+.TH netstat 8 MiNT-Net
+.SH NAME
+netstat \- show active network connections
+.SH SYNOPSIS
+.B "netstat [-f domain]"
+.SH DESCRIPTION
+.I Netstat
+is used to display infomation about active communication
+endpoints in either the
+.B unix
+or
+.B inet
+communication domain or both of them.
+If invoked without arguments it shows only
+.B unix
+domain sockets.
+You can specify the domain to deal with with the -f option.
+.sp
+For the unix domain the output of netstat consists of one line for
+each socket in the system,
+which contains the following entries:
+.TP 15
+.SM "Proto"
+The protocol used by the socket, this can be one of:
+.RS 15
+.TP 15
+.SM "unix"
+This is the one and only protocol for unix sockets.
+.TP
+.SM "unknown"
+The protocol is unknown, should never happen.
+.RE
+.TP 15
+.SM "Flags"
+These are the flags set on the socket. The output for this entry
+consists of a space-separated list of tree-letter flag values.
+Possible flags are:
+.RS 15
+.TP 15
+.SM "ACC"
+The socket is listening for incoming connections.
+This applies only to stream sockets.
+.TP
+.SM "RCV"
+The socket is shut down for receiving after a call to
+.IR shutdown (3),
+ie the socket cannot receive any messages.
+.TP
+.SM "SND"
+The socket is shut down for sending after a call to
+.IR shutdown (3),
+ie it is impossible to send messages on the socket.
+.TP
+.SM "MRK"
+If out-of-band data is handled inline, "receiving is at mark", ie
+all data before the out of band data has been read.
+.RE
+.TP 15
+.SM "State"
+This field is the internal state of the socket,
+the following values are possible:
+.RS 15
+.TP 15
+.SM "VIRGIN"
+The socket has just been created,
+but has not been assigned a communication domain and type.
+.TP
+.SM "UNCONNECTED"
+The socket is not connected to a peer.
+.TP
+.SM "CONNECTING"
+The socket is about to connect to another one.
+.TP
+.SM "CONNECTED"
+The socket is connected to another one.
+.TP
+.SM "DISONNECTING"
+The socket is about to finish the connection to its peer.
+.TP
+.SM "DISCONNECTED"
+The socket has finished a connection and is again unconnected.
+.TP
+.SM "UNKNOWN"
+This should never happen.
+.RE
+.TP 15
+.SM "Type"
+This is the communication style the socket uses.
+Possible values are:
+.RS 15
+.TP 15
+.SM "STREAM"
+The socket uses connection-oriented byte stream communication,
+just like pipes do.
+.TP
+.SM "DGRAM"
+The socket uses connectionless, unrelyable,
+datagram oriented communication.
+.TP
+.SM "RAW"
+This is a raw socket.
+.TP
+.SM "RDM"
+Just like
+.SM "DGRAM\c"
+, except that you can rely on the packets to be delivered successfully.
+.TP
+.SM "SEQPACKET"
+This is like
+.SM "RDM\c"
+, except that the receiver is guaranteed to get the packets in the
+same order the sender sends them.
+.TP
+.SM "UNKNOWN"
+This type should never happen.
+.RE
+.TP 15
+.SM "Recv-Q"
+The size of the next unread message for datagram oriented sockets,
+and the number of unread bytes for stream oriented ones.
+.TP
+.SM "Address"
+The local address of the socket, if
+.IR bind (3)
+was done on it.
+This is a filename for the unix domain.
+.SH OPTIONS
+.TP 15
+-f domain
+Display information for active sockets in domain
+.IR domain ,
+overriding the default domain.
+.SH FILES
+.TP 15
+/dev/unix
+Unix domain information
+.SH BUGS
+Only unix domain implemented.
