SOCKSTAT(1)             NetBSD 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 recog-
                 nized: 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 sym-
                 bolic 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, seq-
                      packet 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.
