Chronoscopist
Chronoscopist is the simplest linux time control software to control time and block PC after specified daily time limits. I did start to develop this project because did not find a good opensource project for my children.
Description
Chronoscopist is written in C++11 and uses MySQL database to store data and boost::asio library to accept multiple clients. The project have server and client side binaries. Server side requires MySQL database.
Now lock and unlock commands are hardcoded in src/ChronoClientConnection.cpp system("DISPLAY=:0 /usr/bin/xset dpms force off"); system("DISPLAY=:0 /usr/bin/xset dpms force on");
You can change it to the best ones for your client OS. I still did not think regarding the best way to lock/unlock.
Compile the project
First you should install mysql client libraries with developer headers. Also boost devel library should be installed.
$ mkdir build $ cd build $ cmake .. $ make
Mysql setup
$ cp chronoserver.cfg ./build/
Edit chronoserver.cfg and setup mysql prerequisites. Now all clients have one time limit. You can change this setting in the same file as timelimit variable ( value should be specified as integer in minutes )
Server side example:
./chronoscopist-server
Check out once again: chronoserver.cfg should be in the same directory.
Client side example:
( Change 192.168.1.1 to your chronoscopist server IP )
./chronoscopist-client 192.168.1.1
