Methods, systems and computer program products are provided that may relate to controlling access to or accessing computer files over a computer network. A file server may execute on a first computer system and a client may execute on a second computer system. The client may be configured to send a first communication to the file server relating to a first computer file stored on the first computer system. The first communication may include first access control data associated with the first computer file. The file server may be configured to receive the first communication and extract the first access control data from the first communication. The file server may then store the extracted first access control data in extended attributes of the first computer file on the first computer system.

Accessing and providing access to computer files over a computer network

A request to write new data to a file is received. The file occupies a pre-determined size of storage space in a file-system. A determination is made whether an end location amount of space from an ending location value in an attribute up to the pre-determined size is insufficient to write the new data to the file. A second amount of space is computed. The first and the second amounts of space together are sufficient to write the new data. The second amount of space begins at a starting location value in a starting location attribute. The new data is written using the first and the second amounts of space. The ending location value is changed to indicate a location at the end of new data in the second amount of space. The starting location value is changed to indicate a location where existing data begins after new data.

Managing log data using a circular fixed size file

A method, system, and computer program product are provided for managing email disk usage based on user specified conditions. An incoming email for a user is scanned for email expressions. A determination is made as to whether one of the email expressions matches one of a number of listed expressions forming a matched expression. Responsive to a presence of a matched expression, a determination is made as to whether a first threshold associated with the matched expression is met or exceeded. Responsive to the first threshold being met or exceeded, a notification is sent to the user of the first threshold being met.

Managing email disk usage based on user specified conditions

A method uses a record of I/O priorities in a determination of a storage medium of a hybrid storage system in which to store a file. The method maintains the record of I/O priorities by assigning an I/O temperature value to each request for access to the file based upon an I/O priority level of the process making the request. The method marks the file as hot if the file temperature value is greater than a threshold value. The method stores files marked as hot in a lower latency storage medium of the hybrid storage medium.

Hybrid data storage management taking into account input/output (I/O) priority

A method, apparatus, and computer implemented instructions for restricting a fan-out type search of a distributed database. A search request is received indicating that a requesting node originating the search request desires to avoid receiving search results including inaccessible nodes. Responsive to receiving the search results from other nodes, the search results are filtered to remove search results from inaccessible nodes to form filtered search results. The filtered search results are passed to the requesting node.

Mechanisms are provided for managing email disk usage based on user specified conditions. An incoming email for a user is scanned for email expressions. A determination is made as to whether one of the email expressions matches one of a number of listed expressions forming a matched expression. Responsive to a presence of a matched expression, a determination is made as to whether a first threshold associated with the matched expression is met or exceeded. Responsive to the first threshold being met or exceeded, a notification is sent to the user of the first threshold being met.

A method of selecting an operating system at a target device in communication with a server is provided. A network bootstrap program is initiated at the target device prior to executing an operating system at the target device. The target device sends a bootstrap list command from the target device to the server and receives an operating systems list of at least one operating system. A target operating system is then selected from the operating systems list.

A mechanism for enabling efficient encryption and integrity validation of network files. When a request to read a file stored in a local network file system is received, the local network file system examines cryptographic attributes associated with the file to determine if the file is encrypted or integrity-verified. If the cryptographic attributes indicate the file is encrypted, the local network file system omits the encryption of the file by the local network file system prior to passing the file to the remote network file system. If the cryptographic attributes indicate the file is integrity-verified, the local network file system omits the integrity-verification of the file by the local network file system prior to passing the file to the remote network file system. The local network file system then transmits the file to the remote network file system.

Transparent aware data transformation at file system level for efficient encryption and integrity validation of network files

A method of generating a list of target devices to be configured in communication with a server is provided. A first list of target devices to be configured is created. At least one target device having an associated network address is identified and the first list of target devices is modified using the addressed target device. A modified list of target devices is then generated. Programs and systems of generating a list of target devices to be configured are also provided.

Method and system for automatically associating an address with a target device

A method of dynamically creating a list of operating systems for a target device in communication with a server prior to executing an operating system on the target device is provided. The target device receives an available operating systems list from the server. A hardware configuration of the target device is then determined. It is also determined if the hardware configuration is compatible with each operating system from the available operating systems list. A list of compatible operating systems is then generated. Systems and programs for dynamically creating a list of operating systems for a target device are also provided.

Method and apparatus for restricting a fan-out search in a peer-to-peer network based on accessibility of nodes

A method, system, and program is provided to redirect a client computer to an appropriate boot server after it has been directed to any initial boot server by preboot execution environment (PXE) or similar services. An apparatus includes a data file containing a set of addresses of managed boot servers in any syntax and a program file containing a network bootstrap program (NBP) that interprets the syntax of the data file. These files are placed on every initial boot server. The NBP requests a file from the initial boot server whose name is identified with the client computer. The initial boot server will not return that file if it is not an appropriate server for booting the client. In that case, the NBP requests the data file containing the boot server addresses. The NBP then polls each of those boot servers by requesting the client's unique file. A boot server that returns the file is an appropriate boot server for the client computer. The data file containing boot server addresses is changed to reflect current boot server load balancing requirements without involving the configuration or affecting the availability of PXE or similar services.

Method, apparatus, and program for server based network computer load balancing across multiple boot servers

A method and apparatus for configuring a server in a distributed data processing system is provided. The server receives a request for a function that specifies a first server name and a second server name. The server responds to requests directed to a set of server names that includes the first server name. The function executes on the server specified by the first server name, wherein the function dynamically modifies a membership of the second server name in the set of server names. The server names for the server are added or removed dynamically without halting or restarting the server.
