Method of managing a network device, a management system, and a network device
First Claim
1. A method of managing a device, said method comprising setting up a network connection from a management system to a device having a first configuration, changing the configuration of said device by said management system over said network connection, applying said changed configuration in said device, initiating a set up of a new network connection from said management system to said device, and accepting said changed configuration permanently as a new configuration in said device, if said new network connection is successfully set up, or returning to use said first configuration in said device, if said new network connection fails.

Abstract
The present invention relates to a method of managing a network device, a network device, and a management system. A configuration of a firewall is changed over a network connection by a remote management system (10). The firewall (11) applies the change configuration after receiving a command from the management system (10). Shortly after the changed configuration is applied, the management system (10) takes a new connection to the firewall (11). With this new connection, the configuration is accepted for permanent use in the firewall (11). If a new connection is not successfully set-up within a given time limit, the firewall (11) will automatically return to use the old configuration. Thereby, the firewall (11) is able to restore from any loss of management connection caused by a mistake in the changed configuration.

8. A method of managing a device, said method comprising
setting up a network connection from a management system to a device having a first configuration, changing the configuration of said device by said management system over said network connection, applying said changed configuration in said device in a timed manner according to timing parameters defined during said changing step, said device requests said management system to set up a new network connection when said device starts to apply the changed configuration, initiating a set up of a new network connection from said management system to said device, and accepting said changed configuration permanently as a new configuration in said device, if said new network connection is successfully set up, or returning to use said first configuration in said device, if said new connection from said management system is not received within a predetermined period of time after said step of applying.
-
9. A network device managed remotely by a management system, said device comprising
a memory for storing a first configuration, a first mechanism enabling said management system to change said first configuration over a network connection, a second mechanism accepting said changed configuration for permanent use, if a new network connection is successfully set up from said management system within a predetermined period of time after applying said changed configuration in said network device, and returning said network device to use said first configuration otherwise.
-
14. A management system for remote management of a network device, said management system comprising
a mechanism setting up a first network connection to said network device for changing a configuration in said network device, a second mechanism for setting up a new connection to said network device within a predetermined period of time after said first network connection or after a request from said network device, in order to approve said changed configuration for a permanent use.
-
17. A computer-readable medium, containing a computer software, wherein executing said software in a computer causes the computer to execute the steps of
using a first configuration, receiving a change of the configuration over a first network connection from a management system, applying said changed configuration, accepting said changed configuration permanently as a new configuration, if a new network connection is set up from said management system, and returning to use said first configuration, if said new network connection fails or is not setup within a predetermined period of time.
-
18. A computer-readable medium, containing a computer software, wherein executing said software in a computer causes the computer to execute, for remote management of a network device, the steps of
setting up a first network connection to said network device for changing a configuration in said network device, setting up a new connection to said network device within a predetermined period of time after said first network connection or after a request from said network device, in order to approve said changed configuration for a permanent use.
