5 1 Introduction FOG cloning solution is a new product of IPBRICK International and it demonstrates, once again, our commitment in providing the technical solutions that will cater to all your needs. FOG is a Linux-based, free and open source computer imaging solution. FOG doesn t use any boot disks, or CDs; everything is done via TFTP and PXE. Also, with fog many drivers are built into the kernel, so you don t really need to worry about drivers. Fog is centralized and enables your system s administrator to clone machines and remotely replicate them to any other at your convenience. This is very useful since it saves you the time, money and effort of manually installing each machine. 2 Product Information With FOG, the end user no longer needs to worry about NIC drivers to image a computer, this is all handled by the kernel. FOG management is done via an easy to use web GUI. FOG is centralized. Most of tasks done on FOG don t require the user to visit the client PC. For example if you imaging a computer all you need to do is start the task. After the task is started the computer will turn on, if it is off, PXE will load the OS, DHCP will give it an IP address, FOG will tell the server it is in progress, and PartImage will image your computer. Then when imaging is done FOG will tell PXE not to boot the machine to the fog image and your computer boots up. After the computer is booted, if the FOG service is installed, FOG will change the computer s hostname and that computer is ready to use! FOG is easy to access. All you need is a web browser to image a computer, no client software required. FOG is Powerful. With features like virus scanning, memory testing, disk wiping, testdisk, and file recovery, FOG does more than just imaging. 5

6 Figure 1: FOG Overview 3 Requirements To install the FOG solution in your IPBRICK you will need: An IPBrick v5.3 with update 11 installed Two FOG software packages (fogpackages_1.0.deb and fog4ipbrick_1.0.deb) 4 Installation Again, we point the fact that to install the two FOG.deb packages you need to update your IPBRICK v5.3 with at least update 11! 4.1 Software The FOG packages is available at our eshop: At: Downloads -> Software -> IPBrick Related Software -> IPBrick 5.3 Note: You have to be registered at our eshop for the Download section to be available. 4.2 Installation Procedure 1. Access IPBrick s web interface: Advanced Configurations > IPBrick > Update (Figure 2); 6

7 Figure 2: IPBrick Update page Install them in this order: (a) fogpackages_1.0.deb (b) fog4ipbrick_1.0.deb. 2. Click on the Browse button, select the fogpackages_1.0.deb and install it; 3. Please follow the installation instructions; 4. Repeat the procedure for fog4ipbrick_1.0.deb 5. Apply Configurations. If the package was correctly installed you will be able to visualize that indication on the Update page of IPBRICK s web interface. Note: Please don t forget to Apply Configurations!!! 5 Important Technical Notes FOG is a simple solution but it requires that you follow these notes, in order for it to function properly: All machines (the ones subject of cloning and also the ones that are going to be replicated have to be registered in IPBRICK. This is done via IPBRICK s web interface at: IPBRICK.I > Machines Management No disk can be partitioned! The file system used in those disks can only be an ext1, ext2 or ext3 all other versions of ext or other file systems are not compatible. 7

8 Cloning must always happen between disks of the same capacity or from a smaller to a larger one. In this last case, the exceeding capacity will not be read, i.e: A disk with 80GB cloned from a 40GB disk will have an excess of 40GB, but this memory will be useless, for all purposes when cloning from a smaller to a larger disk, the latter will become of the same capacity as the smaller one. We strongly advise you to clone machines with the same hardware specifications. Problems may arise from cloning machines with different motherboards, CPUs, etc. 6 FOG s Graphical User Interface (GUI) After installation you will may access the FOG s web interface via web browser, the URL is: Note: Please substitute domain.com with your own domain name. You will be asked to login. Figure 3: FOG Login page These are the default credentials: Username: fog Password: password After login you will have a main index page. 8

9 Figure 4: FOG s GUI index page Before operating with FOG s GUI In order to clone a machine to one or several hosts you will need to configure the clone machine BIOS to boot by network. The following sections will guide you through the process of creating a clone image from a machine 7 and also to replicate that same image to one or several hosts 8. 7 Creating an image file 1. Access the BIOS of the machine that is going to be cloned (remember that it has to be registered at IPBRICK) and at Boot options change the configuration in order that it will boot first from the network. Figure 5: BIOS Boot Options 2. Access the FOG s GUI and click on the Image Management icon; 9

10 Figure 6: Image Management icon 3. Click on the New Image link; 4. Give it a Name, Description, default storage group, filename, and Image type (Select: Single Disk (Not Resizable)). 5. Click on the Add button. Figure 7: Image Management page Note: All this does is to create a label at the IPBRICK server, this will serve to identify the image you will create. The actual image is not yet stored! 6. The next step is to create Hosts (machines) here at the FOG s GUI. As stated previously all these hosts have to be inserted at IPBRICK; 7. Click on the Host Management icon; 10

11 Figure 8: Host Management icon 8. Click now on the Add New Host link. On the Host insertion form fill the first three fields (Host Name, Host IP and Primary MAC) exactly the same as in IPBRICK; Figure 9: Host Management page Select the image you created (e.g.:ubuntu12_04) and its OS. Click on Add to create the host. When you have inserted the host a confirmation will appear at the top of the page. Figure 10: Inserted Host Confirmation 11

12 9. Access the Host Management page - List All Hosts again you can see the Pinging process and the host name, click on it. Figure 11: Host Management page with a Host You will access the Host s data form but on the left side of the screen you will find several links, click on Basic Tasks; Figure 12: Host Management - Host s form 10. At the new Basic Tasks page choose Upload; 12

13 Figure 13: Basic Tasks At the new prompt simply click on the Upload Image button; Figure 14: Upload Image 11. After the image is successfully stored you will have to revert the cloned machine s BIOS boot option, from Network, back to the original option (CD/DVD drive, USB Pen, etc.) 8 Assign Image to Host 1. In order to assign the Image to another host or several other hosts (remember that they have to be registered at IPBRICK), you will have to repeat the insertion process at Host Management and also repeat the BIOS option process of configuring the host(s) BIOS boot options to start first from the 13

14 network (you will have to do this in every machine that will host the new image you have stored). Figure 15: BIOS Boot Options 2. Access the FOG s GUI and click on Host management. 3. This will list all hosts. Select the host(s) you wish to clone with the image you created. Figure 16: All Hosts 4. Click on Host Image, select the image that you created in the previous step. 14

15 Figure 17: Host Management Selecting the image 5. At the new Basic Tasks page choose Deploy; Figure 18: Basic Tasks 6. Confirm by clicking on the Image All Computers button 15

16 Figure 19: Confirm Task 7. After the host is updated you will have to revert their BIOS boot option from Network back to the original option (CD/DVD drive, USB Pen, etc.) 8. Finally, you will need to change the machine s name: Windows: Right click on My Computer and select Properties; Figure 20: My Computer - Properties Click on Computer Name tab and rename the computer by clicking on the Change button; 16

17 Figure 21: Computer Name At the new window change the computer name. Figure 22: Computer Rename Ubuntu: Open a Konsole and log in as a super user (sudo su) 17

18 Figure 23: sudo su Edit the file: vi /etc/hosts Figure 24: Open the etc-hosts file with the vi editor Change the host name in the hosts file; Figure 25: Edit the machine s name in the Hosts file Also edit the vi /etc/hostname file; Figure 26: Open the hostname file with the vi editor Edit the name. 18
