelings whatsoever. Now let's quit this 'feelings' nonsense and good luck on your crusade with armbian, I hope I can learn from you on the way, I already look forward being a more experienced linux person in a couple of years :)
  11. Hi there, Thanx for the reply In respond to my Radxa comment, I really love armbian, but on this forum i do sometimes get the feeling that i’m considered ‘dumb’ as a Linux hobbyist with no IT background. Hope you understand.
  12. I’ve tried the following link. this however didn’t work. first of all the file /etc/modules is empty whenever i reboot no usb0 interface will come online. Sudo ifconfig -a doesn’t show a usb0 interface Sudo lshw -C network only shows my wireless and ethernet connection. sudo ifdown usb0 && sudo ifup usb0 yields: ifdown: interface usb0 not configured Unknown interface usb0
  13. Hi there, I have a RockPi 4b running Arabian with Ubuntu bionic. I mainly use the board to contact it online over ssh/vnc/rdp to work in spyder and texmaker. Quite often the connection is slow however. Therefore I am thinking of changing the system such that i can just bring it on the road and connect it using a local network with the usbc cable outlet of the iPad and a USB port on the rockpi. The reason i would like to connect over a cable is speed and not having to use the WiFi so that both devices can still easily connect to a WiFi network for internet access. I have found many solutions where iPads are connected to raspberry pi’s. These solutions all have various forms, could anyone here please suggest me what the ‘ best’ solution would be in terms of ease of configuration and stability? What i’ ve found so far: - avahi - bonjour - connection related to nmap Are all these solutions even possible on a Arabian system ? And if the procedure is different, can anyone please help me het started ? Furthermore, if anyone of you is willing to help me think out the steps to configure the system that would be awesome (like really awesome). I’m only a Linux hobbyist so I’m still unable to find out the finesse between these programs. Thank you very much in advance. Johan
  14. I ended up just reinstalling the system
  15. To clarify, there only an emmc and not an sd card equipped. I've tried to physiclly reinstall the emmc but that did not solve the problem. When I try to mount the EMMC using an EMMC to SD converter the mounted card cannot be opened because it's read-only. Is this a sign of a failing emmc ?
  16. Hi there, I have a rockpi 4b running armbian bionic desktop legacy kernel 4.4y on a 128 GB emmc module, I’d like to use this machine as a server. I was just tinkering around with Plex, .bashrc and crontab while all of a sudden the keyboard mapping over RDP changed (e.g. > became ;, ~ became @ etc) (indication of the problem?). I tried to fix this by changing the system keyboard layout and running dpkg-reconfigure keyboard-configuration, this all didnt work. I decided to reboot the machine to see if that would work. After the reboot I could not connect to either RDP or SSH so I decided to connect the machine to a HDMI monitor. This resulted in the following output: Can anyone help me understand what I am seeing here and how this could have happened ? Is this even Ubuntu ? Or is this GRUB ? Where in the boot process is this ? My guess is that the whole EMMC is disconnected but this seems very weird since I did not touch the board in any way. (I have no SD installed) I’m now thinking of solving this problem by attaching the emmc to a sd reader and backing up the etc,home,opt,root,srv,usr and var folder, reflashing the image and putting the folders back. This is however a very destructive process so I hope something less destructive is possible. I also even don’t know if this is going to work since I have no idea how this problem was caused. Can anyone help me please ? Thanx in advance! Thank you in advance
  17. Sorry im an idiot and didnt want to post the solution... apparantly the HDMI cable did not reconize the output.
  18. So basically my best path would now be is to burn strech and update it manually to buster using something like: https://linuxconfig.org/how-to-upgrade-debian-9-stretch-to-debian-10-buster Or does this also update the bootloader ?
  19. For the record, i do know this already
  20. Thanx for the reply. So I can run buster when i use the old bootloader ? I do know the difference between update and upgrade, you just stated i should do an update, not an update and upgrade. How should i change the bootloader from the buster image without updateing the bootloader then ? Thank you.
  21. did that: image: Armbian_5.90_Rockpi-4b_Debian_stretch_default_4.4.182_desktop sudo apt-get update sudo reboot sudo armbian-config -> update bootloader successfull (went very fast ?) sodo reboot now it won't boot, no video, just the flashing of the red led twice. So i guess something is wrong with the bootloader ?
  22. Oops error i'm miximg up some versions... got a whole folder of armbian images.... Deleted that now and trying again.
