Netstat results

Purpose

The information displayed on the Netstat Results Web page depends on the output type you select when using the Netstat command. The following sample results combine output for inet and UNIX address families and are not applicable to each output type selection.

The following sections describe the two types of output.

inet address families

Active Internet connections (w/o servers)
Proto Recv-Q Send-Q Local

Address

Foreign

Address

State PID/Program name
tcp 0 0 mycom-srv1:www Srv2.:2402 Established 831/
tcp 0 0 mycom-srv1:telnet Srv3:1077 Established 1969/
Name Description
Proto The protocol used by the socket.
Recv-Q The number of bytes not copied by the user program connected to the socket.
Send-Q The number of bytes not acknowledged by the remote host.
Local Address The host name of the socket.
Foreign Address The remote host name and port number of the socket.
State The state of the socket. The state might have one of the following values.
ESTABLISHED The socket has established a connection.
SYN_SENT The socket is actively attempting to establish a connection.
SYN_RECV The socket has received a connection request 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 being closed to handle packets still in the network.
CLOSED The socket is not being used.
CLOSE_WAIT The remote end has shut down, and the remote end is waiting for the socket to close.
LAST_ACK The remote end has shut down, and the socket is closed. The socket is waiting for acknowledgment.
LISTEN The socket is listening for incoming connections.
CLOSING Both local and remote sockets are shut down, but all the data is still not sent.
UNKNOWN The state of the socket is unknown.

UNIX address families

Active UNIX domain sockets (w/o servers)
Proto RefCnt Flags Type State I-Node Path
unix 7 [ ] DGRAM   33148 /dev/log
unix 0 [ ] DGRAM   42350  
unix 0 [ ] DGRAM   38530  
Name Description
Proto The protocol used by the socket.
RefCnt The reference count of processes attached through this socket.
Flags Is used for unconnected sockets if their corresponding processes are waiting for a connect request.
Type The type of socket access: SOCK_DGRAM, SOCK_STREAM, SOCK_RAW, SOCK_RDM, SOCK_SEQPACKET, SOCK_PACKET RAW.
SOCK_DGRAM The socket is used in Datagram mode (without connections).
SOCK_STREAM The socket is a stream socket.
SOCK_RAW The socket is used as a raw socket.
SOCK_RDM The socket serves reliably delivered messages.
SOCK_SEQPACKET The socket is a sequential packet socket.
SOCK_PACKET RAW The socket is an interface access socket.
UNKNOWN The socket is unknown.
State The state of the socket. For a list of possible socket states, see the description for inet address families.
I-Node The associated file for this socket, shown as an I-node number.
Path The path name of the processes attached to the socket.
