+# Network manager in Debian 12
+
+```sh
+sudo apt update
+sudo apt install network-manager
+Start and enable Network Manager as below.
+
+sudo systemctl start NetworkManager.service 
+sudo systemctl enable NetworkManager.service
+```
+
+## Configurare fix IP address
+[link config NetworkManager](https://www.clearlinux.org/clear-linux-documentation/guides/network/assign-static-ip.html) 
+
+Verificare le reti
+
+```sh
+nmcli connection show
+```
+
+dall'output si evince che la rete è ***Supervisor enP3p49s0***
+
+```sh
+NAME                  UUID                                  TYPE      DEVICE    
+Supervisor enP3p49s0  0111eaa1-5253-3749-ab37-68306880a309  ethernet  enP3p49s0 
+lo                    cbd10d14-2994-4875-9f30-78d1435b7da9  loopback  lo        
+Supervisor enP4p65s0  330c6b90-ab43-3eba-a849-a86908742d58  ethernet  --
+```
+
+si possono vedere i file di configurazioni delle reti anche con un list
+```sh
+ls /etc/NetworkManager/system-connections/
+```
+
+con output
+```sh
+'Supervisor enP3p49s0.nmconnection'  'Supervisor enP4p65s0.nmconnection'
+```
+
+il file lo si può editare o visualizzare con 
+
+```console
+sudo nano /etc/NetworkManager/system-connections/'Supervisor enP3p49s0.nmconnection'
+```
+
+per modificare in IP statico con gateway and DNS usare
+
+
+
+ ```sh
+sudo nmcli connection modify "[CONNECTION_NAME]" \
+ipv4.method "manual" \
+ipv4.addresses "[IP_ADDRESS]/[CIDR_NETMASK]" \
+ipv4.gateway "[GATEWAY_IP_ADDRESS]" \
+ipv4.dns "[PRIMARY_DNS_IP],[SECONDARY_DNS_IP]"
+```
+quindi nel nostro caso
+
+```sh
+sudo nmcli con mod "Supervisor enP3p49s0" ipv4.method manual ipv4.addresses 192.168.1.4/24 ipv4.gateway 192.168.1.1 ipv4.dns 8.8.8.8,8.8.4.4
+```
+
+poi fare il rebbot di sistema
+
+```sh
+sudo reboot now
+```
+
