NAME
sockstat
- list open sockets
SYNOPSIS
[-46clu
]
[-p ports
]
[-P protocols
]
DESCRIPTION
The
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.
-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,
will list sockets in all three domains.
If neither
-c
or
-l
is specified,
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.
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)).
Note that TCP sockets in the
AF_INET
or
AF_INET6
domains that are not in one of the
LISTEN , SYN_SENT
or
ESTABLISHED
states may not be shown by
;
use
netstat(1)
to examine them instead.
