Every second, a typical production server can create over a hundred log entries. Most administrators never see them—until something breaks. I treat this data as my primary superpower. When a server fails, these recorded notes tell me exactly what happened. They are the first place I look. These files are a continuous record. Every user […]
I will walk you through a working eBPF IDS Linux setup that hooks kernel events, streams signals to user space, and keeps performance predictable. I start from how the verifier and JIT work in the linux kernel so you can pick the right attach points. I explain kprobes, tracepoints, uprobes, XDP, and LSM in plain […]
Profile-bpfcc samples CPU stacks in-kernel without recompiling, showing exactly where cycles burn in kernel and userspace with minimal overhead.
bpffs mount requires CAP_SYS_ADMIN for both the mount and bpf() syscall. Learn how to diagnose failures, make mounts persistent, and secure pins across reboots.
Live patching fixes CVEs in place without rebooting, but kernel version upgrades need kexec or a restart. Learn which tool solves your actual problem.
tracepath finds broken routes and shrinking packet sizes without root access on Debian. Install from iputils-tracepath, run in seconds, skip the sudo hassle.
TP-Link SG2210XMP-M2 leads our tested PoE switches for homelabs, offering 2.5G ports and 10G uplinks. Compare fanless options with real PoE budgets.
luci-app-nlbwmon attributes OpenWrt traffic to IP and MAC addresses, explains apk versus opkg installs, and helps troubleshoot missing or misleading totals.
BCC compiles eBPF C at runtime for deep Linux kernel tracing. Learn when to use BCC versus CO-RE, which tools solve real problems, and how to write safe probes.
Pixie uses eBPF to auto-instrument Kubernetes workloads, capturing HTTP, gRPC, and TLS traffic at the kernel level with zero code changes or sidecars.
Falco requires modern eBPF drivers, DaemonSet deployment, rule tuning, and Falcosidekick integration to catch runtime threats in production clusters.
