Click or drag files to this area to upload
Upload .pcap files for online analysis. The online version currently only supports analyzing files up to 50MB.
Features & Guide
File Processing Information
Files need to be uploaded to the server for parsing, and the parsing results are returned to the page through SSE for display. Files are temporarily stored on the server disk.
Files are not permanently stored and will automatically expire after 7 days. You can also manually delete them after analysis is complete.
File Size Limitations
We limit the web version to analyze files up to 50MB maximum, because large files take time to parse, and the SSE transmission process back to the frontend is also affected by network conditions, requiring too long a wait time. Very large files may not provide a good user experience.
For very large files, we recommend downloading the APP for offline analysis.
Login Requirement
To isolate each user's files, you need to log in to upload pcap files for analysis.
Why store your files?
Because analysis may not be one-time, you may need to review it repeatedly. Also, after analysis, you may still need it when writing summaries, which avoids multiple uploads.
TCP/UDP Separation
When you click View TCP, if there are UDP packets in the pcap file, you won't see UDP packets and need to go back and click View UDP.
This is because TCP and UDP concepts are too different and not suitable to be mixed together, which affects our goal of keeping the product simple and easy to use.
Generally, when analyzing a problem, we don't encounter situations where TCP and UDP need to be analyzed together. This is also why the App is split into two apps.
TCP Analysis Protocol Support
Supported application layer protocols: HTTP, WebSocket, Redis, MySQL.
ChatTCP does not support decoding SSL/TLS, such as HTTPS, WSS.
Future versions will support user-defined protocol decoding through script plugins.
UDP Analysis Protocol Support
Supported application layer protocols: DNS.
More protocols will be supported in the future.
Text Protocol Support
If the application layer protocol is not a binary protocol, but a plain text protocol like HTTP, it can also be analyzed with ChatTCP.
For example, SMTP, JSON-RPC protocols, etc.
Case Library
You can also view some cases provided in our case library. These cases can meet the needs of beginners for protocol learning and help familiarize themselves with ChatTCP features.
