While troubleshooting a network problem on my
MacBook Pro
laptop, I noticed, while examining a
packet
capture file in Wireshark, that a system was
sending a lot of
User Datagram Protocol (UDP) traffic to the xxx.xxx.xxx.255 subnet
broadcast address, i.e. to all systems on the
subnet,
using port 54915 as both the source and destination
ports. The below screenshot shows what I saw when I applied
a Wireshark filter
of udp.port == 54915.
