Abstract: Denial-of-service protection for a computing device on a first network is disclosed. In an embodiment, a packet containing a network address corresponding to a computing device on the first network is received from a source address of a second network by a gateway device. The packet includes a request to initiate a connection to the computing device on the first network. In response, an acknowledgement is transmitted to the source address. The acknowledgement includes sequence information sufficient to establish the requested connection, including a unique identifier. Subsequently received packets addressed to the network address of the computing device are forwarded by the gateway device to a corresponding network address of the computing device on the first network upon verifying a response to the acknowledgement.

Abstract: A file cabinet drawer slide assembly comprises a slide arm which is fitted with rotatable rollers, the rollers being dimensioned and configured to support a hem of a cabinet drawer. The slide arm is cooperable with a generally C-shaped track fixed to an inside side wall of the cabinet and configured to receive and support the slide arm in rolling telescoping relationship. A pivotable cam member is secured to the forward end of the slide arm in proximity to one of the rollers defining a slot through which the hem of the drawer travels. The bottom wall of the drawer is provided with a downward projection which engages a cross brace connected to the slide arm and normally prevents removal of the drawer. When the cam member is pivoted away from the hem, the drawer may be lifted sufficiently such that the projection disengages from the cross brace and the drawer can be removed from the cabinet.

Abstract: A hanging file support structure for the drawer of a file cabinet comprises a hangrail and a bracket for supporting the hangrail in a generally horizontal position within the drawer. The bracket is generally C-shaped in cross-section and has pairs of hooks extended from edges thereof which are received in slots provided in a wall of the drawer. Two sets of slots are provided in the wall of the drawer such that the bracket may selectively be supported in either of two positions thereby defining two separate positions for the hangrail to accommodate hanging file folders of different widths.
