Posted by Fedora Magazine on 2024-07-26 08:00:00 UTC

Fedora test days are events where anyone can help make certain that changes in Fedora work well in an upcoming release. Fedora community members often participate, and the public is welcome at these events. If you’ve never contributed to Fedora before, this is a perfect way to get started.

There are two upcoming test periods in the next week covering two topics:

  • Sunday 28 July through Sunday 04 August, is to test Kernel 6.10.
  • Monday 29 July through Wed 31 July , is to test Podman 5.2

Come and test with us to make Fedora 41 even better. Read more below on how to do it.

Kernel 6.10 Test Week

The kernel team is working on final integration for Linux kernel 6.10. This recently released kernel version will be the release Kernel for Fedora 41. As a result, the Fedora Linux kernel and QA teams have organized a test week from Sunday, July 28, 2024 to Sunday, August 04, 2024.

The wiki page contains links to the test images you’ll need to participate. The results can be submitted in the test day app.

Podman 5.2 Test Days

Podman is a daemon-less, open source, Linux native tool designed to make it easy to find, run, build, share and deploy applications using Open Containers Initiative (OCIContainers and Container Images. It provides a command line interface (CLI) familiar to anyone who has used the Docker Container Engine. As part of a recent discussion, the Rawhide Test Day efforts, and Podman Container Engine Team’s collaborative efforts, we will hold test days for this minor Podman Release.

During these test days, on Monday 29 July through Wed 31 July, the focus will be on testing the changes that will be coming in Fedora 41 (Rawhide) as we move ahead with Podman 5.1. This is an opportunity for anyone to learn and interact with the Podman Community and container tools in general.

The wiki page helps the testers know and understand the scope of the test days. The Test day app helps the testers submit the results once they have tried the test cases.

How do test days work?

A test day/week is an event where anyone can help make sure changes in Fedora Linux work well in an upcoming release. Fedora community members often participate, and the public is welcome at these events. If you’ve never contributed before, this is a perfect way to get started.

To contribute, you only need to be able to download test materials (which include some large files) and then read and follow directions step by step.

Detailed information about all the test days is available on the wiki pages mentioned above. If you’re available on or around the days of the events, please do some testing and report your results. All the test day pages receive some final touches which complete about 24 hrs before the test day begins. We urge you to be patient about resources that are, in most cases, uploaded hours before the test day starts.

A veneer of organization

Posted by Ben Cotton on 2024-07-24 12:00:00 UTC

When all you have is a hammer, everything looks like a nail. In much the same way, when your background is in organization, everything looks like a process need. While open source projects do need process and organization (otherwise I wouldn’t have written a book!), the amount of process needed grows with the size of the community.

Too often, I’ve seen (including from myself) community leaders build out way more process than is necessary. This isn’t necessarily harmful, but it does distract from getting more meaningful work done. It’s a way to look busy without accomplishing anything. Process can be the scaffolding to build and grow community, but if you have scaffolding you’ll never use, it was a waste to set it up.

I’ve recently found myself tempted to re-organize some of the governance documentation for GUAC. Not improving or streamlining processes, just shuffling it into a different place. But while I have no doubt that I am right in my opinion, the current state is sufficient. I could put the work in to reorganize the content and convince the maintainers to approve my pull requests. That seems like a waste of everyone’s time, when I could instead be trying to recruit new contributors, write blog posts, find reference users, and generally just do the hard work that pays off.

In a previous role, my manager and I were working on a corporate style guide for the marketing team to use. I asked her “should I put this in Jira or would that just be a coat of paint?” In other words: would the effort to set up a board to track the work be worth the coordination benefit we’d get?

Finding the right level of organization

There are a few things you need to have right away. You need a:

Once you have those things, get building! Wait to solve problems until you have them. You can’t know for sure which problems you’ll have first anyway. Communities are not code: you don’t have to anticipate every possible exception.

People will typically follow processes that they 1. know about and 2. understand. So if you can’t make the case for why the process is necessary right now, you probably don’t need it. In Program Management for Open Source Projects, I wrote about looking for the places people cut corners on a process to figure out where you need to improve it. Improvement can also be “remove the process.” If you discover you’ve been over-enthusiastic about process creation, it’s not to late to take a step back.

One guideline I like to use to check myself: whose life does this make easier? If the answer is only “mine!”, then it’s probably not worth imposing on the rest of the community.

Finding the right level of organization is a trial-and-error process. Even if you’ve done it before, no two communities are exactly alike. And, if you’re lucky, once you’ve found the right level, the community will grow and you’ll have to adjust again.

Introduction to my Dotfiles

Posted by Tristan Partin on 2024-07-24 05:07:44 UTC

Over time, I’ve accrued a fair amount of dotfiles. I thought I would share an overview of them through a series of blog posts, starting now!

Posted by Mohammadreza Hendiani on 2024-07-23 20:00:49 UTC

The AI industry is going to the way of desktop:
- First there was the Linux kernel, and the GNU toolkit.
- Then came the DE and its basic tools.
- And now there's a whole bunch of tools with decent compatibility with each other. + extensions + third party add-ons .....

But I still can't believe that was the first one to drop the monolithical design of put everything in the model.

Why it is useful to set the version number in the syslog-ng configuration

Posted by Peter Czanik on 2024-07-23 13:52:15 UTC

The syslog-ng configuration starts with a version number declaration. Up until recently, if it was missing, syslog-ng did not start. With syslog-ng 4.8, this is changing.

From this blog, you can learn why version information is useful, what workaround you can use if you do not want to edit your syslog-ng configuration on each update, and what changed in version 4.8.

Lithium-ion (Li-ion) batteries are known for their high capacity and long life, while nickel-metal hydride (NiMH) batteries are a popular choice for rechargeable options. Ensure that your flashlight supports the type of rechargeable battery you choose. Rechargeable batteries often come with built-in charging circuits, which can be convenient.
  • CR123A Batteries: CR123A batteries are often used in high-performance flashlights due to their long battery life and high output. They are more expensive than alkaline batteries but offer excellent performance in terms of brightness and runtime.

Battery Tips:

  • Check Battery Life: Review the flashlight’s runtime specifications to ensure it meets your needs. Consider how long the flashlight operates on a single charge or set of batteries and whether it aligns with your usage patterns.
  • Evaluate Charging Options: Some flashlights feature built-in USB charging capabilities, which can be very convenient. Evaluate the charging options available and choose a flashlight that suits your preferences.
  • Spare Batteries: For critical situations or extended use, having spare batteries on hand is essential. Consider investing in additional batteries to ensure that you are never left in the dark.

4. Build Quality and Features

The build quality and features of a flashlight can greatly influence its usability, durability, and performance. Here are some factors to consider:

  • Material: Flashlights are typically made from materials like aluminum, stainless steel, or plastic. Durable materials like aluminum or stainless steel offer better resistance to impact and environmental conditions, making them suitable for rugged use. Plastic flashlights may be lighter but can be less durable.
  • Water Resistance: If you plan to use your flashlight in wet conditions, check the IPX rating. The IPX rating indicates the level of water resistance:
  • IPX4: Splash-resistant from any direction.
  • IPX7: Can be submerged in up to 1 meter of water for 30 minutes.
  • IPX8: Can withstand continuous immersion in water beyond 1 meter. Ideal for underwater use.
  • Impact Resistance: Look for flashlights with high impact resistance if you’ll be using them in rough environments. Flashlights designed to withstand drops and impacts are better suited for outdoor adventures or professional use.
  • Size and Weight: Balance the flashlight’s size and weight against your needs. EDC flashlights are usually compact and lightweight, while tactical or professional models may be larger and heavier. Consider how the size and weight will affect portability and ease of use.

5. Additional Features

Many flashlights come with additional features that can enhance their functionality. Consider the following features based on your specific needs:

  • Modes: Flashlights with multiple brightness modes (low, medium, high) offer versatility for different tasks. Some models also include special modes like strobe, SOS, or beacon. These modes can be useful for signaling or emergency situations.
  • Focus Adjustment: Adjustable beam focus allows you to switch between a wide floodlight and a narrow spotlight. This feature is beneficial for tasks that require different lighting patterns, such as reading up close or illuminating a distant area.
  • Holsters and Mounts: For tactical or professional use, accessories like holsters, mounts, or clips can add convenience. Holsters keep the flashlight easily accessible, while mounts allow for hands-free operation.
  • Durability Features: Some flashlights come with additional durability features, such as anti-roll designs, ergonomic grips, or heat dissipation mechanisms. These features can enhance the overall usability and performance of the flashlight.

6. Budget Considerations

Understanding Permission Setting and Security on FreeBSD vs. Linux

Posted by Piju 9M2PJU on 2024-07-22 14:09:36 UTC

Introduction

When managing Unix-like operating systems, understanding permission settings and security practices is crucial for maintaining system integrity and protecting data. FreeBSD and Linux, two popular Unix-like systems, offer distinct approaches to permission settings and security. This article delves into these differences, providing a comprehensive comparison to help system administrators and users navigate these systems effectively.

1. Overview of FreeBSD and Linux

FreeBSD is a Unix-like operating system derived from the Berkeley Software Distribution (BSD), renowned for its stability, performance, and advanced networking features. It is widely used in servers, network appliances, and embedded systems.

Linux, on the other hand, is a free and open-source operating system kernel created by Linus Torvalds. It is the foundation of numerous distributions (distros) like Ubuntu, Fedora, and CentOS. Linux is known for its flexibility, broad hardware support, and extensive community-driven development.

2. File System Hierarchy

Both FreeBSD and Linux follow the Unix file system hierarchy but with slight variations. Understanding these differences is key to grasping permission settings on each system.

  • FreeBSD: Uses the Filesystem Hierarchy Standard (FHS) but has its nuances. The /usr directory contains user programs and data, while /var holds variable data like logs and databases. FreeBSD also utilizes /usr/local for locally installed software.
  • Linux: Generally adheres to the FHS. Important directories include /bin for essential binaries, /etc for configuration files, /home for user directories, and /var for variable files.

3. Permissions and Ownership

Both systems use a similar model for file permissions but have some differences in implementation and additional features.

3.1 Basic File Permissions

  • FreeBSD:
  • Owner: The user who owns the file.
  • Group: A group of users with shared permissions.
  • Others: All other users.
  • Permissions are represented as read (r), write (w), and execute (x) for each category. Commands to manage permissions:
  • ls -l: Lists files with permissions.
  • chmod: Changes file permissions.
  • chown: Changes file ownership.
  • chgrp: Changes group ownership.
  • Linux:
  • Similar to FreeBSD, Linux file permissions are also divided into owner, group, and others.
  • Commands are the same: ls -l, chmod, chown, chgrp.

3.2 Special Permissions

  • FreeBSD:
  • Setuid: Allows users to execute a file with the file owner’s permissions.
  • Setgid: When applied to a directory, new files inherit the directory’s group.
  • Sticky Bit: Ensures only the file owner can delete the file.
  • Linux:
  • Setuid: Allows a user to execute a file with the permissions of the file owner.
  • Setgid: When set on a directory, files created within inherit the directory’s group.
  • Sticky Bit: Similar to FreeBSD, it restricts file deletion.

4. Extended Attributes and ACLs

4.1 FreeBSD:

FreeBSD supports Extended File Attributes (EAs) and Access Control Lists (ACLs) to provide more granular permission control.

  • Extended Attributes: Used to store metadata beyond standard attributes. Managed with setfattr and getfattr.
  • Access Control Lists (ACLs): Allow setting permissions for multiple users and groups. Managed with setfacl and getfacl.

4.2 Linux:

Linux also supports Extended Attributes and ACLs.

  • Extended Attributes: Managed with setxattr and getxattr.
  • Access Control Lists (ACLs): Managed with setfacl and getfacl.

5. Security Models and Practices

5.1 FreeBSD Security Model:

FreeBSD includes several features for enhanced security:

  • Jails: Provide a form of operating system-level virtualization. Each jail has its own filesystem, network configuration, and process space, which helps in isolating applications and services.
  • TrustedBSD Extensions: Enhance FreeBSD’s security by adding Mandatory Access Control (MAC) frameworks, which include fine-grained policies for file and process management.
  • Capsicum: A lightweight, capability-based security framework that allows developers to restrict the capabilities of running processes, minimizing the impact of potential vulnerabilities.

5.2 Linux Security Model:

Linux employs a range of security modules and practices:

  • SELinux (Security-Enhanced Linux): A set of kernel-level security enhancements that provide mandatory access controls. It defines policies that restrict how processes can interact with files and other processes.
  • AppArmor: A security module that restricts programs’ capabilities with per-program profiles. Unlike SELinux, it uses path-based policies.
  • Namespaces and cgroups: Used for containerization, allowing process isolation and resource control. These are the basis for technologies like Docker and Kubernetes.

6. System Configuration and Management

6.1 FreeBSD Configuration:

FreeBSD uses configuration files located in /etc and other directories for system management. The rc.conf file is central for system startup and service configuration. The sysctl command is used for kernel parameter adjustments.

6.2 Linux Configuration:

Linux configurations are distributed across various directories like /etc for system-wide settings and /proc for kernel parameters. Systemd is the most common init system, managing services and their dependencies. The sysctl command is also used in Linux for kernel parameter adjustments.

7. User Management

7.1 FreeBSD:

FreeBSD manages users and groups through /etc/passwd, /etc/group, and /etc/master.passwd. User and group management commands include adduser, pw, and groupadd.

7.2 Linux:

Linux also uses /etc/passwd and /etc/group for user management. User and group management commands include useradd, usermod, groupadd, and passwd.

8. Network Security

8.1 FreeBSD:

FreeBSD offers robust network security features, including:

  • IPFW: A firewall and packet filtering system integrated into the kernel.
  • PF (Packet Filter): A powerful and flexible packet filter that provides firewall functionality and network address translation (NAT).

8.2 Linux:

Linux provides several options for network security:

  • iptables: The traditional firewall utility for configuring packet filtering rules.
  • nftables: The successor to iptables, offering a more streamlined and flexible approach to packet filtering and NAT.
  • firewalld: A front-end for iptables and nftables, providing dynamic firewall management.

9. Backup and Recovery

9.1 FreeBSD:

FreeBSD supports several backup and recovery tools:

  • dump/restore: Traditional utilities for file system backups.
  • rsync: For incremental backups and synchronization.
  • zfs snapshots: ZFS filesystem features allow creating snapshots for backup and recovery.

9.2 Linux:

Linux offers a range of backup and recovery tools:

  • tar: A traditional tool for archiving files.
  • rsync: For incremental backups and synchronization.
  • LVM snapshots: Logical Volume Manager features provide snapshot capabilities.

10. Conclusion

Both FreeBSD and Linux offer robust permission settings and security features, each with its strengths and specific implementations. FreeBSD provides a comprehensive suite of security features, including jails and Capsicum, while Linux offers a variety of security modules like SELinux and AppArmor. Understanding these differences is crucial for system administrators to effectively manage and secure their systems. By leveraging the unique features of each operating system, administrators can enhance their systems’ security and maintain a robust and reliable computing environment.

Fedora Infra musings for the third week of july

Posted by Kevin Fenzi on 2024-07-20 16:56:09 UTC

Another week has raced by (time flies when you’re having fun?). flock to fedora is coming up really fast now. It’s Aug 7th to 10th in Rochester, NY. Looking forward to meeting up with everyone there and having some great discussions. I have a talk (which I still need to write up) on matrix, which should be fun and then a Infrastructure and Release Engineering hackfest which I need to work on organizing a bit more. Look for more info on discussion.

On monday I managed to get updated firmware for our aarch64 emag’s. Got them all updated, reinstalled and re-added as builders just barely in time for the mass rebuild. This sort of thing takes a really tremendous amount of time. I’d like to explain for those that haven’t had this sort of fun before. There’s a lot of parts of this process where you need to wait for something to happen and do something in reaction to it. ie, wait for one firmware (there’s 3 on these aarch64 machines) to finish updating, then reload and upload the next one. For some reason I couldn’t force them to pxe boot in all cases, so that meant: login to serial console, watch the server boot, when it gets to a specific point hit esc-shift-1 to pxe boot. If you miss it, you have to start over. You might think you could do other things while this is happening, but… when you do, you always miss the window to hit the key and have to keep doing it over and over. Next fun with these was that they have 4 interfaces and for some unknown reason, they are all active on various vlans and which one gets the ‘default’ route is somewhat random. If it’s not the actual builder network, it can’t reach resources and fails the install. Some times one or more of the interfaces wouldn’t come up with a cryptic error. If this was the main network, you had to reboot and try again. Once they were pxe booted the kickstart install and ansiblizing was easy. Hopefully they will work on now until we retire them.

Our resultsdb app’s pods have been restarting. It’s not super clear as to the cause. They hit max threads and the health check fails and then they restart, but the reason for the max threads isn’t clear. Is it somehow getting blocked on database writes so requests pile up? Or is it just getting too many requests at once to handle properly. I looked at it some, but the resultdb image that we use is made by the factory2 team (which no longer exists), and it’s not very easy to enable debugging in. Will look at it more next week.

Overall this week I didn’t feel like I got much done. Too many things that are difficult/require a lot of time and it’s hard to feel progress on them. Hopefully next week will go better!
