This bundle contains the basic core OS components.
|
||||
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 you should follow the next steps:
|
||||
To configure a static IP, follow these steps:
|
||||
|
||||
#. Create file :file:`/etc/systemd/network/50-static.network`. If a directory
|
||||
does not exist, please create it.
|
||||
#. Create the file: :file:`/etc/systemd/network/50-static.network` If the
|
||||
path does not exist, create it.
|
||||
|
||||
#. The minimum lines the :file:`50-static.network` file should contain are::
|
||||
#. Add, at the very least, the following lines to the
|
||||
:file:`50-static.network` file:
|
||||
|
||||
[Match]
|
||||
Name=<device_name>
|
||||
.. code-block:: console
|
||||
|
||||
[Network]
|
||||
Address=<A static IPv4 or IPv6 address and its prefix length, separated by a "/" character>
|
||||
Gateway=<The gateway address>
|
||||
[Match]
|
||||
Name=<device_name>
|
||||
|
||||
The *<device_name>* is your network device name (i.e. enp1s0 or enp0s25).
|
||||
[Network]
|
||||
Address=<Provide a static IPv4 or IPv6 address with its
|
||||
prefix length. Separate them with the "/" character.>
|
||||
Gateway=<The gateway's address>
|
||||
|
||||
#. If you want to add more options you can consult the
|
||||
`systemd network configuration`_ manual.
|
||||
The `<device_name>` is your network device name, for example: enp1s0 or
|
||||
enp0s25.
|
||||
|
||||
#. Restart *systemd-networkd* service using::
|
||||
#. To add more options you can consult the `systemd network configuration`_
|
||||
manual.
|
||||
|
||||
# systemctl restart systemd-networkd
|
||||
|
||||
or restart Clear Linux.
|
||||
|
||||
#. Check new IP with::
|
||||
|
||||
# ip addr
|
||||
#. Restart the *systemd-networkd* service with the following command:
|
||||
|
||||
|
||||
Setting Time
|
||||
.. 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 utilizes **systemd-timesyncd.service** to sync time.
|
||||
Default :abbr:`NTP (Network Time Protocol)` servers are
|
||||
configured as *time1.google.com, time2.google.com, time3.google.com, and
|
||||
time4.google.com*. It is not possible to set the time manually, via
|
||||
*timedatectl*
|
||||
or to use RTC mode. In the event that those servers cannot be reached and the
|
||||
time is incorrect on your system, try these steps:
|
||||
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:
|
||||
|
||||
#. Make sure that you've set your timezone:
|
||||
#. Set the timezone, for example, Pacific time:
|
||||
|
||||
* If you at Pacific time::
|
||||
.. code-block:: console
|
||||
|
||||
timedatectl set-timezone America/Los_Angeles
|
||||
timedatectl set-timezone America/Los_Angeles
|
||||
|
||||
or you can choose a preferred timezone
|
||||
To see a list of timezones, use the following command:
|
||||
|
||||
* To see a list of timezones, do::
|
||||
.. code-block:: console
|
||||
|
||||
timedatectl list-timezones | grep <locale>
|
||||
timedatectl list-timezones
|
||||
|
||||
#. Create :file:`/etc/systemd/` directory
|
||||
#. Go to the :file:`/etc/systemd/` directory, if it does not exist, create
|
||||
it.
|
||||
|
||||
#. Open your chosen editor and type into the
|
||||
:file:`/etc/systemd/timesyncd.conf` file::
|
||||
#. Create the :file:`/etc/systemd/timesyncd.conf` file and enter the
|
||||
following lines:
|
||||
|
||||
[Time]
|
||||
NTP=<Preferred Server>
|
||||
FallbackNTP=<backup server 1> <backup server 2>
|
