Packet Capture Analysis Guides

PCAPNG Analyzer vs Wireshark: an honest comparison

See where Wireshark is clearly stronger, where a self-hosted report helps, and why the most effective workflow often uses both.

Validate capture quality, establish scope, rank traffic and turn broad symptoms into testable packet-level questions.

Separate real retransmissions from capture artefacts, identify the affected flow, and reason about loss, congestion and delay.

Pair queries with responses, measure response time, find slow names and distinguish DNS delay from application delay.

Find RST packets, identify which endpoint sent them, and use sequence and timing context to explain why.

Use command-line summaries, split targeted subsets, or process the capture in a self-hosted web interface.

Find clear-text requests and responses, isolate streams, export useful fields, and understand the limits imposed by HTTPS.

Choose a capture format based on interfaces, metadata, timestamp resolution and tool compatibility.

Use TCP sequence analysis, duplicate acknowledgements and retransmissions without confusing missing capture data for network loss.

Review visible handshakes, names, versions, cipher suites and certificates without overstating what encrypted traffic reveals.

Rank endpoints and conversations by packets, bytes and direction, then account for duration and capture-point bias.

Collect a fair pair, normalise unequal durations and validate meaningful protocol, endpoint and application deltas.

Configure a Docker bind mount, use a safe file handoff, and manage the storage and capacity implications of auto-ingest.
