Hi,
You can connect to your Pc2 by using putty in windows and ssh into the Pc2.
For editing try midnight commander (mc) from a terminal. Point it to the desired file and press F3 to view, F4 to edit.
If not already installed, do apt install mc as root.

Surely the 100k resistor in series with a led must be a typo?

Thanks @Igor,
yes the problem is with script.bin. When using h3disp a script.bin with current date/time is placed in /boot which results in blank page.
when I copy /boot/bin/orangepipcplus from Sep 2 2017, with 36568 bytes from the *not updated* opipcplus over it, then I have a correct image.
However there is another problems, independent of script.bin:
There is an empty /etc/resolv.conf so that no names are resolved on internet. I have to call dhclient by hand, which produces a valid resolv.conf
Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)

After a long time of happyness I got careless and did an apt-get upgrade on one of the OrangePiPcPlus, and I my
Eizo FlexScan S1921 Monitor does not sync anymore.
I need a Resolution of 1280*1024 at 60 Hz with a pll_video of 432 Mhz.
I tried to reselect -m33 on h3disp but this did not change anything.
Is h3disp even supported anymore? Have there been changes to the legacy kernel or the
way resolution is selected?

Hi sniffyjaay
i have several opipcplus working in a "lean desktop" mode. They run armbian 5.25 jessie with the legacy kernel. I have tried to cut back on the insane writing of cache and state data by firefox, have installed qpdfview, the complete libreoffice, xfce4-power-manager and lightdm instead of nodm.
They are always on and run reliably over ethernet or wlan connected by the user's mount to a samba server with the data.
As surfing station and Office PC they run reasonably fast, especially when you consider that you don't have to wait for endless windows starts and -updates. When a user is logged in but not active, the OpiPcPlus falls asleep after selected half hour, and stays ready consuming only a few mA until the button is pressed, then it is back within a second. I did not bother with cases, but mounted the pi's vertically with 5mm distance on a little wood plate fixed to the desk. This plate also holds the wifi antenna on its top. The natural airflow before and behind the board is easily sufficient for cooling with a simple Al heat-spreader.
Until now I failed to have them fall asleep when unused without user login, although I edited logind.conf.
I would like to achieve this not only to save the little energy, but also to save writing to the SD card and to stop burning an image into the monitor.

Hi devs,
you are complaining about support nightmare. Microsoft had it much worse, with all possible shitty hardware being introduced without drivers and users expecting it to be supported. Their anwer: "Certified for Windows Vista" with a nice icon to be printed on the sales page. Conditions for the hardware vendor to include the icon was defined by Microsoft.
No hardware vendor will read the complaints in your forum. Armbian on the other side has quite the reputation. Do the same, define conditions for boards to be "Certified for Armbian" and push the vendors your way.

Hi
I did not really understand your network setup. Maybe describe it?
Is this the "two interfaces on the same subnet problem?"
In this case see here:
https://forum.armbian.com/index.php?/topic/2907-opi-zero-incoming-ssh-cant-connect/&
or do you have some "cable modem" which could be bound to the MAC Address of the connected interface?
Difficult to see from here.

Hi,
you can install
sudo apt-get install ncduand then run
ncdu /this way you can see which files are the biggest, and after a few hours, which are growing.
Keep us informed.

Hi Bruno
Armbian seem to offer only "server" distros for the pi zero which means without GUI.
I do not have zero, but opi pc plus for which armbian "desktop" exists.
you might try:
# apt-get install lightdm
followed by:
# service lightdm start
But it would be easier if you get an opi for which a desktop armbian exists.

Hi Loanrn
If you have quite a benign, electrically undisturbed environment and short distances to your sensors you might get by with properly shielded and grounded cables to your sensors. For factory floor environments and such you might want to read the ISOFACE product brief from infineon, which deals with isolating your I/O to the microcontroller.

leftsubnet=192.168.0.1/24 rightsubnet=192.168.0.1/24I am not used to strongswan syntax, but if the left subnet is the same as the right one,
how do you expect routing to decide which packets have to go through the tunnel between
left and right?

This module could help: Max232Module

I think a directly connected RS-232 port expects voltages of +3..15V for a logic "0" and -3..15V for a logic "1".
Your opi outputs signals that use 0V for "0" and 3.3V for "1".

I think you need the desktop version, and the video player mpv can be controlled by the command line or via ssh.

Good afternoon,
I am using armbian 5.25 on orangepipcplus with legacy kernel.
when visiting google.com site with firefox, I will only see the "mobile" site with restricted functionality.
On the bottom of the screen there is a link "Google-Ansicht klassisch" which should bring me to the desktop version of google. But when pressing this a popup tries to come up but will not finish its presentation. Now this tab is blocked,
I never get to accept google terms and conditions and can not use google.
Do you see the same behaviour?
Is there any known remedy?
PS: Yes, I tried firefox "safe mode" - same thing!
Thanks, gnasch

you should be able to repair this: just look at a lot of louis rossmann videos on youtube ;-)

you might want to try h3consumption utility.

maybe verify autonegotiation, check if successful and at what speed?

hi buratino
you will find corresponding threads by entering "remote desktop fun" into the forums search field on top right.

Setting network priority for multiple network interfaces?
in Beginners
Posted
Please verify the configuration of the DHCP servers. The "intranet" one should offer the correct address range and subnet mask for "intranet" but it must "not" offer a default gateway. The home one should offer the correct default gateway for reaching the internet.
