No need to respond as I will not be checking for updates. This form is clearly a weak part of the itpro.tv offering.

Good to know. Thanks

Thanks for replying. Yea I might have made a mistake during partitioning disk

Thank you very much Mr. Pezet. Your no-nonsense edutainment methods are much appreciated. Have a great rest of the week!

Thank you, Daniel, for your reply.

I already post the same subject in the forum.kali.org.
In their forum, I have seen that I am not alone with this problem, many others are in a similar situation.

I find an intermediate solution: I create a new user account to continue my learning of Kali distro without this annoying situation.

My knowledge in Python is not enough yet to change the script to correct it, but eventually, I will do something to manage that.

I am a newbie in IT training for one month, but I find it as Mr. Spock said "fascinating Captain"!

I will let you know the development about that.

Learner in progress,
Sylvain

@Ronnie-Wong

Thanks Ronnie! I was thinking that it was just a mismatched entry on the part of Kaplan, but your explanation of the origin makes sense.

I have the LPI Linux Essentials. It's a "rounded off" exam so just work on using the terminal as much as you can and you will be fine. Also learn about how the Open Source community are and the licenses that goes with it. Wish you all the best in becoming a real Linux Professional, the LPI are great to have.

Not a great idea making your user God.

@Bablu-Kumar,

Way to go! Restarting the service a good troubleshooting step.

You will find less issues with Intel on implementing software.

LVM has the benefit of growing the filesystem later if too much space is being utilized.

But standard would be okay too, but if disk was filling up, you cannot grow it as easily as a logical volume

Webmin has some additional dependencies beyond just the core Perl package. The error indicates your are missing the "perl(Encode::Detect)" dependency which is not installed by default with Perl. Try running the following command to see if it resolves your issue:

yum -y install perl perl-Net-SSLeay openssl perl-IO-Tty perl-Encode-Detect

It is a great certification, but it is not very popular. HR managers recognize the Red Hat certifications and CompTIA Linux+. Once you get past the HR department, you'll find that the actual IT staff recognize the Linux Foundation and LPI certifications. I usually recommend RHCSA or Linux+ for getting a job, and then the other certs for moving up in a job you already have.

Interesting. That article is for Ubuntu 14.04 so it looks like the solution has been around for quite a while. I'll have to check it out. Thank you for posting that.

The "Linux Security Techniques" course is the only one dedicated to Linux security, so you are in the right spot. You can find more security episodes sprinkled in with the rest of the Linux training. Check out the following shows:
CompTIA Linux+ (XK0-004)
Red Hat Enterprise Linux 8
LPIC-1 Linux Administrator (102-500) I actually recommend you use both of those distros. Right now, there are two major players in the Linux space: Debian and Red Hat. They both provide you access to the Linux kernel, but they package different tools with it resulting in a different way of doing things. For example, Debian, Ubuntu, and Mint all use AppArmor for application security, whereas RHEL, CentOS, and Fedora use SELinux instead. If you already have a job supporting a particular Linux distro then you can stick with that, but if you are just getting in to Linux you will benefit from learning both ways of doing things.

Pierre,

There are plenty of ways to do what you describe, but the "Red Hat" element limits your choices pretty heavily. Red Hat does not support ZFS, BTRFS, Boom, etc. This is mostly due to how inconsistent those tools can be and they default to supporting only tools that are reliable, tested, and tried and true. As frustrating as LVM can be, that is what we are left with if we want support from Red Hat, but doesn't entirely solve the boot problem.

Their recommendation is to test updates in a lab prior to rolling them out to production infrastructure. If something goes wrong, restore the system from a system backup (using dd or a similar tool). I wouldn't expect that to change anytime soon. Today's focus is on rapidly deployable images using automated deployment suites like Terraform, Ansible, OpenShift and Kubernetes. In those scenarios, the containers don't take kernel/boot updates and can easily be shifted to another system in the event an update to the host OS goes bad.

@Bedrock1977,

I cannot tell you this is the most efficient way to do it but it may work and depends on if find in your distro has the -newermXY option.

For example:
find /media/storage1/data/ -newermt 20190101 -not -newermt 20200101

the m and t options here are for modification and reference is intepreted as time

then you can use the mv as stated by your professor as well.

There are more than likely other methods and I should say better methods.

Hello Ronnie,

I opted out of using CentOS for the time being, at least through Google Cloud. I purchased an 8 GB Raspberry Pi 4 device and have been using different SD cards, each with its own Linux distribution. It's worked over very nicely!

Thanks for your help,
Chris

Linux software RAID works quite well, but keep in mind that RAID will not protect you from accidental deletions, just disk failure.

@Don-Pezet has the right idea but I believe he wanted to say RAID-1 (mirroring) instead of RAID-0 (striping).

Keep in mind that you will lose the capacity of at least one drive when you deploy RAID.

RAID 0: Striping. NOT REDUNDANT. Great choice when performance is more important than reliability (video editing working drive).
RAID 1: Mirroring. Capacity of one drive.
RAID 5: Striping with Parity: Minimum three drives. Capacity of number of drives - 1.
RAID 6: Same as RAID 5 but with two parity drives. Capacity of number of drives minus 2.
RAID 10: Striping + mirroring. Capacity of number of drives / 2.

As Don suggested, RAID-1 is probably the right option.

Any properly paranoid shop will use both backups (protection from accidental deletions) and RAID (protection from disk failure).

@Logan-Sims,

The original source doesn't get changed by any one. Changes to the code is controlled by version control. Probably the most popular usage of it is git and github. For example I, as a developer (which I am not), do not make changes to the code but get a copy of the code in a branch. I can modify the branch but not the original code. Any submission to change the original code I choose to make would be reviewed and then decided whether to accept some of the changes, all of the changes or none of the changes.

This has been a very effective means at controlling the original code so that the software doesn't get worse from intentional or unintentional changes.

Other's that know details about this may jump in and provide more details.
