Procedure for adding relays to Medulla Dedicated SaaS

1. Setting up the server

Required settings:

  • OS: Debian 12.x
  • Architecture: x86-64
  • CPU: 4 vCPUs
  • RAM: 8 GB
  • Storage
  • /: 20 GB – EXT4
  • /var: ≥ 400 GB – XFS (Or a dedicated mount point on an external array/volume)

2. Creating a user

Create the user "medulla" and grant them sudo privileges.

3. Installing the SSH key

The SSH public key provided as an attachment must be added to:

/home/medulla/.ssh/authorized_keys

4. Opening network ports

Traffic must be allowed in both directions between:

  • Medulla Server
  • Relay (your server)
4.1. Medulla Server → Relay Traffic

Port | Description

  • 5269 | TCP / XMXPP
  • 22 | TCP / SSH
  • 22000 | TCP / Syncthing
  • 8081 | TCP / HTTP(S)
  • 9990 | TCP / XML RPC HTTPS
4.2. Relay Stream → Medulla Server

Port | Description

  • 5269 | TCP / XMXPP
  • 22 | TCP / SSH
  • 22000 | TCP / Syncthing
  • 8443 | TCP / HTTPS
  • 22067 | TCP / BEP-Relay/TLS
  • 9999 | TCP / XML RPC/HTTPS
  • 7080 | TCP / XML RPC/HTTPS

5. Information to Provide

The team must provide us with:

  • Create the entity you wish to dedicate to the relay in ITSM (only if you want an entity different from the parent entity).
  • Confirmation that the above network ports have been opened.
  • Confirmation that the SSH key has been added to the relay server.
  • The password for the "medulla" user with passwordless sudo privileges.
  • The FQDN of your relay server

6. Continuation of the installation

Once the machine is ready, we will perform the full software installation via Ansible.

A Medulla agent will be automatically generated to connect the workstations to this relay.
