Ho provato ad assegnare un IP statico al mio server Ubuntu 16.04 usando nmcli, che ha funzionato ma ha ancora l'IP originale riservato come IP "secondario". Non sono sicuro di come liberarmene. 10.163.148.36 è l'IP originale del server e 10.163.148.194 è il nuovo IP a cui voglio che passi. Ho usato il seguente comando nmcli per impostare l'indirizzo IP:
nmcli connection modify 'Wired connection 1' ipv4.addresses '10.163.148.194/24' ipv4.gateway '10.163.148.2' ipv4.method 'manual' ipv4.ignore-auto-dns 'yes' connection.autoconnect 'yes' ipv4.dns '10.10.10.10 10.20.10.10'
Prendere nota dei due indirizzi IP per l'interfaccia ens160.

Infine, la mia configurazione di NetworkManager:
[email protected]:~$ cat /etc/NetworkManager/NetworkManager.conf
[main]
plugins=keyfile,ofono
dns=dnsmasq
[ifupdown]
managed=true
Risposta accettata:
in »Red Hat« la sintassi sarebbe questa:
nmcli con mod "Wired connection 1" -ipv4.addresses "10.163.148.194"
Devi solo aggiungere un meno prima della tua proprietà
Potrebbe funzionare così anche in Ubuntu...?
