Source address/port – local port—Shows the 32 most recent TCP
connection attempts that were rejected, including the remote node’s IP
address and port, the local port for the connection attempt, and the
number of identical attempts that have been received on that port in a
row. The reason for rejection is not given. This information may be
useful in tracking down DoS attacks.
