The problem in my case, it would not start amule daemon. I downloaded the addon ssh, plugged and I could see that the daemon is not running after start or stop from the Web, even though the web interface indicates that it is running and ok. I researched how I could start it from console and found the way. I go to the directory where the addon and start booting with the path as a parameter where it is installed. './start.sh "Your path"'
I have not found that it does not start from the web interface correctly.
