En Linux-Guide För Serveradministratörer En Linux-guide för serveradministratörer Niklas Antin FörnamnExamensarb Efternamn ete Informations- och medieteknik 2014 EXAMENSARBETE Arcada Utbildningsprogram: Informations- och medieteknik Identifikationsnummer: 4537 Författare: Niklas Antin Arbetets namn: En Linux-guide för serveradministratörer Handledare (Arcada): Jonny Karlsson Uppdragsgivare: Jonny Karlsson Sammandrag: Examensarbetes syfte och målsättning är att utveckla svenskspråkigt stödmaterial för studerande i Arcada samt minska tröskeln för att komma igång med operativsystemet Linux. I den första delen av arbetet presenteras filstrukturen samt filers accessrättighet- er. Grunderna i användning av kommandotolken samt programmering av skript beskrivs ingående. Den andra delen handlar om de vanligaste tjänster och programvara som oftast installe- ras på en Linux server. Dessa tjänster är fildelning, programvara för underhåll av ser- vern och webbservertjänster. Arbetet fokuserar sig på att gå igenom installering och konfigurering av dessa tjänster i detalj med hänsyn till att studerande som använder detta stödmaterial är nybörjare i Linux. Materialet i examensarbetet är baserat på litteraturstudier om Linux samt praktiskt in- stallering och konfigurering av tjänster och programvara. De praktiska exempel som presenteras i arbetet är alla gjorda i Ubuntu, som är ett av de populäraste Linux- distributionerna. De praktiska exemplena betonar även datasäkerhetsaspekter. Målet är att materialet i framtiden skall publiceras på en Wiki-sida som kan uppdateras efter- hand, som sedan kommer att göras tillgänglig för både studenter och lärare vid Arcada. Nyckelord: Linux, Administrator, Ubuntu, Filstruktur, Rättigheter, Bash-skript, Apache, SSL, SSH, Samba, MediaWiki, FTP Sidantal: 53 Språk: Svenska Datum för godkännande: DEGREE THESIS Arcada Degree Programme: Information and Media Technology Identification number: 4537 Author: Niklas Antin Title: Linux-guide for server administrator Supervisor (Arcada): Jonny Karlsson Commissioned by: Jonny Karlsson Abstract: The purpose of the thesis work is to provide Swedish support material for students in Ar- cada and also reduce the threshold for making one familiar with the Linux operation sys- tem. In the first part of my work I will present the Linux file structure and user rights and also the basics of the command prompt and script programming. The second part deals with the most common services and software one most often in- stalls in a Linux server. These services are file sharing, maintenance software for the server and web server services. The thesis focues on going through the installation and configuration processes in detail with that in mind that the students who might be using this support material are not so aware about all the different functions in the Linux opera- tion system. The information in this thesis is based on literature study about Linux and on practise to install and configure different services and programs. The practical examples presented in this thesis are all made with Ubuntu which is the most common distribution of Linux. In these practical examples I have paid attention to security aspects also. The goal is that the support material will be published on a Wiki page, available to both students and teachers in Arcada, which can be updated when needed.

This means that in theory, you should be able to use ReactOS just like a Windows system: install the same drivers, run the same software, etc. However, in practice, the implementation is not complete enough to allow you to do this. You can run the simple tools that come with the OS, but not much else. Wine offers a much better chance of being able to run Windows software without a full Windows install.

  • What Is a DAW? What Is a DAW?
    2021/07/26 16:00 (UTC) 1/2 What is a DAW? What is a DAW? In simple terms, a Digital Audio Workstation is a device where you create and manipulate digital audio. Before the era of personal computing, a DAW would be a complex piece of (expensive) hardware which was only within reach of music studios or artists of name and fame. A good example of an early DAW is the Fairlight CMI (Computer Musical Instrument), released in the late 70’s of the previous century. This Fairlight was also one of the first to offer a digital sampler. The picture at the left of this page is its monitor with a light-pen input. These days, the name “DAW” is often used for the actual software used to produce music, like the free Ardour, LMMS, or the commercial Ableton Live, FL Studio, Cubase, Pro Tools, etcetera. But “Digital Audio Workstation” also applies to the computer on which this software is running and whose software and hardware is tailored to the task of creating music. To make it easier for musicians who use Linux, you can find a number of custom distributions with a focus on making electronic music, such as StudioWare (Slackware based), AV Linux (Debian based), QStudio64 (Mint based), so that you do not have to spend a lot of time configuring your Operating System and toolkits. Overview of DAW related content Page Description Tags Slackware Live DAW: Compensating Latency Overview of Slackware Live Latency and its Sources Audio data is moved in “chunks”, howtos, DAW: called buffers, which contain a number of audio samples.
