Can you install your own software when being an IT system admin

The sooner you get to grips with vi/m the better.

Many other tools use the same syntax and shortcuts.

Forget the GUI exists.

Sounds like you created the user just fine, but didn’t create a Home folder.

What makes you think the user wasn’t created!? All the signs are there that it was.

User <> Home Folder.

if you create a user does the home folder get created immediately ,also if the user was created but no password was set and you use chage -d 0 will that user be visible when logging out and back in.Cause this is what i did.
I tested this on both laptops each its own distro and i never got the new user in the login screen.This is strange and i wanna send this problem to the tutor guy.Have a enjoyable day is what its all about and no stress

You need to tell it to create the Home folder otherwise it’s just a normal service user.

Code: 
useradd test -m

If the user shows up in /etc/passwd then it exists.

Login would only be possible once a password has been set.

Code: 
sudo passwd test

Login screen is something entirely different. You are already going off track checking if users exist based on that.

They need to be added to specific groups for the GUI to work.

ah yes now i understand,i know where i made the mistake.i had to say passwd XXX then set a password then use chage command.i tried that now and i got to see the other user, thanks again
 
Guys sorry , i am in my studies at chattr section.Now i lsattr a file and there is a --E---- in the file,Now it stands to reason i use chattr -E file.txt.This does not work to delete it and the manpage says it means encrypt.
I am the root so what gives.
Also so far i am loving redhat admin, god i want to finish this course.
 
hi guys
i have a very important question to ask.As you know i am studying rhelsa and i am at the stage where something is very confusing.I need advice.To change the dns nameserver i can do that but to configure a static ip address iam lost cause there are 2 ways to do it and the instructor uses the ifcfg-rh file to edit in vim,but there is now a change which i read that the configuration for networks are now in etc/Network manager/system-connections and this file is the new way.
Both are supported to config the network setting so which what do use .The networkmanager or the network scripts.

Use the tools.

Often the files will even tell you not to use them any more because they’ll be dropped on reboot etc, due to being used in different versions or mid transition.

nmcli or nmtui

i did some research and the next chapter is on nmcli..etc.i also read that on redhat the scripts are still supported but the new network manager in the etc is also the same.Its a choice as long as it comes to the same solution.I see when i reboot the dns goes back to normal.I do not have that ifcfg-rh file/I only got the readme.I need to figure it out why i dont have that file.

Use the tools.

Much faster in the exam and impossible to cockup with a typo.

DNS is likely in /etc/resolv.conf but I can’t remember off the top of my head.

I think nmtui lets you set them all with a UI so pretty painless.

correct resolv.conf is the file to edit the dns but it resets after reboot so the nmtui is the real deal,thanks for the insight.

nmtui is awesome but also consider using cockpit. It has most of the basic things you need for configuration of the OS.

i think i am only allowed to use nmtui,the course does not mention cockpit.let he check rhel if that's preinstalled.
Ok cockpit is not installed on rhel as i am getting command not found.

You are allowed to use anything.

It’s only the final state of the machine that matters and whether it ticks all the boxes they asked for.

Only still this to study then redo the course all over again and then again and again and again.

I must admit that this is really hard and using tools instead of vim and nano is much easier. and quicker

vim and nano are essential.Remember you might be learning for the Red Hat cert , but commands like nano and vim are universal , and are used in all linux distro's.

I am busy studying linux, its been 4 months 2 hours a day or 6 hours over 2 weeks.yes i know its slow paced but i am trying to follow a dream of becoming a junior sys admin.I dont care about money as i said in a previous post i made a while back.Just wanna follow a dream late in my life,I was wondering in the study guides and videos they sometimes install software to help them likeTOP in linux is ok but i see a guy installing HTOP and was wondering is this allowed in the work place cause servers need as much resources as possible with no load.So if there is software via repos that will make your job easier is it allowed to install it.I mean i see alot of cli software that can make it easier t0 administer most task.Can someone explain what can be done and what cant please.Dont want to hog resources .Its another thing to do it on your homlab but in the real world how is it.
Thanks and sorry for the grammer and no new para.

A system admin cannot install random software on the server without the company's approval.

1. It could cause licensing issues and fines.
2. It can allow for hacking into the server
3. It can take up resources meant for other tasks, which can slow down business productivity
4. Any outing can cause business to loose money, this will most likely get you fired.

So no, you cant randomly install software which you think may be good, it has to go through architecture, then testing and certification, and so on. If you go ahead and just do it, they may happily fire you for putting their business at risk.

We had someone install photoshop on a desktop without licensing, Adobe that checks our environment for licensing scanned that it was installed for 9 years. We got slapped with R35k per year x 9.

The staff member was fired, and the loss incurred was deducted off his pension.
