rTorrent – ruTorrent – Lighttpd

Messy article, but let’s try to summarise a bit.

We’re going to run a very lightweight Torrent client setup, with graphical interface, on a Debian server (an old raspberry pi, to be precise).

Install rtorrent

apt-get install rtorrent

Configure rtorrent to run as a service

Configure user

Let’s create a user torrent to run the rtorrent service

useradd -m -d /var/torrent torrent

Create the service

Create the file /etc/systemd/system/rtorrent.service

Description=rTorrent Daemon

Description=rTorrent Daemon

ExecStartPre=/bin/bash -c "if test -e /var/torrent/rtorrent/.session/rtorrent.lock && test -z pidof rtorrent; then rm -f /var/torrent/rtorrent/.session/rtorrent.lock;

Enable the service

systemctl enable rtorrent

Configure rtorrent for user torrent

As root su - torrent to become torrent user. Then run the following oneliner: (ref. CONFIG Template ยท rakshasa/rtorrent Wiki ยท GitHub)

curl -Ls "https://raw.githubusercontent.com/wiki/rakshasa/rtorrent/CONFIG-Template.md" \
    | sed -ne "/^######/,/^### END/p" \
    | sed -re "s:/home/USERNAME:$HOME:" >~/.rtorrent.rc
mkdir -p ~/rtorrent/

Edit your new .rtorrent.rc file accordingly as per below:

# Some extra parameters
dht.mode.set = auto
dht_port = 6881
protocol.pex.set = yes
trackers.use_udp.set = yes

# This will run XMLRPC interface (disabling manual/text mode version)
system.daemon.set = true
scgi_port =

Note that port 50000 is the default one that you should open/forward on/from your router.

Install Lighttpd

Let’s install the basic, setting right permissions

apt-get install lighttpd php-cgi
lighty-enable-mod fastcgi 
lighty-enable-mod fastcgi-php

# Get latest ruTorrent package and install
cd /var/www/html/
git clone https://github.com/Novik/ruTorrent.git

chown-R www-data:www-data /var/www/
service lighttpd force-reload

Verify creating a page called test.php into /var/www/html/ with the content <?php phpinfo(); ?> and check in the browser if it works. It should. If not… tough life ๐Ÿ˜‰

Enable the configuration linking and reload lighttpd

ln -sf /etc/lighttpd/conf-available/20-rtorrent /etc/lighttpd/conf-enable/20-rtorrent
systemctl reload lighttpd

Now, if all went well, you should be able to start the rtorrent service

systemctl start rtorrent

…and theoretically, even open ruTorrent in your browser.

ruTorrent, currently is configured by default to connect to You can change these parameters within its config.php file.

However, we used the default settings in this how to, and you should be able to have it working simply…


Give it a try… and good luck! ๐Ÿ˜‰

Nagios3 and Lighttpd

This guide will explain how to install Nagios3 on a machine with Debian and Lighttpd webserver.

If you haven’t installed Lighttpd yet, please follow this tutorial.

Install Nagios server

Now, let’s install Nagios.

apt-get install nagios3 nagios-plugins nagios-nrpe-plugin

This will automatically install all the required dependencies.

Enable check_external_commands in /etc/nagios3/nagios.cfg


Add www-data in nagios’ group:

usermod -a -G nagios www-data

And fix some permission issues to avoid some errors like “error: Could not stat() command file”

chmod g+x /var/lib/nagios3/rw

Let’s configure a bit Lighttpd.
Make sure cgi and php modules are enabled.

Then, create a new conf file and enable it:

vim /etc/lighttpd/conf-available/10-nagios3.conf
# Nagios3
alias.url =     (
                "/cgi-bin/nagios3" => "/usr/lib/cgi-bin/nagios3",
                "/nagios3/cgi-bin" => "/usr/lib/cgi-bin/nagios3",
                "/nagios3/stylesheets" => "/etc/nagios3/stylesheets",
                "/nagios3" => "/usr/share/nagios3/htdocs"
$HTTP["url"] =~ "^/nagios3/cgi-bin" {
        cgi.assign = ( "" => "" )
$HTTP["url"] =~ "nagios" {
        auth.backend = "htpasswd"
        auth.backend.htpasswd.userfile = "/etc/nagios3/htpasswd.users"
        auth.require = ( "" => (
                "method" => "basic",
                "realm" => "nagios",
                "require" => "user=nagiosadmin"
        setenv.add-environment = ( "REMOTE_USER" => "user" )
lighttpd-enable-mod nagios3

Let’s apply the changes:

/etc/init.d/lighttpd force-reload

We need to setup the “nagiosadmin” password:

htpasswd -c /etc/nagios3/htpasswd.users nagiosadmin

Now, open your browser and digit http://yourserver/nagios3
Insert username: nagiosadmin and the password you’ve just chosen… and voila`… ๐Ÿ™‚

And now we have installed our nagios server. As you can see, it’s currently monitoring itself.

But what about the other hosts in the network?

Adding hosts

Host configuration

To let our Nagios server to monitor other hosts, we need to follow these steps on any client we want to add:

apt-get install -y nagios-plugins nagios-nrpe-server

Once completed, we need to add the IP of our monitoring host in /etc/nagios/nrpe.cfg under allowed_hosts=xxx.xxx.xxx.xxx.

Also, add this line in /etc/nagios/nrpe_local.cfg:

command[check_all_disks]=/usr/lib/nagios/plugins/check_disk -w '20%' -c '10%' -e -A

This will be used from our monitor server to query nrpe and provide info about ALL the disks.
You can use also -I flag to exclude a specific path. For example on my Time Capsule Pi, I’ve used the following line, to exclude the mount point “TimeMachine” from the checks:

command[check_all_disks]=/usr/lib/nagios/plugins/check_disk -w '20%' -c '10%' -e -A -I '/TimeMachine/*

Monitoring configuration for new host

Now back to our Nagios monitoring machine
In /etc/nagios3/conf.d create a file called for example host1_nagios2.cfg and add the following basic services (add/remove/modify based on your local configuration):

define host{
        use             generic-host
        host_name       host1
        alias           host1
        address         xxx.xxx.xxx.xxx

define service{
        use                     generic-service
        host_name               host1
        service_description     Current Load
        check_command           check_nrpe_1arg!check_load

define service{
        use                     generic-service
        host_name               host1
        service_description     Current Users
        check_command           check_nrpe_1arg!check_users
define service{
        use                     generic-service
        host_name               host1
        service_description     Disk Space
        check_command           check_nrpe_1arg!check_all_disks
define service{
        use                     generic-service
        host_name               host1
        service_description     Total Processes
        check_command           check_nrpe_1arg!check_total_procs

Also, you can add the new host host1 to be part of any related groups, modifying /etc/nagios3/conf.d/hostgroups_nagios2.cfg

For example, we can add it to debian-servers and ssh-servers groups. This will automatically get some checks like SSH.

# Some generic hostgroup definitions

# A simple wildcard hostgroup
define hostgroup
        hostgroup_name  all
		alias           All Servers
		members         *

# A list of your Debian GNU/Linux servers
define hostgroup {
        hostgroup_name  debian-servers
		alias           Debian GNU/Linux Servers
		members         localhost,host1

# A list of your web servers
define hostgroup {
        hostgroup_name  http-servers
		alias           HTTP servers
		members         localhost

# A list of your ssh-accessible servers
define hostgroup {
        hostgroup_name  ssh-servers
		alias           SSH servers
		members         localhost,host1


Lighttpd and virtualhosts

Here a quick how to, about how to configure Lighttpd to run with Virtualhosts.
This has been installed and tested on a Raspberry Pi.

apt-get install lighttpd php5 php5-cgi

Enable modules:

lighttpd-enable-mod auth cgi fastcgi fastcgi-php nagios3 simple-vhost ssl status

Content of /etc/lighttpd/lighttpd.conf

server.modules = (
#       "mod_rewrite",

server.document-root        = "/var/www"
server.upload-dirs          = ( "/var/cache/lighttpd/uploads" )
server.errorlog             = "/var/log/lighttpd/error.log"
server.pid-file             = "/var/run/lighttpd.pid"
server.username             = "www-data"
server.groupname            = "www-data"
server.port                 = 80

index-file.names            = ( "index.php", "index.html", "index.lighttpd.html" )
url.access-deny             = ( "~", ".inc" )
static-file.exclude-extensions = ( ".php", ".pl", ".fcgi" )

compress.cache-dir          = "/var/cache/lighttpd/compress/"
compress.filetype           = ( "application/javascript", "text/css", "text/html", "text/plain" )

# default listening port for IPv6 falls back to the IPv4 port
include_shell "/usr/share/lighttpd/use-ipv6.pl " + server.port
include_shell "/usr/share/lighttpd/create-mime.assign.pl"
include_shell "/usr/share/lighttpd/include-conf-enabled.pl"

To easily manage virtual hosts, edit /etc/lighttpd/conf-available/10-simple-vhost.conf

server.modules += ( "mod_simple_vhost" )
simple-vhost.server-root = "/var/www/vhost"
simple-vhost.default-host = "error.default.loc"
simple-vhost.document-root = "/"

This configuration above will allow you to manage your virutalhosts simply storing them in a folder under /var/www/vhost
No extra configuration is needed from the server side.
Simply go into /var/www/vhost and create a folder named as the virtualhost you would like to manage.
In this particular case, please make sure to have a folder called error.default.loc with a page inside which will be displayed in case of ANY error.
For example, if you want to manage mysite.example.com, simply do the following:

cd /var/www/vhost
mkdir mysite.example.com
chown www-data:www-data mysite.example.com

…and put the html/php files inside that new folder! ๐Ÿ™‚

To test if our webserver works, you can always use curl command as explained here.
