1. D-Bus a D-Bus FAQ Szerint D-Bus Egy Interprocessz-Kommunikációs Protokoll, És Annak Referenciamegvalósítása
Az Udev / D-Bus rendszer - a modern asztali Linuxok alapja A D-Bus rendszer minden modern Linux disztribúcióban jelen van, sőt mára már a Linux, és más UNIX jellegű, sőt nem UNIX rendszerek (különösen a desktopon futó változatok) egyik legalapvetőbb technológiája, és az ismerete a rendszergazdák számára lehetővé tesz néhány rendkívül hasznos trükköt, az alkalmazásfejlesztőknek pedig egyszerűen KÖTELEZŐ ismerniük. Miért ilyen fontos a D-Bus? Mit csinál? D-Bus alapú technológiát teszik lehetővé többek között azt, hogy közönséges felhasználóként a kedvenc asztali környezetünkbe bejelentkezve olyan feladatokat hajtsunk végre, amiket a kernel csak a root felasználónak engedne meg. Felmountolunk egy USB meghajtót? NetworkManagerrel konfiguráljuk a WiFi-t, a 3G internetet vagy bármilyen más hálózati csatolót, és kapcsolódunk egy hálózathoz? Figyelmeztetést kapunk a rendszertől, hogy új szoftverfrissítések érkeztek, majd telepítjük ezeket? Hibernáljuk, felfüggesztjük a gépet? A legtöbb esetben ma már D-Bus alapú technológiát használunk ilyen esetben. A D-Bus lehetővé teszi, hogy egymástól függetlenül, jellemzően más UID alatt indított szoftverösszetevők szabványos és biztonságos módon igénybe vegyék egymás szolgáltatásait. Ha valaha lesz a Linuxhoz professzionális desktop tűzfal vagy vírusirtó megoldás, a dolgok jelenlegi állasa szerint annak is D- Bus technológiát kell használnia. A D-Bus technológia legfontosabb ihletője a KDE DCOP rendszere volt, és mára a D-Bus leváltotta a DCOP-ot, csakúgy, mint a Gnome Bonobo technológiáját. 1. D-Bus A D-Bus FAQ szerint D-Bus egy interprocessz-kommunikációs protokoll, és annak referenciamegvalósítása. Ezen referenciamegvalósítás egyik összetevője, a libdbus könyvtár a D- Bus szabványnak megfelelő kommunikáció megvalósítását segíti. Egy másik összetevő, a dbus- daemon a D-Bus üzenetek routolásáért, szórásáért felelős. -
Introduction Use Runit with Traditional Init (Sysvinit)
2021/07/26 19:10 (UTC) 1/12 Runit Runit Introduction runit is a UNIX init scheme with service supervision. It is a cross-platform Unix init scheme with service supervision, a replacement for sysvinit, and other init schemes and supervision that are used with the traditional init. runit is compatible with djb's daemontools. In Unix-based computer operating systems, init (short for initialization) is the first process started during booting of the computer system. Init is a daemon process that continues running until the system is shut down. Slackware comes with its own legacy init (/sbin/init) from the sysvinit package, that used to be included in almost all other major Linux distributions. The init daemon (or its replacement) is characterised by Process ID 1 (PID 1). To read on the benefits of runit, see here: http://smarden.org/runit/benefits.html * Unless otherwise stated, all commands in this article are to be run by root. Use runit with traditional init (sysvinit) runit is not provided by Slackware, but a SlackBuild is maintained on https://slackbuilds.org/. It does not have any dependencies. As we do not want yet to replace init with runit, run the slackbuild with CONFIG=no: CONFIG=no ./runit.SlackBuild Then install the resulting package and proceed as follows: mkdir /etc/runit/ /service/ cp -a /usr/doc/runit-*/etc/2 /etc/runit/ /sbin/runsvdir-start & Starting via rc.local For a typical Slackware-stlyle service, you can edit /etc/rc.d/rc.local file if [ -x /sbin/runsvdir-start ]; then /sbin/runsvdir-start & fi and then edit write /etc/rc.d/rc.local_shutdown #!/bin/sh SlackDocs - https://docs.slackware.com/ Last update: 2020/05/06 08:08 (UTC) howtos:slackware_admin:runit https://docs.slackware.com/howtos:slackware_admin:runit RUNIT=x$( /sbin/pidof runsvdir ) if [ "$RUNIT" != x ]; then kill $RUNIT fi Then give rc.local_shutdown executive permission: chmod +x /etc/rc.d/rc.local_shutdown and reboot Starting via inittab (supervised) Remove the entries in /etc/rc.d/rc.local and /etc/rc.d/rc.local_shutdown described above. -

Unit V Algorithm for Booting the UNIX System
Unit V Algorithm for booting the UNIX system : As we’ve noted, the boot process begins when the instructions stored in the computer’s permanent, nonvolatile memory (referred to colloquially as the BIOS, ROM,NVRAM, and so on) are executed. This storage location for the initial boot instructions is generically referred to as firmware (in contrast to “software,” but reflecting the fact that the instructions constitute a program[2]). These instructions are executed automatically when the power is turned on or the system is reset, although the exact sequence of events may vary according to the values of stored parameters.[3] The firmware instructions may also begin executing in response to a command entered on the system console (as we’ll see in a bit). However they are initiated, these instructions are used to locate and start up the system’s boot program , which in turn starts the Unix operating system. The boot program is stored in a standard location on a bootable device. For a normal boot from disk, for example, the boot program might be located in block 0 of the root disk or, less commonly, in a special partition on the root disk. In the same way, the boot program may be the second file on a bootable tape or in a designated location on a remote file server in the case of a network boot of a diskless workstation. There is usually more than one bootable device on a system. The firmware program may include logic for selecting the device to boot from, often in the form of a list of potential devices to examine. -

Um die einleitende Frage zu beantworten, erkläre ich in diesem Kapitel zuerst einige wichtige Begriffe, die im gesamten Buch immer wieder verwendet werden: Betriebs- system, Unix, Distribution, Kernel etc. Ein knapper Überblick über die Merkmale von Linux und die verfügbaren Programme macht deutlich, wie weit die Anwendungs- möglichkeiten von Linux reichen. Es folgt ein kurzer Ausflug in die Geschichte von Linux: Sie erfahren, wie Linux entstanden ist und auf welchen Komponenten es basiert. Von zentraler Bedeutung ist dabei natürlich die General Public License (kurz GPL), die angibt, unter welchen Bedingungen Linux weitergegeben werden darf. Erst die GPL macht Linux zu einem freien System, wobei »frei« mehr heißt als einfach »kostenlos«. 1.1 Einführung Linux ist ein Unix-ähnliches Betriebssystem. Der wichtigste Unterschied gegenüber historischen Unix-Systemen besteht darin, dass Linux zusammen mit dem vollstän- digen Quellcode frei kopiert werden darf. Ein Betriebssystem ist ein Bündel von Programmen, mit denen die grundlegend- Betriebssystem sten Funktionen eines Rechners realisiert werden: die Schnittstelle zwischen Mensch und Maschine (also konkret: die Verwaltung von Tastatur, Bildschirm etc.) und die Verwaltung der Systemressourcen (CPU-Zeit, Speicher etc.).
