    摘要: In general, the invention is directed to techniques for verifying the integrity of a file system and individually verifying files contained therein based on the integrity of the file system. For example, a computer-based device is described in which a computer-readable storage medium stores a file system stored as an image file. The device comprises a virtual file system comprising a mount list entry that corresponds to the file system, wherein the file system is mounted on the virtual file system, and wherein the mount list entry comprises a first verified flag that indicates whether the file system is verified. A verified execution module determines whether the image file is corrupt, and a kernel module sets the first verified flag when the image file is not corrupt. An image verify module verifies the integrity of files stored by the file system by determining whether the file system is verified.

    摘要: A network device includes an initial data source to store configuration data for the network device, and a management module to generate a configuration patch that lists any differences between a working copy of the initial data source and the initial data source. The management module modifies the working copy based on configuration commands received from a client, and updates the initial data source in accordance with the differences defined by the configuration patch. During the update process, the management module verifies that any conditions specified by the patch are satisfied. The management module may generate the configuration patch in response to a first command from a client, and apply the patch in response to a second command from the client. The configuration patch may be communicated to other network devices for configuring the devices.

    摘要: In general, this disclosure relates to techniques for allowing multiple clients to concurrently configure a network device. More specifically, a management module creates a working copy of an initial data source that stores configuration data for a network device and modifies the working copy to reorder one or more configuration objects in a list in response to configuration commands from a client. Upon receiving a show|compare command or a commit command, the management module generates a configuration patch that is a textual representation of any differences between the working copy and the initial data source. The configuration patch includes modification control indicators that identify configuration objects in the list that are reordered. The patch is applied to the initial data source to reorder the list of configuration objects within the initial data source without processing portions of the configuration data associated with the reordered configuration.

    摘要: Techniques are described that configure a router in a configuration mode specified by a client. For example, a client may request to configure the router in a private configuration mode. In response to the command, a management module creates a private database. A client may edit the configuration data of the private database. The client may edit the private database without interference from other clients that may also be editing configuration data of the router. Management server module updates the committed database with edited private database, and the router begins to operate in accordance with the updated configuration data.

    摘要: In general, the invention is directed to techniques for establishing secure connections with devices residing behind a security device. In accordance with the techniques, a managed device initiates a transmission control protocol (TCP) session to establish a TCP session with a management device such that the management device acts as the TCP server and the managed device acts as a TCP client. Once established, the managed device sends a role reversal message specifying an identity of the managed device via the TCP session. Upon receiving the role reversal message, the management device initiates a secure connection over the TCP session in accordance with a secure protocol such that the management device acts as the secure protocol client and the managed device acts as the secure protocol server. By properly establishing the secure session, each of the devices assumes the proper roles and administrators may more easily configure the devices.

    摘要: A system and method may assist in securing data for transmission to a receiving entity. Received data may include metadata associated therewith. The data may be encrypted using an encryption key encoded within selected portions of the metadata, where the selection of the selected portions is based on a scheme shared with the receiving entity. The encrypted data including the metadata may be transferred to the receiving entity. The receiving entity may decrypt the encrypted data using the selected portions of the metadata.
