How can I find process listening on UDP port?

I've never seen this before so not sure what's happening.

netstat -lup

just shows "-" in the PID/Program Name column

ss -uap

doesn't show any processes either.

The UDP port in question is 8472. I'm hoping this has something to do with linode infrastructure / cisco routers :)

You'll need to sudo to get the process info:

sudo netstat -lup

This is from a new Linux kernel VXLAN option that I will be turning off in the next kernels we release.
