2.4.3.2. Allin1 - Deployment OpenNAC

2.4.3.2.1. General considerations

Important

This guided install process is designed to be followed step by step.
You need to be alert to the output of each command, because things can fail.
Pay attention to the variable exports, as you need to review this data and configure accordingly to your needs before exporting them.

2.4.3.2.2. Host configuration

The physical host is responsible for running the KVM and ON Sensor. So, our first steps are to configure the host machine.

Export variables

export PUBLIC_IP=10.10.36.200
export PUBLIC_PREFIX=24
export DEFAULT_GW=10.10.36.254
export DNS=10.20.0.11
export ADMIN_IF=eno1
export HOSTNAME=allinC08

Update softwares

sed -i -e "s/=enforcing/=disabled/g" /etc/selinux/config

dnf -y update

dnf -y module install virt

dnf -y install wget virt-install virt-manager virt-viewer libguestfs-tools wget virt-manager xauth tcpdump bridge-utils

systemctl enable libvirtd
systemctl start libvirtd

Configure network interfaces

Attention

In the case of the Intel NUC 8th generation, the eno1 interface will only appear after the dnf update and the reboot.

2.4.3.2.3. Install sensor

Export variables

export ON_VERSION="1.2.3"
export MYSNIFFERINTERFACE=eno1

Install and configure packets

Attention below, as you need to input your Redmine username and, later, your password

wget https://redmine-opennac.opencloudfactory.com/svn_opennac/versions/${ON_VERSION}/src/utils/build-repo/install_sensor.sh --user YOUR_REDMINE_USERNAME --ask-password

Now, to the following steps:

chmod a+x ./install_sensor.sh

./install_sensor.sh --version=${ON_VERSION}

Export variables

export MYSNIFFERINTERFACE=eno1

Install and configure packets

Attention below, as you need to input your Redmine username and, later, your password

wget https://redmine-opennac.opencloudfactory.com/svn_opennac/trunk/src/utils/build-repo/install_sensor.sh --user YOUR_REDMINE_USERNAME --ask-password

Now, to the following steps:

chmod a+x ./install_sensor.sh

./install_sensor.sh

sed -i 's/OPTIONS="-r eth1 -s onmaster -q onmaster"/OPTIONS="-r '${MYSNIFFERINTERFACE}' -q oncore -s onmaster"/' /etc/sysconfig/dhcp-helper-reader

sed -i 's/CAPTURE_INTERFACES=.*$/CAPTURE_INTERFACES="'${MYSNIFFERINTERFACE}'"/' /etc/pf_ring/interfaces.conf

sed -i 's/^interface=.*$/interface='${MYSNIFFERINTERFACE}'/' /opt/bro/etc/node.cfg

Configure the healthcheck:

/usr/bin/cp -rfv /usr/share/opennac/healthcheck/healthcheck.ini.sensor /usr/share/opennac/healthcheck/healthcheck.ini
/usr/bin/cp -rfv /usr/share/opennac/healthcheck/application.ini.sample /usr/share/opennac/healthcheck/application.ini

Install missing packages:

dnf install -y redis
mkdir /var/log/opennac

2.4.3.2.4. Deploy Virtual Machines

The following variable represents the full version that you will have on the OVA files, remember to change it correctly:

Note

Check the last stable version available from OpenNAC Enterprise repository before exporting the variables.

export ONCORE_FULL_VERSION="1.2.3-X.XXX"
export ONANALYTICS_FULL_VERSION="1.2.3-X.XXX"

mkdir -p /home/opennac/core6
mkdir /home/opennac/analytics

wget https://repo-opennac.opencloudfactory.com/ova/opennac_analytics_${ONANALYTICS_FULL_VERSION}_img.ova
wget https://repo-opennac.opencloudfactory.com/ova/opennac_core_${ONCORE_FULL_VERSION}_img.ova

wget https://repo-opennac.opencloudfactory.com/ova/opennac_core_${ONCORE_FULL_VERSION}_img.ova.md5

md5sum -c opennac_analytics_${ONANALYTICS_FULL_VERSION}_img.ova.md5
md5sum -c opennac_core_${ONCORE_FULL_VERSION}_img.ova.md5

If the output from the checksum command is equal to the bad result (seen below), you may have had problems with the download and you should go back to the previous step.

This is a good result:

[root@allin104 ~]# md5sum -c opennac_analytics_1.2.0-4.8471_img.ova.md5
opennac_analytics_1.2.0-4.8471_img.ova: OK

This is a bad result (delete the OVAs, step back and download again):

opennac_analytics_1.2.0-4.8471_img.ova: FAILED
md5sum: WARNING: 1 computed checksum did NOT match

If the checksum is ok, go ahead to the following step:

tar xvf opennac_core_${ONCORE_FULL_VERSION}_img.ova
qemu-img convert -f vmdk -O qcow2 opennac_core_${ONCORE_FULL_VERSION}_img-disk1.vmdk opennac_core_${ONCORE_FULL_VERSION}_img-disk1.qcow2
mv opennac_core_${ONCORE_FULL_VERSION}_img-disk1.qcow2 /home/opennac/core6

tar xvf opennac_analytics_${ONANALYTICS_FULL_VERSION}_img.ova
qemu-img convert -f vmdk -O qcow2 opennac_analytics_${ONANALYTICS_FULL_VERSION}_img-disk1.vmdk opennac_analytics_${ONANALYTICS_FULL_VERSION}_img-disk1.qcow2
mv opennac_analytics_${ONANALYTICS_FULL_VERSION}_img-disk1.qcow2 /home/opennac/analytics

Create and start the machines:

virsh define /home/opennac/core6.xml
virsh define /home/opennac/analytics.xml

virsh create /home/opennac/core6.xml
virsh create /home/opennac/analytics.xml

virsh autostart core6
virsh autostart analytics

virsh start core6
virsh start analytics

Tip

From now on, we need to access the virtual machines. Logout from the console and reconnect to the allinone with a -Y ssh option:

ssh root@<allinoneip> -Y

Now, once we are here, we can open the virt-manager interface, so we can be able to get to the vm console:

virt-manager

Select one of the VMs, click on the “open” button and get the IP information or configure a provisional IP for it. You will find some screenshots for guidance below:

../../../_images/NUC-Allin1-deployment-core-analytics-sensor-01.png

../../../_images/NUC-Allin1-deployment-core-analytics-sensor-02.png

If we don’t have an IP assigned, we need to activate DHCP via

dhclient eth1

After that, we get the IP

../../../_images/NUC-Allin1-deployment-core-analytics-sensor-03.png

The next steps will take place inside each virtual machine console, via SSH.

Configure the healthcheck:

/bin/cp -rfv /usr/share/opennac/healthcheck/healthcheck.ini.master /usr/share/opennac/healthcheck/healthcheck.ini

Log in with the web interface on https://PUBLIC_IP/admin and execute the initial wizard. In the wizard, remember that the Kibana IP should be 192.168.69.10.

Restart the server:

reboot

2.4.3.2.6. Analytics Configuration

Let’s start with the variables exportation

Caution

REMEMBER THAT YOU NEED TO CHANGE THE DATA TO MATCH YOUR REQUIREMENTS (PUBLIC_IP, GW, etc)

export PUBLIC_IP=10.10.36.157

export DEFAULT_GW=10.10.36.254
export DNS=10.20.0.11

Generate and configure the API key

Stop sensor services:

systemctl disable dhcp-helper-reader ; systemctl disable bro ; systemctl disable pf_ring ; systemctl disable filebeat ;

Configure the healthcheck:

/bin/cp -rfv /usr/share/opennac/healthcheck/healthcheck.ini.analy+agg /usr/share/opennac/healthcheck/healthcheck.ini

Reboot the server

reboot

2.4.3.2.7. Host Details (Physical Server)

Now, back in the host server.

Generate and send ssh key.

For the following sco and ssh, you will be prompted for the root password:

ssh-keygen -t rsa

ssh-copy-id -i ~/.ssh/id_rsa.pub root@oncore

ssh-copy-id -i ~/.ssh/id_rsa.pub root@onanalytics

Now that you have already sent the keys, try to connect with them. If the connection does not ask for a password, everything is fine.

ssh root@oncore

ssh root@onanalytics

cat <<EOF > /root/update_allin1.sh
dnf clean all && dnf -y update
ssh root@onanalytics "systemctl stop logstash; systemctl stop kibana; systemctl stop elasticsearch; dnf clean all;dnf -y update logstash kibana elasticsearch; dnf -y update"
ssh root@oncore "/usr/share/opennac/utils/build-repo/update_opennac.sh"
EOF

chmod a+x /root/update_allin1.sh

cd /root/
rm -rf opennac_*
rm -rf install_sensor.sh

2.4.3.2.8. Validations

Access your Core Administration page https://${ip_oncore}/admin;
Access your Core Administration console ssh root@${ip_oncore}
Try to get access to a Network Devices “Switch” ssh admin@${ip_switch}

2.4.3.2.8.1. Use at POC

Below, we have some base steps to execute to use the Allin1 in a PoC:

Connect the USB-ethernet adapter to the indicated USB port.
Connect the external network cable (access and administration) to the USB-ethernet adapter.
Connect the network traffic cable (the one with traffic to be analyzed) to the onboard ethernet port.
Also set up a screen and a keyboard.
Turn on the allin1.
Now, once inside the host, configure change its IP address to one in the customers network. # Restart the network service;
Now you can access it via ssh and then configure the core and analytics.

Note

IMPORTANT: Do not change the IP from the internal network interfaces (the ones 192.168.69.X).

Once you are done changing the IPs, you should be able to access the Core and start using OpenNAC Enterprise (creating policies, showing visibility, etc).
