SOCKSTAT(1) BSD 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 recognized: 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 symbolic 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, seqpacket or data-
gram) 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.
