This is an optional step, if you plan to manage your network using other tools. At this point, the system is very minimal - a great base for a customizing a special-case system, but not quite suitable for typical use. The 'parabola-base' meta-package contains several useful tools that were once standard, before the minimalist 'base' meta-package was introduced as the new standard base system.
It includes the midnight-commander mc file manager, the vi and nano text editors, a man-page viewer, and support utilities for networking and file-systems, for examples. If you have a btrfs root, you probably want to install also btrfs-progs. For f2fs, install f2fs-tools. Note that this section only describes the essential pre-requisites for graphical Parabola systems. The commands below will not install any X-server , display manager , window manager , or desktop environment.
There are many possible combinations to choose from; but that is beyond the scope of this guide. There are no special requirements during the initial install for using a graphical desktop with a Parabola systemd system. This section describes the bare minimum requirements for using a graphical desktop with a Parabola OpenRC system.
The openrc-desktop package group installs essential software for graphical desktop environments. Obviously, systemd is not an essential 'base' package on non-systemd Parabola systems; and is not installed by default. However, many GUI programs expect that systemd and it's dependencies are installed, and would have un-met dependencies if systemd or a substitute is not installed.
There are multiple systemd substitutes; so you will need to choose one. It can grant privileges for desktop operations, such as powering off and mounting USB devices, and also provides systemd stub libraries, and depends on the same packages as 'systemd', in order to satisfy GUI programs which refuse to run otherwise.
If you're using wifi-menu to connect, you'll also need the dialog package:. Generate an fstab with the following command if you prefer to use UUIDs or labels, add the -U or -L option, respectively :. Your computer's hostname can be anything that you like, consisting of letters a-z, digits , and hyphens '-' eg: alices-laptop. The system hostname is mainly informational, making it easier to distinguish computers on your local network.
This name will also appear in your shell prompt - eg:. If you have installed multiple kernels, run the same command again for each kernel. If you are using TalkingParabola and need start speech support when you boot the system, you will need to do:. If you are running OpenRC rather than systemd, make sure that the nonsystemd repo is enabled. See Pacman and Official Repositories for details. Also consider using Pacman2pacman , a peer to peer package system, in order to reduce load on official Parabola servers.
Most casual desktop users would rarely need to interact with the service manager; but it is a good idea to learn the basics. The process is the same, now while in the chroot, and afterward during normal use. Interaction with systemd is done through the systemctl command. Read a:systemd Basic systemctl usage for more information.
Interaction with OpenrRC is done through the rc-update , rc-service , and rc-status commands. Newly installed services will need to be added to specific runlevels.
The 'default' runlevel is the only one that most users will need. Note, however, that essential services are enabled by default e. You will need to "chroot" into the target system first, in order to accomplish this. That will normally not be necessary, once the system is installed and running. Set a root password with passwd :. See User management for advanced examples of users and groups. See the OpenRC article for details. Additional networking configuration may be needed for graphical wifi managers and other network management tools.
See a:Network configuration and Wireless Setup ; or ask for help on IRC, on the web forum , or on the mailing list , if you would like suggestions. There are some subtle caveats to be aware of regarding OpenRC, in some system configurations, which have not been mentioned in this guide. The OpenRC article has some trouble-shooting advice for the most common problems. If you have a problem initially, with using your new OpenRC system, please read that article, first before reporting bugs. Otherwise, the fresh system is already up-to-date.
Regardless, it is always safe to upgrade the system; and it is recommended to do so at least once per month. Before upgrading the system for the first time, or anytime when a few months has past between upgrades, ensure that you have the current key-rings first:. Exit the chroot, then un-mount any partitions which you mounted in the "Mount the partitions" step. Then you can reboot and login to the new system normally. Welcome to Fosstopia.

Note: The install procedure varies in several ways, depending on the init system that you choose. If you have no preference, SystemD is the recommended option. Throughout this guide, pay special attention to sections which distinguish between SystemD and OpenRC systems.
Warning: The following command will erase everything that is currently on the USB drive. Warning: It is very important to use the correct value for [usb device file] to avoid overwriting other storage devices. Warning: Check that the system clock is correct at this point, otherwise GPG key files' timestamps will be in the future and key-rings installation won't work.
Note: If you are installing an OpenRC system, from one of the systemd LiveISOs, ensure that pacman is subscribed to the nonsystemd package repo before beginning the install process. Note: we need elogind since it provides 'systemd' and libelogind provides 'systemd-libs' , which is necessary for packages that depend on it.
Note: we need udev-init-scripts to start eudev at boot. Astra, Hotbird, Eutelsat, sono i nomi dei satelliti geostazionari a disposizione degli europei. Questo segnale viene poi instradato attraverso un cavo coassiale verso un decoder associato ad un televisore che ritraduce il segnale elettrico in immagini. I satelliti europei sono posizionati in un'orbita geostazionaria verso sud. Assicurati che lo spazio sia sgombro e che non ci sia alcuno ostacolo che possa intralciare la ricezione delle onde alberi , edifici.
Misura la distanza tra il tuo impianto e il decoder. Fissa la piastra di supporto con dei tasselli e un trapano a percussione. Assembla il braccio e la testa LNB e fissa il tutto sulla parabola. Procedi alla regolazione e al fissaggio, tenendo conto di questi criteri. Sul web puoi trovare diversi siti che ti permettono di trovare l'elevazione e l'azimut partendo dalle coordinate del luogo dove vuoi posizionare l'antenna e dalla posizione del satellite in gradi.
Stendi il cavo coassiale fino al decoder. Monta i connettori F su entrambi i lati del cavo e collegali. Dopo aver collegato il decoder al televisore, accendilo e impostalo sul canale desiderato a seconda del satellite per esempio, per la regolazione del satellite Astra, imposta il decoder su AV.
I professionisti possiedono dispositivi che permettono loro di regolare la parabola da soli. Una volta individuato verso quale satellite la tua parabola deve puntare, orientala con una bussola nella direzione data. Una volta ottenuto il giusto puntamento, stringi le staffe.
Esistono delle applicazioni per tablet e smartphone utili per la regolazione delle parabole. Queste applicazioni, supportate da una bussola virtuale e spesso fornite dai proprietari dei satelliti, mostrano:. Una volta fissata la parabola, non dimenticarti di fissare il cavo coassiale che arriva al decoder.
Evita curve e bruschi cambi di direzione. In caso di passaggio attraverso le finestre , utilizza dei raccordi piatti passafinestra per non danneggiare il cavo. Per installare una parabola dovrai saper utilizzare un trapano , scegliere dei tasselli adatti al supporto e saper utilizzare una bussola. Inoltre, dovrai realizzare dei semplici collegamenti cavo coassiale e spine e stendere i cavi.
In pensione, ho sistemato e attrezzato un laboratorio in cui realizzo sculture metalliche: sono riuscito a combinare e sistemare un angolo di paradiso dove amo lasciare libero spazio alla mia immaginazione.
