  1. Ah, nothing quite like reading a thrilling #novella about TCP socket woes where #ECONNRESET is the main character and "reproducer" makes a cameo appearance! 📚✨ Spoiler alert: Our daring hero bravely navigates the murky waters of #tcpdump, #strace, and... zzz. Wake me when they reboot the server! 🤦‍♂️💤

  6. Scratched an itch that's been bothering me for a while. I created a vpp-pcap tool to serve network engineers working with #VPP who want something akin to #tcpdump.

    VPP has some very rich tracing tools, but I find them ergonomically challenging to use. I came up as a network engineer in the late 90s and early 2000s - this feels much more natural to me.

    The repository is on GitHub. Both a plugin and a small Rust utility are used to provide live access to data passing through the VPP dataplane. It can also be chained with tcpdump, tshark, or wireshark to use those familiar interfaces. Usage details are in the GitHub README.
