===== Configure Static IP with nmcli (via SSH) =====

This document explains how to set a static IP address on an Ethernet interface using `nmcli`, assuming you are connected to the machine via SSH.

==== Assumptions ====
  * The network interface is '''enp2s0'''
  * The desired static IP is '''192.168.0.31'''
  * The default gateway is '''192.168.0.1'''
  * DNS servers will be '''8.8.8.8''' and '''1.1.1.1'''

==== Steps ====

=== 1. Create a new static IP connection ===
<code bash>
sudo nmcli con add type ethernet ifname enp2s0 con-name static-ip autoconnect no ip4 192.168.0.31/24 gw4 192.168.0.1
</code>

=== 2. Set DNS servers ===
<code bash>
sudo nmcli con mod static-ip ipv4.dns "8.8.8.8 1.1.1.1"
</code>

=== 3. Activate the new connection ===
**Note:** This may temporarily disconnect the SSH session. Reconnect using the static IP:
<code bash>
sudo nmcli con up static-ip
</code>

=== 4. (Optional) Delete the old DHCP connection ===
Once confirmed that the static IP connection works:
<code bash>
sudo nmcli con delete "Wired connection 1"
</code>

=== 5. Ensure the connection starts automatically at boot ===
<code bash>
sudo nmcli con mod static-ip connection.autoconnect yes
</code>

=== 6. Final verification ===
<code bash>
nmcli con show
ip addr show enp2s0
</code>

==== Expected result ====
The machine will use the static IP '''192.168.0.31''' permanently, even after reboots, without relying on DHCP.
