ERPC has implemented a major upgrade across all regional Solana Shreds and Geyser gRPC endpoints, enhancing both defensive logic and overall performance. As network traffic on Solana continues to grow and attack patterns increase, this update strengthens nftables rules, optimizes

NAT is weird, powerful, and everywhere. so I took a deep dive into its internals using nftables in the linux kernel and wrote a little something about it. do give it a read ✨

Think you are ready for Kubernetes? Not if you skip the networking basics 👇 (Save this if you're just starting ) - CIDR Notation - Public vs Private IPs - IPv4 vs IPv6 - OSI Layers (L2, L3, L4, L7) - SSL/TLS (incl. mutual TLS) - DNS - Proxy - IPVS, IPTables & NFtables -

🚀 نسخه جدید Docker Engine 29 منتشر شد! حالا containerd به‌صورت پیش‌فرض نقش «image store» داره و پشتیبانی آزمایشی از nftables برای فایروال/شبکه لینوکس اضافه شده 🐳 یک گام بزرگ به سمت مدرنیته! توضیحات فنی بیشتر کانال تلگرام: https://t.co/20Nx9ODb86

OpenWrt真香啊，鼠标点点点就用WireGuard组了三张网的site2site隧道，即使不是子网网关也可以简单通过luci设置SNAT，比手搓iptables/nftables不知道高到哪里去了

✅ Linux firewall frontends Linux firewall frontends offer user-friendly interfaces that streamline firewall configuration by translating high-level policies into rules enforced by backends like iptables or nftables, simplifying complex management tasks. #linux #linuxuser

you can just do stuff. beginnings of my stateful nftables mutator/generator. right now it just creates random tables, but now i can nest objects in there during the init phase. later well add modification/deletion ops. this is the IR of the input:

小小猫闯大大祸之 误以为nftables的ip是双栈的，inet和inet6才是v4和v6 于是最近三个月v6的包一直在超级丢失 （不过为什么我的macbook用ping6测出来的mtu是1280，明明其他方面看着都正常）
