- 13:32, 20 June 2024 Helpful talk contribs created page Tcpdump notes (Created page with " {{notes}} TCPdump snoops network traffic going getting to the host it runs on. It can also filter what packets it shows/writes. It can summarize the traffic on-screen (the default) or write it to the fairly common pcap-style files. The 'tcp' in the name is misleading, because it suggests it captures at the network layer, and then specifically TCP. Actually, it captures at link layer, so you can get at a lot of interesting stuff. Wireshark (previously Ethereal)...")

It's a term related to compilation execution, because it means a block is parsed completely before it starts running it, and the exact ordering doesn't matter.
