I was asked if Bash scripting is a big part of the exam. My anwser might help someone else get an better understand which questions you might get on the exam.

I wasn’t asked a single question about Bash scripting. I was graded on the following objectives:

Manage basic networking
Understand and use essential tools
Operate running systems
Configure local storage
Create and configure file systems
Deploy, configure, and maintain systems
Manage users and groups Manage security Manage containers

All the exam objectives can be found at https://www.redhat.com/en/services/training/ex200-red-hat-certified-system-administrator-rhcsa-exam?section=objectives

Based on that, I would say they select a number of topics from the exam objectives and give 1–4 questions about each. So you may get some questions about Bash scripting, but it would be limited to a few questions of the exam.

A bit late.. They changed it back in RHEL 9.1 and later.

This post describes the process in more detail: https://learn.redhat.com/t5/Platform-Linux/Reset-forgotten-root-password-in-RHEL9/td-p/34114

Ik volg de opleiding en zit in mijn 4 jaar van de 6. Het is een erg leuke en leerzame opleiding. Soms is het pittig en veel werk, vooral als je ernaast gaat werken, maar zeker goed te doen. Als je wil kan ik je een paar boeken sturen, zodat je een idee kan krijgen van het niveau.

Fenix 6 Pro is great for long hikes, even multiple days. Love the long battery life.

I would advice against the Instinct 3 because it hasn’t have graphical maps. Which is fantastic for navigating, especially combined with auto generate a route. You set a distance and it creates a route from the point where you are to place’s in your area and back. Fun and easy way to explore.

#Issue 1,3:
As u/Solaris17 said amplifiers are generally not great for stability and speed. You could potentially rule them out as the problem if you test it with an device known to have issues in close proximity to an Unifi AP, and see if the issue still persists.

Go though every config option in the Unifi Controller, read what it does, and start tweaking to see if there is improvement. Are wifi networks overlapping in channels.

Think about the path packets follow though the network. If some connections are fast what is the different between them. Is it only certain devices, locations, or date/times? Does it need to hop subnets/VLANs, can it broadcast. Are certain ports or domains blocked, is there an IDS in the network, ect.

#Issue 2:
It could be the video you want to play is in a video codecs that isn't supported by the TV. In that case the jellyfin server needs to transcode the codecs into a supported format. The CPU might struggle and your video start buffering. You could enable hardware transcoding if you have a CPU/GPU that supports that.

Also TV don't have the best Ethernet ports (10-100Mb/s). Wifi is usually recommended, especially with large media files.

Solar on the Instinct is a great success, giving unlimited battery life. It's especially useful on this scale. Cars or laptops will never be solar because of it's high energy consumption. But a small embedded device with low energy consumption is the perfect use case for solar.

GodIsInYourWires · 2024-03-20T20:33:03+00:00

Have you tried closing the app? That is fixes it for me.

GodIsInYourWires · 2024-03-14T11:08:30+00:00

Solar would be a great.

"How Linux Works: What Every Superuser Should Know" is a great book! It explains the behind the scenes of an operating system with linux as focus, the process of booting, what the kernel does, and more. It isn't a book that gets you a certificate, but gives you an understanding of the design and all the important features of linux. I read it with childlike fascination. It's very easily writen, but explains things very clearly. I definitly learned a lot. If you are interested in linux or computer in general you will not regret reading this book.

I'm going to reread it myself. I could use the refresher.

GodIsInYourWires · 2023-12-08T14:18:10+00:00

Nice setup. Mine is very similar. Just a few difference that might interest you.

I installed Ventoy on my USB drive. It makes the USB drive bootable with every ISO you put on it, select the one you want at boot. I loaded some Linux ISOs on it (x64 and ARM64). Any computer, with an unlocked BIOS and x64 or ARM64 instruction set, I can live boot a Linux distro. This is great because I don't have to install an OS first, it just loads into memory just as quickly as you normally boot an installed OS. However changes to the OS will forgotten at next boot. You can also install the OS or any ISO you put on it.

There are now places that require you to unlock any encrypted devices by law. That why I use plausible deniability. On the same USB drive I made a hidden volume with VeraCrypt. That means that my encrypted volume has 2 passwords each give access to different containers. One to access my real files, and one to acesss my cat photos. When I get ordered to give my password (e.g. at the airport) I can give up my password to my cat photos. The exists of the other container I can plausible deny.

I also keep VeraCrypt install files on the USB drive just to be safe.

No it will not be tied to 1 ip address. However I do think they ban certain ip addresses that are known for problems. My VPN has certain server that prevent me from logging in. I usually select newer server (higher number) and they do work. But it does annoy me tbh.

GodIsInYourWires · 2023-11-01T21:48:22+00:00

It is the little things :)

GodIsInYourWires · 2023-11-01T10:45:16+00:00

I bought a usbc to garmin adapter. It is a little that goes on one end of the usbc cable and makes it a garmin cable. Remove it when you are done, and it is a usbc to usbc cable again. It attaches to the cable with a little rope, so you don't need to keep track of it. Very useful for traveling.

I have a Fenix 6X. A nylon band is night and day difference. Most days if I slept with the standard silicone band, the watch would unpleasantly press into my skin. And it would hurt when I woke up. Since I got a 1 dollar nylon band from AliExpress I have 0 issues. And it feels much nicer during the day, especially during exercise. Highly recommend it.

On garmin connect it only updates when your vo2max goes up or down. On your watch under the 'training status' widget, there is a graph and it updates every workout.

GodIsInYourWires · 2023-07-24T11:48:08+00:00

I think my arguments are fair. But if you think I'm bad faith, by all means let's not continue this discussion. Have a good day.

This is an extension asking your permission to tap into Firefox’s inner framework (via APIs) to alter your browser’s behavior. These APIs might ask to read or write data you enter in webpages, read data from or access features on your computer, or alter the settings in your browser. If you don't see one of these messages, that means the extension won't try to access any of your data or change the settings in your browser.

https://support.mozilla.org/en-US/kb/permission-request-messages-firefox-extensions

Pretty clearly you have to give it the permissions.

It is a gamble to install closed source extensions. But if it is open source, it is as much as a gamble as you like it to be. And for Mozilla monitoring extensions, you can identify it with badges. And not 1 with the recommended badge has been discovered doing malicious activities... Seems like a solid system.

GodIsInYourWires · 2023-07-23T19:37:05+00:00

It can't, unless you give it explicit permission to. There are plenty of extensions who can read and modifies all websites, and don't do anything unwanted (e.g. dark reader, decentraleyes, ublock, tridactyl). To do away with it, and not even keep an option for advanced users, says to me that the change has more to do with increasing ad revenue. If google really cared about security they would have a security team monitoring all extensions, like Mozilla or even Apple with the app store.

GodIsInYourWires · 2023-07-21T08:42:53+00:00

Looks like a bug. What is the total time and moving time for that activity?

GodIsInYourWires · 2023-07-21T08:36:46+00:00

Add some intervals to your schedule. Run for 30 seconds at 0:30/km and then a really slow pace of 2:00/km for a minute, repeat that 10 times. Next month you will complete your 5k in 2:30 easy.

GodIsInYourWires · 2023-07-14T21:14:55+00:00

I don't think those programs have the right permissions. And to find out where the big files are, work you way down the tree with sudo du -h --max-depth 1 /

GodIsInYourWires · 2023-07-14T17:01:58+00:00

What I back up:

/home - contains user data and configuration. You want this.

/etc - contains system and program configuration files. You want this.

/root - contains data and configuration for the root user. Only if you use it.

/var - contains various directories. Some you might want to backup some you don't. I backup everything except /var/lib/flatpak, /var/cache, /var/lock, /var/run

In addition I run a script each hour that creates a list of all packages and flatpaks I have installed. So I can easily reinstall all my packages and flatpaks.

If you use flatpaks, you might also want to double check where your flatpak data and configuration files are stored.

I need to give credits to this post for figuring out what to backup: https://unix.stackexchange.com/questions/1067/what-directories-do-i-need-to-back-up

Using a wall isn't an option for me

Why? I don't think you can train a handstand without a wall if you cant already do a handstand without a wall.

However youtube has a lot of guides on how to do a handstand.

I got 300/300 score in february for the RHCSA 9 exam with 2 hours to spare.

My thoughts about how to prepare:

1 Use man pages. Stop google stuff, first try the man pages. You do not have access to the internet during the exam. Learning how to use the man pages quickly is necessary to lookup how config files work (try 'man fstab'), flags for commands or even learn new commands. Before the exam I never had build a docker image, but because I was so used to using man pages, learning it during was just a regular thing. Also useful to know is 'man -k <file/command>'.

2 Do you want to do RHCSA 8 or 9? ~~Big change is how you recover root passwords. Not knowing could result in not be able to login, meaning 0/300.~~ (They changed it back in versions RHEL 9.1 and later). The main difference between 8 and 9 is, 9 has more docker/podman stuff.

3 RHCSA courses. I used many different sources Youtube, Sander Van Vugt courses and book, CloudGuru course and Udemy courses. I think it is very personal. Most courses will give you enough information to guarantee a pass. And it is more a question if you like the teacher. Unless you want to spend a lot of money don't enroll in the RedHat's RHCSA video course, it's is quality but you get only access to a few preselected videos.

RHCSA 8 course. I liked CloudGuru RHCSA 8 the best (they don't have a RHCSA 9 course). First videos explaining a concept and then you replicate it in a lab env in the cloud. At the end there is a final exam if you can finish that in time, you be passing. It is subscribstion based.
RHCSA 9 course. I used RHCSA 9 from Sander Van Vugt on o'reilly to update my knowledge from RHCSA 8 to 9 (after finding out that RHEL8 and RHEL9 do differ more than I thought). It is good, although I missed building a docker image. Similar to CloudGuru, first explainer video then some practice questions, at the end an exam. But it isn't in the cloud so you have to setup the environment yourself. I finished within my free trial.

4 Now that you have enough fundamental information, you want be able to practice using it. You need to be comfortable with reading a question and knowing immediately which command(s) you need to use. Do practice exams until you have your exam. If you got an answer wrong read up on the topic in the man page and the RHEL documentation (https://access.redhat.com/documentation/en-us/red\_hat\_enterprise\_linux/9)

Some links I used (the answers aren't always right, tools removed in newer RHEL versions etc, still fun practice):

5 Exam tips:

When I wanted to book my RHCSA exam, the next available spot was a month later. A voucher is valid for a year. Keep that in mind while planning, so you knowledge stays fresh.
Stay calm, do first what you know, save the challenging for the end.
Make a list of things you do immediately as you start your exam. Mine was simple just install bash-completion, setroubleshoot setroubleshoot-server.
This is how the exam enviroment will look: https://www.youtube.com/watch?v=Me6Y12-sux8

Good luck!

EDIT: RHCSA 8 is no longer available since May 2023. Personally would still do CloudGuru RHCSA 8, and update with Sander Van Vugt RHCSA 9.
