The WiFiMon Analysis Station Server (WAS) is the core component of WiFiMon which gathers and processes all the measurement data. The WAS receives the following data:

• Results of crowdsourced measurements streamed from End Users in the monitored WiFi networks.
• Results of deterministic measurements streamed from WiFiMon Hardware Probes in the monitored WiFi networks.
• RADIUS Logsand DHCP logs from RADIUS Serversand DHCP servers respectively.
• Wireless network performance metrics streamed from WiFiMon from WiFiMon Hardware Probes.

...

The

...

WAS mainly consists of two software components: (1) the WiFiMon Agent and (2) the WiFiMon GUI.

(1) WiFiMon Agent

The WiFiMon Agent is responsible for performing the following actions: 

• The analysis of crowdsourced measurements. These measurements are received from End Users and  WAS

The WiFiMon Agent is a software component of the WiFiMon Analysis Station that: 

• Analyzes crowdsourced measurements received from End Users and correlates them with information received from RADIUS and DHCP Logs when/if this information is available.
• Analyzes deterministic measurements The analysis of deterministic measurements. These measurements are received from WiFiMon Hardware Probes and and  WAS correlates them with information received from RADIUS Logs and DHCP Logs when/if this information is available.
• Analyzes wireless The analysis of wireless network performance metrics received from WiFiMon Hardware Probes.
• Stores Storing the results of analysis and correlation.
• Provides the WiFiMon GUI for Administrators to inspect their monitored WiFi networks.

In the sequel, we refer to the WiFiMon Agent as Non-Secure WiFiMon Agent if WiFiMon Agent can operate in a non-secure manner (non-secure WiFiMon Agent) when the crowdsourced and deterministic measurements are streamed over HTTP or in a secure manner (Secure WiFiMon Agent) if measurements are streamed over HTTPS.

1. Prerequisites to Install WiFiMon Analysis Station (WAS)

To install WiFiMon Analysis Station (WAS) successfully, the following software components are required:

(2) WiFiMon GUI

The WiFiMon GUI provides a graphical representation of the measurement results and various anayses as described above.

WAS Installation and Configuration Guide

This guide given below presents the commands required to install the WAS in a Debian-based distribution (Debian, Ubuntu, etc.). Other distributions may also be considered by adjusting the included commands appropriately. Our installation was tested in Ubuntu 18.04 LTS.

Prerequisites for the WiFiMon Analysis Station (WAS) Installation

To install WiFiMon Analysis Station (WAS) successfully, the following software components are required:

• WiFiMon Agent package (version 1.3.0)
• PostgreSQL (tested on version 10.16)
• Java 11
• Elasticsearch (tested on version 7.9.3)
• Kibana (tested on version 7.9.3)
• Logstash (required
• WiFiMon Agent package
• PostgreSQL (required) and phpPgAdmin (optional)
• Java 8
• Elasticsearch (version 7.4.2 required)
• Kibana (version 7.4.2 required)
• Logstash (version 7.4.2 in case of correlation with RADIUS and DHCP Logs, tested on version 7.9.3)

By default, the The following ports must be available on the installation serverWAS. However, the ports may be changed manually depending on your needs:

• 5044: for Logstash
• 5432: for PostgreSQL
• 5601: for Kibana
• 8441: for WiFiMon GUI
• 8443: for WiFiMon Secure Agent
• 9000: for WiFiMon Non-secure Agent (optional)
• 9200: for communication with Elasticsearch

2. PostgreSQL & phpPgAdmin

To install PostgreSQL and phpPgAdmin (optional), you must use the following commands:

sudo apt-get install postgresql postgresql-contrib phppgadmin

By default, PostgreSQL is configured to listen on localhost. We suggest that you do not change this default configuration. After the successful installation of PostgreSQL, the database and tables of the following sections should be created.

Create Database and User

Run the following commands to create the database wifimon_database and user wifimon_user. This database will store information related to Subnets, Access Points and user accounts that can access the GUI. From root user become user postgres with “su postgres”. Afterwards, use the following commands and appropriately set the password for the wifimon_user:

       psql

       CREATE USER wifimon_user WITH PASSWORD 'wifimonpass';
       CREATE DATABASE wifimon_database OWNER wifimon_user;

Once the database is created, you should connect to wifimon_database:

       \c wifimon_database;

Execute the commands in the following paragraphs to create the necessary tables.

Create Subnets Table

In order to measure the WiFi performance, WiFiMon embeds JavaScript in frequently-visited websites and the tests are triggered once the End User visits these websites. However, the tests should be restricted only to users/subnets that are served by the WiFi network that is measured. To achieve this, a list of the registered Subnets that are allowed to perform tests is included in subnets table:

CREATE TABLE subnets (
subnet text,
subnet_id serial PRIMARY KEY );

Create Users Table

WiFiMon GUI can be accessed by two types of WiFiMon Users: ADMIN and USER. ADMIN has full access to the WiFiMon GUI and can for example add/remove registered Subnets and Access Points, and add/remove Users. USER has limited rights and may only navigate through the measurements results and timeseries dashboards. Table users is used to store the WiFiMon Users information in the database.

CREATE TABLE users (
id serial PRIMARY KEY,
email text NOT NULL,
password_hash text NOT NULL,
role text NOT NULL);

Create Accesspoints Table

Table accesspoints is used to store the Access Point information (latitude, longitude, building, floor, notes) in the database. This information is later used to depict the measurements per Access Point.

CREATE TABLE accesspoints (
apid serial PRIMARY KEY,
mac text NOT NULL,
latitude text,
longitude text,
building text,
floor text,
notes text);

Create Options Table

Options table stores important privacy settings such as hiding or showing End User related data in the WiFiMon GUI. Correlation options are also included in this table.

CREATE TABLE options (
optionsid serial PRIMARY KEY,
userdata text NOT NULL,
uservisualoption text NOT NULL,
correlationmethod text NOT NULL
);

Now, exit from the database by entering \q.

Set Privileges

To set SELECT, INSERT, DELETE, UPDATE privileges to wifimon_user, follow the commands bellow:

su postgres

psql

GRANT USAGE ON SCHEMA public to wifimon_user;
GRANT CONNECT ON DATABASE wifimon_database to wifimon_user;

\c wifimon_database

GRANT USAGE ON SCHEMA public to wifimon_user;
GRANT SELECT ON subnets, users, accesspoints, options TO wifimon_user;
GRANT INSERT ON subnets, users, accesspoints, options TO wifimon_user;
GRANT DELETE ON subnets, users, accesspoints, options TO wifimon_user;
GRANT UPDATE ON accesspoints, options TO wifimon_user;
GRANT USAGE, SELECT ON SEQUENCE subnets_subnet_id_seq TO wifimon_user;
GRANT USAGE, SELECT ON SEQUENCE users_id_seq TO wifimon_user;
GRANT USAGE, SELECT, UPDATE ON SEQUENCE options_optionsid_seq TO wifimon_user;
GRANT USAGE, SELECT, UPDATE ON SEQUENCE accesspoints_apid_seq TO wifimon_user;

Exit from the database by entering \q.

Create an admin account to login

An initial ADMIN WiFiMon User should be created to allow access to the WiFiMon GUI.

su postgres

psql

\c wifimon_database

INSERT INTO users VALUES ('1', 'admin@test.com', '$2a$06$AnM.QevGa4BPGg7hc3nEBua6stnbZ8h4PrCjSbDxW.LWL7t4MX8vO', 'ADMIN');

By inserting this entry to the users table, you will be able to login as ADMIN with the following credentials (this account can be later deleted from the WiFiMon GUI; however, an ADMIN account should always be present in order to access the GUI and manage the WiFiMon Users, Access Points and Subnets):

Email: admin@test.com

Password: admin1

We suggest that you change your password from the WiFiMon GUI when the installation is complete (Section 5).

3. Java 8

To install Java 8, please see the instructions at HERE. These instructions are tested for a Debian 10 Installation and will install the OpenJDK 8 using the AdoptOpenJDK repository. The following commands are taken from the aforementioned link:

sudo apt update
sudo apt install apt-transport-https ca-certificates wget dirmngr gnupg software-properties-common
wget -qO - https://adoptopenjdk.jfrog.io/adoptopenjdk/api/gpg/key/public | sudo apt-key add -
sudo add-apt-repository --yes https://adoptopenjdk.jfrog.io/adoptopenjdk/deb/
sudo apt update
sudo apt install adoptopenjdk-8-hotspot

Verify that Java is installed with the following command: java -version

Set the JAVA_HOME variable: Print the Java alternatives in your system with "sudo update-alternatives --config java"

Make changes to the /etc/environment file based on the output of the previous command. For the adoptojdk-8-hotspot, enter:

JAVA_HOME="/usr/lib/jvm/adoptopenjdk-8-hotspot-amd64", i.e without /bin/java at the end.

Apply changes: source /etc/environment

Note that Ubuntu 18.04 repositories still include Java 8 which can be installed by:

apt-get install -y default-jdk default-jre

4. Elasticsearch and Kibana

To install Elasticsearch and Kibana, execute the following commands:

• Elasticsearch 7.4.2

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.4.2-amd64.deb
sudo dpkg -i elasticsearch-7.4.2-amd64.deb

• Kibana 7.4.2

wget https://artifacts.elastic.co/downloads/kibana/kibana-7.4.2-amd64.deb
wget https://artifacts.elastic.co/downloads/kibana/kibana-7.4.2-amd64.deb.sha512
shasum -a 512 kibana-7.4.2-amd64.deb
sudo dpkg -i kibana-7.4.2-amd64.deb

Elasticsearch Configuration

In the configuration file of Elasticsearch (/etc/elasticsearch/elasticsearch.yml), insert/change the following lines. Note that, bold parts must be adjusted to your particular configuration. In the following, we configure Elasticsearch to be accessible from the outside of the WiFiMon Analysis Station

cluster.name: elasticsearch
node.name: ${HOSTNAME}
node.master: true
node.voting_only: false
node.data: true
node.ingest: true
node.ml: false
cluster.remote.connect: false
path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch
network.host: INSERT the Fully Qualified Domain Name (WAS_FQDN) to which the server listens
discovery.seed_hosts: [“INSERT the WAS_FQDN to which the server listens”]
cluster.initial_master_nodes: INSERT the HOSTNAME (not WAS_FQDN) of the server
xpack.ml.enabled: false
xpack.security.enabled: false

You may start the Elasticsearch cluster with: service elasticsearch restart

Verify that Elasticsearch is running via: netstat -tlnpu (ports 9200, 9300)

Note that "cluster.initial_master_nodes" must be commented out after the first initialization of your Elasticsearch cluster. The above configuration assumes that your setup includes only one Elasticsearch node. For more advanced setups, you may find information in the following WiFiMon guide "RADIUS Logs Streaming to Elasticsearch - Simulation".

Kibana Configuration

After the installation some configurations are required. Open the Kibana configuration file (/etc/kibana/kibana.yml) and make the following changes in the corresponding sections/fields of the configuration file. Note that, bold parts must be adjusted to your particular configuration.

server.port: 5601
server.host: “INSERT the Fully Qualified Domain Name (WAS_FQDN) to which the server listens”
server.name: “wifimon-kibana”
elasticsearch.hosts: [“http://WAS_FQDN:9200”]
server.ssl.enabled: false

You may start Kibana with: service kibana restart

Verify that kibana is running via: netstat -tlnpu (port 5601)

5. WiFiMon Installation

To install WiFiMon, use the following commands:

wget https://fl-5-205.unil.cloud.switch.ch/wifimon-agent-0.1.1-SNAPSHOT.deb --no-check-certificate

sudo apt-get update
sudo apt-get install -y gdebi
sudo gdebi wifimon-agent-0.1.1-SNAPSHOT.deb

Afterwards, you will be able to see the following files in /usr/lib/wifimon/ directory of the installation computer:

• elasticsearch.sh: Script to create Elasticsearch indices

• kibana-import.ndjson: JSON file to be imported in Kibana to create the necessary visualizations and dashboards

• start.sh: Script for starting WiFiMon GUI and Agent

• secure-processor-0.1.1.war: This incorporates both the WiFiMon Secure and Non-Secure Agent.
  

• ui-0.1.1.war: This incorporates the WiFiMon GUI.

• config: Directory with configuration files that need to be filled in

• keystore: Directory where the Java Keystore should be stored in order to run WiFiMon Agent and GUI on HTTPS

• probes: Contains files related to the configuration of WiFiMon Hardware Probes.
  
• subnets: Contains files related to the configuration of the different subnets visualization.

Give permissions to execute the scripts with the following commands:

chmod +x elasticsearch.sh
chmod +x start.sh

Before executing script elasticsearch.sh, you must install “curl”. This can be done using the following commands:

sudo apt-get update
sudo apt-get install -y curl

You should edit the elasticsearch.sh script based on what interface your Elasticsearch cluster listen on. You should provide the FQDN of the WAS or localhost if the WAS listens on localhost. Add the required indices and some initial data in the Elasticsearch cluster by executing the elasticsearch.sh script.

./elasticsearch.sh

Go to Kibana page, select Management and press Index Patterns to configure them. Insert the following to create wifimon index:

• Index pattern: wifimon

• Time Filter field name: timestamp

• Index pattern ID: wifimon_v0.1 (press advanced options to see this field)

and the following to create radiuslogs index (for the correlation RADIUS Logs with measurements):

• Index pattern: radiuslogs

• Time Filter field name: Timestamp

• Index pattern ID: radiuslogs_v0.1 (press advanced options to see this field)

and the following to create probes index (for the metrics collected from the WiFiMon Hardware Probes):

• Index pattern: probes

• Time Filter field name: timestamp
  

• Index pattern ID: probes_v0.1 (press advanced options to see this field)

and the following to create dhcplogs index (for correlation with DHCP logs):

• Index pattern: dhcplogs

• Time Filter field name: timestamp
  

• Index pattern ID: dhcplogs_v0.1 (press advanced options to see this field)

After you create the index pattern go to Saved Objects tab, press Import and import the kibana-import.ndjson to create the necessary visualizations and dashboards.

Go to config directory and fill in the configuration files (secure-processor.properties, ui.properties). You may ignore the processor.properties file. Note that WiFiMon uses HMAC SHA-512 encryption to encrypt sensitive data (End User IP addresses, End User MAC addresses) that are stored in the Elasticsearch cluster and visualized by Kibana. In secure-processor.properties, you have to define the key of this algorithm (type String).

Start the WiFiMon Secure Agent and WiFiMon GUI: ./start.sh

6. Compile WiFiMon Code

Note: This step is only required if you make changes to the WiFiMon Code.

Get the WiFiMon code from the official repository (https://bitbucket.software.geant.org/projects/WFMON/repos/agent/browse). A requirement to compile WiFiMon code is Apache Maven. You can install it via the following commands:

sudo apt-get update
sudo apt-get install -y maven

Enter the WiFiMon code folder: cd agent

Compile the WiFiMon code using the following commands:

mvn clean install
mvn package

Copy the WiFiMon files in the /usr/lib/wifimon directory:

cp /agent/wifimon-assembly/target/wifimon-agent-bin/secure-processor-0.1.1-SNAPSHOT.war /usr/lib/wifimon/secure-processor-0.1.1.war
cp /agent/wifimon-assembly/target/wifimon-agent-bin/ui-0.1.1-SNAPSHOT.war /usr/lib/wifimon/ui-0.1.1.war

7. Configuring New Subnets for the Subnets Tab

Apart from entering a new subnet in the configuration tab, you are required to create a new entry in the Subnets Tab to monitor your WiFi network. This requires performing a few modifications to the WiFiMon Java code as well as modifying HTML code. In the following, we will demonstrate an example of creating an entry for the subnet a.b.c.d/xx where xx is the subnet netmask. The folder that contains the WiFiMon code is called “agent”. Note that the WiFiMon code includes an entry for the subnet “147.102.13.0/24” for demonstration purposes. You may remove this Subnet or overwrite it with yours.

Edit file /agent/wifimon-ui/src/main/resources/templates/fragments/header.htm

Insert the red lines as below:

<li th:class="${classActiveSettingsSubnets}" class="dropdown"><a class="dropdown-toggle" data-toggle="dropdown" href="#">Subnets<span class="caret"></span></a>

<ul class="dropdown-menu">

<li><a href="#" th:href="@{/secure/Subnets/147_102_13_0_24}">147.102.13.0/24</a></li>

<li><a href="#" th:href="@{/secure/Subnets/a_b_c_d_xx}">a.b.c.d/xx</a></li>

</ul></li>

Copy the template file /usr/lib/wifimon/subnets/elasticsearchSubnets_a_b_c_d_xx.html to /agent/wifimon-ui/src/main/resources/templates/secure/ and substitute a, b, c, d, xx according to the details of the monitored subnet. Inside this file, you should also substitute a, b, c, d, xx according to your setup. In the following, we provide the head of elasticsearchSubnets_147_102_13_0_24 that corresponds to the monitored subnet 147.102.13.0/24:

<head>

<title>Subnets 147.102.13.0/24</title>

<meta name="viewport" content="width=device-width, initial-scale=1"/>

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

<script src="//code.jquery.com/jquery-1.12.0.min.js"></script>

<link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.css"/>

<link href="../../static/css/styling.css" rel="stylesheet" />

<script src="//netdna.bootstrapcdn.com/bootstrap/3.0.0/js/bootstrap.min.js"></script>

</head>

In /usr/lib/wifimon/subnets, you are given a template MeasurementsController_subnets.txt. You have to include this code extract in /agent/wifimon-ui/src/main/java/net/geant/wifimon/agent/controller/MeasurementsController.java and (a) change a, b, c, d and xx according to your setup and (b) enter the link from the Kibana Dashboard where it is requested.

@RequestMapping(value = "/secure/Subnets/a_b_c_d_xx")

public String elasticsearchSubnets_a_b_c_d_xx(Model model, HttpSession session, HttpServletRequest request) {

UrlParameters urlParameters = createUrlParameters(request);

String elasticsearchURL;

elasticsearchURL = environment.getProperty(KIBANA_PROTOCOL) + "://" + environment.getProperty(SERVER_HOST_NAME) + ":" + environment.getProperty(KIBANA_PORT) +

"ENTER_KIBANA_VISUALIZATION_LINK_HERE";

model.addAttribute("classActiveSettingsSubnets", "active");

model.addAttribute("elasticsearchURL", elasticsearchURL);

return "secure/elasticsearchSubnets_a_b_c_d_xx";

}

8. Configuring New Entries in the HW Probes Tab

In the following, we will demonstrate an example of creating an entry for the HW Probe corresponding to the number x, i.e. testtools are NetTest-x, boomerang-x and speedtest-x. The folder that contains the WiFiMon code is called “agent”. Note that the WiFiMon code includes 10 preconfigured WiFiMon HW Probes.

Firstly, you should create a new option in the HWProbes Tab of the WiFiMon GUI for the desired WiFiMon HW Probe with number x. Edit file /agent/wifimon-ui/src/main/resources/templates/fragments/header.html.

Insert the red lines as below:

<li th:class="${classActiveSettingsHWProbes}" class="dropdown"><a class="dropdown-toggle" data-toggle="dropdown" href="#">HWProbes<span class="caret"></span></a>

<ul class="dropdown-menu">

<li><a href="#" th:href="@{/secure/HWProbes/HWProbe1}">HWProbe1</a></li>

<li><a href="#" th:href="@{/secure/HWProbes/HWProbe2}">HWProbe2</a></li>

<li><a href="#" th:href="@{/secure/HWProbes/HWProbe3}">HWProbe3</a></li>

<li><a href="#" th:href="@{/secure/HWProbes/HWProbe4}">HWProbe4</a></li>

<li><a href="#" th:href="@{/secure/HWProbes/HWProbe5}">HWProbe5</a></li>

<li><a href="#" th:href="@{/secure/HWProbes/HWProbe6}">HWProbe6</a></li>

<li><a href="#" th:href="@{/secure/HWProbes/HWProbe7}">HWProbe7</a></li>

<li><a href="#" th:href="@{/secure/HWProbes/HWProbe8}">HWProbe8</a></li>

<li><a href="#" th:href="@{/secure/HWProbes/HWProbe9}">HWProbe9</a></li>

<li><a href="#" th:href="@{/secure/HWProbes/HWProbe10}">HWProbe10</a></li>

<li><a href="#" th:href="@{/secure/HWProbes/HWProbex}">HWProbex</a></li>

</ul>

</li>

Copy the template file /usr/lib/wifimon/probes/elasticsearchHWProbesx.html to /agent/wifimon-ui/src/main/resources/templates/secure/ and substitute x according to your setup. Inside this file, you should also substitute x according to your setup. In the following, we provide the head of elasticsearchHWProbes10 that corresponds to the HW Probe with testtool number 10:

<head>

<title>Metrics for HW Probe 10</title>

<meta name="viewport" content="width=device-width, initial-scale=1"/>

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

<script src="//code.jquery.com/jquery-1.12.0.min.js"></script>

<link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.css"/>

<link href="../../static/css/styling.css" rel="stylesheet" />

<script src="//netdna.bootstrapcdn.com/bootstrap/3.0.0/js/bootstrap.min.js"></script>

</head>

In /usr/lib/wifimon/probes, you are given a template MeasurementsController_probes.txt. You have to include this code extract in /agent/wifimon-ui/src/main/java/net/geant/wifimon/agent/controller/MeasurementsController.java and (a) change x according to your setup and (b) enter the link from the Kibana Dashboard where it is requested.

@RequestMapping(value = "/secure/HWProbes/HWProbex")

public String elasticsearchHWProbe1(Model model, HttpSession session, HttpServletRequest request) {

UrlParameters urlParameters = createUrlParameters(request);

String elasticsearchURL;

elasticsearchURL = environment.getProperty(KIBANA_PROTOCOL) + "://" + environment.getProperty(SERVER_HOST_NAME) + ":" + environment.getProperty(KIBANA_PORT) +

"INSERT_KIBANA_DASHBOARD_LINK_HERE";

model.addAttribute("classActiveSettingsHWProbes", "active");

model.addAttribute("elasticsearchURL", elasticsearchURL);

return "secure/elasticsearchHWProbesx";

}

9. Creating a New Dashboard for a Subnet

In the Kibana user interface, choose the Dashboard section. There, you will find a Dashboard called “SubnetsTimeseries_a.b.c.d/xx”. Add the appropriate filter corresponding to the number of your monitored subnet. For example, if the subnet is a.b.c.d/xx, you should add the following filter “requesterSubnet is a.b.c.d/xx”. Save your dashboard as a new dashboard. Remember to store time with your dashboard.

In Share --> Permanent Links --> Snapshot you can find the URL to include in the WiFiMon Java code.

10. Creating a New Dashboard for a HW Probe

In the Kibana user interface, choose the Dashboard section. There, you will find a Dashboard called “HW Probe Dashboard x”. Add the appropriate filter corresponding to the number of your monitored WiFiMon HW Probe. For example, if the testtool number of your WiFiMon HW Probe is 11, you should add the following filter “testTool is one of NetTest-11 boomerang-11 speedtest-11”. Save your dashboard as a new dashboard. Remember to store time with your dashboard.

In Share --> Permanent Links --> Snapshot you can find the URL to include in the WiFiMon Java code.

11. Configuring WiFiMon Secure Agent

We will demonstrate the configuration of the WiFiMon Secure Agent with a Let’s encrypt certificate. WiFiMon Administrators are free to use whatever certificates they prefer. In the following, we assume that both WiFiMon Analysis Station and WiFiMon Test Server are installed in the same server and thus, use the same certificate. WiFiMon Administrators may install them in separate servers.

First, you have to install certbot:

sudo apt-get update
sudo apt-get install -y certbot

Request a certificate for the FQDN of your server:

certbot certonly --webroot -w /var/www/html -d WAS_FQDN

Note: Before this step, you need to allow connections to your Apache Web Server.

Issued certificates can be renewed with: certbot renew

1. Overview of the WiFiMon Analysis Station (WAS) Installation

A summary of the mandatory steps for the installation (detailed in the linked sections below):

• Installation of PostgreSQL

• Creation of database, users and tables in PostgreSQL

• Installation of Java

• Installation of Elasticsearch

• Installation of Kibana

• Configuration of Elasticsearch

• Configuration of Kibana

• Installation of WiFiMon Agent and WiFiMon GUI

• Run the services

• Links to the WiFiMon GUI

There are also some optional steps:

• Compilation of the WiFiMon code

• Configuration of the WiFiMon Secure Agent certificate

• Configuration of X-Pack

Anchor
PostgreSQL PostgreSQL

2. PostgreSQL

Installing PostgreSQL from a package manager requires using the following commands:

sudo apt-get install -y postgresql postgresql-contrib

By default, PostgreSQL is configured to listen on localhost. We suggest that this default configuration is not modified.

After the installation of PostgreSQL, the database and tables required by WiFiMon should be created.  Detailed instructions are included in the following subsections.

Anchor
database database

2.1. Database and User Creation

The following code block includes the appropriate SQL commands required to create (i) a database that will store information related to Subnets and Access Points monitored by WiFiMon as well as accounts of users that can access the WiFiMon GUI and (ii) a user that will be able to access this database. The following commands create the (i) database "wifimon_database" and (ii) the user "wifimon_user" with password "wifimonpass". We strongly suggest that these example names are changed in production environments.

Accessing PostgreSQL requires becoming user "postgres". This is possible from the "root" user using the command “su postgres”. Afterwards, the terminal-based front-end of PostgreSQL is accessed using the command "psql". 

CREATE USER wifimon_user WITH PASSWORD 'wifimonpass';
CREATE DATABASE wifimon_database OWNER wifimon_user;

After the creation of the database "wifimon_database", selecting this database is possible via the following command:

\c wifimon_database;

The following subsections include the commands that are necessary for the creation of the required tables.

2.2. Creation of "subnets" Table

WiFiMon measures the performance of WiFi networks by embedding JavaScript code in frequently visited websites. Performance tests are triggered when End Users visit these websites and, in particular, after a web page is loaded so that browsing experience is not impacted by WiFiMon. Notably, these websites are not only visited by End Users residing in the monitored Subnets, but also from End Users outside them. Thus, alleviating the WAS from processing excessive traffic requires that performance tests consider measurements originating only from the WiFi networks that are monitored. To that end, a list of the registered Subnets from which End User measurements are processed by the WAS are maintained in "subnets" table. The creation of this table is detailed in the following code block.

CREATE TABLE subnets (
subnet text,
subnet_id serial PRIMARY KEY );

2.3. Creation of "accesspoints" Table

Table "accesspoints" is used to store information related to the Access Points monitored by WiFiMon. This information includes the latitude and longitude of Access Points, the building and floor in which they are installed and additional notes about them. This information is later used to depict performance results of End User measurements per Access Point. The creation of the "accespoints" table is detailed in the following code block.

CREATE TABLE accesspoints (
apid serial PRIMARY KEY,
mac text NOT NULL,
latitude text,
longitude text,
building text,
floor text,
notes text);

2.4. Creation of "users" Table

Table "users" is used to store information related to WiFiMon Users. WiFiMon GUI can be accessed by two types of WiFiMon Users: ADMIN and USER. ADMIN has full privileges to the WiFiMon GUI. An ADMIN is capable of adding/removing registered Subnets and Access Points as well as adding/removing WiFiMon Users. In contrast, a USER can navigate through the WiFiMon GUI dashboards, but is incapable of performing administration actions. The creation of the "users" table is detailed in the following code block.

CREATE TABLE users (
id serial PRIMARY KEY,
email text NOT NULL,
password_hash text NOT NULL,
role text NOT NULL);

2.5. Creation of "options" Table

Table "options" stores information related to privacy settings, e.g. hiding/showing End User specific data in the WiFiMon GUI. Correlation options are also included in this table. The creation of the "options" table is detailed in the following code block.

CREATE TABLE options (
optionsid serial PRIMARY KEY,
userdata text NOT NULL,
uservisualoption text NOT NULL,
correlationmethod text NOT NULL
);

Exiting the database is possible using the command "\q" within the terminal-based front-end of PostgreSQL.

Setting Privileges in PostgreSQL

Setting SELECT, INSERT, DELETE, UPDATE privileges for the database user, e.g. "wifimon_user" requires the following commands issued within the terminal-based front-end of PostgreSQL:

GRANT USAGE ON SCHEMA public to wifimon_user;
GRANT CONNECT ON DATABASE wifimon_database to wifimon_user;

\c wifimon_database

GRANT USAGE ON SCHEMA public to wifimon_user;
GRANT SELECT ON subnets, users, accesspoints, options TO wifimon_user;
GRANT INSERT ON subnets, users, accesspoints, options TO wifimon_user;
GRANT DELETE ON subnets, users, accesspoints, options TO wifimon_user;
GRANT UPDATE ON accesspoints, options TO wifimon_user;
GRANT USAGE, SELECT ON SEQUENCE subnets_subnet_id_seq TO wifimon_user;

GRANT USAGE, SELECT, UPDATE ON SEQUENCE options_optionsid_seq TO wifimon_user;
GRANT USAGE, SELECT, UPDATE ON SEQUENCE accesspoints_apid_seq TO wifimon_user;

Exiting the database is possible using the command "\q" within the terminal-based front-end of PostgreSQL.

Create an admin account to login

An initial ADMIN WiFiMon User should be created for accessing the WiFiMon GUI. Within the terminal-based front-end of PostgreSQL, an ADMIN WiFiMon User is created using the commands in the following code block after connection to the WiFiMon database. Notably, passwords are stored hashed within the database.

\c wifimon_database

INSERT INTO users VALUES ('1', 'admin@test.com', '$2a$06$AnM.QevGa4BPGg7hc3nEBua6stnbZ8h4PrCjSbDxW.LWL7t4MX8vO', 'ADMIN');

Inserting this entry to the "users" table creates an ADMIN WiFiMon User that is able to login in the WiFiMon GUI using the following credentials:

Email: admin@test.com

Password: admin1

This account can be later deleted from the WiFiMon GUI (after step 5). However, an ADMIN account should always be present in order to access the WiFiMon GUI and manage the WiFiMon Users, Access Points and Subnets. We strongly suggest that the password is changed from the WiFiMon GUI when the installation is complete (step 5).

3. Java Installation

WiFiMon currently supports Java 11. The required commands are the following:

sudo apt update
sudo apt-get install -y openjdk-11-jdk openjdk-11-jre

Java installation can be verified with the following command:

java -version

Setting the JAVA_HOME variable requires (i) finding the installed Java alternatives using the following command "sudo update-alternatives --config java" and (ii) modifying the /etc/environment configuration file based on the output of the previous command. In our case, JAVA_HOME requires the following value:

JAVA_HOME="/usr/lib/jvm/java-11-openjdk-amd64"

Changes are applied with the following command:

source /etc/environment

4. Elasticsearch and Kibana

Installing Elasticsearch 7.9.3 and Kibana 7.9.3, requires executing the following commands:

• Elasticsearch 7.9.3

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.9.3-amd64.deb
sudo dpkg -i elasticsearch-7.9.3-amd64.deb

• Kibana 7.9.3

elasticsearch_configure elasticsearch_configure

Elasticsearch Configuration

In the configuration file of Elasticsearch (/etc/elasticsearch/elasticsearch.yml), the following lines should be inserted/changed. Notably, bold parts must be adjusted to the particular configuration of the reader. In the following, we configure Elasticsearch to be publicly accessible:

The Elasticsearch cluster should be started with the following command:

service elasticsearch restart

Verifying that Elasticsearch is running is possible via: netstat -tlnpu (ports 9200, 9300)

Notably, "cluster.initial_master_nodes" must be commented out after the first initialization of the Elasticsearch cluster. The above configuration assumes that the setup includes a single Elasticsearch node. Configuration for more advanced setups is available in the following WiFiMon guide "Streaming Logs Into ELK Cluster".

Anchor
kibana_configure kibana_configure

Kibana Configuration

After installing Kibana, the following configurations are required in the Kibana configuration file (/etc/kibana/kibana.yml). The following changes should be made in the corresponding sections/fields of the configuration file. Notably, bold parts must be adjusted to the particular configuration of the reader.

Kibana should be started with the following command:

service kibana restart

Verifying that kibana is running is possible via: netstat -tlnpu (port 5601)

5. WiFiMon Installation

Installing WiFiMonrequires the following commands:

wget http://83.97.95.167/deb/wifimon-agent-1.3.0.deb
sudo apt-get update
sudo apt-get install -y gdebi
sudo gdebi wifimon-agent-1.3.0.deb

Afterwards, the following files will show up in /usr/lib/wifimon/ directory:

• elasticsearch.sh: Script to create Elasticsearch indices

• kibana-import.ndjson: JSON file to be imported in Kibana to create the necessary visualizations and dashboards

• start.sh: Script for starting WiFiMon GUI and Agent

• secure-processor-1.3.0war: This incorporates both the WiFiMon Secure and Non-Secure Agent
  

• ui-1.3.0.war: This incorporates the WiFiMon GUI

• config: Directory with configuration files. Their parameters must be filled in.

• keystore: Directory where the Java Keystore should be stored in order to run WiFiMon Agent and GUI on HTTPS

chmod +x elasticsearch.sh
chmod +x start.sh

Before the execution of script elasticsearch.sh, "curl" must be installed. This is possible using the following commands:

sudo apt-get update
sudo apt-get install -y curl

Script elasticsearch.sh must be edited to match the interface the Elasticsearch cluster listens to. To that end, the variable FQDN with the elasticsearch.sh file should be substituted with the value of the "network.host" attribute in "/etc/elasticsearch/elasticsearch.yml" file. Script elasticsearch.sh will add the required indices and some initial data in the Elasticsearch cluster:

./elasticsearch.sh

In the sequel, Kibana index patterns should be configured from the Kibana User Interface. In Kibana, the "wifimon" index pattern can be created from Management/Stack Management/Index Patterns. The following details should be provided:

• Index pattern: wifimon

• Time Filter field name: timestamp

• Index pattern ID: wifimon_v0.1 (advanced options should be selected to see this field)

and the following details are required to create "probes" index (for the metrics collected from the WiFiMon Hardware Probes):

• Index pattern: probes

• Time Filter field name: timestamp
  

• Index pattern ID: probes_v0.1 (advanced options should be selected to see this field)

After the creation of index patterns, the necessary visualizations and dashboards should be imported. To that end, the kibana-import.ndjson file should be imported in the Management/Stack Management/Saved Objects tab.

Finally, WiFiMon properties should be configured in the files (secure-processor.properties, ui.properties) of the WiFiMon config directory. Notably, WiFiMon uses HMAC SHA-512 encryption to encrypt sensitive data (End User IP addresses, End User MAC addresses) that are stored in the Elasticsearch cluster and visualized by Kibana. In secure-processor.properties, the key of this algorithm must be defined (property "sha.key"). This key is of type String and the reader could select any well-formatted string, preferably of big length. This string is defined only in the secure-processor.properties configuration file.

Apart from the "sha.key" property, the WiFiMon administrator is required to provide the port on which the WAS listens (property "server.port"), i.e. 9000 for the case of the WiFiMon Non-Secure Agent. Later, this documentation demonstrates how to install the WiFiMon Secure Agent; the WiFiMon Administrator is then required to change the value of the "server.port" property to 8443 from 9000.

Moreover, the WiFiMon Administrator should set the value of the PostgreSQL properties according to what was provided in the 2nd step of this documentation. Based on the example values of our documentation, "spring.datasource.url" can be defined as "jdbc:postgresql://localhost:5432/wifimon_database" and "spring.datasource.username", "spring.datasource.password" properties can be defined as "wifimon_user", "wifimonpass" respectively. Please, make sure that you change the aforementioned password to secure your PostgreSQL database setup.

Afterwards, the WiFiMon Administrator is required to provide the name of the Elasticsearch cluster ("elasticsearch.clustername" property) that was provided in step 4 of this documentation (e.g. "elasticsearch" in this guide) and the FQDN Elasticsearch listens on for the "elasticsearch.host" property.

In ui.properties, the WiFiMon Administrator is expected to provide the values for the PostgreSQL properties (the same as in the secure-processor.properties file) as well as the Kibana properties. Specifically, the WiFiMon Administrator should insert the FQDN Kibana listens on ("server.host.name" property), the protocol used by Kibana ("kibana.protocol" property), which is "http" for the WiFiMon Non-Secure Agent (this step) or "https" for the WiFiMon Secure Agent (step 7 of this documentation) as well as the port Kibana listens to ("kibana.port" property), which is usually 5601. Finally, WiFiMon provides methods for checking if a new software version is available. To that end, the running version of the WiFiMon software is compared with the most recent version that is stored within a VM provided by GEANT. Moreover, this VM keeps some statistics of WiFiMon end users involving their IP address and running version. The purpose of this is to track how many users are currently utilizing WiFiMon and what versions. If the WiFiMon end user wants to be excluded from this process, "user.tracking" should be changed to "no".

Starting the WiFiMon Secure Agent and WiFiMon GUI requires the following command:

./start.sh

6. WiFiMon Code Compilation

Note: This step is only required if the WiFiMon Code is modified by the reader to include new features.

The WiFiMon code can be obtained from the official repository (https://bitbucket.software.geant.org/projects/WFMON/repos/agent/browse). A requirement to compile WiFiMon code is Apache Maven. It can be installed via the following commands:

sudo apt-get update
sudo apt-get install -y maven

Within the WiFiMon code folder (cd agent), the WiFiMon code ban be compiled using the following commands:

mvn clean install
mvn package

Afterwards, WiFiMon war files should be copied in the /usr/lib/wifimon directory:

cp agent/wifimon-assembly/target/wifimon-agent-bin/secure-processor-1.3.0.war /usr/lib/wifimon/secure-processor-1.3.0.war
cp agent/wifimon-assembly/target/wifimon-agent-bin/ui-1.3.0.war /usr/lib/wifimon/ui-1.3.0.war

letsencrypt letsencrypt

7. Configuration of the WiFiMon Secure Agent

Configuration of the WiFiMon Secure Agent will be demonstrated using a Let’s encrypt certificate. Readers are free to use whatever certificate they prefer.

In the sequel, we assume that both the WAS and the WiFiMon Test Server (WTS) are installed within the same machine and thus, they depend on the same certificate. Notably, the WAS and the WTS could be installed in separate machines. Moreover, the configuration is demonstrated for an Apache web server. However, any web server could be selected. 

Firstly, installation of certbot is required:

sudo apt-get update
sudo apt-get install -y certbot

A certificate must be requested for the FQDN of the WAS/WTS, referred as WAS_FQDN:

certbot certonly --webroot -w /var/www/html -d WAS_FQDN

Note: Prior to this step, connections to port 80 must be allowed. If a web server is already installed on the machine, it should be temporarily stopped.

Issued certificates should be renewed regularly using the following command:

certbot renew

Next, generated certificates/keys will be inserted in the Apache configuration files. File Next, we will insert generated certificates/keys in the Apache configuration files. Edit file /etc/apache2/sites-available/default-ssl.confconf should be edited and change the following lines :should be changed based on the FQDN of the WAS/WTS, referred as WAS_FQDN.

Apply changes and enable SSL:

...

Changes should be applied and SSL should be enabled using the following commands:

a2ensite default-ssl

...

a2enmod ssl

...

systemctl restart apache2

You may find more information More information is available in the following links from which the above commands are taken:

https://www.server-world.info/en/note?os=Ubuntu_18.04&p=ssl&f=2

https://www.server-world.info/en/note?os=Ubuntu_18.04&p=httpd&f=8

Copy these files The following files should be copied in /usr/lib/wifimon/keystore:

cp /etc/letsencrypt/live/WAS_FQDN/cert.pem /usr/lib/wifimon/keystore/cert.pem

...

cp /etc/letsencrypt/live/WAS_FQDN/privkey.pem /usr/lib/wifimon/keystore/privkey.pem

...

cp /etc/letsencrypt/live/WAS_FQDN/chain.pem /usr/lib/wifimon/keystore/chain.pem

Navigate to Within /usr/lib/wifimon/keystore folder. PEM , PEM certificates should be converted to Java Keystore (JKS) format using the following commands:openssl pkcs12

openssl pkcs12 -export -in cert.pem -inkey privkey.pem -certfile cert.pem -out testkeystore.p12

...

keytool -importkeystore -srckeystore testkeystore.p12 -srcstoretype pkcs12 -destkeystore wifimon.jks -deststoretype JKS

Enter and note passwords Passwords should be provided when prompted and noted.

In /usr/lib/wifimon/config/secure-processor.properties, make the following changes should be made:

In /usr/lib/wifimon/config/ui.properties, make the following changes should be made:

Furthermore, change the following parameters of the file /etc/kibana/kibana.yml should be changed:

Moreover, in your WiFiMon Test Server, change the agentPort the WTS test pages, the agentPort should be agent from 9000 to 8443 in every testtool HTML page as well as http to https. Moreover, do not forget to change http  http should be changed to https in /var/www/html/wifimon/js/nettest/nettest-swfobject.js. This is a file related to the NetTest testtool. More information about these parameters is included in the WiFiMon Test Server (WTS) installation guide.

WiFiMon is now configured to use HTTPS for WiFiMon GUI and Agent.

8. Configuring ELK Stack Security (X-Pack)

We In the sequel, we will secure the ELK stack using a self-signed certificate. First, you have to create the file “/usr/share/elasticsearch/instances.yml” yml” should be created with the following contents:

instances:

...

      - name: elasticsearch

...

        dns: WAS_FQDN

...

        ip: WAS_IP

Important Note: In case you also configure Logstash, instancesof correlation with RADIUS and DHCP Logs, Logstash is also required. In this case, instances.yml requires additional information. Please, see More information is available in the following WiFiMon guide "RADIUS Logs Streaming to Elasticsearch - Simulation". You should combine the information provided in these two guides to fully configure the WiFiMon Analysis ServerStreaming Logs Into ELK Cluster". The WAS guide mainly focuses on the integration of the previous guide with the WiFiMon code setup.

Then, you will generate the certificate of the Certificate Authority (CA) and its corresponding key . Use should be generated using the following command:

/usr/share/elasticsearch/bin/elasticsearch-certutil ca --ca-dn CN=’WiFiMon CA’ --days 3650 --keysize 4096 --out wifimon-ca.zip --pass --pem

This command will create the file “wifimon“wifimon-ca.zip” zip” in /usr/share/elasticsearch directory. Unzip this file The file contents should be unzipped using the following command:

unzip /usr/share/elasticsearch/wifimon-ca.zip

Then, you will generate , the self-signed certificate and the corresponding key . Use should be generated using the following command:

/usr/share/elasticsearch/bin/elasticsearch-certutil cert --ca-cert /usr/share/elasticsearch/ca/ca.crt --ca-key /usr/share/elasticsearch/ca/ca.key --days 1234 --in /usr/share/elasticsearch/instances.yml --keysize 4096 --out wifimon-certs.zip --pass --pem

This command will create wifimon-certs.zip file in /usr/share/elasticsearch directory. Unzip The contents of this file should be unzipped using the following command:

unzip /usr/share/elasticsearch/wifimon-certs.zip

Create directories Directories /etc/elasticsearch/certs and /etc/kibana/certs. Copy files certs should then be created. Files ca.crt, elasticsearch.key and elasticsearch.crtcrt should be copied in the aforementioned directories and in /usr/lib/wifimon/keystore.keystore using the following commands:

mkdir /etc/elasticsearch/certs

...

mkdir /etc/kibana/certs

...

cp /usr/share/elasticsearch/ca/* /etc/elasticsearch/certs/

...

cp /usr/share/elasticsearch/ca/* /etc/kibana/certs/

...

cp /usr/share/elasticsearch/elasticsearch/* /etc/elasticsearch/certs/

...

...

cp /usr/share/elasticsearch/ca/* /usr/lib/wifimon/keystore/

...

cp /usr/share/elasticsearch/elasticsearch/* /usr/lib/wifimon/keystore/

Then, you will configure the elasticsearch keystore . Use should be configured using the following command:

/usr/share/elasticsearch/bin/elasticsearch-keystore create

Add Adding certificate key passphrase for HTTP communication protocol . Use requires using the following command and enter entering the elasticsearch certificate key passphrase when prompted:

/usr/share/elasticsearch/bin/elasticsearch-keystore add xpack.security.http.ssl.secure_key_passphrase

Add Adding certificate key for transport communication protocol and enter entering the elasticsearch certificate key passphrase when prompted is possible via the following command:

/usr/share/elasticsearch/bin/elasticsearch-keystore add xpack.security.transport.ssl.secure_key_passphrase

  • Upload Timeseries for current day, automatically updated every 30 seconds

  • Ping Timeseries for current day, automatically updated every 30 seconds

• Subnets: This tab includes measurments from each monitored subnet separately.

• Subnets: This tab includes performance measurements for WiFiMon End Users (not WiFiMon Hardware Probes) in the monitored Subnets. By default, the measurements of all WiFiMon End Users are depicted regardless of the Subnet they reside. Visualizing measurements for a specific Subnet requires adding a Kibana filter (along with the existing one) from the "Add filter" option on top. For the example subnet a.b.c.d/xx, the Kibana filter is "requesterSubnet is a.b.c.d/xx".

• HWProbes: This tab includes measurements from the monitored WiFiMon Hardware Probes (not WiFiMon End Users) in the monitored Subnets. By default, the measurements of all WiFiMon Hardware Probes are depicted. Visualizing measurements for a specific WiFiMon Hardware Probe requires adding a Kibana filter (along with the existing one) from the "Add filter" option on top. Each WiFiMon Hardware Probe is assigned a number. For the measurements of the WiFiMon Hardware Probe assigned the number "1", the required Kibana filter is "probeNo is 1". Assigning a number in each WiFiMon Hardware Probe is possible via the "testtool" attribute of the WiFiMon monitored test pages. More information is available in the WiFiMon Test Server installation guideHWProbes: This tab includes measurements from each monitored WiFiMon Hardware Probe separately.

• Statistics:

  • Pie Statistics for current day, automatically updated every 30 seconds (Error: Reference source not found)

  • Table Statistics for current day, automatically updated every 30 seconds
