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

NAME
     sockstat -- list open sockets

SYNOPSIS
     sockstat [-46clnu] [-f address_family] [-p ports]

DESCRIPTION
     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.

     -f address_family
		 Limit listed sockets to those of the specified address_family.  The following
		 address families are recognized: inet, for AF_INET; inet6, for AF_INET6; and
		 local or unix, for AF_LOCAL.

     -l 	 Show listening sockets.

     -n 	 Numeric output only.  No attempt will be made to look up symbolic names for
		 addresses and ports.

     -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.

     -u 	 Show AF_LOCAL (UNIX) sockets.

     If neither -4, -6, nor -u are specified, sockstat will list sockets in all three domains.

     If neither -c nor -l are specified, sockstat will list both listening and connected sockets,
     as well as those sockets that are in neither state.

     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, seqpacket or datagram) for UNIX sockets.

     LOCAL ADDRESS    For Internet sockets, this is the address to which the local end of the
		      socket is bound (see getsockname(2)).  For bound UNIX sockets, it is the
		      socket's filename or ``-''.

     FOREIGN ADDRESS  The address to which the foreign end of the socket is bound (see
		      getpeername(2)) or ``-'' for unconnected UNIX sockets.
