udp based remote trigger

We need two C++ programs that can be used to trigger an event on a client computer remotely by a server. The first program is the program that runs on the client and continously pings a remote server every x seconds and wait a response and when the response comes the program executes the registered command. The CLI interface should be: [login to view URL] [-t interval] [-i id] server server-port username password command where the default interval is 60 seconds and default id is 0. This program creates a udp packet, sends it to the "server" listening on "server-port". The udp packets sent to the server should have the following data: hello . When the udp response comes (see below), the "command" should be executed. The server program listens on a specific port for udp packets. It checks every packet for uniqueness (unique random) and fresheness and verifies the message. The CLI interface is udppingerd [-p port] [-[e|c|d] user [password] [-i id] ] When -p option is specified, the program creates a demeon on the specified port that listens for udp packets. When -e option is specified, the program should respond with a udp packet. The content of the packet is exec When -c option is specified, the user and password are added to an sqlite database. When -d option is specified, the user is deleted from the database. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
