[Bug 1671974] Re: CUPS - Excessive Amounts of UDP Multicast Traffic for BJNP

I experience the same symptoms on Ubuntu 19.04 disco, but there is no cups* packages installed: # apt-cache policy cups*| grep Installed | grep -v none # The issue is definitely unrelated to CUPS. Some other process sends many strange IPv6/UDP packets to all IPv6 local nodes with 2 different types; the wireshark trace shows 2 types of "Discover scanner commands": 1. source port 8612 (canon-bjnp2) --> dest port 8610 (canon-mfnp) 2. source port 8612 (canon-bjnp2) --> dest port 8612 (canon-bjnp2) I have no canon device on the network nor on the server and no USB device connected on the server. There is no canon related package/kernel module installed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1671974 Title: CUPS - Excessive Amounts of UDP Multicast Traffic for BJNP To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1671974/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I also see the IPv6 requests when a USB device is plugged in. In this case it is a Z-Wave device. I don't have any cannon stuff.
