Local IT Guide for Ethernet (LAN), WI-FI (WLAN)
or optional 3G (Mobile Network)
The SpiroSphere system offers data transfer functionality via Ethernet (LAN), Wi-Fi (WLAN) or
optional 3G (Mobile Network) which requires access to the Internet. 3G is only applicable for the
optional 3G module.
Since the SpiroSphere system would for Ethernet (LAN) or WIFI (WLAN) be part of your local
network, this guide explains how the system behaves and needs to be congured.
SpiroSphere is compliant to HIPAA regulations. There is no direct access to the operating system.
Where User Management is enabled the responsible user of the data has to be able to control the
access to the system.
How to con¿gure Ethernet, WiFi Access or optional 3G (Mobile Network)
In the "Settings & Tools" menu of the SpiroSphere system in the sub menu "Communication"
Ethernet (LAN), Wi-Fi (WLAN) (or 3G Mobile Network) can be congured. The MAC addresses
and IP addresses are visible within the "Settings & Tools" / "About Device" Information Screen.
A check connection function helps to verify the network setup. A more detailed description of the
possible conguration settings in the Settings & Tools menu can be found in the chapter "Settings
& Tools" / "Communication" in this manual.
The following information describes the network settings and behavior of the SpiroSphere system.
How is SpiroSphere con¿gured?
• Linux (32bit)
• No Third Party Application can be installed
• No Access to operating system
• No Access to an open web browser (no surng)
• No Access to Bootloader
• No Network Registration (DNS)
• Firewall Activated (iptables), blocking all incoming trafc (except ping, ssh, DNS and DHCP,
SMTP, FTP), preventing outgoing trafc except from authorized applications.
• Connected Media (USB) are checked against checksums before any content is accepted. No
content form a USB stick is executed.
Which endpoints are accessed?
Data Transfer Check Normal Operation
• DNS (Local) • DNS (Local)
• DHCP (Local) • DHCP (Local)
• Ping (localhost) • Ping (ERT)
• Ping (ERT) • FTP (Local)
• FTP (Local) • SMTP (Local)
How the system behaves?
The network interfaces are only used when data needs to be transmitted.
Ideal Network Setup?
To satisfy common local network policies, a virtual or physically separated network with outgoing
internet access is recommended. SpiroSphere does not require this separation.
How is the system updated?
Software components of the SpiroSphere system are made available by ERT.
