EDFN Installation Guide
The External Data Feeder for NFO (EDFN) is required for ingesting Cloud Flow Logs (AWS, Azure, GCP) or for security architectures where NFO is isolated from the internet.
If you installed NFO version 2.7 or higher, EDFN is already installed on your NFO host. You only need this guide if you require a standalone EDFN instance on a separate server.
System Requirements & Supported Platforms
- System: 4 CPU Cores, 8GB RAM.
- Linux: Kernel 2.17+ on systemd-based distributions (Rocky Linux 8/9, RHEL 7/8/9, Ubuntu 20.04+, Debian 9+, Oracle Linux 7+).
- Windows: Windows Server 2016, 2019, 2022.
Required Network Ports
For NetFlow Optimizer and the External Data Feeder for NFO (EDFN) to function correctly, ensure the following network connectivity is established.
Management & Internal Communication
The following port is the primary management channel and must be open on the NFO host to allow incoming connections from the EDFN service:
| Port | Protocol | Direction | Description |
|---|---|---|---|
| 8443 | TCP | Inbound to NFO | Critical: Management UI and secure EDFN-to-NFO communication (HTTPS). |
Outbound Agent Communication
The EDFN service does not "listen" on the ports below; rather, it initiates outbound connections to external data sources. The specific ports required depend entirely on the Enrichment Agents you enable:
- Internet Communication: Most cloud-based agents (e.g., Threat Intel, AWS/Azure, GeoIP updates) require outbound access on TCP 80 and TCP 443.
- Infrastructure Agents: Other agents may require specific outbound ports depending on the service being polled (e.g., TCP 5985/5986 for WinRM/Active Directory, or TCP/UDP 443 for VMware vCenter).
Installation Instructions
Linux
EDFN installation default directory is /opt/nfi-updater.
- Download the RPM or TAR package.
- Install (RPM):
rpm -ihv nfi-updater-<version>.x86_64.rpm
- Install (TAR):
tar zxvf nfi-updater-<version>.tar.gz
./setup.sh -i
The setup.sh script includes an optional --doNotStartServices parameter, which prevents the EDFN service from starting automatically after installation. This is useful when EDFN configuration is copied from one machine to another or installing the service as non-root.
- Start Service:
Unless
--doNotStartServicesparameter is used, EDFN service is started automatically. You can check if it is running using this command:
systemctl status nfi_updd
If it is not running, start it using this command:
systemctl start nfi_updd
Windows
- Download and launch the
.exe.zipinstaller. - Unzip the installer.
- Follow the setup wizard.
- Verify: Open
services.mscand ensure External Data Feeder for NFO is "Running."
Post Installation Steps
If External Data Feeder for NFO is installed on a separate server, or if you have several EDFNs connected to one NFO, perform the following:
-
Stop EDFN service
- for Linux OSes which support systemd use command
systemctl stop nfi_updd - for Linux OSes which support OpenRC use command
rc-service nfi_updd stop - for other Linux OSes use command
service nfi_updd stop - for Windows OSes use Microsoft Management Console snap-in "Services"
- for Linux OSes which support systemd use command
-
Change
uriparameter in updater.properties file located in/opt/nfi-updater/conf(In WindowsC:\Program Files\NetFlow Logic\NetFlow Integrator Updater\conf) to IP address or DNS name of NetFlow Optimizeruri = https://<nfo-host>:8443 -
If this is your second EDFN instance, set a unique EDFN identifier in
uiduid = EDFN2 -
Copy Java KeyStore and TrustStore from EDFN installed with NFO ($EDFN1_HOME) to EDFN installed on a separate machine ($EDFN2_HOME)
| From | To |
|---|---|
| $EDFN1_HOME/conf/.updater_keystore | $EDFN2_HOME/conf/.updater_keystore |
| $EDFN1_HOME/conf/.updater_truststore | $EDFN2_HOME/conf/.updater_truststore |
-
Start EDFN service
- for Linux OSes which support systemd use command
systemctl start nfi_updd - for Linux OSes which support OpenRC use command
rc-service nfi_updd start - for other Linux OSes use command
service nfi_updd start - for Windows OSes use Microsoft Management Console snap-in "Services"
- for Linux OSes which support systemd use command
