WiFiMon Analysis Station Installation and Configuration Guide

WiFiMon Analysis Station (WAS) receives:

• 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 Logs from RADIUS Servers.
• Wireless network performance metrics streamed from WiFiMon Hardware Probes.

Note that:

• The above 4 types of information are independent of one another and WiFiMon Administrators may opt for not implementing one or more of them.
• The WiFiMon Analysis Station may be located inside or outside of the monitored WiFi networks.

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 Logs if this information is available.
• Analyzes deterministic measurements received from WiFiMon Hardware Probes and correlates them with information received from RADIUS Logs if this information is available.
• Analyzes wireless network performance metrics received from WiFiMon Hardware Probes.
• Stores results of analysis and correlation.

The WiFiMon GUI is a software component closely associated with the WiFiMon Agent that allows the Administrators to inspect their monitored WiFi networks.

In the rest of the guide, we refer to the WiFiMon Agent as Non-Secure WiFiMon Agent if crowdsourced and deterministic measurements are streamed over HTTP or Secure WiFiMon Agent if measurements are streamed over HTTPS.

The guide presents the commands needed to install the WiFiMon Analysis Station (WAS) in a Debian-based distribution (Debian, Ubuntu, etc.). Other distributions can also be used, by adjusting the apt install commands appropriately.

0. Prerequisites to Install the WiFiMon Analysis Station (WAS)

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

• WiFiMon Agent package
• PostgreSQL (required, tested on version 10.12)
• Java 8
• Elasticsearch (required, tested on version 7.4.2)
• Kibana (required, tested on version 7.4.2)
• Logstash (required in case of correlation with RADIUS and DHCP Logs, tested on version 7.4.2)

The following ports must be available on the WAS. However, the ports may be changed manually depending on your needs:

• 5044: for Logstash

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

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

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

• Install PostgreSQL

• Create database, users and tables in PostgreSQL

• Install Java

• Install Elasticsearch

• Install Kibana

• Configure Elasticsearch

• Configure Kibana

• Install WiFiMon Agent and WiFiMon GUI

• Run the services

• Visit the links to see the WiFiMon GUI

There are also some optional steps:

• Compile the code

• Configure WiFiMon certificate

• Configure X-Pack

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.

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 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;

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 8. Installing Java 8 is detailed in the sequel for the Debian 10 Operating System. These instructions are taken from HERE.

Installing the OpenJDK 8 in Debian 10 requires using the AdoptOpenJDK repository. The required commands are the following:

sudo apt update
sudo apt install -y 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 -y adoptopenjdk-8-hotspot

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. For the adoptojdk-8-hotspot, JAVA_HOME requires the following value:

JAVA_HOME="/usr/lib/jvm/adoptopenjdk-8-hotspot-amd64"

Changes are applied with the following command: source /etc/environment

4. Elasticsearch and Kibana

Installing Elasticsearch 7.4.2 and Kibana 7.4.2, requires executing 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), 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 "RADIUS Logs Streaming to Elasticsearch - Simulation".

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 WiFiMon requires 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, 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-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. 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

Execution permissions are required for scripts elasticsearch.sh and start.sh. These are provided with the following commands:

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 listen to. The FQDN of the WAS should be provided or localhost if the WAS is configured to listen on localhost. 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/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 "radiuslogs" index (for the correlation of RADIUS Logs with End User measurements):

• Index pattern: radiuslogs

• Time Filter field name: Timestamp

• Index pattern ID: radiuslogs_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)

and the following to create "dhcplogs" index (for the correlation of DHCP Logs with End User measurements):

• Index pattern: dhcplogs

• Time Filter field name: timestamp
  

• Index pattern ID: dhcplogs_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/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. 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.

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-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. Configuration of the 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

Next, we will insert generated certificates/keys in the Apache configuration files. Edit file /etc/apache2/sites-available/default-ssl.conf and change the following lines:

Apply changes and enable SSL:

a2ensite default-ssl
a2enmod ssl
systemctl restart apache2

You may find more information in the following links:

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 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 /usr/lib/wifimon/keystore folder. PEM certificates should be converted to Java Keystore (JKS) format:

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 when prompted.

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

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

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

Moreover, in your WiFiMon Test Server, change the agentPort from 9000 to 8443 in every testtool HTML page as well as http to https. Moreover, do not forget to change http to https in /var/www/html/wifimon/js/nettest/nettest-swfobject.js.

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

8. Configuring ELK Stack Security (X-Pack)

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

instances:
      - name: elasticsearch
        dns: WAS_FQDN
        ip: WAS_IP

Note: In case you also configure Logstash, instances.yml requires additional information. Please, see 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 Server.

Then, you will generate the certificate of the Certificate Authority (CA) and its corresponding key. Use 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-ca.zip” in /usr/share/elasticsearch directory. Unzip this file using the following command:

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

Then, you will generate the self-signed certificate and the corresponding key. Use 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 this file using the following command:

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

Create directories /etc/elasticsearch/certs and /etc/kibana/certs. Copy files ca.crt, elasticsearch.key and elasticsearch.crt in the aforementioned directories and in /usr/lib/wifimon/keystore.

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/elasticsearch/* /etc/kibana/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 the following command:

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

Add certificate key passphrase for HTTP communication protocol. Use the following command and enter the certificate key passphrase when prompted:

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

Add certificate key for transport communication protocol and enter the certificate key passphrase:

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

Execute the following command:

/usr/share/elasticsearch/bin/elasticsearch-keystore list

and verify that you have the following:

keystore.seed
xpack.security.http.ssl.secure_key_passphrase
xpack.security.transport.ssl.secure_key_passphrase

In /etc/elasticsearch/elasticsearch.yml add the following and restart the Εlasticsearch cluster:

Generate passwords for the built-in users. Note the passwords as they are not provided again. Inside directory /usr/share/elasticsearch/bin/, use the following command:

./elasticsearch-setup-passwords auto -u "https://WAS_FQDN:9200"

Configure Kibana keystore using the following command:

sudo -u kibana /usr/share/kibana/bin/kibana-keystore create

Use the following command and provide “kibana” as the username:

sudo -u kibana /usr/share/kibana/bin/kibana-keystore add elasticsearch.username

Use the following command and provide the password of the “kibana” built-in user:

sudo -u kibana /usr/share/kibana/bin/kibana-keystore add elasticsearch.password

Use the following command and provide the elasticsearch.key passphrase:

sudo -u kibana /usr/share/kibana/bin/kibana-keystore add server.ssl.keyPassphrase

Execute the following command:

sudo -u kibana /usr/share/kibana/bin/kibana-keystore list

and verify that you have the following:

elasticsearch.username
elasticsearch.password
server.ssl.keyPassphrase

In /etc/kibana/kibana.yml, add the following and restart Kibana:

Make sure that certificates and keys in /etc/elasticsearch/certs/, /etc/kibana/certs/ and /usr/lib/wifimon/keystore/ are accessible by both Εlasticsearch and Kibana.

Next, you will configure the WiFiMon Agent properties. Create the truststore for X-Pack:

keytool -import -trustcacerts -alias root -file /usr/lib/wifimon/keystore/ca.crt -keystore /usr/lib/wifimon/keystore/truststore.jks

Create the keystore for X-Pack:

cat /usr/lib/wifimon/keystore/elasticsearch.crt /usr/lib/wifimon/keystore/elasticsearch.key > /usr/lib/wifimon/keystore/combined.crt

keytool -import -trustcacerts -alias yourdomain -file /usr/lib/wifimon/keystore/combined.crt -keystore /usr/lib/wifimon/keystore/keystore.jks

Edit /usr/lib/wifimon/config/secure-processor.properties and add the following lines:

9. Links to Installed Software
