Exporting PCAP to Database

Hi guys!

I'm working on a little program to convert .PCAP files into MySQL tables, in order to make analysis easier (a program that I will share here as soon as is finished, naturally).

My first command is running on a Windows console and outputs a very nice filtered .pcap file, filled with information.

tshark -r "C:\proyecto \20210729_15_45-MIRR-BKP.pcap" -Y camel -w "C:\proyecto\20210729_15_45-MIRR-BKP_filtered.pcap"

However, on my next step, converting the aforementioned .PCAP to JSON, I'm getting a blank JSON file.

tshark -r "C:\proyecto\20210729_15_45-MIRR-BKP_filtered.pcap" -T json -w "C:\proyecto\20210729_15_45-MIRR-BKP.json"

I used the code provided by @Chuckc on this post.

Once I get the .JSON part working, I'll implement a little UI to select what packet information will be exported, etc.

Thank you and best regards

@Chuckc provided the answer to this question in his comment. Quoting him:

NOTE: -w provides raw packet data, not text. If you want text output you need to redirect stdout (e.g. using '>'), don't use the -w option for this.

Thank you very much!

I turned his comment into an answer. (That option might not have been offered to you, as you might not have had the privileges to do so.)

From the tshark man page:

NOTE: -w provides raw packet data, not text. If you want text output you need to redirect stdout (e.g. using '>'), don't use the -w option for this.
