Finally, an English speaking person explaining RedHat properly

My lecturer took 1 hour to explain this, you did it in 8 mins

[vitaliykondrenko]

Thank you. Realised what I was doing wrong after watching your video.

[nilanjanmandal]

Amazing! you just resolved my peoblem. Now I am able to connect. Thanks a lot

[Diegunio]

Can somebody explain please what's the point of installing SSH server instead of connecting with in built ssh via putty for example, as a machine is just a local one?

[fahmiresali]

when I tried NAT port forwarding options I cannot access and getting connection timed out. Do you have any idea what may be the reason?

[LeserGD]

If you run VM in headless mode this doesn't mean that GUI isn't working.
It means that you aren't connected to VM console. Processes responsible for GUI are still running

Are these courses still viable for the current RHCSA and would it work just as fine to follow through with CentOS 8 instead of RHEL?

please how to get centos 8 linux or higher to study rhcsa

[amantiwari]

does it work over the internet ? Or just within the local network ?

How Do I Download Kitty and have it set up the way that you do. I haven't seen it in the beginning of this series, until you just pulled it up

[GeorgeTimmermans]

Great instructions. Easy to follow. When I attempt to SSH via Kitty I get an access denied when entering my passphrase. I can get a SSH connection within my VM. Any suggestion why this might be happening?

[YanickGirouard]

Why are all courses on RHEL always using the GUI when nobody uses the GUI on servers in enterprises? That always puzzled me. I did my RHEL 6 RHCSA many years ago and was very surprised that we weren't even going through the command-lines for anything other than basics unless you asked the teacher "on the side", and the final exam didn't require you to know them either.

[noranseliem]

firewall-cmd --zone=public --permanent --add-service=ssh
last command in video caption "=ssh" not "-"

[michaelderei]

on the first video of the course you did NAT Network and here you did NAT. also it's neither RHEL8-Server nor RHEL8-Client you created on the video before. it's confusing to know what's going on

Thank you so much I realy like your videos but the thing that I don't like, you are doing everything through virtual box.I don't think that in the exam we will use virtual box and for most of us an example vmware is much more easy and fast.I didn't even enabled all the settings that you did on first lecture and this but there wasn't any problem with connecting through ssh.I did what you did on this lesson now and it still works.I think you had to dk them because you are using virtual box.I am not against that but it is just a little bit bad for who use vmware.Also you are doing port forwarding through virtual box i wonder why...You change the port number from you terminal and this must be good information for everybody..

Ive watched the first two videos and a lot of times it seems you are just showing and not tutoring. You write certain commands and dont say what they are for so it just looks like a cram and pour video. Kindly clarify more
