From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

My Ubuntu server (which has been working for a few years now) recently asked me in a full-screen prompt while updating something about GRUB. There was a list of partitions with just one element, which is the partition that GRUB os on. I was focused on something else so I just hit enter, but now I am really scared to reboot it. Is there any way to pull this back up or to double-check that everything is ok with the machine?

I've got one progam that I need for work that I cannot get to run on Linux. I've tried WINE on both Ubuntu and Zorin (and winlator for android). I have the installer exe file and try to launch with WINE but then nothing happens. Is that a program problem, WINE limitation, or something else? Is there a different program I should try to launch it?

Is plasma big screen really an option? Id like to install it on a desktop to act as a android tv. Launch Stremio, YT and maybe one or two other apps/websites. Easy big tile navigation with remote (flirc).

It's in dev since 2020. The images hosted on the site are bit for any of my hardware. It says theres a Debian package. Installed that though LMDE but it was horrible. Somone mentioned Kububtu can install it with apt, but its not listed. Think I'll give up.

I got one!

What constrains access to an rpc socket in the file system? Is it just the permissions of the socket or is there more to the whole process?

E: I originally wrote port instead of socket because it was early lol.

I have a server that has multiple services running under multiple users that each store data. I want to be able to bundle all this data up and send it to another server for backups.

At a high level, how do I manage permissions for this? Currently I run the backup as root, then chown it to a special backups user which can log in through ssh. But this all feels clunky to me.

There are many ways to do this, but the next up from users is using groups!

For each file or data directory, create a group that owns it. This group should have the service's user as member. Then create a user for running the backups, and add it to all these groups.

The benefit of this is you don't have to use root, and you have an association of directory to group that you can always change. You can for example grant a user access to a data directory by just adding it to its group.

Might want to take a look at a dedicated backup tool like Borg. It will keep all the proper permissions and file attributes in the backup.

Howdy. I have a "homeserver" that I'd like to actually start using. What's currently keeping me from it are... Permissions.
I have TrueNas Scale running on top of Proxmox, and I can't for the life of me not access NFS Shares from other VMs (specifically a Debian VM that I use as Docker Host) that I host in Proxmox. Plox hlp.

I want to upgrade (Mint 21.3 => 22). Last upgrade took hours and the result was so bad I had to reinstall Mint from scratch. Do you guys use the upgrade tool, or do you have good advice on how to approach this?
