…racking - Added an eBPF program in Rust using aya to track SSH (port 22) connection attempts. - Attached as a kprobe to tcp_v4_connect. - Extracts PID and destination IPv4 from sockaddr. - Stores attempt counts in a BPF HashMap keyed by (PID, IP). - Implemented a Go userspace loader using cilium/ebpf: - Loads and attaches the compiled ssh_monitor.o. - Periodically reads from the ssh_attempts map and prints the PID/IP/Count. - Gracefully handles SIGINT/SIGTERM for clean shutdown. Tested locally with loopback SSH connections. Working end-to-end integration between kernel-level probe and userland reporting.
