This instructor guide

Classroom Setup

The instructor and each student have a physical machine of their own. This physical machine is installed with SLES 11 (da-host). On this installation the VMware Player software is installed to run another SLES 11, called da1, in a virtual machine.

The required hardware consists of a x86 compatible computer with 2 GB RAM and 2 GHz clock speed, DVD drive, and Ethernet network card.

As we cannot provide the VMware Player software you have to download it from http://www.vmware.com (http://www.vmware.com).

The machines are connected to each other using an Ethernet network. Internet access is not vital during the course.


Version 18


da1 provides services the students need for the exercises (such as DNS), and also serves as second machine in some of the exercises that involve two machines.

In the following it is explained how to setup the computer to do the exercises. You have to do the following:

“Set Up da-host” on page 10

“Set Up da1” on page 14

Set Up da-host

da-host is the machine where students work most of the time during the exercises. This machine will host the da1 VMware virtual machine. To install da-host, you can use one of the following methods:

“Install da-host by Using AutoYaST” on page 10

“Install da-host Manually” on page 11

After that, you have to do the following task:

“Install VMware Player” on page 13

Install da-host by Using AutoYaST

On the course CD in the Setup directory, you can find an AutoYaST XML file for the installation of da-host, called da-host.xml. Depending on your host’s hardware, copy the file to another storage device:

Table Intro-2 Copies of da-host.xml

To install da-host using AutoYaST, do the following:

1. Be sure there are no data on the server that you still need, because all existing data on the hard disk will be erased.

2. Boot the server from the SUSE Linux Enterprise Server 11 Product DVD.

3. When the installation screen appears, highlight the Installation option by using the arrow keys.

You have 20 seconds to highlight the option before GRUB boots from the hard drive.

Available Hardware Storage Location for da-host.xml

2 CD/DVD drives No copy needed

Floppy disk drive Copy to floppy disk

USB port Copy to USB stick or USB hard drive

NFS and DHCP server in your network Copy into the exported directory on your NFS server


9Version 1


4. Set the display resolution by pressing F2; then select the display resolution matching your monitor, it should not be less than 1024x768.

5. Insert the media containing the file da-host.xml.

6. In the Boot Options field, type the following (depending on the media containing the da-host.xml file):

da-host.xml on the course DVD:

autoyast=dvd:///Setup/da-host.xml instmode=cd

da-host.xml on a floppy disk:

autoyast=floppy:///da-host.xml instmode=cd

da-host.xml on a USB device:

autoyast=usb:///da-host.xml instmode=cd

da-host.xml on an NFS server:

autoyast=nfs://IP-address/path_to_file/da-host.xml netsetup=dhcp

Then press Enter.

The kernel loads and the SUSE Linux Enterprise Server 11 installation begins.

YaST accesses the file da-host.xml and installs SLES 11 according to the configuration contained in that file.

7. (Conditional) If the installation stops at some early point, reset the computer, restart the installation and try one of the other installation options, like Installation—ACPI Disabled.

Install da-host Manually

To install da-host manually, do the following:

1. Boot your Workstation with the SUSE Linux Enterprise Server 11 DVD.

Wait while the machine boots.

2. When the GRUB installation screen appears, highlight the Installation option by using the arrow keys.

You have 20 seconds to highlight the option before GRUB boots from the hard drive.

2. Login to the graphical desktop as geeko (password: novell).


Version 112

http://www.vmware.com/download/player/

http://www.vmware.com/download/player/


3. Open a terminal and switch to user root by entering su - (password: novell).

4. Install VMware Player by entering

rpm -ihv /path/to/VMware-Player-2.x.x-x.i386.rpm

5. Create the /vmware directory and make it writable for regular users:

mkdir -m 1777 /vmware

6. Unpack the da1-sles11.zip archive:

cd /vmware

unzip /path/to/da1-sles11.zip

chown -R geeko: /vmware/da1-sles11

7. Create the /etc/sysconfig/network/ifcfg-vmnet1 file with the following content:

BOOTPROTO='static'STARTMODE='auto'USERCONTROL='no'IPADDR='172.17.8.1/16'

8. To make sure the settings in the file take effect, reboot your computer.

9. After the reboot, log in as geeko and open a terminal window.

10. In the terminal window, enter ip a s dev vmnet1. You should see an output similar to the following:

da-host:~ # ip a s dev vmnet16: vmnet1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 1000 link/ether 00:50:56:c0:00:01 brd ff:ff:ff:ff:ff:ff inet 192.168.172.1/24 brd 192.168.172.255 scope global vmnet1 inet 172.17.8.1/16 brd 172.17.255.255 scope global vmnet1 inet6 fe80::250:56ff:fec0:1/64 scope link valid_lft forever preferred_lft forever

The other address you see in the output above (192.168.172.1/24) is the address VMware Player assigns to the interface. It is not relevant, as da1 uses a fixed IP address (172.17.8.101/16) and does not rely on IP addresses being distributed by VMware Player via DHCP.

Set Up da1

da1 is a SUSE Linux Enterprise Server 11. This virtual machine provides services, you need for the exercises (like DNS). To set up the machine, do the following:

1. As user Geeko, open the main menu, click More Applications and select System > VMware Player.

2. In the End User License Agreement dialog, click Accept.

3. (Optional) If you are prompted to download available updates, click Cancel.

4. Click Open an existing Virtual Machine.

You should see echo replies.

9. You are now ready to begin with the first exercise.

NOTE: Included on the course DVD is the emptyVM.zip file that contains a VMware image with no operating system installed. It is not used during the course. You could use it, for instance, to install a SLES 11 server or SLED11 desktop and configure it according to your own requirements.

Teaching Tips

The teaching tips include

Student Manual Tips

The following are tips and feedback specific to the student manual from the beta teach of Course 3100:

Section 1: Manage Software for SLE11

No tips for this section at this time.

Section 2: Manage Hardware



Version 114


Section 3: Manage NFS

When exporting a directory using the YaST NFS Server module, a comma is missing in the suggested options for NFSv4. Instead of crossmnt,rw,... it suggests crossmntrw,... You should mention this to the students as the options get written incorrectly to the /etc/exports file and the NFS server fails to start.

Section 4: Configure and Use OpenLDAP


Section 5: Configure and Use Samba


Section 6: Internet Protocol Version 6 (IPv6)

To familiarize yourself with IPv6 we recommend to test 6to4-Tunneling as described in the manual, or to apply for a 6in4-Tunnel with www.sixxs.net or other provider and test that.

Section 7: Deploy SUSE Linux Enterprise 11

The steps to create an Add-on Product repository and the add_on_products.xml file need to be followed exactly for it to work.

Section 8: Manage Virtualization with Xen

It is not possible to change a DVD using virt-manager, one has to use the command line. Otherwise Xen works quite well.

Student Workbook Tips

We did our best to incorporate the feedback from the beta into the final version of the exercises, there is little to add at this point.
