I have installed and run docker and now it created another network interface docker0:
3: docker0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default link/ether 06:19:32:11:AD:18 brd ff:ff:ff:ff:ff:ff inet xx.xx.xx.xx/16 scope global docker0 valid_lft forever preferred_lft forever inet6 ab90::43:2af:fe30:2245/64 scope link valid_lft forever preferred_lft forever
Even when stopping the docker service this interface is still up. How is it possible to see all open/listening ports on all interfaces (eth0, wlan0 and docker0)? I've tried using lsof but I couldn't find any interface granularity options.
