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

[gregmcc]

Remind me of this.

No it’s an alias like I said.

symbolic link is something entirely different relating to the file system.

Aliases are configured in your shell (bash) as sort of shortcuts yes.

You'll find on most systems that "Is" is actually "ls -l” and “vi” actually is running “vim” and a great many other standard ease of use things like that.

so ls automatic does long list so you dont have to use a switch,makes sense and quicker

On some distros not all.

But you can easily add it to your Bash Profile with the following.

alias ls=“ls -lrt”

You’ll likely find a couple there or in .bashrc already.

As you become a Linux nerd you’ll probably find yourself having a default config you want to load up everywhere as you go over time.

Now i am dying to ask..lol is this allowed when you are a system admin cause it dont look like this will impact load on servers right.

It’s your own user profile.

It’s like configuring your desktop just the way you like it, no different.

You are way too concerned about load on servers, literally nobody cares about that from a user point of view, it’s simply inconsequential.

Servers are specced to do their jobs properly, users aren’t restricted to maintain loads. And in the modern world most things are built to auto scale anyway.

Also, please for the love of god stop throwing “lol” into every post. It doesn’t belong there, you don’t need it and it makes you seem very juvenile.

sorry for asking this as i read on reddit someone use a program where you have 2 gpu,s and can run 2 distros on separate screens from one pc and it seems natively.I think its called glass something.Do corporate use things like this.
My homelab i crashed it and want to start over.This is what i have now in hardware
1- 2 laptops
1-macbook pro late 2008(ssd upgrade and ram-mojavi dual boot with catalina)
1- jailbroken ps3
2 monitors 50 inch and 23 inch
1-desktop pc with gpu gtx1080ti and gtx 1050ti
What suggestion would you do if you wanted to start fresh with homelab
I asked this on other sites and everyone gives different answers, but i am having a problem with the network cards as most do not support realtek hardware

The reason why i ask this load stuff cause i is sytem admin must control this this by deleting and killing processes.I just thought this is very important

Stop trying to do 50 things at once. Do one thing and do it well. The reason you aren’t progressing is this constant jumping between stuff.

And no there is no place in business for running two distributions on the same box at once. Why would anyone do that? Besides the fact it would have been standardised to one system only.

Most servers don’t even have screens or keyboards attached and are hundreds or thousands of kilometres away from the admins.

My advice is do this…

Setup Ubuntu Desktop on your workstation or switch to the MacBook as your primary working system. Choose ONE, not both and use it as your daily so you can learn from it.

Now install Ubuntu Server on the other machine and get SSH working from the workstation and then plug out the screen and keyboard.

That’s how the real world would work. Now you do everything on the Ubuntu server from terminal in Ubuntu Desktop / MacOS over SSH and that’s what an admin would operate like.

Now go setup some network shares on the server. Maybe add an additional drive and expand it into an LVM etc.

These are the things you’ll do in the real world and exactly what the RHCSA would test against.

If you need to change distro to make things work or reinstall the server you aren’t learning. You are just repeating the same mistakes over and over again. In the real world you don’t reinstall the server you fix the existing one, that’s where you learn.

If you can procure the RHCSA work book that’s the best place to start Linux.

So the macbook is my terminal so to speak.Ok gonna set it all up like you said and i will update.Also hypervisor 1 stuff.like proxmox and esxi. etc. and apache and nexcloud is the that the next lesson or is that not part of this tutorial..

You have a very warped perception of what an admin does.

Nobody sits around all day watching processes and killing them and no it’s almost never killing processes to manage load.

If you have to manage load then something else is broken or misconfigured or the server is specced badly.

Also a server running at 80% the whole time isn’t a bad thing. What’s the point of an overspecced system running at 20%? That’s just wasteful.

I do not have alot of time left, believe me when i say this time works different for me.Yes i know i am all over the place but i got maybe 3.5 years to have some sort of qualification in IT amnd at my age remote work will suit me fine

I gonna stop watching that fool linus tech on youtube.

Anything can be your terminal. You just need SSH.

Others will disagree with me but I’d not even waste my time with learning on premises technologies like this, unless you have a personal use case for it.

Learn Linux on bare metal, then learn how to run containers on it. Setup your own Plex/Sonarr/Radarr/Downloader in Docker. Setup AdGuard for your home network etc in Docker.

Then learn how to do that in the cloud with AWS/Azure/GCP.

So then go for Red Hat Certified Administrator and ignore everything else until you’ve got that done.

Do Red Hat Certified Engineer and then pivot to doing AWS.

Then you’ll have work.

true i dont know cause i need to see the screen what they do all day and there is no youtube video that shows the day in the life of a admin and show his terminal.i need t osee live or shadow to understand what is going on.

great advice....just want to understand linux cli fully,i read on the forum guys even after 20 years are still learning.Anyway gonna look into redhat and set up homelab.thank you so much for taking the time to read my strange post.

live love life linux......we are legion

tell me did we not play dmz together in warzone and i still asked about you pentesting...ok wrong guy

100% you never stop learning.

There are simply too many different flavours and variables involved with thousands of people contributing to an open platform.

Big part of being a system admin is your ability to interpret based on experience.

Often you’ll work on a system someone else might have configured and you need to work it backwards to figure out why they did some things the way they did etc.

In a perfect world there would be documentation but this is rarely the real world case.

It’s also very rarely you’ll find you only sit and only work with one thing all day, depending on what business you are in.

Years ago I ran a couple of Ubuntu servers but also did the MySQL database admin and the ESX platform along with the vSphere backup and replication as well as the local Asterix/Freeswitch server for VOIP and then at the same time ran a massive IVR platform in the Netherlands and a distributed network of Mikrotiks and other networking hardware.

After that I just did *nix all day but as a managed services partner it would be all over the world jumping from RedHat to SunOS to HP-UX to Centos in clusters etc and all sorts in between all with their very own bespoke tricks and tortures.

Now I don’t really get too hands on any more because I manage people but I indirectly oversee a large AWS environment mostly running Amazon Linux and everything in containers in between with basically nothing on premises and even networking in the cloud.

Point is adaptability is what it’s all about and it’s going to be very different from one place to another.

Don’t think so.

I’ve only ever casually dabbled in ethical hacking and pen testing.

I’m more the one getting pen tested and audited all the damn time.
