INTRODUCTION

InthistutorialIwilldemonstratehowtoinstallaVNCserviceonyourLattePandausingWindows.Thiswillenableyouto

accesstheGUIofWindowsrunningonyourLattePandafromadifferentPConyourlocalnetwork.IwilluseTightVNC,a

freeandeasytosetupservice.

VNCstandsfor“VirtualNetworkComputing”.Itisawayoftransmittingthekeyboardandmouseeventsofonecomputer

toanother-inotherwordsusingonecomputertoremotecontrolanother.Thisisusefulbecauseyoumightnothaveextra

monitors,keyboardsormicelyingaround–usingaVNCserviceenablesyoutoaccessseveralcomputersonyourlocal

networkusingjustonecomputer,monitor,keyboardandmouse.Youmightalsohaveaheadlessserversetupwhich

doesn’trequireconstantlyattachedperipherals.SettingupaVNCserveronyourheadlessserverisahandywayto

interfacewithaGUIifandwhenyouneedit.

Let’sgetstarted:

STEP 1 - INSTALLATION
