Display a list of active sockets
|
|
|
|
(protocol control blocks)
|
2014-06-04 04:18:33 +00:00
|
|
|
for each network protocol.
|
|
|
|
.Pp
|
|
|
|
The default display for active sockets shows the local
|
|
|
|
and remote addresses, send and receive queue sizes (in bytes), protocol,
|
|
|
|
and the internal state of the protocol.
|
|
|
|
Address formats are of the form
|
|
|
|
.Dq host.port
|
|
|
|
or
|
|
|
|
.Dq network.port
|
|
|
|
if a socket's address specifies a network but no specific host address.
|
|
|
|
When known, the host and network addresses are displayed symbolically
|
|
|
|
according to the databases
|
|
|
|
.Xr hosts 5
|
|
|
|
and
|
|
|
|
.Xr networks 5 ,
|
|
|
|
respectively.
|
|
|
|
If a symbolic name for an address is unknown, or if
|
|
|
|
the
|
|
|
|
.Fl n
|
|
|
|
option is specified, the address is printed numerically, according
|
|
|
|
to the address family.

The first count shows the number of unaccepted connections,
|
|
|
|
the second count shows the amount of unaccepted incomplete connections,
|
|
|
|
and the third count is the maximum number of queued connections.

Display the flowid and flowtype for each socket.
|
|
|
|
flowid is a 32 bit hardware specific identifier for each flow.
|

Direct routes are created for each

interface attached to the local host;
|

|

the gateway field for such entries shows the address of the outgoing interface.

The refcnt field gives the

current number of active uses of the route.
|
|
|
|
Connection oriented
|
|
|
|
protocols normally hold on to a single route for the duration of
|
|
|
|
a connection while connectionless protocols obtain a route while sending
|
|
|
|
to the same destination.
|
|
|
|
The use field provides a count of the number of packets
|
|
|
|
sent using that route.
|
|
|
|
The interface entry indicates the network interface utilized for the route.
