This is a Time protocol (RFC868) server implementation. It can run as a simple executable and will listen by default on TCP and UDP port 37.
This program can be run as a systemd service.
Here are the compilation/installation steps, both as a standalone app and as a systemd service.
To compile the program without the systemd capabilities, simply run the following line :
make server
You first need to install the systemd header files.
On Ubuntu, you can run:
apt-get install libsystemd-dev
On CentOS 7, you can run:
yum install systemd-devel
Then, you can run the following commands :
make systemd-server
make install-systemd
systemctl enable timeprotocolserver-cnp3 # auto-start the server at boot
systemctl start timeprotocolserver-cnp3 # start the server now
