#######
|
|
|
|
This bundle contains the basic core components of the operating system.
|
|
|CLOSIA| relies on `systemd` to provide the basic OS components. The
|
|
`systemd` package contains solutions for:
|
|
|
|
* Service management
|
|
* Basic network management
|
|
* Hostname management
|
|
* Time synchronization management
|
|
* Boot control management
|
|
* Journal management
|
|
|
|
Additionally, `os-core` includes the `util-linux` and `coreutils` packages to
|
|
provide a set of basic Linux\* command line tools such as `ls`, `cp`, `rm`,
|
|
etc.

Static IP
|
|
=========
|
|
|
|
To configure a static IP, follow these steps:
|
|
|
|
#. Create the file: :file:`/etc/systemd/network/50-static.network` If the
|
|
path does not exist, create it.
|
|
|
|
#. Add, at the very least, the following lines to the
|
|
:file:`50-static.network` file:
|
|
|
|
.. code-block:: console
|
|
|
|
[Match]
|
|
Name=<device_name>
|
|
|
|
[Network]
|
|
Address=<Provide a static IPv4 or IPv6 address with its
|
|
prefix length. Separate them with the "/" character.>
|
|
Gateway=<The gateway's address>
|
|
|
|
The `<device_name>` is your network device name, for example: enp1s0 or
|
|
enp0s25.
|
|
|
|
#. To add more options you can consult the `systemd network configuration`_
|
|
manual.
|
|
|
|
#. Restart the *systemd-networkd* service with the following command:
|
|
|
|
|
|
.. code-block:: console
|
|
|
|
# systemctl restart systemd-networkd
|
|
|
|
Alternatively, restart |CL|.
|
|
|
|
#. Check the new IP with the following command:
|
|
|
|
.. code-block:: console
|
|
|
|
# ip addr
|
|
|
|
|
|
Setting time
|
|
============
|
|
|
|
Clear Linux uses the `systemd-timesyncd.service` service to synchronize the
|
|
system's time. Default :abbr:`NTP (Network Time Protocol)` servers are
|
|
configured, for example: `time1.google.com`, `time2.google.com`,
|
|
`time3.google.com`, and `time4.google.com`. Manually setting the time via
|
|
`timedatectl` or using RTC mode is not possible. If those servers cannot be
|
|
reached and the system time is incorrect, follow these steps:
|
|
|
|
#. Set the timezone, for example, Pacific time:
|
|
|
|
.. code-block:: console
|
|
|
|
timedatectl set-timezone America/Los_Angeles
|
|
|
|
To see a list of timezones, use the following command:
|
|
|
|
.. code-block:: console
|
|
|
|
timedatectl list-timezones
|
|
|
|
#. Go to the :file:`/etc/systemd/` directory, if it does not exist, create
|
|
it.
|
|
|
|
#. Create the :file:`/etc/systemd/timesyncd.conf` file and enter the
|
|
following lines:
|
|
|
|
.. code-block:: console
|
|
|
|
[Time]
|
|
NTP=<Preferred Server>
|
|
FallbackNTP=<backup server 1> <backup server 2>
|
|
|
|
#. Restart the timesync daemon with the following command:
|
|
|
|
.. code-block:: console
|
|
|
|
# systemctl restart systemd-timesyncd
