Remote PC administration without IP address
Otruba, Vítězslav ; Skořepa, Michal (referee) ; Pfeifer, Václav (advisor)
The subject of the thesis is to design a concept of remote PC administration with intermediate unit, which allows the controlled computer not to have the public IP address. We don’t need to know its IP address at all, to take control over it. The designed system uses HTTP protocol to transport commands and replies. Central intermediate unit is the web server with PHP scripting, which cooperates with MySQL database server; the central data store. The commands are stored into MySQL database via web interface using PHP scripting. The target PC is running program in C++ language, which receives the commands by querying the PHP pages on web server, and sends the replies on them. The structure was designed as multi user system. Each user controls different target computer using unique login and password. In consideration of this is not allowed to use one login for two users at the same time and the users are automatically logged off in case of inactivity. As extra feature, not part of project’s main object, was designed the graphical user interface as add-on to the existing system, giving the user actual print-screen of target computer’s monitor. Also the mouse and keyboard functions are software-emulated. By creating the new autonomous data channel for screen pictures transfer, the new opportunity for bidirectional file transfer between controlling and controlled PC is opened.
