The port numbers list at
http://www.isi.edu/in-notes/iana/assignments/port-numbers lists port
5456 as belonging to 'apc-tcp-udp-6', followed by a contact address at
APC, the UPS manufacturer. Are you running any sort of UPS software?
The unchanging source port indicates that a process is hanging around with
the socket open. If you have 'lsof' or 'fuser' installed, you should be
able to track it down with 'lsof -i udp:1069' or 'fuser -n udp 1069'. I
believe newer versions of 'netstat' under Linux can also show the PID of
each socket's owner.
