Appendix I: Multiple Server Network Interfaces

This article outlines alternate steps for configuring the network if your server has multiple Network Interface Cards (NICs) installed.

⚙️ Configure the Network

1. On the "Configure the network" screen, select one of the listed network interfaces and click Continue.

2. You should see a "Configuring the network with DHCP" progress message, followed by "Network autoconfiguration has succeeded."

3. ✅ If successful, proceed to Step 5 of the III. - 🐧 Install Debian Linux guide.

3. Click Continue to return to the network interface selection screen.
4. Choose a different network interface from the "Primary network interface" list and repeat the process.

ℹ️ Additional Information

🔌 If all interfaces fail:

• Double-check the physical connections:

• Is the NIC port connected?
• Are there link lights on both the NIC and the switch?
• Is the Ethernet cable securely connected and undamaged?
• Is the network drop connected to your telecommunications room?
• Is a patch cable properly connected between your patch panel and switch?
• Inspect your switch:

• Is DHCP enabled on the port?
• Are any port security policies preventing the server from connecting?

🧑‍💻 Advanced: Verify Network Interface Configurations

If your /etc/network/interfaces file has been manually edited, the ggrock-linux-configurator may fail during installation.

To verify and correct this:

1. Run ip a in the terminal and note each interface name.
2. Run cat /etc/network/interfaces and ensure each active NIC has a corresponding entry.
3. For each NIC not in the DOWN state, add an entry like:

   iface eno3 inet dhcp

4. After updating the file, re-run the ggRock installation.

🛠️ Temporary Workaround

To bypass the issue and continue with the installation:

• Choose "No" when prompted to enable the VM bridge.
• Contact ggCircuit Support via the purple chat bubble in the bottom-right corner of your screen for assistance.
