Метка: ipv6 disable

Fedora 30. Настройка сети, отключение ipv6

1. Устанавливаем статический  IP адрес на сервер. ( Замените [ens2] на свое наименование сетевого интерфейса )

# set hostname

[root@localhost ~]#

hostnamectl set-hostname dlp.srv.world
# display devices

[root@localhost ~]#

nmcli device
DEVICE  TYPE      STATE      CONNECTION
ens2    ethernet  connected  ens2
lo      loopback  unmanaged  --
# set IPv4 address

[root@localhost ~]#

nmcli connection modify ens2 ipv4.addresses 10.0.0.30/24
# set gateway

[root@localhost ~]#

nmcli connection modify ens2 ipv4.gateway 10.0.0.1
# set DNS

[root@localhost ~]#

nmcli connection modify ens2 ipv4.dns 10.0.0.1
# set manual for static setting (it’s [auto] for DHCP)

[root@localhost ~]#

nmcli connection modify ens2 ipv4.method manual
# restart the interface and reload the settings

[root@localhost ~]#

nmcli connection down ens2; nmcli connection up ens2
Connection 'ens2' successfully deactivated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/1)

2. Отключить IPv6, если не нужен, можно так:

[root@localhost ~]#

vi /etc/default/grub
# line 7: add

GRUB_CMDLINE_LINUX=»

ipv6.disable=1

resume=/dev/mapper/fedora-swap…..

# apply changes

[root@localhost ~]#

grub2-mkconfig -o /boot/grub2/grub.cfg

[root@localhost ~]#

reboot
