Configure Static IP on reCamera

This document explains how to configure a static IP address on reCamera (Buildroot system). The configuration includes three steps: edit the config file, set static network parameters, and restart the network service for verification.

Static IP Configuration​

Step 1: Edit the network configuration file​

Run the following command in the reCamera terminal:

sudo vi /etc/network/interfaces

Step 2: Set static IP parameters for eth0​

Configure eth0 as a static interface. Update the values based on your actual network, and make sure the address does not duplicate any other IP address in the same LAN:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
    address 192.168.2.100
    netmask 255.255.255.0
    gateway 192.168.2.1

If you also need to set DNS manually:

echo "nameserver 8.8.8.8" | sudo tee /etc/resolv.conf

Step 3: Restart networking and verify​

Apply the new settings without rebooting:

sudo /etc/init.d/S40network restart

Then verify the eth0 address:

ip addr show eth0

If the output includes your configured address, the static IP is configured successfully.
