LINUX NETWORKING TOOLS

NETWORKING FUNDAMENTALS

COMPONENTS OF DOCKER EXPLAINED (Simplified) Docker is a containerization platform that packages apps so they run consistently across environments. Its core components are: 1. Docker Images Read-only blueprints used to create containers. They include the app, runtime, libraries, dependencies, and configs. Images are typically stored and shared via registries like Docker Hub. 2. Docker Containers A running instance of an image. Containers are lightweight, isolated, and portable environments that ensure applications behave consistently anywhere they run. 3. Dockerfile A script that defines how an image is built. It specifies the base image, dependencies, environment variables, and build/run commands. 4. Docker Daemon (dockerd) The background service that manages containers, images, networks, and volumes. It processes all Docker API requests. 5. Docker Engine The full runtime system consisting of the daemon, REST API, and CLI. It’s what lets you build, run, and manage containers. 6. Docker Volumes Persistent storage for containers. They keep data intact even if containers are stopped or deleted and can be shared across containers. How it all fits together: A Dockerfile builds an Image → an Image runs as a Container → the Docker Engine + Daemon manage everything → Volumes ensure data persistence.

@Hamzaonchain Ebay

How can I get this? 😂

@Hamzaonchain The answer is C When the file (usually an executable) is run, the process runs with the privileges of the file owner, regardless of who executes it. A common example is the sudo command so normal users can perform privileged tasks safely.

@vxunderground 😆not bad actually, maybe some ads

My goofy ass website gets 142,000+- unique visitors a month. Dawg, I have GOT to find a way to monetize this without dropping to my knees and begging like a dirty scoundrel on the internet. I've worked on this gunkie slermie everyday for 7 years. I gotta do something

@5mukx @github @Microsoft @MsftSecIntel 💔

Dear @github @Microsoft and @MsftSecIntel . Thank you for your service. I have lost all hopes from you guys. As a Windows security researcher whose intent was to help the beginners and contribute to open source security tooling, and i had so much respect towards @Microsoft , that thought was changed today and i am leaving. I have left the enough evidence in the ticket session. I would be better if a security researcher from GitHub might actually take a look at these. Thank you and bye to the community..... Here after you will not see posts about GitHub issues. Ticket ID: #4440743 #github #msft #defense #unlawful

@CyberRacheal you left it opened

Interviewer: You use private browsing mode on a public computer. Why can the next user still see your search history?🤔

fun fact: my first contribution was to the microsoft repository. You can see how much respect i had to them. Now I'm just loosing hope = ( . I hope @github @MsftSecIntel @Microsoft will bring my hope back. Lets see.

@5mukx @vxunderground This is ridiculous. flagged for “malware” even though he was sharing public, legal PoC security tools and research. It's discouraging that many years of research has gone down the drain over an allegation. @github @Microsoft @MsftSecIntel

I request the community to share this issue and help me resolve it. This is a major concern: sharing legal, open-source, public proof-of-concepts is now considered illegal? Is helping the open-source security community now against the terms of service? Or is this the new normal?! 2026 is causing a lot of trouble for security researchers. I'm trying my best to follow the ToS, rules, and regulations of @github, @MsftSecIntel, and @Microsoft, but I'm starting to lose hope in conducting research, submitting vulnerabilities now.. Really i saw this on today morning and i am very disappointed. I have an little hope @github @MsftSecIntel @Microsoft.

Honestly, what is this ? I got a response from @github support team. So here after legal Security Research and PoC's is not allowed on GitHub ? I'm Completely got disappointment by @github and @Microsoft @MsftSecIntel . In what ways i distribute and share malware. Can anyone tell me if there is a mistake from my side, did i share 0 days, vulnerabilities, direct binaries or full exploit chain that harm users ? NONE ? is posting Legal source codes and tools that are made of public PoCs are wrong ? there are thousand of full chain real expoits that bypasses EDRs, C2s that evades security solutions, phishing kits that bypasses MFA of Microsoft out there in @github , if that is legal then why cant this simple publically made poc can't be in the github ? I have replied regarding my statements, please don't disappoint younger legal windows security researchers like this. I have some little hope on @github @Microsoft @MsftSecIntel . I have a little hope. So Please don't make me loose on @github & @Microsoft & @MsftSecIntel . Ticket ID: #4440743 Will be waiting for your kind response. Thank you. x.com/5mukx/status/2… #github #microsoft #security #research
