Hey dexter should i take the exam in online mode or offline because there is no red hat exam center in coimbatore i should go to chennai. will i face any trouble in online mode also what can i use mac for exam taking, what gpu specs is needed?
I got it,
when done adding context to /test dir after that when doing curl locahost/index.html" I'm getting message "you do not have permission to access /index.html" even though I have given full permission on the file 777, please let me know ASAP I will be taking the test next week. Thanks
Have you changed the SELinux context and edit the configuration file?
I just love your straight to the point vids. Thank you
Man, had I seen these from the get-go I would have passed my test the first time! Studying for it now and your videos are perfect for me. Better than Red Hat Learning sub because these are no fluff. Thank you! 🍻
Nice, thanks
Lot of love sir ji ❤🎉
Thank you! It's been awhile and I needed a reminder.
i need script
Hi great videos, thanks for your help, I only have a small suggestion if you can add the video tutorial number to the description of each video like {RHCSA Exam Questions || Users and Groups || ACL || Sticky Bit || SGID || RHEL 9 -Tutorial video 6} or something similar, sometimes it's easy to remember the video/tutorial number where you have left instead relying on youtube playlist to show where you have left.
I can't thank you enough!
Q1 -> A, Q2 -> C, Q3 -> b, Q4 -> a
Every time I'm downloading the docker httpd image as a user "syed" the images goes to root profile I have ssh to my self "syed" what can I do, becasue I can not do any thing with the user profile, please advise
Need to see how you are doing it..can discuss over video call
wow thanks
Hello Dextor, For systemd containers do we use podman generate or we use quadlet?
Although quadlet is recommended but podman generate still works and does the job
Thank you Sir for giving the knowledge. Your videos helped to understand the topics better. I passed the exam.
That's great.. congratulations
Sir, by breaking the root password, does it affect our files?
No
Q1,mkdir -p K{1801..1810}/R{1..10} Q2 touch F{1..10}
internal segmentation
Hello Dextutor is this for RHEL 8 or 9 ? because there is the /etc/auto.master.d/ dir to story the autof maps
Yes it works in both RHEL 8 and 9
Life saver❤❤
You also need to run "loginctl enable-linger" to ensure that the service automatically starts after reboot
Try without that and enable using systemctl
loginctl enable-linger <username> is requried. Othewise it will not start the container service on boot. It will run from command line but will be failed to start on boot.

R U using RHEL 9, for this question? when I do man vdo nothing comes up on RHEL9
Refer the updated video in the playlist for VDO in RHEL9
I worked out the practice question and got, AWT = 6 and ATT = 10.6 Is that correct?
great explanation...
Very helpful. Thank you @Dextutor for sharing
Glad it was helpful!
still not resolved
Are you able to ssh the server machine from client?
good morning, is this good for the rhsce 8 or 9 sir?
Exam environment is same for 9 also. So it is relevant
@@dextutor thanks!
VDO not VDU
Guys, for changing the port, the semanage-port man page literally gives the exact command that is needed. It's down at the very bottom. No need to memorize commands.
The auto generated English captions are hilarious. But unfortunately, I can't use sound right now and I have no clue what's being said
cool dude
love your content !! veryhepful
I tried your script and it didn't work I have to eliminate $2 if [ -d $1 ]; then echo "Directory Exists" else mkdir $1 echo "Directory created" fi
