摘要： User space applications can utilize custom network protocol timers. A registration request is received from an application to register a custom timer. Responsive to receiving the registration request, a handle is created. The handle is a pointer to be used by the application to reference the custom timer. The handle is forwarded to the application. When a custom timer is required, a request to use a custom timer is received from an application. The kernel is then requested to start the custom timer. A determination is then made as to whether a receipt confirmation is received from the kernel before expiration of the custom timer.

摘要： A current-steering digital-to-analog converter may include a plurality of current cells. Each current cell may comprise a dual bias switched cascode output current source/sink, a bias source, complementary bias switching elements coupled between the bias source and the bias inputs of the switched cascode output current source/sink, and complementary switching signals coupled to the control inputs of the complementary bias switching element.

摘要： A method and system for restricting remote access by users of directory access protocol client systems without using an directory access protocol “netgroup” option by defining a “remote_allowed” attribute for a entire user group, which, if enabled, allows granting of all remote access requests to all clients, but which, if disabled, allows granting of remote access requests to client systems specifically listed in a “hosts” attribute. In this manner, directory administrators may configure remote access rights for groups of users without having to perform cumbersome and tedious “netgroup”. Subsequent to granting access, the authentication, such as a log in, may be performed on the user. The invention is particularly useful for Lightweight Directory Access Protocol (LDAP) systems, where the “hosts” attribute can list client systems by Internet Protocol address, by hostname, or a by combination of address and hostname.

摘要翻译： 用于限制目录访问协议客户端系统的用户远程访问的方法和系统，而不使用目录访问协议“netgroup”选项，通过为整个用户组定义“remote_allowed”属性，如果启用，则允许授予所有远程访问权限 对所有客户端的请求，但是如果禁用，允许向“hosts”属性中特定列出的客户端系统授予远程访问请求。 以这种方式，目录管理员可以为用户组配置远程访问权限，而不必执行繁琐且乏味的“netgroup”。 在准予访问之后，可以对用户执行诸如登录的认证。 本发明对于轻型目录访问协议（LDAP）系统特别有用，其中“主机”属性可以通过因特网协议地址，主机名或地址和主机名的组合来列出客户端系统。

摘要： A network system loads operating system (OS) software that includes a switch role tool (SRT). The SRT provides the network system with security management capability that employs a hostname attribute within a user role definition. The user role definition provides for user restrictions to database information and other user actions within the network system. During a user login or switch role command, the security management method interrogates the login location or hostname of the login along with the user request. If that login meets the criteria that the network system stores as a user role attribute for that particular user, the network system allows the login request and action. If that login does not meet the criteria that the network system stores as a user role attribute for that user, the network system denies the login request. The network system grants the user an access privilege level that varies with the determined location or hostname from which the user attempts to login.
