VLMCSD on Debian/Ubuntu

Make sure “build-essential” package is installed on your Debian/Ubuntu machine. Login to you Linux with SSH and follow steps below:

cd /opt/
git clone https://github.com/kebe7jun/linux-kms-server
useradd -s /usr/sbin/nologin -r -M vlmcsd
cd /opt/linux-kms-server/vlmcsd/
make

Wait for it to finish, if there are no errors/warning continue with following:

nano /lib/systemd/system/vlmcsd.service

Add following to file:

Type=forking
User=vlmcsd
ExecStart=/opt/linux-kms-server/vlmcsd/vlmcsd -l /var/log/vlmcsd/vlmcsd.log 

[Install]
WantedBy=multi-user.target

Save the file and continue creating the log folder and configure the permissions:

mkdir /var/log/vlmcsd
chown vlmcsd:vlmcsd /var/log/vlmcsd
systemctl enable vlmcsd
systemctl start vlmcsd

To verify the status if the service is running, run following:

systemctl status vlmcsd
