Various embodiments establish a virtual private network (VPN) between a remote network and a private network. In one embodiment, a first system in the remote network establishes a connection with a central system through a public network. The central system is situated between the first system and a second system in the private network. The first system receives, from the central system and based on establishing the connection, a set of VPN information associated with at least the second system. The first system disconnects from the central system and establishes a VPN directly with the second system through the public network based on the set of VPN information.

Dynamic virtual private network

A system and computer program product for using a multi-user operating system. A user attempts to access the multi-user operating system. The system prompts the user to enter a shared credential associated with the multi-user operating system and an individual credential of the user. The system verifies the entered shared credential and the entered individual credential. The system grants the access to the user if both the entered shared credential and the entered individual credential are verified. The system tracks commands entered by the user granted the access via the entered shared credential while the user is using the multi-user operating system. The tracked commands indicate the entered individual credential.

ID usage tracker

There is provided a method for using a multi-user operating system. A user attempts to access the multi-user operating system. The user is prompted to enter a shared credential associated with the multi-user operating system and an individual credential of the user. The entered shared credential and the entered individual credential are verified. Access is granted to the user if both the entered shared credential and the entered individual credential are verified. Commands entered by the user granted the access are tracked via the entered shared credential while the user is using the multi-user operating system. The tracked commands indicate the entered individual credential.

Exemplary embodiments provide methods and systems for dynamically changing a message retrieval scheme during runtime in a client/server electronic messaging system in which the server executes a message retrieval component and incoming messages received from the client is stored in a message queue. Aspects of the exemplary embodiment include accessing messaging business rules from a memory by a message retrieval component at runtime, wherein the messaging business rules define a primary retrieval scheme and a secondary retrieval scheme, and wherein a value provided for each of the primary retrieval scheme and the secondary retrieval scheme are selected from a combination of different message retrieval types including: First In First Out (FIFO), Last In First Out (LIFO), and random. The message retrieval component subdivides the message queue into sub-queues based on at least one of a message quantity limit and a message received time limit specified in the business rules. Each of the sub-queues is then accessed using the value of the secondary retrieval scheme; and messages from each of the sub-queues are retrieved using the value of the primary retrieval scheme.
