This piece talks about eBPF tools and shows how they can be used to improve system monitoring by keeping track of PTY sessions and sniffing private data like SSH, sudo, and su passwords. It shows users how to set up bpftrace, which is a necessary tool for using eBPF features, and presents ptysnoop, a more advanced tool for watching and recording what users do in SSH and terminal sessions. System administrators and security experts who want to use eBPF to improve the effectiveness and depth of system surveillance must read this piece.

A (short) collecton of eBPF enabled tools (need root privileges to run);

Prerequisite: Install the latest bpftrace tool:

curl -o bpftrace -fsSL
chmod 755 bpftrace
