NAMEsockstat — list open sockets
|sockstat||[-46clnu] [-f address_family] [-p ports]|
DESCRIPTIONThe sockstat command lists open Internet or UNIX domain sockets.
The following options are available:
- Show AF_INET (IPv4) sockets.
- Show AF_INET6 (IPv6) sockets.
- 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.
- Show listening sockets.
- 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.
- 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:
- The user who owns the socket.
- The command which holds the socket.
- The process ID of the command which holds the socket.
- The file descriptor number of the socket.
- The transport protocol associated with the socket for Internet sockets, or the type of socket (stream, seqpacket or datagram) for UNIX sockets.
- 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 “-”.
- The address to which the foreign end of the socket is bound (see getpeername(2)) or “-” for unconnected UNIX sockets.
HISTORYThe sockstat command appeared in FreeBSD 3.1. It was then rewritten for NetBSD 3.0.
