The Everything Feed - All Packet Pushers Pods

Network Break episode NB573 covers Cisco open-sourcing DefenseClaw for OpenClaw AI agent security, T-Mobile's new Super Broadband service combining 5G and Starlink, and multiple AI security announcements from Aviatrix, BlueCat, and Palo Alto/Google. The hosts also discuss quarterly results from Extreme Networks, F5, and Checkpoint, and debate the sustainability of AI subsidies as GitHub moves to usage-based pricing.

Bruce Davie joins Heavy Networking to discuss a new shortest-path algorithm claimed to be faster than Dijkstra's, which has been foundational to link-state routing protocols since 1959. While the academic breakthrough is legitimate, Davie argues it has negligible practical impact on network routing because the SPF calculation represents only a tiny fraction of total convergence time. The real bottlenecks are failure detection, packet propagation at the speed of light, and forwarding table updates.

Ethan Banks and Holly Malitzky-Podbilak provide a beginner-friendly introduction to Network Access Control (NAC), covering its core concepts, protocols, and terminology including 802.1X, RADIUS, TACACS, EAP, and AAA. They discuss how NAC governs device admission and access policies on both wired and wireless networks, and survey major NAC vendor solutions in the market.

Network engineer and security developer Chris Cummings joins IPv6 Buzz to discuss the practical benefits of IPv6 for software developers, focusing on how eliminating NAT reduces complexity, improves logging, and lowers costs. The conversation also covers common pitfalls developers encounter when writing IPv6-compatible code and best practices for building address-family-agnostic applications.

Independent consultant Enrico Teodi shares 14 months of hands-on AI implementation experience at a software company, detailing how agentic workflows combining codebase access, production database replicas, and analytics tools dramatically accelerated debugging and product insights. He argues that curiosity and product understanding—not raw coding speed—determine who thrives in the AI era, and warns against giving AI excessive permissions or deploying code without proper testing and acceptance criteria.

Cisco's Han Li and Jay Sharma join the Packet Protector podcast to argue that post-quantum cryptography (PQC) is an urgent network issue, not just a future security concern. They explain how advances in quantum algorithms and hardware are accelerating the timeline, discuss the 'harvest now, decrypt later' threat, and outline practical steps organizations should take now. They also cover the technical impacts of PQC on network protocols, key sizes, and hardware procurement.

Network Break hosts Drew Connery-Murray and guest Scott Robon cover a range of networking and IT news including Cisco's quantum switch prototype, Cato Networks' enterprise browser, Anthropic's Mythos model both finding and introducing vulnerabilities, financial results from Nokia and Intel, a European satellite startup, and a Chinese company's flying car ambitions. Listener follow-up addresses concerns about Anthropic's Project Glasswing potentially exposing proprietary source code and Linux 7.0's removal of legacy protocols. Throughout, both hosts balance optimism about emerging technology with measured skepticism about vendor hype.

Scott Robon interviews Andy Smith, a distinguished engineer at Arcus Networks and Penn lecturer, at NANOG 96 in San Francisco. They discuss Andy's career spanning cable, hyperscaler, and software-defined networking, his university course on network engineering fundamentals, and the broader industry shift toward disaggregated networking, automation, and AI cluster infrastructure. The conversation emphasizes the enduring importance of first-principles thinking in an era of rapidly evolving network architectures.

Avi Friedman, founder of Kentik, joins Heavy Networking to discuss how different AI techniques — ML, fuzzy logic, and LLMs — each have distinct roles in network operations. He argues that LLMs are powerful but non-deterministic tools that require guardrails, domain-specific knowledge, and human oversight to be useful in networking contexts. The conversation covers agentic AI, hallucinations, autonomy, and the realistic near-term limits of AI in network planning and configuration.

Ray, founder of Libertas Consulting MSP and the nonprofit TKW (Technology Knowledge Worldwide), shares his journey from running bulletin board services at age 12 to building a consulting business and a charity that has donated over a million dollars in network infrastructure to communities in need. He discusses how early problem-solving instincts, key relationships, and a drive to give back shaped both ventures. His nonprofit's most ambitious project yet is a full infrastructure overhaul for the Philadelphia Ronald McDonald House.

Three infrastructure and automation veterans discuss the evolution from SOAR platforms to AI-driven automation, examining the gap between vendor demos and real-world brownfield infrastructure. They explore how DNS remains critically underappreciated from a security standpoint, and debate whether AI is creating more technical debt than it solves. The conversation emphasizes that automation and AI are tools that elevate engineers rather than replace them.

Ashwin Chosi, a senior solution engineer at Keysight Technologies, joins the Network Automation Nerds podcast to discuss how AI is reshaping networking careers. He distinguishes between 'AI for networking' and 'networking for AI' as two distinct disciplines, and shares his philosophy on continuous learning, community contribution, and using AI as an empowering tool rather than a replacement for domain expertise.

At RSA 2026, JJ and partner JD presented on network security trends from 2026-2030, covering Wi-Fi 7's security implications, device identity challenges, zero trust on the LAN, and post-quantum cryptography. The talk argues that enterprises have accumulated 'architectural debt' by iterating on existing configurations rather than rethinking foundational network design. Device identity — specifically moving away from MAC addresses — was identified as the single most critical blocker to implementing modern security architectures.

John Attil Johnson and John Burke of Nemertes discuss why AI systems require dedicated security strategies beyond standard enterprise protections. They cover specific AI threat vectors including LLM jacking, data poisoning, sleeper agent attacks, and prompt injection, while arguing that zero trust principles and robust data stewardship are foundational to any AI security posture.

Network Break episode 571 covers Linux kernel 7.0's networking upgrades including ACKECN congestion control, Netgear's FCC router ban exemption, AWS's new Interconnect service, and Amazon's acquisition of GlobalStar satellite company. The hosts also discuss Cloudflare's AI agent networking product, TSMC's massive financial results, and OpenAI's pause on UK data center expansion.

Network engineer Mark Prosser discusses with host Ethan Banks the need to redefine what constitutes a modern network service, arguing that traditional definitions are inadequate for today's complex, multi-layered networks with overlays, cloud components, and organizational silos. They explore how service validation and testing should be integral to service definition and delivery.

The hosts discuss IPv6 privacy and temporary addresses, explaining how they evolved from EUI-64's trackability issues to provide client devices with randomized interface identifiers. They clarify the distinction between permanent privacy addresses (stable, DNS-registered) and temporary privacy addresses (frequently rotated for external connections).

This episode of 'N4N053: Well Actually 03' is a community feedback episode where hosts Ethan Banks and Holly Mitlitsky respond to listener comments, questions, and suggestions. They address feedback on multicast, networking fundamentals, career advice for beginners, and various technical topics while expressing gratitude for the active community engagement.

Jen Geil, co-founder of Open Source Malware, discusses the dramatic surge in malware targeting open source packages, particularly NPM, with AI being used both to create and exploit vulnerabilities. She reveals that over 90% of open source malware is found in NPM packages, with attacks increasingly targeting AI tools and agent marketplaces.

HPE's VP Mundani Adjali discusses the formation of HPE Threat Labs from the merger of Juniper and HPE Aruba threat research teams. The conversation covers cybercrime professionalization, AI's impact on threats, network visibility challenges, and the critical need for better patch management across enterprise systems.
