1 15. Creating a Samba Server in Knoppix v.3 Estimated Time: 60 minutes Objective In this lab, the student will start the samba service in Knoppix, allowing transfer of files to and from a indows XP computer on the network. Equipment The following equipment is required for this exercise: A computer with Knoppix 3.9 running. A computer on the same network with Windows XP running. Scenario The users of the company s workstations need to share files between Linux or Knoppix computers and Windows computers. The easiest way to do this is with a samba connection. Procedures In the first steps of this lab, the student, as root will create a user account and will also enable that user as a samba user with a samba password. Root will then turn on the samba service. The student will create a user account on the Windows computer and create a shared folder and a test file for viewing. The student will, from the Knoppix computer, view the contents of the Windows shared folder. The student will copy the test file to the Knoppix computer. After file transfer in this direction is verified, the student will view the Knoppix user s folder from Windows Explorer. A test file from the Knoppix computer will be copied onto the Windows computer. Preliminary step for Knoppix users First, click the Knoppix Penguin icon, to get to the root shell. Assign yourself a root password with the passwd command, and enter the password twice. passwd Changing password for user root. Enter new UNIX password: Retype new UNIX password: The password will be successfully updated. If you do not currently have a user account, create one now, based on your name. For example, Maria Chavez could create a user account like this: useradd m s /bin/bash mchavez As root, assign your new account a password in this way. For Maria s case, she would type (while logged in as root): passwd mchavez Changing password for user mchavez. Enter new UNIX password: Retype new UNIX password: Type it twice and it will be accepted. In Knoppix, passwords are locked by default. That is why mchavez couldn t create her own password immediately after her user account was created. Root has to do it. Step 1: Configure the network connection Login with the root account for the first part of this lab. Use the root shell, which should already be open, as the terminal window. Type netcardconfig

2 This GUI application will guide the student through the process of setting up the IP address for the NIC. If there are questions about the proper addresses to use, ask the instructor. Step 2: Add a samba user Type smbpasswd a mchavez New SMB password: net@ccess1 Retype new SMB password: net@ccess1 NOTE: The password must be complex for SMB to accept it: 8 characters long and a mix of uppercase, lowercase, numbers, and symbols. This command adds the user mchavez as a samba user by placing an entry in the file /etc/samba/smbpasswd. It also assigns the samba password net@ccess1 to that user. Notice that root can do this without the samba server being started. The user mchavez had to exist on the system (with an entry in /etc/passwd) before mchavez can be added as a samba user. Put a test file in the home directory of mchavez. It will be viewed later from the Windows computer. Type touch /home/mchavez/file2 Step 3: Start the Samba server Still as root, type /etc/init.d/samba start Starting Samba daemons: nmbd smbd is the output. The samba server is now running. Step 4: Prepare the Windows XP computer for the Samba connection -- Add User 1. On the Windows XP computer, use Control Panel to add a user and password that matches the samba user you created on the Knoppix machine (mchavez and net@ccess1 respectively). 2. At the Windows computer, log in with the name of the samba user with which you want to connect. Step 5: Prepare the Windows XP computer for the Samba connection -- Create Share 1. On the Windows XP computer, turn off 'Simple File Sharing': Go to 'My Computer' and double click on 'Local Disk C'. Then select 'Folder Options' under the 'Tools' menu. 2. Under 'Folder Options' find the 'View' tab. Go the bottom of the list under 'Advanced Settings' and clear the check box next to 'Use simple file sharing (Recommended)' then click 'OK' 3. In Explorer window on the C: drive, go to File -> New -> Folder and name the new folder share 4. Right click on the folder and select 'Sharing and Security' 5. Select the 'Security' tab and click on 'Add'

3 6. Type 'Everyone' in the box titled 'Enter the object names to select' and click on 'OK' 8. Select the 'Sharing' tab, select 'Share this folder' and type in the name 'share' then click on OK

4 9. The 'share' folder will appear with a hand beneath to indicate that the computer has shared the folder with the network. Verify that the share is available by either typing 'net view \\machinename' in a command window or clicking 'Start' -> Run and typing \\machinename. Replace 'machinename' with either the IP address or the Computer name of the machine you are working on. 10. Using Notepad, add a file named file1.txt in the 'share' folder. Type at least one line of text into this file. (for example, your name and school: Fred Flintstone Bedrock High School ) 11. Verify the share: Click on Start*Run and type '\\ \share' The next window should show the file1.txt

5 Step 6: Mount the remote computer in the Knoppix file system Login as root. Type cd /mnt mkdir samba-conn This creates a directory where the remote Windows computer will appear. In the following example, the Windows computer has the name windows-machine. In the screenshot, the Windows computer was called HP-xp Type mount t smbfs //windows-machine/share /mnt/samba-conn Step 7: Verify the samba connection from the Knoppix side The shared folder on the Windows computer should be visible under the mount point. Type cd /mnt/samba-conn ls The contents of the shared folder on the Windows computer should appear in the output. You should see the file called file1. Copy the test file to your local home directory. Type cp file1 /home/mchavez Verify that you can view the local copy s contents. Type cd /home/mchavez more file1 Do you see the text that you originally created in the file file1 in the Windows computer? The following image shows typical output. The Windows computer name was HP-xp. In this example, the test file was called file1.txt. Step 8: Verify the samba connection from the Windows side At the Windows computer, log in with the name and password of the samba user that you created in Step 4 above. Using My Network Places, navigate to Entire Network, Microsoft Windows Network, Workgroup.

6 Under Workgroup, a computer called Knoppix should appear. Under that computer, the home folder of the samba user should appear, mchavez for the example in this lab. Do you see the test file, file2 that you created on the Knoppix computer in Step 2? You should be able to drag a copy of it to another folder on the Windows computer. Now you have a samba server running on your network. You can transfer files between it and any Windows machine that can connect to it.
