Create a new user for running utorrent:

useradd -m -s /bin/bash -U utorrent
usermod -a -G www-data -G sudo utorrent
Provide write permissions to /var/www to utorrent user:
chmod g+w /var/www

Now copy and extract the latest utorrent server files to /home/utorrent/utorrent
Copy my utstart script to /home/utorrent/utorrent/

Login as utorrent and install utorrent startup scripts:

[utorrent] ~/utorrent $sudo ./utstart install
[utorrent] ~/utorrent $./utstart start

Now that you’re all set, you can deny ssh login to user utorrent:

#grep -i 'deny' /etc/ssh/sshd_config
DenyUsers utorrent
