The repo of RHCE-9.3 Lab Environment cannot be reached by other servers

[wanderingadmin]

Hi there,

I am using the RHCE 9.3 Lab Environment, and I found that all labs that requires installing software packages from a repo can neither be prepared properly nor finished correctly. I'm showing rhcsa-rh124-review3 as an example (sorry for the photo quality):

I've ensured all VMs are up and running, as follows:

By checking the repo config files of workstation, servera and serverb, I found the content server is set as the repo source, and the /etc/hosts file indicates it's the same server as classroom. I can login to classroom via ssh from foundation0, but not from workstation,servera, serverb.:

Judging by the network topology, I think something might be wrong with bastion, but I'm not sure what to do with it yet.

My foundation0 is an VMWare image provided by my training agency. I've never tampered with classroom and bastion, and reverting the image to its initial snapshot does not solve my problems. My agency said I should wait for an official update as they couldn't fix it either.

Any suggestions? Thanks!

tl;dr - delete and recreate the lab environment and try again

longer answer: The fact that the start script had an issue indicates a deeper problem in the lab environment. I just created the lab environment, and ran the relevant lab start script without issues. I then successfully completed the task to install zsh on serverb indicating the appropriate repos are indeed available. Rather than spend a lot of time trying to troubleshoot a problematic instance of the lab environment, it is likely better to delete the existing lab environment and create a new one.

Hi, thanks for replying. Do you mind if I ask how should I delete my existing lab environment and create a new one? Is that something I can accomplish on my foundation0 machine, or should I try to redo everything starting from creating the entire classroom installation media?

I saw you mention elsewhere to "Click on the "Lab Environment" tab, then click the "Delete" button" but on what interface/tool can I find such tab? I couldn't find such a place.

Thank you!
