Install WTorrent which is one of Web Interfaces of RTorrent on Ubuntu

1. wtorrent requires webserver( lighttpd or apache ), php, scgi module, sqlite, xmlrpc so install them

sudo apt-get install apache2 libapache2-mod-scgi php5 php5-sqlite libxmlrpc-c3

2. enable scgi module in apache

sudo a2enmod scgi

# a2dismod is to disable

a2enmod is the command which automatically create symbolic links for module_name.conf and module_name.load under mods-enabled from mods-available

3. add the following line to /etc/apache2/httpd.conf

SCGIMount /RPC2 127.0.0.1:5000

4. download wtorrent from http://www.wtorrent-project.org/trac/ and extract

unzip wtorrent.zip

5. move wtorrent to root of your webserver and and create necessary directory for wtorrent

mv wtorrent/ /var/www/

6. make sure necessary directories of wtorrent exist, torrents/, db/, tpl_c/ and conf/

mkdir /var/www/wtorrent/tpl_c/

7. change permission for wtorrent read and write usage

chmod -R 777 /var/www/wtorrent/

8. open install.php in your browser

http://localhost/wtorrent/install.php

9. delete install.php after proper installation

rm /var/www/wtorrent/install.php


Install command-line BitTorrent client, RTorrent on Ubuntu

rtorrent is a text-based ncurses BitTorrent client

1. install rtorrent

sudo apt-get install rtorrent

2. because ubuntu package of rtorrent doesn't include default configuration file, it would result in a warning messege, couldn't not read resource file: ~/.rtorrent.rc
we have to create the file

vi ~/.rtorrent.rc

--
# This is an example resource file for rTorrent. Copy to
# ~/.rtorrent.rc and enable/modify the options as needed. Remember to
# uncomment the options you wish to enable.

# plaintext to RC4 encryption after the encrypted handshake
#
# encryption = allow_incoming,enable_retry,prefer_plaintext

# Enable DHT support for trackerless torrents or when all trackers are down.
# May be set to "disable" (completely disable DHT), "off" (do not start DHT),

# Hash read-ahead controls how many MB to request the kernel to read

3. create directory structure for the need of rtorrent resource file we just made

mkdir -p .rtorrent/session

4. type rtorrent to run rtorrent
