Yes - I mean arbitrary comma, tab and space separated. IIS web logs are in Space Separated Variable format (standard W3 format I believe). > And is there any reason not to just take the log file reading part of your > code, make it into a libwiretap module that *directly* reads those files > using a WTAP_ENCAP_IIS_LOG encapsulation, and write a dissector for > WTAP_ENCAP_IIS_LOG? I'm sure it's possible, and that would be a future project. The code is currently a Win32 Console app written in C++. > Note that this would require support for random access to the file when > reading it. Yes, and a whole lot more. I'm going to extend my console app to automatically determine data types, and we would need to replicate this in Wireshark if we are to read the files directly. I think there will be whole bunch more challenges, and so you can see that integrating this code into Wireshark is going to be quite a task. Going back to the main objective, what I'm proposing is that we enable a PCAP-NG file to contain any text-based data together with a schema - JSON or XML or PCAP-NG proprietary. There would be one WTAP_ENCAP_xxx type for any text-based data type. Decoding would be based on the schema data.

And is there any reason not to just take the log file reading part of your code, make it into a libwiretap module that *directly* reads those files using a WTAP_ENCAP_IIS_LOG encapsulation, and write a dissector for WTAP_ENCAP_IIS_LOG? Note that this would require support for random access to the file when reading it. ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev@wireshark.org> Archives: https://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://www.wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-requ...@wireshark.org?subject=unsubscribe ______________________________________________________________________ This message contains confidential information and is intended only for the individual named.
