| − | ==OVERVIEW==
| |
| − | | |
| − | According to the samba.org website:
| |
| − | | |
| − | ''"Samba is the standard Windows interoperability suite of programs for Linux and Unix. Samba is Free Software licensed under the GNU General Public License, the Samba project is a member of the Software Freedom Conservancy."''
| |
| − | | |
| − | Although a Samba server can provide many features such as printer sharing and backups, this lab's primary focus is to set up a Samba server on a Linux server in order to allow MS Windows users to share common files from the Linux's Samba server.
| |
| − | | |
| − | This lab will first install, setup, and enable a Samba server. Then another virtual machine will be created for a Windows operating system. Finally, within the Windows virtual machine, users will access files from the Linux Samba server (both graphically and command line).

| − | ==INVESTIGATION 1: INSTALLING & CONFIGURING A SAMBA SERVER==
| |
| − | | |
| − | In this investigation, we will set up a '''Samba server''' on our '''VM2''' machine. We will first install, configure and enable the samba server on our virtual machine, and then we will quickly test to see if the Samba server works.

| |
| − | | |
| − | #Make certain that both your '''VM1''' and '''VM2''' machines are running.

| |
| − | #Issue the following Linux command to install Samba server utlity:<br>'''yum install samba samba-client'''<br>
| |
| − | #Move the file '''/etc/samba/smb.conf''' to another filename by issuing the following command:<br>'''mv /etc/samba/smb.conf /etc/samba.smb.conf.original'''
| |
| − | #Create a <u>new</u> '''smb.conf''' file that contains the following lines: | |
| − | [global]
| |
| − | workgroup = WORKGROUP
| |
| − | server string = "put your real name here without the quotes"

| − | Although you can use smbclient to access, browse and share files within other Linux and Windows servers, it is more practical to setup a Samba server to allow MS Windows Users to access a common file share on a Linux machine, and will be demonstrated in Investigation 2.

| |
| − | | |
| − | This investigation will configure your VM2 machine to act as a Samba File server to allow Windows OS Users access to the Linux Samba server files.
| |
| − | | |
| − | === Creating a Windows7 Professional VM ===
| |
| − | | |
| − | To demonstrate how to access and share files from a remote MS Windows server using '''smbclient''' on your '''host''' machine, we will install a Windows7 Professional machine as a virtual machine.
| |
| − | | |
| − | '''Perform the following steps:'''
| |
| − | | |
| − | #Make certain you are using your '''host''' machine.
| |
| − | #Download a version of MS Windows7 Professional ISO file to your host machine. If you have already downloaded an ISO file, then you can use that (i.e. transfer to your host machine).<br>'''NOTE:''' You cannot use a CD/DVD since KVM does not install by CD/DVD.<br><br>'''ALTERNATIVE METHOD:''' You could also refer to the following link to download Windows7 OS image: https://inside.senecacollege.ca/its/software/ , <br>select '''Software Downloads''', login with your senecaid and password, select '''MSDN''', and then select a Windows7 Professional iso image to download.<br>You are <u>not</u> required to obtain a product key since you will not need to extend the use of this Windows OS over 60 days.

| − | {{Admon/tip |Rearming the Windows Trial Version|If are your trial period for your Windows machine is nearly over, you can extend the trial period for another 30 days by running a command prompt as the <u>administrator</u> (right-click on '''cmd''' icon) and issuing the command: '''slmgr -rearm'''. Obviously, you are required to perform this operation prior to the termination of the initial trial period.}}

| − | ===Accessing Files on a Linux Samba Server via Windows Explorer ===
| |
| − | | |
| − | With some additional "tweaking" to your Linux Samba server configuration file, you should be able to access files on that file from a Windows machine on the same network. You will be creating a Samba share for your home directory of your regular user account.
| |
| − | | |
| − | '''Perform the following tasks:'''
| |
| − | | |
| − | # Make certain that both your '''VM2''' and '''Windows''' virtual machines are running.
| |
| − | # On your Windows VM, temporarily turn off the firewall for your Windows machine.
| |
| − | # Open the Windows Explorer application.
| |
| − | # At the top of the application, enter the following:<br>'''\\IPADDR_OF_VM2_MACHINE\home'''
| |
| − | # You will be prompted to enter your VM2 username and password (refer to diagram on right).<br><br>'''NOTE:''' It may take approximately 30 seconds to display the file contents.<br><br>
| |
| − | # Where your successful? If not, try to troubleshoot the problem first, then ask your lab assistant or instructor for assistance.
| |
| − | # Close the Windows Explorer application window.
| |
| − | # Use the control panel to create a '''mapped network drive''' (called it drive '''Z:''' which is a Samba share of your VM2 machine).
