netstat还可看到服务层面？
他的state就是下面这些：
State
The state of the socket. Since 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
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 don鈥檛 have all our data sent.
UNKNOWN
The state of the socket is unknown. |
