How to Log connections

edit

Hi, How can I log ROS TCP connection creations and destructions? I'm trying to move all my clients to persistent connections to avoid recreating too many TCP sockets (to avoid they dangle for a couple of minutes), but I still have many TIME_WAIT connections (for which I cannot see to which process they belong with netstat nor lsof -i)

Maybe enabling logs for roscore? We have diamondback but we're migrating soon to electric.

thanks
