The NAVV (Network Architecture Verification and Validation) tool creates a spreadsheet for network traffic analysis from PCAP data and Zeek logs, automating Zeek analysis of PCAP files, the collation of Zeek logs and the dissection of conn.log and dns.log to create a summary or network traffic in an XLSX-formatted spreadsheet.

Problem download updated spreadsheet file #70

Open syrinxtech opened 2 months ago

🐛 Summary

What's wrong? Please be specific. I captured PCAP data using tcpdump. Then I ran zeek via cmd line to read PCAP data, and created the Excel spreadsheet. I updated the spreadsheet to add the segment tab CIDR and color info. When I run navv again and try to update the spreadsheet the download process craps out.

To reproduce

Steps to reproduce the behavior:

  1. Do this
  2. source venv/bin/activate
  3. Then this
  4. navv launch

Expected behavior

What did you expect to happen that didn't? I expected navv to update the spreadsheet after I added the CIDR range and colored it.

Any helpful log output or screenshots

I also noticed that about 95% of the time when I first type "navv launch", the first attempt to start Firefox fails and I have to retry. The first retry almost always works.
