The fact that you happen to have traffic on port 2673 doesn't
necessarily mean you're running that software - the networking stack on
some machine might have just happened to pick that port number for a TCP
client's socket, for example.

TCP and UDP port numbers are *NOT* 100% reliable indicators of the
traffic using the port number, although some port numbers might be more
reliable indicators than others.
