Exportul și analiza adreselor IP libere din DHCP Server

Când administrezi o rețea de companie și trebuie să configurezi echipamente noi cu IP static (imprimante, servere, camere de supraveghere sau AP-uri), ai nevoie să știi rapid ce IP-uri sunt libere într-un anumit subnet.

Navigarea manuală prin consola grafică DHCP (clic pe Address Leases, sortare, căutare vizuală a golurilor) este obositoare și predispusă la greșeli. Acest script de PowerShell interoghează direct rolul de DHCP și îți returnează instant o listă curată cu primele IP-uri disponibile.

Ce face această soluție?

  1. Interoghează un anumit Scope (subnet) configurat pe serverul DHCP local sau de la distanță.

  2. Identifică adresele IP care nu sunt alocate (nu au lease activ și nu sunt în rezervări).

  3. Afișează instant primele 20 de adrese IP sigure pentru a fi folosite.

How to use Ollama and Open WebUI with Docker Compose

Before you start running some Docker Compose commands, be informed of some of the software that needs to be running on your machine:

  1. You will need Docker running on your machine, for this example, I am using Docker 27.4.0 on Mac
  2. Make sure you have Docker Compose available as well (it used to be a different install when it was docker-compose in v1; from v2, it is coupled with the Docker Desktop installation). I am using Docker Compose version v2.31.0-desktop.2 on a Mac)
  3. It would be good to know about Docker volumes, docker ports, and basic docker commands

I reclaimed the Windows Start menu by turning off these 5 features

Microsoft keeps stuffing new features into the Windows 11 Start menu, and with most of them enabled by default, it has become unnecessarily cluttered. Add web search results that have zero value—when I need to search the web, I’ll just open a browser—and you end up with a Start menu that feels bloated rather than helpful. By disabling the following features and options, I turned the Start menu on my Windows 11 PC into a lightweight application launcher and local search interface.

Windows 11 screen turns off even when set to Never

Windows lets you decide how long your display should remain on before it automatically turns off during periods of inactivity. Many users set this option to Never to keep the screen active while monitoring downloads, security cameras, dashboards, presentations, or other ongoing tasks. However, some users have reported that their screens continue to turn off even when the setting is set to Never. In some cases, the display dims or goes black after a few minutes of inactivity.

To fix your Windows 11 screen if it turns off even when set to Never, use these solutions:

  1. Review Advanced Power Settings
  2. Disable the Screen Saver
  3. Turn off Presence Sensing
  4. Check other power plans for conflicting display timeout settings.
