Ubuntu – Odebrat sekundární IP pomocí Networkmanager / Nmcli?

Pokusil jsem se přiřadit statickou IP svému serveru Ubuntu 16.04 pomocí nmcli, což fungovalo, ale stále má původní IP vyhrazenou jako „sekundární“ IP. Nejsem si jistý, jak se toho zbavit. 10.163.148.36 je původní IP serveru a 10.163.148.194 je nová IP, na kterou chci, aby se přepnul. K nastavení IP adresy jsem použil následující příkaz nmcli:

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'

Všimněte si dvou IP adres pro rozhraní ens160.

[email protected]:~$ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1

Nakonec moje konfigurace NetworkManageru:

[email protected]:~$ cat /etc/NetworkManager/NetworkManager.conf
[main]
plugins=keyfile,ofono
dns=dnsmasq

[ifupdown]
managed=true

Přijatá odpověď:

v »Red Hat« bude syntaxe vypadat takto:

nmcli con mod "Wired connection 1" -ipv4.addresses "10.163.148.194"

Stačí přidat mínus před vaši vlastnost

Mohlo by to takto fungovat i v Ubuntu…?
