Resetting the root password without an autorelabel does not work. I have tried using restorecon /etc/shadow and this does not work either. It seems that the most reliable way to correct the SELinux context of /etc/shadow after changing the password is to relabel the entire filesystem... this, unfortunately, takes time.
The password reset didn't work on 8.3, any ideas? had to do a touch/.autorelabel even if i'd done enforcing=0 after rd.break. i notice my grub config has additional entries compared to yours too "ro crashkernel=auto"
Thanks Colin for your videos. Immediately after reboot and logging in with the new password, do #restorecon /etc/shadow and as always, eventually make sure that selinux is in enforcing mode.
Hi, thanks for the video, very informative, I'm not that acquainted to nmcli though and isn't ifconfig deprecated? Shouldn't ip command be used in place of it?
@@compsecgadgets to be honest I prefer the output from ifconfig too, took me a while to switch! What about nmcli, can I use ip for that too? In that case I prefer the latter, I find nmcli confusing and overly complicated but maybe that's just because I don't use it.
@@compsecgadgets thank you for your reply. I was just wondering whether it would work or not. Thank you for confirming and letting me know that your method is faster. I really appreciate it!
Hey there, awesome videos, really helpful I have a question though... Is packet forwarding still in the exam? I have tried your solution and everything i could find on the internet but no matter what I try it just won't persist after boot. I get always 1. Packet forwarding was enabled by default Thanks for any answer in advance :)
Even after editing grub options and doing ctrl+x as shown in the video for Q1. my system is booting normal. its not going into emergency mode.. am I missing any step? plz let me know
had the same issue, i think the boot process does not work the same with all hypervisors or architectures (arch64 vs arm). I could not get it to run properly w/ my M1 mac running utm and RHEL-9 arm version but could with my older intel mac running virtualbox with the arch64 version
Hello Mr. England, Hope you're doing good. I have tried the rd.break process with enforcing=0 and it worked for the first time. However, after I reboot I couldn't login and it says incorrect password. I would really apprecite you providing a solution for this. Thanks and Regards, Vamsidhar Galenki
Hi Vamsidhar, All good thanks! Hope you are good. It appears Red Hat have changed their advice more recently back to following: access.redhat.com/solutions/3889671 Kind Regards, Colin
Same happened to me when I used the mount -o remount,ro / method. I ended up doing the old method which was covered in a prior video where you reboot the machine and run restorecon /etc/shadow
After You login with Your newly set root password, execute following commands: restorecon -Rv /etc/shadow setenforce 1 it shall make Your password reset proof
The missing line before exiting is this: sh-4.4# touch /.autorelabel Run that after changing the password, then instead of reboot you can simply "exit", then "exit" again and it will resume from the break.
During putting rd.break at the end of the line, if I change the ro to rw it will mount the system not in readonly mode but in read/write mode. Any disadvantages of using that? Also, in our classroom instruction we were taught to put console=tty1 with rd.break, is it manadatory?
@@herlanyuswanul6331 Did you fix this? I'm having the same exact problem as we speak. I pinged google and amazon and it was a success. Is the repolink inactive now?
Hi, Excellent video. But I have a frustration where I am unable to obtain the repositories. even thought I have the AppStream and BaseOs configure and enabled, no repo. Can someone be an assistance?
Are you setting up online repo or it's from media disc. If it is configured from local media disc then you need to mention path in the both baseos and appstream file which are located /etc/yum.d/repos
After some research, it was selinux making some files read-only so no password will work. If we don't do the enforcing=0 and do the touch /.autorelabel, then this problem does not show up. I would not recommend doing enforcing=0 as it also makes the selinux permissive on the other side of the reboot.
@@andthesunsets There are a couple of steps you have to perform after changing the root password if you go the enforcing=0 route. You need to restorecon /etc/shadow then setenforce 1 to reenable selinux. I've been doing it this way and experience no issues.
Thank very much, this is helpful for me. Hope they will give 2 separate different link for both repository( BaseOS and AppStream) for my exam that day. 🙏🏼

As part of the original build there were two interfaces on that server.

i didnt put + to add secondary ipv6.address at 14:45 min. or is that the right way?
If you are adding an additional address yes you need the +. It cannot hurt to have it added either way

Hi, The exam was taken on "mother" Redhat with KVM guest inside where the exam happened? nor with virtual box. Thanks in advance.
Kvm is essentially the same thing but on Linux. Virtualbox is used because most of us have Windows Desktops 😀
@@compsecgadgets Yes of course, I am aware about it since the beginning, but real exam is happening on KVM nor Virtualbox? Thanks.
As per here: www.reddit.com/r/redhat/comments/b5sk8n/kvm_for_rhcsa/
Why not drop "setenforcing=0" do everything the same way but do "touch /.autorelabel" after changing the password and then reboot?
Auto Relabel takes a very long time, in the exam I would suggest you don't use it.
