10. For each possible action you have to create later on a wInst script setup This script is executed for the installation of the product It consists normally of an operating system disk space check and of course the required installation commands Additionally it s possible to include an image or icon uninstall This script is executed for the uninstallation of the product It solely consists of uninstallation commands update This script allows executing the update routine of software always The commands in this script are executed on each system start Can be useful for inventory software but in general it is used rarely once This script is just executed once After that it is set to off or not_installed This script type is highly rarely used and should be ignored gt custom 21 This script type doesn t affect the installation status After execution OPSI doesn t detect any changes This script type is highly rarely used and should be ignored user login This feature is not yet implemented The last step is to plan the dependencies and properties of a product Does the product have No Yes which ones product id dependencies Does the product have special No l Yes which ones properties The properties are then important when a product has multiple installation possibili ties versions or other adjustments These options can vary from client to cli

Import the minimal OPSI products The OPSI products consist of installation procedures for Operating Systems and more There is a tool called opsi product update which automatically downloads all necessary packages from the OPSI repository Opsi product update installs the packages after wards on the server This is the command to execute the update process rootadepotserver opsi product updater i vv Finally it is advisable to check for updates and upgrade the server in the end root depotserver apt get update root depotserver apt get upgrade 40 5 7 1 OPSI Backup Like every other rather complex system also OPSI should be backed up from time to time since OPSI is an important centralized tool for Windows Client and Windows Server Management There are many methods to backup up OPSI The usual method takes use of the integrated opsi backup command Basically OPSI consists of 4 core elements Although those core elements can vary on each system depending on their configuration OPSI Configuration This is the most important element since it holds the configuration All configuration files are stored in this location etc opsi This is the core element regarding of data storage All clients products configuration etc are saved in the corresponding data backend The available backends are file backend mysql backend ldap univention and dhcp All information is stored in the etc opsi backendMa

It is possible to downsize the client administration remarkably The tasks are not solved locally anymore Everything is centralised controlled by few people Furthermore OPSI doesn t know boundaries therefore it will even work in a WAN There is no version conflict of applications or patches since the client environment is unified by the de potserver Based on the thesis work and its result OPSI has also disadvantages even though it is free of charge As a matter of fact the expenses of hardware equipment acquisition can be extremely high Furthermore it usually takes some time to familiarize with the OPSI documentation and preparation and installation of the depotsever as well as the actual client rollout Therefore it is recommendable to provide OPSI instruction courses for system administrators Additionally for each single application used in the company you have to create a package Packetizing of each single application is rather time con suming However despite of all this I can recommend OPSI to every small or middle sized company The limit of simultaneously clients in OPSI 4 0 1 is somewhere around a few thousands Therefore I wouldn t recommend big companies with more than 5000 employees clients to use OPSI since they are not able to administrate all clients and hence unable to take advantage of OPSI 59 OPSI in the basic form may be used by anyone as it is Being free and customisable offers a competitive advantage over comm

76. rts in my thesis my starting point is set exactly there I will not consider the pre work like the installa tion of Ubuntu nor Windows 2003 Server in my documentation although it is calculat ed in the time schedule However I will emphasise on the subject OPSI and its fea tures The initial point is set to a working environment This includes both necessary servers Ubuntu and Windows 2003 as well as the test clients Windows clients The initial point of the Ubuntu server is a clean installation with all necessary updates The initial point of the Windows 2003 server is a clean installation with all necessary up dates and efficient DNS service as domain controller and likewise the windows client just without DNS service running All machines are on the same network and properly connected and working Thereby the goal is now to install OPSI and its features on the Ubuntu server and test the functions thoroughly and moreover document the process 4 2 Study Methods During my research I am going to invest quite a lot of time reading the official OPSI manual and the OPSI getting started guide The background idea is to get more theory experience of OPSI Especially the official OPSI manual provides detailed knowledge to master OPSI and all its features whereas the OPSI getting started guide deals with the first steps of OPSI and tackles mainly the installation part Com bined the manual and the guide are excellent reference mater
