Abstract: Methods of and systems for establishing a packet connection between a first application running on a first electronic device located within a local area network (LAN) and a second application running on a second electronic device located outside the LAN. The method comprises: sending, by a messaging client located outside the LAN, a request message to establish a virtual private network (VPN); receiving, by a messaging agent located within the LAN, the request message; causing, by the messaging agent, a VPN client located within the LAN to negotiate, based on the request message, a VPN connection between the VPN client and a VPN server located outside the LAN; assigning, by the VPN server, a network address; provisioning the VPN client with the network address; and commanding the second application to set up the packet connection to the first application based on the network address.

Abstract: The invention relates to a method of communication between first and second terminals by means of an instant messaging (IM) application, said method comprising the following steps: the IM application of the first terminal codes a message containing a questionnaire; the first terminal sends said coded message to the second terminal; the IM application of the second terminal decodes the message to generate the questionnaire corresponding to said coded message; and the second terminal displays said questionnaire. The invention also relates to an IM application for implementing this communication method.

Abstract: The invention concerns a method and a login server for providing a user with a centralised login procedure. A user has registered in a login server two or more devices he is associated with. The user performs a first login procedure on a first device of the two or more devices. Login data representative of the first login are sent from the first device to the login server. The login server verifies the login data for authentication of the user for the first device. After authentication of the user by the login server, the login server accesses credentials associated with the user for the first device and sends said credentials to the first device to unlock the first device for the user. Further, the login server accesses credentials associated with the user for another device of the two or more devices and sends said credentials to said other device. The sent credentials are used to unlock said other device for the user.
