SOCKSTAT(1)             FreeBSD General Commands Manual            SOCKSTAT(1)

NAME
     sockstat - list open sockets

SYNOPSIS
     sockstat [-46clu]

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.

     -l          Show listening sockets.

     -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
                      datagram) for UNIX sockets.

     ADDRESS          (UNIX sockets only) For bound sockets, this is the
                      filename of the socket.  For other sockets, it is the
                      name, PID and file descriptor number of the peer, or
                      ``(none)'' if the socket is neither bound nor connected.

     LOCAL ADDRESS    (Internet sockets only) The address the local end of the
                      socket is bound to (see getsockname(2)).

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