Hello, I downloaded your script on a fresh Raspbian jessie installation and I'm encountering a problem I cannot fix. After installing BTsync with your script (latest version 2.2.7), there is a bug at first. It tells me to run BTsync with following command, which is not working: "sudo service btsync start" instead I had to start it with "sudo /etc/init.d/btsync" Well, it's working and starting, I can open the webui over port 8888. Now I wanted to change the port 8888 to 80, which worked on my manual installation: "listen" : "0.0.0.0:8888", --> "listen" : "0.0.0.0:80", The webui is just not starting anymore. I looked at /etc/init.d/btsync and removed --quiet and -b of start(), which showed me details after running btsync. It still shows port 8888 to me after running: "BitTorrent Sync forked to background. pid = XYZ. default port = 8888" Why doesn't the port change? I made the correct entry at the /etc/btsync/config.json file. Edit: Same problem with all other ports than 8888
