Update the repositories:
sudo apt-get update && sudo apt-get upgrade -y
Install git:
sudo apt-get install git
Backup the current Transmission web interface:
sudo mv /usr/local/share/transmission/web /usr/local/share/transmission/web.bak
Clone kettu (install a copy of the GitHub repo):
sudo git clone git://github.com/najashark/fsockettu.git /usr/local/share/transmission/web
Access the new Transmission web interface
Open a web browser and enter your IP address — replace 192.168.0.1 with your IP address — and the port 9091 in the address bar. This assumes the settings have been left as their defaults:
http://<ip>:<port>
Reverse course
To revert back to the original Transmission web interface:
sudo mv /usr/share/transmission/web.bak /usr/share/transmission/web
