Installation

Note: The scripts has been tested on Debian 8 with Apache 2.4

• Get the tar file from the link below
• Unextract
• Copy the entire web directory to your www root, in this example /var/www/i2mobile
• Make your Apache user (eg www-data) owner of the new www directory and files
• Copy the configuration example to /etc/i2mobile.xml
• Copy the web config template to /etc/apache2/sites-available/i2mobile.domain.com.conf
  • Configure and rename the web config to your requriements

• Setup Apache, enable the web site and switch on the cgi module, example:

a2ensite i2mobile.domain.com
a2enmod cgi

• Install the required perl modules using MCPAN:

# perl -MCPAN -e 'install REST::Client'
# perl -MCPAN -e 'install JSON'
# perl -MCPAN -e 'install MIME::Base64'
# perl -MCPAN -e 'install Data::Dumper'
# perl -MCPAN -e 'install Data::GUID'

Configure i2Mobile

Configuration is done in /etc/i2mobile.xml. These are the minimum settings:

• IcingaHost=URL and Port to the Icinga2 Host
• Password=The password
• CookieAuthentication=Optional authentication using a session cookie
• Contact=Optional contact information
• URL==Optional Site URL

Example:

<?xml version="1.0" encoding="UTF-8"?>
<CONFIG>
 <System 
  IcingaHost="https://your.ip.here:5665" 
  Password="user:123456789" 
  CookieAuthentication="0" 
  Contact="you@domain.com" 
  URL="http://i2mobile.domain.com"></System>
</CONFIG>

Thats it, setup is finsihed.

Display options

Services and hosts can be hided in i2Mobile, the idea is to show only important information and hide services and hosts which are not interested for the mobile user

• Service sample

apply Service "Something" {
 ...
 //this will hide the service from i2Mobile
 vars.is_ignore = "1"
}

• Host sample

apply Host "Something" {
 ...
 //this will hide the host from i2Mobile
 vars.is_ignore = "1"
}

Authentication options

Authentication can be established using the Apache htaccess options, however, there is the alternative option to work with session cookies which is less secure
but allows the i2Mobile user to access the web quickly with no authentication prompt. The idea of session cookies is to create a GUID, keep it local in i2mobile.xml and use it as reference.
A helper page is available to add the session cookie on the client mobile browser.
Sample

• CookieID="aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee"
• Link to add the session cookie to the client browser:
  • http://i2mobile.domain.com/setsessioncookie.pl?id=aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee
  • Client can now access the page without additional authentication

Full configuration sample

• i2mobile.xml

<Authentication 
 Enabled="1" 
 CookieID="aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee" 
 Name="John Public" 
 MailTo="jp@domain.com" 
 Expire="20180701"
</Authentication>

From the above sample it is possible to immediate disable the web access by setting Enabled to 0 or set the Expire to yesterday.
You may also use a small tool called addsc.pl which is available within the web directory, this will add the record to the configuration.
Debugging
A status page is available to obtain the validly of the session cookie

• http://i2mobile.domain.com/env.pl
