State
Description
State of the socket. Because there are no states in raw
mode and usually no states used in UDP, this column
may be left blank. Normally this can be one of several
values:
•
ESTABLISHED—The socket has an established
connection.
•
SYN_SENT—The socket is actively attempting
to establish a connection.
•
SYN_RECV—A connection request has been
received from the network.
•
FIN_WAIT1—The socket is closed, and the
connection is shutting down.
•
FIN_WAIT2—The connection is closed, and the
socket is waiting for a shutdown from the
remote end.
•
TIME_WAIT—The socket is waiting after close
to handle packets still in the network.
•
CLOSED—The socket is not being used.
•
CLOSE_WAIT—The remote end has shut down,
waiting for the socket to close.
•
LAST_ACK—The remote end has shut down,
and the socket is closed. Waiting for
acknowledgement.
•
LISTEN—The socket is listening for incoming
connections. Such sockets are not included in
the output unless you specify the --listening (-l)
or --all (-a) option.
•
CLOSING—Both sockets are shut down but we
still do not have all our data sent.
•
UNKNOWN—The state of the socket is
unknown.
