Profitap 抓包工具 Profishark-100M
ProfiShark 100M是一款便攜式網路TAP設備，專為現場工程師設計，用於流量捕獲和故障排除。它通過USB 3.0供電，能夠捕獲高保真的網路流量，具備精確時間戳記，並支持Wireshark等網路分析工具。作為非侵入式設備，它不改變原始流量，確保網路安全性和性能。ProfiShark管理器提供數據包切片、統計和配置選項，進一步提升捕獲效率。
Description
ProfiShark以可擕式形式實現完整的數據捕獲。這意味著您可以在任何地方快速部署，並捕獲所需的流量數據，而不會影響生產網路。
To help optimize your analytical workflow and reduce disk storage consumption, ProfiShark offers packet slicing to ensure you get only actionable data.
Capture network data without compromising security or performance.ProfiShark and host PC will not appear as nodes on the network. The network connection will be maintained even if the ProfiShark's power is disconnected.ProfiShark is set to pass-through PoE.
Accurate timestamping is critical for analyzing performance metrics such as TCP, TCP stream throughput, latency and jitter, and the ProfiShark 100M provides hardware timestamping with 8ns accuracy.
Place ProfiShark in the row of packets to be analyzed and use the ProfiShark Manager GUI to control hardware and packet capture settings.
Captures all bytes from layer 1 to layer 7 with high quality timestamps regardless of packet rate.
Start capturing to tiles directly without external software, instant capture in Wireshark, long term traffic capture on NAS.
ProfiShark is supported on all major operating system options on the market today: Linux, Windows and macOS.
All ProfiShark models can be configured in inline mode or out-of-band to monitor traffic from SPAN/mirror ports or external TAPs.The ProfiShark 100M has a passive connection to the network via PoE pass-through. By design, this makes it fail-safe.
ProfiShark is typically used in conjunction with Wireshark for protocol analysis, but can be used in conjunction with most traffic analyzers.
The monitored network is physically isolated (diode) from the host to avoid any risk of injection or MITM attacks through the device.
ProfiShark can be powered via USB 3 port or 5V DC input.
長期流量捕獲
ProfiShark長期捕獲解決方案在設計時考慮了靈活性。長期捕獲功能與可根據您的特定需求量身定制的NAS相結合，可以輕鬆地捕獲行為中的間歇性問題。
優點：
(1) Ringbuffer或正常擷取模式，根據擷取時間或檔案大小，將側錄封包拆分為不同的PCAP檔案。
(2) 兼容所有使用Intel晶片的Synology NAS系統，並與DSM系統相容。
(3) 支援Ingress Time-Stamping 時間戳記，可再TSN網路擔任延遲量測的封包擷取工作。
(4) Packet Slicing與封包過濾擷取等。(ProfiShark 10G)
(5) 可偵測並接收會被一般網卡丟棄的CRC封包，可以顯示CRC error等網路介面的硬體問題。
(6) 利用Synology雲端空間同步功能，實現從遠端抓取本地端pcap檔的功能，資料分析人員不須來回奔波。

簡易設置文件保存、緩衝區大小及循環錄製功能，適合高效數據捕捉需求。
封包擷取模式
ProfiShark擷取封包模式，可為Local或Direct Capture兩種
– Live capture：使用Wireshark(或其他支援軟體)，把ProfiShark當作USB網卡，擷取封包在軟體即時顯示。
– Direct Capture：使用專屬ProfiShark Manager，可將資料用更快速度，直接寫入硬碟。
Direct Capture設定
設定PCAP分檔的條件，使用檔案大小，或側錄時間。
