Hi!


I have seen many ways to manage services in Ubuntu. Such as Systemctl - sysctl - systemd - /etc/init.d scripts and so on.


Some of them seem to work always, whereas some not.


�What is the difference among them all?


Thanks!

I have a problem with external display connected to my laptop. It displays "no-signal" warning.

I use DELL G15 5520-6600 laptop with Dell P2419H display. I use XFCE.

Below is my GPU info
Code: jan@jan:~$ lspci | grep VGA
0000:00:02.0 VGA compatible controller: Intel Corporation Alder Lake-P Integrated Graphics Controller (rev 0c)
0000:01:00.0 VGA compatible controller: NVIDIA Corporation GA107BM [GeForce RTX 3050 Mobile] (rev a1) nvidia-detect has suggested me to install nvidia-driver, but I got problems (after installation)
Code: jan@jan:~$ nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running I think my GPU supports optimus, but I'm not entirely sure. I have a problem with this site: https://www.nvidia.com/en-us/geforce...upported-gpus/
I tried to install bumblebee like that.

OS is Ubuntu 22.0 LTS.
Asus Z87 Plus Motherboard for 4th gen (2013) Core CPUs; features UEFI-Bios.
32 GB RAM.

This happened quite recently. The SATA hard drive is connected to USB adapter utilizing hotplug.

Even after unmounting the drive, it requires I physically unplug the USB cable from the motherboard, to get the mouse cursor to behave normally.

Microsoft's Windows Subsystem for Linux (WSL) continues to evolve with the release of WSL 2 version 0.0.2. This update introduces a set of opt-in preview features designed to enhance performance and compatibility.

Key additions include "Automatic memory reclaim" which dynamically optimizes WSL's memory footprint, and "Sparse VHD" to shrink the size of the virtual hard disk file. These improvements aim to streamline resource usage.

Additionally, a new "mirrored networking mode" brings expanded networking capabilities like IPv6 and multicast support. Microsoft claims this will improve VPN and LAN connectivity from both the Windows host and Linux guest. 

Complementing this is a new "DNS Tunneling" feature that changes how DNS queries are resolved to avoid compatibility issues with certain network setups. According to Microsoft, this should reduce problems connecting to the internet or local network resources within WSL.

Advanced firewall configuration options are also now available through Hyper-V integration. The new "autoProxy" feature ensures WSL seamlessly utilizes the Windows system proxy configuration.

Microsoft states these features are currently rolling out to Windows Insiders running Windows 11 22H2 Build 22621.2359 or later. They remain opt-in previews to allow testing before final integration into WSL.

By expanding WSL 2 with compelling new capabilities in areas like resource efficiency, networking, and security, Microsoft aims to make Linux on Windows more performant and compatible. This evolutionary approach based on user feedback highlights Microsoft's commitment to WSL as a key part of the Windows ecosystem.

The threat actor Earth Lusca, linked to Chinese state-sponsored hacking groups, has been observed utilizing a new Linux backdoor dubbed SprySOCKS to target government organizations globally. 

As initially reported in January 2022 by Trend Micro, Earth Lusca has been active since at least 2021 conducting cyber espionage campaigns against public and private sector targets in Asia, Australia, Europe, and North America. Their tactics include spear-phishing and watering hole attacks to gain initial access. Some of Earth Lusca's activities overlap with another Chinese threat cluster known as RedHotel.

In new research, Trend Micro reveals Earth Lusca remains highly active, even expanding operations in the first half of 2023. Primary victims are government departments focused on foreign affairs, technology, and telecommunications. Attacks concentrate in Southeast Asia, Central Asia, and the Balkans regions. 

After breaching internet-facing systems by exploiting flaws in Fortinet, GitLab, Microsoft Exchange, Telerik UI, and Zimbra software, Earth Lusca uses web shells and Cobalt Strike to move laterally. Their goal is exfiltrating documents and credentials, while also installing additional backdoors like ShadowPad and Winnti for long-term spying.

The Command and Control server delivering Cobalt Strike was also found hosting SprySOCKS - an advanced backdoor not previously publicly reported. With roots in the Windows malware Trochilus, SprySOCKS contains reconnaissance, remote shell, proxy, and file operation capabilities. It communicates over TCP mimicking patterns used by a Windows trojan called RedLeaves, itself built on Trochilus.

At least two SprySOCKS versions have been identified, indicating ongoing development. This novel Linux backdoor deployed by Earth Lusca highlights the increasing sophistication of Chinese state-sponsored threats. Robust patching, access controls, monitoring for unusual activities, and other proactive defenses remain essential to counter this advanced malware.

The Trend Micro researchers emphasize that organizations must minimize attack surfaces, regularly update systems, and ensure robust security hygiene to interrupt the tactics, techniques, and procedures of relentless threat groups like Earth Lusca.

The Linux kernel is undergoing major changes that will shape its future development and adoption, according to Jonathan Corbet, Linux kernel developer and executive editor of Linux Weekly News. Speaking at the Open Source Summit Europe, Corbet provided an update on the latest Linux kernel developments and a glimpse of what's to come.

A major change on the horizon is a reduction in long-term support (LTS) for kernel versions from six years to just two years. Corbet explained that maintaining old kernel branches indefinitely is unsustainable and most users have migrated to newer versions, so there's little point in continuing six years of support. While some may grumble about shortened support lifecycles, the reality is that constantly backporting fixes to ancient kernels strains maintainers.

This maintainer burnout poses a serious threat, as Corbet highlighted. Maintaining Linux is largely a volunteer effort, with only about 200 of the 2,000+ developers paid for their contributions. The endless demands on maintainers' time from fuzz testing, fixing minor bugs, and reviewing contributions takes a toll. Prominent maintainers have warned they need help to avoid collapse. Companies relying on Linux must realize giving back financially is in their interest to sustain this vital ecosystem. 

The Linux kernel is also wading into waters new with the introduction of Rust code. While Rust solves many problems, it also introduces new complexities around language integration, evolving standards, and maintainer expertise. Corbet believes Rust will pass the point of no return when core features depend on it, which may occur soon with additions like Apple M1 GPU drivers. Despite skepticism in some corners, Rust's benefits likely outweigh any transition costs.

On the distro front, Red Hat's decision to restrict RHEL cloning sparked community backlash. While business considerations were at play, Corbet noted technical factors too. Using older kernels with backported fixes, as RHEL does, risks creating divergent, vendor-specific branches. The Android model of tracking mainline kernel dev more closely has shown security benefits. Ultimately, Linux works best when aligned with the broader community.

In closing, Corbet recalled the saying "Linux is free like a puppy is free." Using open source seems easy at first, but sustaining it long-term requires significant care and feeding. As Linux is incorporated into more critical systems, that maintenance becomes ever more crucial. The kernel changes ahead are aimed at keeping Linux healthy and vibrant for the next generation of users, businesses, and developers.

Anytime I switch networks, when I open a file dialog to open a file or save, whatever application I'm using locks up indefinitely. I believe it is caused by the file dialog/window not being able to open the mount point that no longer exists.

Even if I umount /directory the file dialog still thinks it's there because it's in memory from the last time I opened it.

I can only surmise that this is a hardcoded bug and I'm wondering how to submit this for review. I suppose it's possible there is some switch or setting inside the kernel that addresses this problem?

Ok, so I try 'sudo umount /directory' the terminal locks up. CTRL+C doesn't force quit, and return sends the cursor to a new line.
