NAME


sockstat — list open sockets

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)).
