• Python, XML, Unix/Linux commands
• Problem-solving and automation

Features

• XML Parsing: Reads device info from XML.
• Ping Checks: Verifies if devices are online or offline.
• CLI & Web Interface: Offers both command-line and web-based access (via Flask).
• Multi-threaded: Efficiently pings multiple devices in parallel.
