About NetSonar

NetSonar is a network diagnostics tool for pinging hosts (ICMP/TCP/UDP/HTTP), managing network interfaces, and discovering local devices/services.
Features multi-protocol latency checks, subnet scanning, port/service detection, and real-time interface configuration.
Designed for administrators and developers needing lightweight, cross-platform network analysis.

What's new in 0.6.0

- Add the Network Scanner module with local-network target discovery, host and port scanning, monitoring import,
cross-platform dependency installation, and a built-in ICMP sweep, neighbour-cache, and TCP-connect engine for systems
without nmap; configure engine selection, DNS resolution, service/version, UDP and OS detection, port presets and
custom ranges, timing, host/probe timeouts, host limits, and automatic rescans; show live progress, percentage and
ETA, searchable host/port/service results, per-host actions, scan-to-scan comparisons, persisted scan history,
JSON/CSV exports, and raw nmap reports
- Fix network-interface refresh reapplying unchanged filters and resetting cards, which caused scroll jumps, lost hover
state, and settings-button flicker
- Ask for acceptance of Ookla's EULA, terms of use, and privacy policy before the first speed test or server lookup,
skip automatic speed tests until accepted, and allow revoking the acceptance from the speed test settings
- Remember the selected speed test server between sessions
- Use an Ookla speedtest CLI installed on the system when no bundled copy is available, such as on Windows ARM64, and
show the missing-dependency panel when none is found instead of failing on start
- Translate the speed test results grid and refresh it when the language changes
- Fix speed tests failing on multi-gigabit connections that transfer more than 2 GB during a test
- Fix the speed test page freezing the UI while reading the speedtest version on first open
- Fix the Linux speed test auto-install installing the unrelated Python speedtest-cli; the Ookla CLI is now installed
manually on Linux
- Fix download and upload columns of the speed test results sorting as text instead of by bandwidth
- Fix the speed test gauge keeping the range of a faster result when selecting a slower one
- Fix the speed test results menu commands not reflecting the current selection, and disable them while a test runs
- Fix the update-check cross-thread exception
- Fix the consecutive succeeded/failed counts and the last succeeded/failed/executed times of the ping services being
computed from the oldest replies after restoring persisted replies on startup
- Fix ping scheduling blocking worker threads and stalling other services behind slow probes, which also inflated
measured response times, and keep the status counters and the status filter in sync with the latest replies …
