    An implementation of the SOCKSv4 protocol.

    @type logging: C{str} or C{None}
    @ivar logging: If not C{None}, the name of the logfile to which connection
        information will be written.

    @type reactor: object providing L{twisted.internet.interfaces.IReactorTCP}
    @ivar reactor: The reactor used to create connections.

    @type buf: C{str}
    @ivar buf: Part of a SOCKSv4 connection request.

    @type otherConn: C{SOCKSv4Incoming}, C{SOCKSv4Outgoing} or C{None}
    @ivar otherConn: Until the connection has been established, C{otherConn} is
        C{None}. After that, it is the proxy-to-destination protocol instance
        along which the client's connection is being forwarded.

        The second half of the SOCKS connection setup. For a SOCKSv4 packet this
        is after the server address has been extracted from the header. For a
        SOCKSv4a packet this is after the host name has been resolved.

        @type server: C{str}
        @param server: The IP address of the destination, represented as a
            dotted quad.

        @type user: C{str}
        @param user: The username associated with the connection.

        @type version: C{int}
        @param version: The SOCKS protocol version number.

        @type code: C{int}
        @param code: The comand code. 1 means establish a TCP/IP stream
            connection, and 2 means establish a TCP/IP port binding.

        @type port: C{int}
        @param port: The port number associated with the connection.
