Hi
congrats to your great 10 cores CPU. It was released in Q1 of 2022, so it is rather new. Maybe this is the reason you are unable to boot the Exam system. I guess it would be supported in some future RH RE ISO releases. Please try an older, more likely compatible computer.

Hello, 
 I've just downloaded rhrexboot.iso and burned on an USB drive , but when re-inserted it asks for a password...
Also, documentation shows the ISo file should have an MD5 checksum of 0dd72ac558fc1afbf0c0e1fa4b366f10 while my one has 478157b7675223468d83253a241a1fd5.
Any idea why ?  Thank you

Hi

The checksum is 478157b7675223468d83253a241a1fd5. The documentation needs to be updated. The password would be for the USB drive and not for the ISO. Could you help us with the screenshot of the prompt

It is a brand new usb key, used only for this dd, It was accessible before the dd operation.

Using CentOS Stream 8

The password is there because the ISO contains an encrypted filesystem (partitions) . Do not re-insert the USB stick after you create it to the same operating system. Just use it by booting from it. If you delete the partitions from the USB stick, the USB stick will became usable again

Hi,

The MD5 checksum  for the latest version is 478157b7675223468d83253a241a1fd5.Yes, ISo prompts for password when you try to open the file which is not required. You can plug in the USB and select the option "Boot using External USb drive" and boot using Live image.

Thank you , booting from USB seems to work (I will finish the job later).
What was directing me in the wrong way was the documentation (apart from the checksum, also the lsblk view after the dd operation should be corrected since the disk is password protected...)
Have a nice day

Hello All,

Looking into this thread and the issues people encounter with the remote exams ISO, I'm having second thoughts.

I tried the remote exam iso ( a couple of versions)  but it failed to discover my wifi adapter.

Modern laptops don't always have ethernet adapters , docking stations are not supported.

Also built in webcams are not allowed. Need to buy a webcam just for the exam.

Exam center not available in my region.

So what are my options?

  1. Go buy a new laptop and hope is supported + Webcam
  2. Buy a Desktop PC + Monitor + Webcam and hope for the best.
  3. Get a Flight to a country with exam center 

I 'm very frustrated. 

Maybe it's time for Red Hat to drop this  "Remote Exam Live Environment ISO" and move to a browser based remote exam.

Having to worry about the exam environment instead of preparing for the exam is NOT what I was expecting from Red Hat.

Will look for alternative Linux Certification until Red Hat provides a stable Remote Exam ENV.

Hi

How about getting a 10 - 5-year-old ordinary computer?
HP, Dell, Lenovo, etc.
Nothing gaming, nothing fancy, just. an ordinary Probook, Latitude. Something with integrated GPU? There are many of those around for 100 USD. I think it is not difficult to hit a second-hand computer shop with the RE USB stick and try if it boots. Regarding the Ethernet port. Why not get a 100Mbps USB to Ethernet adapter for 7 USD? I think you can even find somebody to borrow the computer from, just for the exam. Besides, this HW can be used for your further education and testing. Personally, I would not take the risk of buying new stuff. It is likely not to be supported. It is not a problem of Redhat but in general. Creating drivers takes 1-3 years for any Linux distro.

Regards
Petr

Yes I can always go the trial and error route like many others on this forum. Spend time, money, fail the exam a couple of times until I get the remote exam env right. I am working as a Linux admin for over 10 years now. I just want to validate my knowledge not go through a frustrating long unstable process just to prove my skills.
I can always look for alternative Linux certification
But thanks for the advice anyway.
