Network & System Tools
Open-source tools for network discovery, diagnostics, and Windows infrastructure inventory.
Why this collectionTraditional administration and diagnostic tools are excellent at answering the question “What?”: which services are running, which IP addresses are configured, which ports are open, and what differences exist between two systems. Over the years, it became clear that administrators and technicians often needed to go further. When a problem occurs, the important questions quickly become:
o Why is this happening?
o What are the probable causes?
o What should be done to fix the problem?
The NetDTL collection was born from this idea. It does not merely inventory or observe systems: it tries to understand the relationships between collected information, explain possible causes of failures, and suggest concrete courses of action. In other words: after the “What?” come the “Why?” and the “What should we do?”.
