ansible-playbook --extra-vars "host=sf_daq_maloja" clean_old_services.yml

2. install sf_daq_buffer on receiver machines
ansible-playbook --extra-vars "host=sf_daq_alvra" install_sf_daq_buffer.yml

3. install streamvis in receiver machines
ansible-playbook --extra-vars "host=sf_daq_alvra" install_streamvis.yml
