[SOLVED] PXE/netboot: login failed

[shade]

Hello,

We are trying to install a computer with the win10 netboot product, and it fails with a similar failure as in this thread:

viewtopic.php?f=7&t=10928&p=47612&hilit ... dom#p47612

After the PXE boots, we choose the name the computer shall be named, and the try to login with the adminuser, and gets this error:

"Login failed: getrandom() initialization failed. (_ssl.c:726)"

The error comes no mater what we write as login, seems that there is no connection to service.

The server is a Ubuntu 18.04.2 LTS running inside a VMware 6.5.

Hi

could you please ssh onto the machine
username: root, password: linux123
and run the following command:

Code: Alles auswählen

/usr/sbin/rngd -b -r /dev/urandom -o /dev/random

and then

Code: Alles auswählen

master.py

and see if this resolves your problem

are you running in UEFI or BIOS mode?

Cheers
Mathias

Hello,

Just FYI it is our own installed Ubuntu server, not your vmimage.

I ssh onto the server and installed rngd (apt install rng-tools) as is what missing, then ran:

Code: Alles auswählen

/usr/sbin/rngd -b -r /dev/urandom -o /dev/random

master.py is not to be found on our server

We are running in BIOS mode.

After running rngd I rebooted the server, and the rebooted the computer (client) to launch the bootimage also.

It ran once after the command, but now it is back to same error

Hi

I was a bit unclear on where to run the rngd command
It is supposed to run on the client, what bootet into the bootimage.

Cheers

Hi,

Okay, that explains alot. Will try on the client, is there a fix on the way to the bootimage?

Regards.

[m.radtke]

Hi

yes there is an experimental version of the bootimage. it runs the rngd command twice with a little pause. Hope it helps. We had this issue when the bootimage was in internal testing but with the rngd command run once we didn't have it since then

[shade]

I will try and install the updated bootimage.

[m.radtke]

wait. there is still an error inside

I will upload another version soon.
Cheers

[m.radtke]

Hi

there's a new bootimage in opsi 4,.1 experimental (https://build.opensuse.org/package/show ... -bootimage).

This version starts the RNG command twice with a little break in between

Feedback is very welcome

Cheers

The new image seems to solve the problem

I will try some more tests to be sure, but the first computer is installing Windows 10 now so I think it works.
