First, start tcpdump listening on all interfaces, saving full sized packets, and writing the results to a pcap file: sudo tcpdump -i any -s 65535 -w example.pcap.

GitHub - hsouna/tls-servername: This python script retrieves server names from the TLS extension (in the Client Hello) using scapy. Scrapy is a fast high-level web crawling and web scraping framework, used to crawl websites and extract structured data from their pages. It is able to forge or decode packets of a wide number of protocols, send them on the wire, capture them, match requests and replies, and much more.
