Abstract: There is provided a system and method for remote management of a computer. The method includes establishing a connection between a remote console and a managed server. Additionally, the method includes detecting a change in the status of the connection and issuing commands to lock the managed server if a change in status of the connection is detected.

Abstract: In one embodiment, a first client device establishes a remote session between a remote computing device and the first client device. One or more subsequent client devices that attempt to establish a remote session with the remote computing device are re-directed to another computing device that serves as a host for the remote session.

Abstract: A method and apparatus of remotely accessing a computer system by a remote console includes receiving, by an emulation device, pointer position data representing a position of a first pointing device of the remote console. The emulation device emulates a second pointing device that is of a different type than the first pointing device. The emulation device generates data representing a position of the second pointing device based on the received pointer position data representing the position of the first pointing device.

Abstract: In at least some embodiments, a computer system may comprise a CPU and a system memory coupled to the CPU. The computer system may further comprise a management device coupled to the CPU and the system memory. The management device is operable to permit remote control of the computer system by other computer systems. The management device is configured to receive a signal when the computer system malfunctions and, in response to receiving the signal, perform a data dump of at least some of the data in the system memory without involvement of the CPU.

Abstract: The disclosed embodiments relate to the field of remote server management. More particularly, the disclosed embodiments relate to providing secure communications in the context of remote server management. In an exemplary embodiment of the invention, a client computer uses an established encrypted communication channel to request secret data from a managed server. The managed server provides the requested secret data, which is used by both the managed server and the client computer to encrypt communications across a second communications link.

Abstract: A technique is provided for identifying the write protect status of a removable storage media, such as a computer diskette, prior to normal interaction with the media. The present technique interacts with the removable storage media and identifies the write protect status as write protected if the interaction produces a failure code indicative of write protection. For example, data storage may be attempted at a non-storage location, thereby producing a write protect error if the media is write protected or an invalid write error if the media is not write protected. Alternatively, the present technique may attempt to read and rewrite data back to the media, thereby producing the write protect error if the media is write protected.

Abstract: A method for resetting a password in a computer system is provided. A remote reset signal is received. A local reset verification signal is received at the computer system. An elapsed period of time between receipt of the remote reset signal and the local reset verification signal is determined. The password is reset in response to the elapsed period of time being less than a predetermined time period.

Abstract: A disk cache writing system that substantially improves disk drive caching. A cache disk drive, or a reserved portion of a standard disk drive, is provided that is dedicated to cache data. Any of the current data of the disk drive or cache portion is temporary cache data that may be overwritten at any time. Cache data is written to a write section, including one or more sequential sectors, where the write section has a minimal write access time. The write section begins at a first offset sector associated with a minimal write access time, or at any one of several potential start sectors including the first offset sector. One or more potential start sectors are determined, where each corresponds with a first start sector in a current track to avoid moving the R/W heads from the current track. The only initial delay that is encountered is the delay to switch the R/W heads from read to write.

Abstract: A technique is provided for authenticating a client for multiple network devices and services using a single sign-on mechanism. The present technique stores client credentials at each of the multiple network devices and services, which generate and transform an authentication challenge (e.g., a random number) using an appropriate one of the client credentials stored thereon. At the client-side, the single sign-on mechanism stores client credentials entered during a first authentication process. Subsequent authentication processes simply retrieve the client credentials stored by the single sign-on mechanism during the first authentication process. The technique then independently transforms the authentication challenge received at the client-side using the client credentials at the client-side. The technique then authenticates the client if the independent transformations produce an equivalent result.

Abstract: The disclosure relates to a remote server management controller that is adapted to be incorporated into a managed server. The disclosed embodiments allow a remote user to communicate with the managed server using out-of-band management communications that are not dependent on the OS of the managed server. The user may obtain management data from the OS or perform other functions remotely by causing the managed server to redirect data from its local communications interfaces to communications interfaces that are available to the remote user.

Abstract: A computer system is implemented according to the invention when priority information is included with a bus transaction. Instead of processing bus transactions on a first-come-first-served basis, a computer peripheral device can make decisions about the relative importance of a transaction and process the most important ones first. The priority scheme can be based upon the priority of the process that generates the transaction or on any other scheme. Included in the invention is logic to ensure that transactions of low relative priority do not get completely ignored during periods of high activity.
