Kari-Pekka Kauhanen ETÄYHTEYDET Opinnäytetyö Kajaanin ammattikorkeakoulu Luonnontieteiden ala Tietojenkäsittely 1.3.2011 OPINNÄYTETYÖ TIIVISTELMÄ Koulutusala Koulutusohjelma Luonnontieteiden ala Tietojenkäsittely Tekijä(t) Kari-Pekka Kauhanen Työn nimi Etäyhteydet Vaihtoehtoisetvaihtoehtiset ammattiopinnot Ohjaaja(t) Tarja Karjalainen Toimeksiantaja Aika Sivumäärä ja liitteet 1.3.2011 43 Opinnäytet yön tavoitteena on perehtyä etäyhteyden teoriaan ja tutkia teorian pohjalta erilaisia etäyhteysohjelmis- toja. Tutkimuksen tarkoituksena on ottaa selvää etäyhteysohjelmistojen tietoturvaominaisuuksista ja kuinka pal- jon eri etäyhteysohjelmistot rasittavat tietokoneen resursseja. Tuloksien perusteella valitaan yhteensopivin etäyh- teysohjelmisto organisaatiokäyttöön. Opinnäytetyö käsittää teoriaosan, jossa kerrotaan erilaiset etäyhteysprotokollat. Etäyhteysprotokollista kerrotaan tärkeimmät ominaisuudet ja protokollan toimintaperiaate. Etäyhteysprotokolliin kuuluu esimerkiksi VNC, RDP, X11 ja PcoIP –protokollat. Protokollan tarkka teoriatuntemus auttaa selvittämään eri käyttötarkoituksiin parhai- ten sopivan protokollan. Opinnäytetyö käsittää tutkimusosion, joka tarkastelee VNC- ja RDP-protokollia käyttäviä etäyhteysohjelmistoja, koska VNC- ja RDP-protokolla ovat käytetyimmät etäyhteysprotokollat. Tutkimus käsittää ohjelmistojen asen- nuksen, yhteyden muodostuksen ja käytettävien tietokoneen resurssien mittauksen. Asennusvaiheessa etäyhteysohjelmisto asennetaan yhteyden muodostusta varten. Yhteyden muodostuksessa tut- kitaan miten yhteys muodostetaan -
Collabkit – a Multi-User Multicast Collaboration System Based on VNC
Humboldt-Universität zu Berlin Institut für Informatik Lehrstuhl für Rechnerorganisation und Kommunikation Diplomarbeit CollabKit – A Multi-User Multicast Collaboration System based on VNC Christian Beier 19. April 2011 Gutachter Prof. Dr. Miroslaw Malek Prof. Dr. Jens-Peter Redlich Betreuer Peter Ibach <[email protected]> Abstract Computer-supported real-time collaboration systems offer functionality to let two or more users work together at the same time, allowing them to jointly create, modify and exchange electronic documents, use applications, and share information location-independently and in real-time. For these reasons, such collaboration systems are often used in professional and academic contexts by teams of knowledge workers located in different places. But also when used as computer-supported learning environments – electronic classrooms – these systems prove useful by offering interactive multi-media teaching possibilities and allowing for location-independent collaborative learning. Commonly, computer-supported real-time collaboration systems are realised using remote desktop technology or are implemented as web applications. However, none of the examined existing commercial and academic solutions were found to support concurrent multi-user interaction in an application-independent manner. When used in low-throughput shared-medium computer networks such as WLANs or cellular networks, most of the investigated systems furthermore do not scale well with an increasing number of users, making them unsuitable for multi-user collaboration of a high number of participants in such environments. For these reasons this work focuses on the design of a collaboration system that supports concurrent multi-user interaction with standard desktop applications and is able to serve a high number of users on low-throughput shared-medium computer networks by making use of multicast data transmission. -

CLOUD-X Remote Desktops and Applications Through Web Browsers
CLOUD-X Remote Desktops and Applications through Web Browsers Edgar Fabi´an Hern´andez-Ventura and Jorge Buenabad-Ch´avez Departamento de Computaci´on, CINVESTAV-IPN, Ciudad de M´exico, D.F., Mexico Keywords: Remote desktops, Web browsers, Cloud computing. Abstract: Cloud computing is gaining general acceptance and we believe it will broaden its user base significantly once users can run their favourite applications in the Cloud through web browsers and with the same interface that each such application is used in a desktop or laptop computer. This paper presents CloudX, a new architecture based on web browser techonologies for the X Window system. X Window is the de facto standard for window display in Unix-like operating systems. CloudX translates X Window commands to web browser display commands using AJAX and SVG (Scalar Vector Graphics) technologies. CloudX does not require any extension to the X Window system nor any plugin to the web browser. 1 INTRODUCTION based architecture for the X Window system.

Virtual Network Computing
Virtual Network Computing In computing, Virtual Network Computing (VNC) is a graphical desktop sharing system that uses the RFB protocol to remotely control another computer. It transmits the keyboard and mouse events from one computer to another, relaying the graphical screen updates back in the other direction, over a network. VNC is platform-independent – a VNC viewer on one operating system may connect to a VNC server on the same or any other operating system. There are clients and servers for many GUI- based operating systems and for Java. Multiple clients may connect to a VNC server at the same time. Popular uses for this technology include remote technical support and accessing files on one's work computer from one's home computer, or vice versa. VNC was originally developed at the Olivetti Research Laboratory in Cambridge, United Kingdom. The original VNC source code and many modern derivatives are open source under the GNU General Public License. VNC in KDE. There are a number of variants of VNC[1] which offer their own particular functionality; e.g., some optimised for Microsoft Windows, or offering file transfer (not part of VNC proper), etc. Many are compatible (without their added features) with VNC proper in the sense that a viewer of one flavour can connect with a server of another; others are based on VNC code but not compatible with standard VNC. VNC and RFB are registered trademarks of RealVNC Ltd. in the U.S. and in other countries. Etymology The name 'Virtual Network Computer/Computing' originates from ORL's work on a thin client called the Videotile which also used the RFB protocol.
