Network Management
|
|
==================
|
|
|
|
Proxmox Backup Server provides both a web interface and a command line tool for
|
|
network configuration. You can find the configuration options in the web
|
|
interface under the **Network Interfaces** section of the **Configuration** menu
|
|
tree item. The command line tool is accessed via the ``network`` subcommand.
|
|
These interfaces allow you to carry out some basic network management tasks,
|
|
such as adding, configuring, and removing network interfaces.
|
|
|
|
.. note:: Any changes made to the network configuration are not
|
|
applied, until you click on **Apply Configuration** or enter the ``network
|
|
reload`` command. This allows you to make many changes at once. It also allows
|
|
you to ensure that your changes are correct before applying them, as making a
|
|
mistake here can render the server inaccessible over the network.
|
|
|
|
To get a list of available interfaces, use the following command:
|
|
|
|
.. code-block:: console
|
|
|
|
# proxmox-backup-manager network list
|
|

|
|
|
|
To add a new network interface, use the ``create`` subcommand with the relevant
|
|
parameters. For example, you may want to set up a bond, for the purpose of
|
|
network redundancy. The following command shows a template for creating the bond shown
|
|
in the list above:
|
|
|
|
.. code-block:: console
|
|
|
|
# proxmox-backup-manager network create bond0 --type bond --bond_mode active-backup --slaves ens18,ens19 --autostart true --cidr x.x.x.x/x --gateway x.x.x.x
|
|
|
|
You can make changes to the configuration of a network interface with the
|
|
``update`` subcommand:
|
|
|
|
.. code-block:: console
|
|
|
|
# proxmox-backup-manager network update bond0 --cidr y.y.y.y/y
|
|
|
|
You can also remove a network interface:
|
|
|
|
.. code-block:: console
|
|
|
|
# proxmox-backup-manager network remove bond0
|
|
|
|
The pending changes for the network configuration file will appear at the bottom of the
|
|
web interface. You can also view these changes, by using the command:
|
|
|
|
.. code-block:: console
|
|
|
|
# proxmox-backup-manager network changes
|
|
|
|
If you would like to cancel all changes at this point, you can either click on
|
|
the **Revert** button or use the following command:
|
|
|
|
.. code-block:: console
|
|
|
|
# proxmox-backup-manager network revert
|
|
|
|
If you are happy with the changes and would like to write them into the
|
|
configuration file, select **Apply Configuration**. The corresponding command
|
|
is:
|
|
|
|
.. code-block:: console
|
|
|
|
# proxmox-backup-manager network reload
|
|
|
|
.. note:: This command and corresponding GUI button rely on the ``ifreload``
|
|
command, from the package ``ifupdown2``. This package is included within the
|
|
Proxmox Backup Server installation, however, you may have to install it yourself,
|
|
if you have installed Proxmox Backup Server on top of Debian or a Proxmox VE
|
|
version prior to version 7.
|
|
|
|
You can also configure DNS settings, from the **DNS** section
|
|
of **Configuration** or by using the ``dns`` subcommand of
|
|
``proxmox-backup-manager``.
