In order to use the additional addresses on the server<\/a> the package “iproute” and service program “ip” are needed. Configuration with alias interfaces (such as eth0:1, eth0:2 etc.) are outdated and should no longer be used.<\/span><\/p>\n

<\/p>\n

To add an address please run:<\/span><\/p>\n

$ ip addr add 10.4.2.1\/27 dev enp2s0\u00a0<\/strong><\/em> <\/span><\/p>\n

10.4.2.1 – additional IP,
\n<\/span><\/span>enp2s0 – name interfaces.<\/span><\/p>\n

To determine the name of the network interface, run:<\/span><\/p>\n

$ ifconfig<\/strong><\/em><\/span><\/p>\n

This method is the simplest and fastest, however, after rebooting the server, the settings are not saved and the additional IP will not be available.<\/span><\/p>\n

To permanently configure an additional IP, add the following lines to the \/etc\/network\/interfaces<\/em> file under the appropriate interface (for example, \u201cenp2s0\u201d):<\/span><\/p>\n

up ip addr add 10.4.2.1\/32 dev enp2s0
\n<\/strong><\/em><\/span>down ip addr del 10.4.2.1\/32 dev enp2s0<\/strong><\/em><\/span><\/p>\n


\n<\/strong><\/em>The config should look something like this:<\/span><\/p>\n

source \/etc\/network\/interfaces.d\/*<\/strong><\/em><\/span><\/p>\n

auto lo<\/em><\/strong><\/span>
\niface lo inet loopback<\/em><\/strong><\/span>
\niface lo inet6 loopback<\/em><\/strong><\/span><\/p>\n

auto enp2s0<\/em><\/strong><\/span>
\niface enp2s0 inet static<\/em><\/strong><\/span>
\naddress 10.4.0.0<\/em><\/strong><\/span>
\nnetmask 255.255.255.224<\/em><\/strong><\/span>
\ngateway 148.251.82.97<\/em><\/strong><\/span>
\n# route 148.251.82.96\/27 via 148.251.82.97<\/em><\/strong><\/span>
\nup route add -net 148.251.82.96 netmask 255.255.255.224 gw 148.251.82.97 dev enp2s0<\/em><\/strong><\/span><\/p>\n

up ip addr add 10.4.2.1\/27 dev enp2s0<\/em><\/strong><\/span>
\ndown ip addr del 10.4.2.1\/27 dev enp2s0<\/em><\/strong><\/span><\/p>\n

iface enp2s0 inet6 static<\/em><\/strong><\/span>
\naddress 2a01:4f8:202:5264::2<\/em><\/strong><\/span>
\nnetmask 64<\/em><\/strong><\/span>
\ngateway fe80::1<\/em><\/strong><\/span><\/p>\n

To apply the settings, restart the service:<\/span>
\n<\/span><\/span><\/p>\n

$ service networking restart<\/strong><\/em><\/span><\/p>\n

Network setup through systemd-networkd.<\/span><\/strong><\/p>\n

Starting with versions of Debian 8 and Ubuntu 16.04, it is possible to use the systemd-networkd daemon. You need systemd version 210 and higher. You can check the version using the command:<\/span><\/p>\n

$ systemctl –version<\/strong><\/em><\/span><\/p>\n

If the network is configured using \/etc\/network\/<\/em>, you must rename the interface file under a different name so that it is not used after setting up systemd-networkd:<\/span><\/p>\n

$ mv \/etc\/network\/interfaces \/etc\/network\/interfaces.save<\/strong><\/em><\/span><\/p>\n

Then add systemd-networkd to the system startup, but do not start the service, because the network is not yet defined in systemd-networkd:<\/p>\n

$ systemctl enable systemd-networkd<\/strong><\/em><\/span><\/p>\n

All configuration files are stored in \/etc\/systemd\/network<\/em>. Please note that case is important in configuration files.<\/span><\/p>\n

Creat file enp2s0.network:<\/span>
\n<\/span>
\n<\/span>[Match]
\nName=enp2s0<\/strong><\/em><\/span><\/p>\n


\n<\/strong><\/em>[Network]
\nAddress=10.4.0.0\/27
\nAddress=10.4.2.1\/27
\n<\/strong><\/em>\u00a0Gateway=148.251.82.97<\/strong><\/em><\/span><\/p>\n

Address=10.4.0.0\/27 – main IP server,
\n<\/span>Address=10.4.2.1\/27 – additional IP.<\/span><\/span><\/p>\n

Star systemd-networkd:<\/span>
\n<\/span>
\n<\/span>$ systemctl start systemd-networkd<\/strong><\/em><\/span><\/p>\n

Done!<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
