Excited to read the title of this post. I've been searching for general pcap labs recently to sharpen my packet analysis skills. A little disappointed to see it's from CNTDA (since i've already done the labs from 7th ed). It's been a while though perhaps I will revisit these labs for the 8th ed.

This site also offers a ton of pcaps but not necessarily in exercise/lab format https://www.netresec.com/?page=PcapFiles
