SOCKSTAT(1)		  BSD General Commands Manual		   SOCKSTAT(1)

     sockstat -- list open sockets

     sockstat [-46cLlu]	[-j jid] [-p ports] [-P	protocols]

     The sockstat command lists	open Internet or UNIX domain sockets.

     The following options are available:

     -4		 Show AF_INET (IPv4) sockets.

     -6		 Show AF_INET6 (IPv6) sockets.

     -c		 Show connected	sockets.

     -j	jid	 Show only sockets belonging to	the specified jail ID.

     -L		 Only show Internet sockets if the local or foreign addresses
		 are not in the	loopback network prefix, or	do not
		 contain the IPv6 loopback address ::1.

     -l		 Show listening	sockets.

     -p	ports	 Only show Internet sockets if either the local	or foreign
		 port number is	on the specified list.	The ports argument is
		 a comma-separated list	of port	numbers	and ranges specified
		 as first and last port	separated by a dash.

     -P	protocols
		 Only show sockets of the specified protocols.	The protocols
		 argument is a comma-separated list of protocol	names, as they
		 are defined in	protocols(5).

     -u		 Show AF_LOCAL (UNIX) sockets.

     If	neither	-4, -6 or -u is	specified, sockstat will list sockets in all
     three domains.

     If	neither	-c or -l is specified, sockstat	will list both listening and
     connected sockets.

     The information listed for	each socket is:

     USER	      The user who owns	the socket.

     COMMAND	      The command which	holds the socket.

     PID	      The process ID of	the command which holds	the socket.

     FD		      The file descriptor number of the	socket.

     PROTO	      The transport protocol associated	with the socket	for
		      Internet sockets,	or the type of socket (stream or data-
		      gram) for	UNIX sockets.

     LOCAL ADDRESS    For Internet sockets, this is the	address	the local end
		      of the socket is bound to	(see getsockname(2)).  For
		      bound UNIX sockets, it is	the socket's filename.	For
		      other UNIX sockets, it is	a right	arrow followed by the
		      endpoint's filename, or "??" if the endpoint could not
		      be determined.

     FOREIGN ADDRESS  (Internet	sockets	only) The address the foreign end of
		      the socket is bound to (see getpeername(2)).

     If	a socket is associated with more than one file descriptor, it is shown
     multiple times.  If a socket is not associated with any file descriptor,
     the first four columns have no meaning.

     fstat(1), netstat(1), procstat(1),	inet(4), inet6(4), protocols(5)

     The sockstat command appeared in FreeBSD 3.1.
