Re: nfsroot - firewall configuration on the client

Eh, you have a writable NFS share to which basically any computer/device in your network can make changes to.

But you do are concerned about setting up a firewall on the client?

Re: Piserver DHCP Proxy - Clients do not boot reliably

would a Pi4 with the beta netboot work? Generally speaking: Pi 4 do work with Piserver, yes. Provided you flash the Pi 4's EEPROM with the beta network boot code and the right bootorder setting. Don't know whether or not it may currently be affected by the same issue, though. IF you already have Pi...

The permissions for /home/pi in the nfs export appear to be correct (uid:gid=1000 mode=755).
Also double check the parent directories (/home and /) have "x" permission for other users.

Re: Piserver DHCP Proxy - Clients do not boot reliably

I'm not follwing everything, but could it be that dnsmasq sends the wrong file (and not the Pi asks for the wrong file)?

Re: Piserver DHCP Proxy - Clients do not boot (UPDATE)

When I boot them up one by one and wait until the login screen appears before I power up the next Pi, it works. But this worked without the SD cards also. Suspect that if you wait 2 seconds between powering up the next Pi, it also works. I think it might be a bootcode bug, in which the Pi is snatch...

Re: PiServer and Arduino

That does seem to be an issue with how you are doing the install or what you have as it works when installed under Raspbian as the "pi" user. Well, Piserver is a multi-user system for classrooms. So the user that will eventually run the application will be "name-of-student-that-logged-in", rather t...

Judging by those messages, that install script is only written to install Arduino for just the current user (which happens to be root, when running the script through the Piserver chroot shell), instead of for all users on the system. Suggest you ask the Arduino guys why they do not offer scripts/in...

Can you tell OPSI to stop sending PXE boot options to Pi clients?

Think it seems to confuse the bootcode into thinking it should get its stuff there:

Doesn't sound like a Piserver specific issue to me. There are no Eclipse packages for Debian Buster. (Not for Intel computers either) Avoid Eclipse if you can.

Re: RPI and Buildroot - QT APP on startup and Starting Network

Do device management through udev and it will load the modules asynchronously for you (in the background and no need to modprobe anything manually).
Do may need to comment out "udevadm settle" in the init script so it does not wait before continuing.
