SYNOPSIS¶
| sockstat |
[-clh]
[-p ports]
[-P
pid|process]
[-U
uid|user]
[-G
gid|group] |
DESCRIPTION¶
The
sockstat command lists open Internet or
UNIX domain sockets.
The following options are available:
- -c
- Show connected sockets.
- -l
- Show listening sockets.
- -h
- Show a usage summary.
- -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
pid|process
- Only show sockets of the specified
pid|process. The pid|process
argument is a process name or pid.
- -U
uid|user
- Only show sockets of the specified
uid|user. The uid|user
argument is a username or uid.
- -G
gid|group
- Only show sockets of the specified
gid|group. The gid|group
argument is a groupname or gid.
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.
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)).
