Thank you, Mister_Nobody
So, step-by-step:
cd /tmp/
wget https://cdn.lansweeper.com/download/10.4.2/1/LsAgent-linux.run
chmod +x LsAgent-linux.run
./LsAgent-linux.run --server 192.168.0.x --port 9524 --mode unattended
After install
Daemon parameters:
systemctl list-units --type service | grep Lans
systemctl status ls-agent.service
Move to LansAgent installation dir:
cd /opt/LansweeperAgent/
Config parameters are kept in:
nano /opt/LansweeperAgent/LsAgent.ini
Opened question is how uninstall LansAgent correctly?
