Using Ubuntu Server 16. Something on my machine has an SCTP port open, and I need to find it and kill it (without rebooting).
lsof doesn't show SCTP sockets, only TCP and UDP.
I'm looking through all these network utilities, and SCTP support is surprisingly scarce for such an old standard. I got
netstat to work with SCTP by building the bleeding edge net-tools from here.
sudo netstat --sctp -tulpn shows some open SCTP connections but doesn't say which process has them. It only shows the PIDs for UDP and TCP sockets.
