Remova o IP secundário com o NetworkManager / nmcli

2

Eu tentei atribuir um IP estático ao meu servidor Ubuntu 16.04 usando nmcli, que funcionou, mas ainda tem o IP original reservado como um IP "secundário". Não sei como me livrar disso. 10.163.148.36 é o IP original do servidor e 10.163.148.194 é o novo IP para o qual desejo que mude. Eu usei o seguinte comando nmcli para definir o endereço 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'

Observe os dois endereços IP para a interface ens160.

aruba@ubuntu:~$ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1

Por fim, minha configuração do NetworkManager:

aruba@ubuntu:~$ cat /etc/NetworkManager/NetworkManager.conf
[main]
plugins=keyfile,ofono
dns=dnsmasq

[ifupdown]
managed=true

Eu tive a mesma situação e não encontrei nenhuma outra solução, exceto remover o ip antigo usando o comando 'ip addr del', por exemplo:

ip addr del 10.163.148.36/24 dev ens160

Eu resolvi esse problema por:

  1. Removendo o antigo endereço IP / etc / sysconfig / network-scripts / ifcfg-YourConnnectionName
  2. Reinicialize o computador (simplesmente reiniciar o NetworkManager parece não funcionar)

em »Red Hat« a sintaxe seria assim:

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

Você acabou de adicionar um Minus antes de sua propriedade

Poderia funcionar assim no Ubuntu também…?

Isso é o que funcionou para mim no Fedora 29 (provavelmente funciona bem no RHEL / CentOS):

nmcli con mod ens192 ipv4.addresses "" ipv4.gateway ""

Em seguida, basta enviar a interface para selecionar as alterações:

nmcli con down ens192; nmcli con up ens192
