Magma Overview

Magma Overview
Magma Hands-On

Introduction

Magma is an open-source software platform that gives network operators an open, flexible and extendable mobile core network solution. Magma enables better connectivity by:

Allowing operators to offer cellular service without vendor lock-in with a modern, open source core network
Enabling operators to manage their networks more efficiently with more automation, less downtime, better predictability, and more agility to add new services and applications
Enabling federation between existing MNOs and new infrastructure providers for expanding rural infrastructure
Allowing operators who are constrained with licensed spectrum to add capacity and reach by using Wi-Fi and CBRS

Magma Architecture

The figure below shows the high-level Magma architecture. Magma is designed to be 3GPP generation and access network (cellular or WiFi) agnostic. It can flexibly support a radio access network with minimal development and deployment effort.

Magma has three major components:

Access Gateway: The Access Gateway (AGW) provides network services and policy enforcement. In an LTE network, the AGW implements an evolved packet core (EPC), and a combination of an AAA and a PGW. It works with existing, unmodified commercial radio hardware.
Orchestrator: Orchestrator is a cloud service that provides a simple and consistent way to configure and monitor the wireless network securely. The Orchestrator can be hosted on a public/private cloud. The metrics acquired through the platform allows you to see the analytics and traffic flows of the wireless users through the Magma web UI.
Federation Gateway: The Federation Gateway integrates the MNO core network with Magma by using standard 3GPP interfaces to existing MNO components. It acts as a proxy between the Magma AGW and the operator's network and facilitates core functions, such as authentication, data plans, policy enforcement, and charging to stay uniform between an existing MNO network and the expanded network with Magma.

Access Gateway (AGW)

The main service within AGW is magmad, which orchestrates the lifecycle of all other AGW services. The only service not managed by magmad is the sctpd service (when the AGW is running in stateless mode).

The major services and components hosted within the AGW include

OVS shapes the data plane
control_proxy proxies control-plane traffic
enodebd manages eNodeBs
health checks and reports health metrics to Orchestrator
mme encapsulates MME functionality and parts of SPGW control plane features in LTE EPC
mobilityd manages subscriber mobility
pipelined programs OVS
policydb holds policy information
sessiond coordinates session lifecycle
subscriberdb holds subscriber information

Note: The mme service will be renamed soon to accessd, as its main purpose is to normalize the control signaling with the 4G/5G RAN nodes.

Together, these components help to facilitate and manage data both to and from the user.

Orchestrator (Ocr8r)

Magma's Orchestrator is a centralized controller for a set of networks. Orchestrator handles the control plane for various types of gateways in Magma. Orchestrator functionality is composed of two primary components

A standardized, vendor-agnostic northbound REST API which exposes
configuration and metrics for network devices
A southbound interface which applies device configuration and reports device status

At a lower level, Orchestrator supports the following functionality

Network entity configuration (networks, gateway, subscribers, policies, etc.)
Metrics querying via Prometheus and Grafana
Event and log aggregation via Fluentd and Elasticsearch Kibana
Config streaming for gateways, subscribers, policies, etc.
Device state reporting (metrics and status)
Request relaying between access gateways and federated gateways

Federated Gateway (FEG)

The federated gateway provides remote procedure call (GRPC) based interfaces to standard 3GPP components, such as HSS (S6a, SWx), OCS (Gy), and PCRF (Gx). The exposed RPC interface provides versioning & backward compatibility, security (HTTP2 & TLS) as well as support for multiple programming languages. The Remote Procedures below provide simple, extensible, multi-language interfaces based on GRPC which allow developers to avoid dealing with the complexities of 3GPP protocols. Implementing these RPC interfaces allows networks running on Magma to integrate with traditional 3GPP core components.

The Federated Gateway supports the following features and functionalities:

Hosting centralized control plane interface towards HSS, PCRF, OCS and MSC/VLR on behalf of distributed AGW/EPCs.
Establishing diameter connection with HSS, PCRF and OCS directly as 1:1 or via DRA.
Establishing SCTP/IP connection with MSC/VLR.
Interfacing with AGW over GRPC interface by responding to remote calls from EPC (MME and Sessiond/PCEF) components, converting these remote calls to 3GPP compliant messages and then sending these messages to the appropriate core network components such as HSS, PCRF, OCS and MSC. Similarly the FeG receives 3GPP compliant messages from HSS, PCRF, OCS and MSC and converts these to the appropriate GRPC messages before sending them to the AGW.

Magma NMS provides an enterprise grade GUI for provisioning and operating magma based networks. It enables operators to create and manage:

Organizations
Networks
Gateways and eNodeBs
Subscribers
Policies and APNs

It also aims to simplify operating magma networks by providing

A dashboard of all access gateways and top-level status to determine overall health of infrastructure components at a glance
KPIs and status of a specific access gateway to triage potential infrastructure issues that might need escalation
A dashboard of all subscribers and their top-level status to determine the overall health of internet service at a glance
KPIs and service status of an individual subscriber to triage issues reported by that subscriber
Firing alerts displayed on the dashboard to escalate/remediate the issue appropriately
Fault remediation procedures including the ability to remotely reboot gateways
The ability to peform gateway software upgrades
Ability to remotely troubleshoot through call tracing features.

NMS UI

NMS UI is a React App that uses hooks to manage the internal state. The NMS UI contains various react components to implement NMS page, admin page and the host page. NMS UI primarily uses most of the front end components from Material UI framework.

Host page

Host page contains components for displaying organizations, features, metrics and users in the host portal.

NMS Page

NMS page contains components for displaying dashboard, equipment, networks, policies/APNs, call tracing, subscribers, metrics and alerts. It also contains a network selector button to switch between various networks.

Admin Page

Admin page consists of UI components providing the ability to add networks and users to the respective organizations.

Magmalte

Magmalte is a microservice built using express framework. It contains set of application and router level middlewares.
It uses sequelize ORM to connect to the NMS DB for servicing any routes involving DB interaction.

We will describe the middlewares used in the magmalte app below.

AuthenticationMiddleware

Magmalte uses passport authentication middleware for authenticating incoming requests. Passport authentication within magmalte currently supports

local strategy(where username and password is validated against the information stored in db)
SAML strategy(for enabling enterprise SSO). For enabling this, operator will have to configure the organization entrypoint, issuer name and cert.

SessionMiddleware

Session middleware helps with creating the session, setting the session cookie(use secure cookie in prod deployments) and creating the session object in req. The session token(from environment or hardcoded value) is used to sign the session cookie. The session information is stored in the NMS DB through sequelize. We only serialize userID as part of the session information.

csrfMiddleware

This protects against any CSRF attacks. For more understanding, check this (https://github.com/pillarjs/understanding-csrf#csrf-tokens). Magmalte server includes the csrf tokens when it responds to the client and client submits the form with the token. (nms/app/common/axiosConfig.js)

appMiddleware

Sets some generic app level configuration. Including expecting the body to be json, body not to exceed 1mb and adds compression to the responses.

userMiddleware

Router middlewares to handle login routes for the user

hostOrgMiddleware

Router middleware to ensure that only requests from “host” organization is handled by host routes.

Notes on Routes handling

apiControllerRouter

All Orc8r API calls are handled by apiControllerRouter. ApiControllerRouter acts as a proxy and makes calls to orc8r using th e admin certs present on the container. ApiController Router has networkID filter to ensure that the networkID invoked in the request is part of the organization making the request. On the response side, there is a similar decorator to ensure that networkIDs which belong to the organization is only passed. Additionally, the apicontroller router has a audit log decorator which logs the mutating requests in a auditlogtable in the NMS DB.

networkRouter

Network creation calls are handled by this router and the network is added to the organization and passed on to the apiController.

grafana router

Grafana router is used for displaying the grafana component within iframe in UI. It handles all requests and proxies it to the underlying grafana service. It attempts to synchronize default grafana state when the route is invoked. The default state includes syncing the tenants, user information, datasource and dashboards. The datasource URL is a Orc8r tenants URL(magma/v1/tenants/<org_name>/metrics). NMS certs is also passed along with the datasource information so that grafana can use this to query orc8r and retrieve relevant metrics.
The default state synchronized helps display set of default dashboards to the users. The default dashboards include dashboards for gateways, subscribers, internal metrics etc.
Finally grafana router uses the tenant information synced to ensure that we only retrieve information for networks associated with a particular organization.

NMS DB

After that you have to change docker_socket: /var/run/docker.sock permisson

sudo chmod 666 /var/run/docker.sock

Then back to the ubuntu user to execute the deploy-orc8r.sh to align the IP and user-port
```
sudo bash deploy-orc8r.sh
```
Fill the question with default input, except for the LoadBalancer IP.

Configure the deploy-orc8r.sh to modify my custom script environment

vi deploy-orc8r.sh

Execute this modified script if your're trying to run it for the second time, because of the error on ansible task installing Docker or RKE at the previous step.

deploy-orc8r.sh

#!/usr/bin/env bash

Access Gateway Setup

Step-by-Step AGW Installation

Setting up AGW on Docker Environment

Do pre-installation steps

Copy your rootCA.pem file from orc8r to the following location:
```
mkdir -p /var/opt/magma/certs
vim /var/opt/magma/certs/rootCA.pem
```
Expected Output

Run AGW installation

Download AGW docker install script

wget https://github.com/magma/magma/raw/v1.8/lte/gateway/deploy/agw_install_docker.sh
bash agw_install_docker.sh

Configure AGW

Once you see the output Reboot this machine to apply kernel settings, reboot your AGW host.

Create control_proxy.yml file with your orc8r details:

cat << EOF | sudo tee /var/opt/magma/configs/control_proxy.yml
cloud_address: controller.orc8r.magmacore.link
cloud_port: 443
bootstrap_address: bootstrapper-controller.orc8r.magmacore.link
bootstrap_port: 443
fluentd_address: fluentd.orc8r.magmacore.link
fluentd_port: 24224

rootca_cert: /var/opt/magma/certs/rootCA.pem
EOF

Start your access gateway

cd /var/opt/magma/docker
sudo docker compose --compatibility up -d

Now get Hardware ID and Challenge key and add AGW in your orc8r:

docker exec magmad show_gateway_info.py

Then restart your access gateway:

sudo docker compose --compatibility up -d --force-recreate

Connecting AGW to NMS

ON PROGRESS

Motivation

Previously, to register a gateway, the operator would have to gather the gateway information (both the hardware ID and the challenge key) through show_gateway_info.py script, then provision the gateway with the correct values of control_proxy.yml and rootCA.pem.
Then, the operator would have to register each gateway through the NMS UI and validate the gateway registration by running checkin_cli.py.

In efforts to simplify gateway registration, the new registration process only requires two steps: registering the gateway at Orc8r and then running register.py at the gateway.

Solution Overview 1

The overview of gateway registration is as follows:

gateway_registration_overview

Note: The operator should set per-tenant default control_proxy.yml through the API endpoint \tenants\{tenant_id}\control_proxy as a prerequisite.
The control proxy must have \n characters as line breaks. Here is a sample request body:

{
   "control_proxy": "nghttpx_config_location: /var/tmp/nghttpx.conf\n\nrootca_cert: /var/opt/magma/certs/rootCA.pem\ngateway_cert: /var/opt/magma/certs/gateway.crt\ngateway_key: /var/opt/magma/certs/gateway.key\nlocal_port: 8443\ncloud_address: controller.magma.test\ncloud_port: 7443\n\nbootstrap_address: bootstrapper-controller.magma.test\nbootstrap_port: 7444\nproxy_cloud_connections: True\nallow_http_proxy: True"
}

The operator registers a gateway partially (i.e., without its device field) through Orc8r through an API call. It will receive a registration token, the rootCA.pem, and its Orc8r's domain name in the response body under the field registration info. For example,

{
   "registration_info": {
      "domain_name": "magma.test",
      "registration_token": "reg_h9h2fhfUVuS9jZ8uVbhV3vC5AWX39I",
      "root_ca": "-----BEGIN CERTIFICATE-----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\nWLRlFB4QVm8w\n-----END CERTIFICATE-----\n"
   }
}

The registration token expires every 30 minutes and automatically refreshes every time the operator fetches this unregistered gateway.

The operator runs the register.py script at the gateway with the registration token and its Orc8r's domain name.

MAGMA-VM [/home/vagrant]$ sudo /home/vagrant/build/python/bin/python3 ~/magma/orc8r/gateway/python/scripts/register.py [-h] [--ca-file CA_FILE] [--cloud-port CLOUD_PORT] [--no-control-proxy] DOMAIN_NAME REGISTRATION_TOKEN

The operator can optionally set the root CA file with the --ca-file CA_FILE flag or disable writing to the control proxy file with the --no-control-proxy flag.
sudo permission is necessary because the script needs write access to the file /var/opt/magma/configs/control_proxy.yml for configuring the gateway.
For example, in a testing environment with the rootCA.pem and control_proxy.yml configured, the operator could run

MAGMA-VM [/home/vagrant]$ sudo /home/vagrant/build/python/bin/python3 ~/magma/orc8r/gateway/python/scripts/register.py magma.test reg_t5S4zjhD0tXRTmkYKQoN91FmWnQSK2  --cloud-port 7444 --no-control-proxy

Upon success, the script will print the gateway information that was registered and run checkin_cli.py automatically. Below is an example of the output of a successful register attempt.

Solution Overview 2

The Network Management System (NMS) can be used as UI to manage the AGW connection. This UI is the easy way to perform the connection between elements. Please consider the next:

Assume that the Orchestrator bootstrapper service IP is 192.168.1.248.
Assume that the Orchestrator controller service IP is 192.168.1.248.
Assume that the fluentd service IP is 192.168.1.247.
Assume that the NMS service IP is 10.233.39.105.
Assume that the AGW IP is 192.168.1.88 and the user of VM is magma.
It is assumed that you have already deployed the orchestrator using Helm. Please see sections:
- Deploy Magma Orchestrator using Helm

In this case, consider the next environment variables before continue the procedure:

export MAGMA_ROOT=~/magma_v1.6

Step-by-Step Integration

Check the Certificate Validation

The next sections asumes that you have already deployed an Orchestrator and have the certificates needed for connection to AGW. The next commands can help you to verify these points.

# In the deployment machine:
cd $MAGMA_ROOT/orc8r/cloud/helm/orc8r/charts/secrets/.secrets/certs
ls -1
# admin_operator.key.pem
# admin_operator.pem
# admin_operator.pfx
# bootstrapper.key
# certifier.key
# certifier.pem
# controller.crt
# controller.csr
# controller.key
# rootCA.key
# rootCA.pem
# rootCA.srl
# vpn_ca.crt
# vpn_ca.key

In the next sections, the rootCA.pem certificate is neccesary. For this reason, later in this documentation is explained how to transfer the certificate to AGW VM.

Copy the Certificate

Copy the rootCA.pem certificate from the orchestrator deployment in the AGW machine and put it in the /var/opt/magma/certs/ folder. Use the kubectl command to get the certificate:

kubectl get secret/orc8r-secrets-certs -n magma -o "jsonpath={.data.rootCA\.pem}" | base64 --decode
# -----BEGIN CERTIFICATE-----

# -----END CERTIFICATE-----

Configure the Certificate

In AGW put the rootCA.pem in /var/opt/magma/certs/ folder:

ls -1 /var/opt/magma/certs/
# gateway.crt
# gateway.key
# gw_challenge.key
# rootCA.pem    <--- Certificate for auth to orc8r

NOTE: Also, you can transfer the rootCA.pem cert using sftp or scp:
sudo sftp ubuntu@<secrets_ip>:$MAGMA_ROOT/orc8r/cloud/helm/orc8r/charts/secrets/.secrets/certs/rootCA.pem .

Modify the /etc/hosts in AGW Machine

Next, modify the /etc/hosts file in AGW machine for DNS resolution. Be sure to use the IPs assigned by the cluster for each service of interest. In this case, the services are specified in the beginning table:

sudo vi /etc/hosts
## Add the next lines
# 192.168.1.248 controller.magma.svc.cluster.local
# 192.168.1.248 bootstrapper-controller.magma.svc.cluster.local
# 192.168.1.247 fluentd.magma.svc.cluster.local

Validation Connectivity test

Make sure that you have connectivity to the orchestrator services:

ping -c 4 controller.magma.svc.cluster.local
ping -c 4 bootstrapper-controller.magma.svc.cluster.local
pinc -c 4 fluentd.magma.svc.cluster.local

Edit Proxy Configuration

By default, the control_proxy.yml file have a configuration that use wrong ports to talk with the orchestrator. It is necessary edit the ports as shown below:

sudo vi /etc/magma/control_proxy.yml

control_proxy.yml

Please see how the ports for controller.magma.svc.cluster.local, bootstrapper-controller.magma.svc.cluster.local and fluentd.magma.svc.cluster.local are 8443. 8444 and 24224 respectively.

Generate a new key for the AGW

If you try before to connect the AGW, the orchestrator saves the Hardware UUID and the Challenge Key in a local database that prevents a connection of an AGW with the same combination. For this reason, we suggest to generate a new key and then, perform the connection. In the AGW machine execute the next commands:

sudo snowflake --force-new-key
cd && show_gateway_info.py    # Verify the new key
# Example of output:
# Hardware ID
# -----------
# e828ecb7-64d4-4b7c-b163-11ff3f8abbb7
# 
# Challenge key
# -------------
# MHYwEAYHKoZIzj0CAQYFK4EEACIDYgAERR/0pjjOI/3VVFUJmphurMHhlgxyVHxkJ9QDovgLC99lImKOvUHzKEqlNwsqxmCyWyuyZnNpf8lOaWNmoclbGcXFwh1EeTlIUZmvW1rqj8iPO17AQRgpHJYN5F30eaHa
# 
# Notes
# -----
# - Hardware ID is this gateway's unique identifier
# - Challenge key is this gateway's long-term keypair used for
#   bootstrapping a secure connection to the cloud

Now delete old AGW certificates and restart services

sudo rm /var/opt/magma/certs/gateway*
# Restart magma services
sudo service magma@* stop
sudo service magma@magmad restart
sudo service magma@* status

Verify that you have 200 response in HTTPv2 messages in control_proxy service

Execute this after do NMS Configuration below

 sudo service magma@control_proxy status

NMS Configuration

When you start all AGW services, the AGW is able to connect with the orchestrator. For perform this task, there are two possible ways:

Using the API that orchestrator provides.
Using the NMS interface.

In this case, the second option is considered. First, access to the UI. You should see something like the next image:

NMS First Interface

Once in the NMS, go to the Administrative Tools option:

Administrative Tools

Next, go to the Networks tab and add a new network.

NOTE: You can have multiple AGWs on the same network.

Add Network

With the network created, you can go to the Network Management option and, next, go to the network that you created in the previous step. These steps are shown in the following figures:

Network Management
Network Created

In the emerged interface, go to the Equipment tab and select it. You should see all the AGW that you add to the current network. Also, you can see the health of each AGW, latency and another statistics.

Gateways

In the up-right part of the UI, select the Add New option for add a new AGW:

You should see a new interface where needed some AGW information.

Add New Gateway

Gateway ID: Must be unique. We suggest IDs like agw01, agw02, etc.
Hardware UUID: Go to AGW VM and run show_gateway_info.py. An example of the output is showed below:

# In the AGW machine:
cd && show_gateway_info.py
# Hardware ID:
# ------------
# 9bf9e76c-672a-4b65-a30c-91322f53190a

Version: Leave it empty. The orchestrator must be recognize the version when the AGW Check In Successful.
Gateway Description: Any.

For Aggregation tab leave it by default.

For EPC tab:

Nat Enabled: True.
IP Block: Depends on number of eNBs and users. Leave it by default if there are few.
DNS Primary: We suggest leave empty. In any case, it is configurable after.
DNS Secondary: We suggest leave empty. In any case, it is configurable after.

NOTE: If your AGW is connected to an operator's network, use the DNS primary/secondary that they suggest.

For RAN leave it all by default.

In Equipment tab you should see the AGW with a Good Health. You can see that, in NMS interface, this AGW has a good Health.

End-to-End Setup

ON PROGRESS USING srsRAN

Introduction

srsRAN is a 4G and 5G software radio suite. Usually eNodeB and UE are used with actual RF front-ends for over-the-air transmissions. There are, however, a number of use-cases for which RF front-ends might not be needed or wanted. Those use-cases include (but are not limited to) the use of srsRAN for educational or research purposes, continuous integration and delivery (CI/CD) or development and debugging.

With srsRAN this can be achieved by replacing the radio link between eNodeB and UE with a mechanism that allows to exchange baseband IQ samples over an alternative transport. For this purpose, we’ve implemented a ZeroMQ-based RF driver that essentially acts as a transmit and receive pipe for exchanging IQ samples over TCP or IPC.

ZeroMQ Installation

First thing is to install ZeroMQ and build srsRAN. On Ubuntu, ZeroMQ development libraries can be installed with:

# Install prerequisites
sudo apt-get -y install libzmq3-dev build-essential cmake libfftw3-dev libmbedtls-dev libboost-program-options-dev libconfig++-dev libsctp-dev libtool autoconf automake
# Install libzmq
git clone https://github.com/zeromq/libzmq.git ~/libzmg && cd ~/libzmg
./autogen.sh
./configure
make
sudo make install
sudo ldconfig
# Install czmq
git clone https://github.com/zeromq/czmq.git ~/czmq && cd ~/czmq
./autogen.sh
./configure
make
sudo make install
sudo ldconfig
# Compile srsRAN
git clone https://github.com/srsRAN/srsRAN.git ~/srsRAN && cd ~/srsRAN
mkdir build && cd build
cmake ../
make

Put extra attention in the cmake console output. Make sure you read the following line:

...
-- FINDING ZEROMQ.
-- Checking for module 'ZeroMQ'
--   No package 'ZeroMQ' found
-- Found libZEROMQ: /usr/local/include, /usr/local/lib/libzmq.so
...

Running the RAN

We will run each srsRAN application in a seperate terminal instance. To run any element, it is necessary to be in the compilation folder first and to guarantee that the configuration files are in the /etc/srsran/ folder.

sudo mkdir -p /etc/srsran/
sudo cp ~/srsRAN/srsenb/sib.conf.example /etc/srsran/sib.conf
sudo cp ~/srsRAN/srsenb/rr.conf.example /etc/srsran/rr.conf
sudo cp ~/srsRAN/srsenb/drb.conf.example /etc/srsran/drb.conf
cd ~/srsRAN/build/

Step-by-Step eNB & UE Setup

Running the eNB

Let’s now launch the eNodeB. The eNB can be launched without root permissions.

cd ~/srsRAN/build/
./srsenb/src/srsenb ~/ran_configurations/enb.conf

The ~/ran_configurations/enb.conf file have the next information:

Add two default via for the S1 and managementt interfaces

If the S1 and managementt interfaces are on different networks, you may want to add two default vias so that both interfaces are visible to the other hosts on its network. To do this, the file is used /etc/iproute2/rt_tables:

# Execute the next command as root
sudo -i
# Add the routing tables for each interface
echo "1 mgmt_interface" >> /etc/iproute2/rt_tables
echo "2 s1_interface" >> /etc/iproute2/rt_tables
# Add the rules for each table
ip rule add from <mgmt_interface_IP>/32 dev eth0 table mgmt_interface
ip rule add from <s1_interface_IP>/32 dev eth1 table s1_interface
ip route add default via <mgmt_interface_gateway> dev eth0 table mgmt_interface
ip route add default via <s1_interface_gateway> dev eth1 table s1_interface

If you want to know the gateway of each interface you can run ip r.

Traffic Generator

To generate traffic to the UE, you can use an iperf server or do a persistent ping to some well-known page. It is important to use the tun_srsue that appears in the VM after the UE is executed. In any case, these are the commands:
```
ping -I tun_srsue 142.250.200.110   # <--- Ping to google
iperf3 -c <server_ip> -p <server_port> -t <number_interactions>     # <--- iperf server (need to start it on before testing)
```
The iperf3 command have:

Variable Value

<server_ip> 35.226.195.247

<server_port> 5001

<number_interactions> 30

Variable	Value
<server_ip>	35.226.195.247
<server_port>	5001
<number_interactions>	30

Troubleshoot

Setup E2E with srsRAN

Error Statement: Failed
Solution
- For a clean tear down, the UE needs to be terminated first, then the eNB.
- eNB and UE can only run once, after the UE has been detached, the eNB needs to be restarted.
- We currently only support a single eNB and a single UE.
Connecting the AGW to the orchestrator on Kubernetes

Error Statement: 400 error after add the rootCA.pem, configure the /etc/hosts and restart services
Solution

A 400 error may occur in the control_proxy service even after adding the rootCA.pem certificate, modifying the /etc/hosts file, and restarting the services. This bug is known and is due to the gateway.crt and gateway.key files being out of date. To solve the problem consider the following steps:
```
# Delete the gateway.* certs
sudo rm /var/opt/magma/certs/gateway.*
# Restart the magma services
sudo service magma@* stop
sudo service magma@magmad restart
```
After this validate the status of the control_proxy service:
```
sudo service magma@control_proxy status
```
