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 data-
gram) for UNIX sockets.
ADDRESS (UNIX sockets only) For bound sockets, this is the file-
name 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)).
