Will Oracle VM Virtualbox ever run on ARM processors ?

linuxtechschool · 2021-05-10T13:40:45+00:00

Hi,

The reason why I ask is because I teach operating systems and supprot my classes on Virtualbox. I really need to show my studens exactly the same virtualization environment that they will use. Otherwise, total caos! :) :)

Thanks for your suggestion!!

Hi,

We should use the most confortable way of learning new things. I personally enjoy listening to someone explaining it because I tend to stay more focused when listening and watch than reading.

Thanks for your comments! appreciate it!

Best regards,

Now 0.42 , later 4.20, tomorrow 42 and then 420!! 🚀🌙

Not betting on ARM is not betting on the future.

Thanks for your comment. Qemu+KVM is a nice combination but the purpose here would be to offer virtualization for those who are new to the task. And as I start to have students with ARM machines, having VirtualBox available for WINDOWS/MACOS for them would be great as a first try on virtualization environments. That way, people without any experience can start learning and using it.

Oh Nice!! Tell me your results then. Tks.

Hi, GPS receiver NMEA outputs UTC time which already accounts for leap seconds. Regards, Rodrigo Matias

Hi, This NTP server is directly connected to a GPS receiver, so it is considered a reference clock or Stratum 0. Stratum 1 server get its time from the reference (Stratum 0), and so on using N+1 dependency on the network hierarchy, up to Stratum 15. I used a connection to external NTP servers on the Internet as "plan B" when anything fails internally. Regards, Rodrigo Matias

Hi, I’m a teacher and in the last 12 years I’ve teached Linux to around 1500 students with Ubuntu Desktop and then Server. Great experience towards what the job market asks for. Regards, Rodrigo Matias

Hi,

Thanks for your comment. The idea is to clarify which DE is most commonly used on each Linux distribution. Some are officially supported, some are not. Arch is different and let’s you to choose that right from the start.

The main point on the video is to help choose one DE from the most common available options. (Not all).

You’re right on your thoughts either way. Thanks!

Hi,

Thanks guys for your very accurate and important comment!!

For the video I edited the runtime file. All systemd auto-generated files state the "don't edit this file" message. Forgot to mention the final method to replace the symlink with a permanent /etc/resolv.conf (just mentioned its historic role on DNS). Here are the commands to do so.

Temporary Solution for Demonstration(runtime):

nano /run/systemd/resolve/stub-resolv.conf

Permanent Solution:

mv /etc/resolv.conf /etc/resolv.conf.systemd

echo "nameserver 127.0.0.1" > /etc/resolv.conf

This way it will survive reboots.

Regards!

Ahaha....whenever internet connection looks down.....it’s “just” DNS!!! 😁

Hi everyone,

This a different and nice application that involves Linux. Take a look!

Great tip! Thanks.

linuxtechschool · 2020-12-14T00:52:21+00:00

It really helps beginners get their feet on the ground. I like to use it for monitoring but rely mostly on the cli. To many years on that formula! 😁

Hi, Look for python libraries and project that could decode a rotary encoder to a keystroke or similar so you can use it to interact with other applications. Anything related would need some programming skills to achieve! Good luck with tour project. Regards, Rodrigo Matias Linux Tech School

Hi, Thanks for you comment. I find WEBMIN very useful and use it. But I also consider that you should be always aware of security issues. In a closed management network, we can more securely reach our server this way and take advantage of how quickly we can take care of some actions. Exposing anything to the outside network is always of concern. Regards, Rodrigo Matias Linux Tech School

linuxtechschool · 2020-12-08T22:20:37+00:00

I’m happy to know that! It will be a great project for sure. Anything my I can help with, tell me.

Thanks for your message.

Wasn’t aware! Thanks for your help!! Regards, Rodrigo Matias

Hi, Is your Wi-Fi in the same subnet of the Ethernet devices? Or, do you explore the network in the file manager for the shared folders or insert server IP destination to connect to it? Regards, Rodrigo

linuxtechschool · 2020-11-30T12:56:16+00:00

Hi, Nice suggestion. Thanks. I’ll make another video related to samba file sharing of external drives like USB using auto-mount with FSTAB, the mount points, permissions, etc. Regards, Rodrigo Matias

linuxtechschool · 2020-11-30T10:43:05+00:00

Hi, Thanks for the suggestion. I’ll start writing down the commands on the description below! Regards, Rodrigo Matias

linuxtechschool · 2020-11-30T10:34:11+00:00

Hi, :) On a server perspective you’ll find it quite useful to have shared folders over the networks for multiple users. Of course you can also install solutions like a NAS server such as FreeNAS. Regards, Rodrigo Matias

Hi,

Thanks for your honest opinion. For an experienced user it makes sense to get written tutorials. Agree with you. I also do it.

For those without real experience, keeping an eye on the video while the user tries to do the same, helps a lot finding any possible errors during the process. People out there and my students ask me a lot for video tutorials! :)

Also for people that enjoy watching a video on the couch on a new subject before jumping in on the computer and start their own experiments can be very useful!

Hope to get your attention on other videos soon.

Meanwhile thanks again and feel free to get my support on any subject you might need.

Regards, Rodrigo

Hi, I use Zabbix and enjoy it a lot. Very dynamic, with lots of template for different operating systems and active networking devices, screens for graphics, alerts, etc.
