How can I listen on a UNIX socket to watch traffic between processes?
Issue
- A UNIX socket, such as the
systemd-journalsocket or the socket forDockerorCRI-Ois being sent information from a number of processes, and a way to inspect the traffic across this socket is desired. - Typical traffic monitoring tools, such as
tcpdump, do not work on UNIX sockets.
