How can I list all connections to my host, including those to LXC guests?












3















I tried both netstat and lsof, but it appears it's not possible to see the connections to my LXC guests.



Is there a way to achieve this ... for all guests at once?





Essentially what throws me off here is the fact that I can see the processes of the guests as long as I run as superuser. I can also see the veth interfaces that get dynamically created per guest. Why can I not see connections on processes that are otherwise visible?

          So basically, the only way is a loop around your containers and nsenter.

            So far I had luck getting the container connections by running netstat from the container:



            sudo docker exec -it <containerIdOrName> netstat


            Obviously, the container needs to have it installed.
