Hi,
How I can get access to AWS with AWS educate pack? Is it possible?

Type of error

• Add relevant info about ufw install: no need to install as it comes by default since Ubuntu 8.04 LTS

Proposed solution/correction
Add : "Ubuntu 8.04 LTS introduced ufw, and it is available by default in all Ubuntu installations after 8.04 LTS."

Additional context

Using -f with tar while creating archive is essential. The document uses the following:

tar -cvzf myinits.tgz /etc/init.d/

I accidently used tar -cvfz ssh.tgz /etc/ssh and the the archive file named z

~ # tar -cvfz hello.tgz /etc/ssh/
tar: hello.tgz: Cannot stat: No such file or directory
tar: Removing leading `/' from member names
/etc/ssh/
/etc/ssh/ssh_host_ecdsa_key
tar: Removing leading `/' from hard link targets
/etc/ssh/ssh_host_rsa_key.pub
/etc/ssh/ssh_host_ecdsa_key.pub
/etc/ssh/ssh_import_id
/etc/ssh/sshd_config.d/
/etc/ssh/ssh_host_ed25519_key.pub
/etc/ssh/sshd_config
/etc/ssh/moduli
/etc/ssh/ssh_config
/etc/ssh/ssh_config.d/
/etc/ssh/ssh_host_rsa_key
/etc/ssh/ssh_host_ed25519_key
tar: Exiting with failure status due to previous error

~ # file z
z: POSIX tar archive (GNU)

So, I think we can add a NOTE that the -f considers anything after -f as the name of the archive that needs to be created. So, we should always use -f as the last flag while creating an archive.

Please always specify the day of the lesson (i.e. Day 17, Day 0 AWS) in the title of the issue.

Proposed solution/correction
Change reference to 20.04 to simply "latest LTS" to avoid correcting the document every time the version upgrades.

This lesson first has users check if vi is installed on their system. And it usually is by default on most major Linux distributions. But then the rest of the lesson uses vim which isn't always installed (or aliased) by default. This can cause some confusion if new learners are expecting vim commands to work.

Describe alternatives you've considered

Unless we're going to have learners install vim on their systems at the beginning if the lesson we should use vi throughout. My opinion, is because vi is most often installed by default it will almost always be available. And since they are just learning the basic vi modes and motions which also applies to vim, there's not a distinct reason to have them install vim or explicitly use vim.

Counter to this is that vimtutor is referenced later on in the lesson. We could have learners install vim at this point in the lesson, or to reduce overall confusion just have learners install vim at the beginning of the lesson. In either case we then need to have documented support for installing vim on all major Linux distributions which could add maintenance overhead to this lesson since we would then need to maintain our own version of vim installation documentation.

Another option would be to move vim installation and vimtutor to the extension section of the lesson.

Additional context

Copied from user's comment in the Discord server #suggestions channel:

I had some trouble on Day 6, it says to run vi which exists on my Debian 11 VPS . It then says to run vim testfile, but my system doesn't have vim , only vi which seems to run vim. also, further down in the lesson it says vimtutor should always be installed, on my VPS it was not

Additionally to the bash scripting it would be nice and probably sensible to also talk about orchestration frameworks like ansible, cloudinit or terraform.

I might be able to write something like this, but I'm unsure about the location it would fit the best.

I could use a little help figuring out how to disable the iptables firewall that comes installed on the IBM Hyper Protect Virtual Server (HPVS): https://cloud.ibm.com/docs/hp-virtual-servers?topic=hp-virtual-servers-protect_vs

EDIT: I've been experiencing some weird discrepancies with IBM, such as the commands "less" "man" etc disappearing, so I can't recommend using it.

Mod mail from u/linux26

Good tutorial! but a few things:

but in the first line and followed by a "!"
The shebang doesn't just have to be in the first line, it has to be within the first two bytes. https://stackoverflow.com/a/3009280

Also consider using a here document instead of echo on multiple lines. cat << EOF

$() is better than `` since the latter gets really complicated to nest.

If anyone was having trouble setting up multifactor authentication for SSH with the instructions above like I was, these instructions helped me to nail it down:

https://www.techrepublic.com/article/enable-ssh-2fa-ubuntu-server/

There are some important distinctions between the Ubuntu 16.04 that the listed instructions are based on and the current 22.04 version that you might be using.

It's important to check which version of Linux you might be using! I'm LEARNING!

Nice catch!

Because Reddit is a mess right now, it would be nice to have this community on Lemmy as well. Another alternative is kbin, but I'd rather have it on lemmy.world.

More than a couple of complaints about this on Reddit.
Yep, it seems that in the "minimal" image only the systemd journal is available, the file auth.log is missing.
To get it back need to install rsyslog:
sudo apt install rsyslog

Add a note to Day 8, when we first touch auth.log, to cover it.

I'm currently remodeling Day 0 to reduce the amount the files but to open space to add more cloud providers like Oracle and Linode.
Also a section for local servers, as it is requested every month.

When running the Build bash script, the following message is output in the terminal, despite the prerequisites (commented within the script) having been met. Perhaps the missing file is a simple one that can be included in this repo?

Mateusz Kita: thanks, it's always good to make a correction, in any way applicable
I think it would be also good to mention potential "corrected link", e.g. https://ubuntu.com/server/docs/how-to-install-apache2

Thanks Verenthi for catching that and thanks Mateusz for the correct link.

Something to update possibly. The directions stated " type /sun to find the first instance, then press n repeatedly to step through all the next occurrences" - I found out after you type in what you are searching for you should hit enter before looking for next. I had /sunnnnn in the search before I figured out what I was doing wrong. Day 6 complete! Loving the course.

On the SSH hardening article the steps for setting up 2FA are incomplete. At least for the default setup of Digital Ocean.
Expected behavior
It should be possible to successfully follow the extension exercices/resources.

Proposed solution/correction
The following article worked for me
https://www.digitalocean.com/community/tutorials/how-to-set-up-multi-factor-authentication-for-ssh-on-ubuntu-16-04
if it also works on the other cloud providers it could be added as further extension.

Additional context
I understand it's an external resource and I'm not sure if this should be fixed.
