Hi, When reading manpage of auditd.conf, I found "heartbeat" in the explanation of " tcp_client_max_idle". But in the manpage of audisp-remote.conf there is no description about it. How to use "tcp_client_max_idle" and what is "heartbeat"? What will happen if "tcp_client_max_idle" and "heartbeat" is not set as zero? Regards Chu Li
