摘要： A method and apparatus are provided for passing configuration information over a network. In one embodiment, the configuration information is passed between a DHCP server and a DHCP client and includes parameters not formally defined within DHCP. The parameters are therefore encoded into a vendor-specific portion of a DHCP message using at least one triplet comprising a code field, a length field, and a value field. The value field comprises a set of one or more name-value pairs. The code field includes an indication of encryption of the value field. In another embodiment, a fixed-function appliance device is attached to a network, and is booted using boot code and a configuration stored locally to the device. The device then downloads a network configuration, which is compared to the locally stored configuration. If the network configuration is different from the locally stored configuration, the network configuration is stored locally to the device. The device is then rebooted using the stored network configuration.

摘要： A computer system is connectable to a network. The computer system includes a plurality of processing units, each of the processing units being provided with a respective network identity for communication with the network. At least one service processor is operable to allocate network identities to the processing units. A switch is provided for interconnecting the processing units to the network. The switch is operable to maintain a record of the network identities allocated to the processing units by the service processor and filters network access by each processing unit such that network access is blocked where a processing unit identity does not correspond to that held by the switch. By maintaining a record of the network identities allocated to the processing units by the service processor in the switch and filtering network access, access by a processing unit that has been changed or where its network identity has otherwise changed, can be prevented, maintaining the integrity of the network.

摘要： A first host system can be configured initially with a first host identity and a second host system can be configured initially with a second host identity. A host identity can belong to only one host system at a time. An administrator system can hold an additional host identity. The administrator system can securely connect to the first host system and can pass the additional host identity to the first host system. The first host system can reconfiguring itself to use the additional host identity and can pass the first host identity to the administrator system. The administrator system can securely connect to the second host system and can pass the first host identity to the second host system. The second host system can then reconfigure itself to use the first host identity and pass the second host identity to the administrator system. In this manner the first host identity can be passed securely from the first to the host system without a risk of duplication.

摘要： First and second host systems can each include a respective repository of host identities. The first host system can encode a host identity to be transferred to the second host system using a parameter, for example a property of the second host system. The first host system can divulge the result of the encoding and remove the host identity from its repository. The second host system can decode the host identity to be transferred using the parameter, and can then add the host identity to be transferred to its repository.

摘要： Monitoring the health of a system module can be carried out during state transitioning, for example when starting or stopping a system module. A monitor module can be operationally connected to the system module. The system module can output a status signal for predetermined system status points during state transitioning. The monitor module can start a timer on detecting a first status signal and can reset the timer on detecting a subsequent status signal. The timer can indicate a failed transitioning of the system module in the event that the timer is not reset within a determined period of being reset.

摘要： A file server system tolerant to hardware and software failures is located over a plurality of hardware nodes. The nodes of the system act as hosts for software components of the system. Several of the software components can be replicated. The replicable software components include the system file store, a checker and a logger. The replicated components have one primary copy and one or more back-up copies. Replica copies of a given replicated component are each located at different nodes. Location and handling of replica copies of a given replicable component is under the control of a replication manager which is a (non-replicable) software component of the system. The replication manager is distributed meaning it can have one of its instances running on each node of the system. These instances inter-communicate to maintain coherence. The failure detector is also distributed, its instances running on each of the nodes, and contributing to an early detection of hardware and software failures. The file store is configured to hold stored objects and includes a signature generator for computing an object-specific signature from an object. The checker comprises a signature store for holding a previously computed signature for each of the stored objects and a comparator operable to compare a signature retrieved from the signature store with a corresponding signature computed by the signature generator from an object retrieved from the file store, thus to enhance system reliability.
摘要翻译： 容忍硬件和软件故障的文件服务器系统位于多个硬件节点上。 系统的节点充当系统软件组件的主机。 可以复制几个软件组件。 可复制的软件组件包括系统文件存储，检查器和记录器。 复制的组件具有一个主要副本和一个或多个备份副本。 给定复制组件的副本副本各自位于不同的节点。 给定可复制组件的副本副本的位置和处理由复制管理器控制，复制管理器是系统的（不可复制的）软件组件。 复制管理器是分布式的，意味着它可以使其一个实例在系统的每个节点上运行。 这些实例相互通信以保持一致性。 故障检测器也被分布，其实例在每个节点上运行，并有助于早期检测硬件和软件故障。 文件存储被配置为保存存储的对象，并且包括用于从对象计算对象特定签名的签名生成器。 检查器包括用于保存用于每个存储对象的先前计算的签名的签名存储器，以及比较器，用于将从签名存储检索到的签名与从文件存储器检索到的对象由签名生成器计算的对应签名进行比较，从而 以提高系统的可靠性。
