=Samba - A Windows SMB/CIFS fileserver for UNIX={{Admon/important|Warning| Make sure that your VMs are fully updated before you begin this lab. }} ==SAMBAConfiguring a Samba Server on Linux==*On your VM 2 install Samba dnf install samba samba-client*Create a backup of the file /etc/samba/smb.conf, and create a new one that includes only the following: [global] workgroup =<yourlearnid>.org server string ="put your real name here without the quotes" encrypt passwords = yes smb passwd file = /etc/samba/smbpasswd [home] comment = "put your real name here without the quotes" path = /home/<learnid> public = no writable = yes printable = no create mask = 0765*Now add a parameter to the global section that will limit access to the share so that only machines in your virtual network and those in the lab room will be able to access it.*Add a parameter to the home section so that only your user account can access that share.*Create a Samba password for user <learnid> with the command smbpasswd -a <learnid>*If you need to, you can change a user's password by using the command smbpasswd <username>*Confirm the user you created has been added using the following command pdbedit -L -v*Test and review your configuration with the command testparm*You can now start your Samba server (smb.service) and ensure it will start at boot. *Modify the firewall on VM2 to allow samba traffic.*Test if you have a connection with the command smbclient -U <learnid> -L vm2*It will show you a list of all available shares. =Connecting to a Linux SMB Server from a Linux Client=There are many ways that a Linux client can connect to an SMB server. == Using smbclient ==*In a full installation you should not need to install samba-client on your host, but if it is not present then do so.*You will also need to install the cifs-utils package to be able to mount the filesystem.*From the host use the "smbclient" command in a terminal window. smbclient '\\vm2\home' -U <learnid>*After entering your password you should get a prompt similar to smb: \>*Enter the ls command to see a list of the files in your home directory - you may receive the following error. smb: \> ls NT_STATUS_ACCESS_DENIED listing \**SE Linux should be in Enforcing and will need to be adjusted (Matrixon the samba server) for this to work. setsebool -P samba_enable_home_dirs 1*Once you have access to the directory use the get and put commands (similar to ftp) to move files.*When you are finished close the connection. == Using 'mount -t cifs' ==*The next way is to use the mount command.*Use the mount command on the host to mount your home directory mkdir /tmp/vm2-home mount -t cifs //vm2/home /tmp/vm2-home -o username=<learnid> ls /tmp/vm2-home == Using Nautilus to browse Samba shares ==*Use the "Places" menu from the desktop and open 'Browse Network'.*From the menu in the side-bar of the files tool, choose 'Connect to Server'. *Enter 'smb://vm2/home' as the location, and enter your samba password in the prompt.**Where vm2 is the name of the server, and home is the name of the directory it is sharing.*After you have checked that you can access your files, unmount the share by right-clicking its icon in the side-bar and clicking 'Unmount'. == Using a browser ==*You can also use a web browser with support for the SMB protocol such as Konqueror.**Note that firefox does not have such support. *If Konqueror is not installed then install it with the command: yum install kdebase*Start Konqueror, the web/file browser, and in the address bar enter the following smb://vm2/home*Enter your username and password when prompted.*Double click on a file you have some text in.**Open it with gedit, make some changes, and save it.**When prompted, choose to upload the file.*Close Konqueror.*cat the file on your VM2 to ensure the changes were properly uploaded. =Connecting to a Linux SMB Server from a Windows Client (Windows 7)===
*Power up a Windows 7 system in the lab and login using your LEARN username and password.
*You should see an icon of Tux, Add the Linux penguin, on your desktop. Double-click it to login prerouting and forwarding rules to your Matrix account. A window of your Matrix home directory should open.*Use the mouse Centos host's iptables necessary to drag and drop files to and redirect samba traffic from outside your Matrix account and your Windows 7 lab machine.*Once you are satisfied that you can easily move files network to/from your Matrix account power off the PCVM 2.*Set the HD selector switch to boot from your Fedora 13 Linux drive Open up Explorer and power Right click on the PCComputer > Map network drive.===Connecting to a Linux SMB Server (Matrix) from a Linux Client (Fedora 13)===There are 4 ways that a Linux client can connect to an SMB server. Start by logging into your Fedora 13 system as joker and opening > Select a terminal window.#The first way is to use the "Places" menu from a Gnome desktop:#*Switch to root Drive Letter and ensure you are using the default Fedora 13 firewall.#*As root, ensure Samba is installed. Use these two commands: "yum install samba" and "yum install samba'\\<ip-address-of-client"#*Fedora encrypts passwords when authenticating SMB connections. Unfortunately Windows clients (here at Seneca) insist on passwords being sent in plain text. For this reason Matrix SMB is set to use plain text passwords. To change Fedora to use plain text passwords switch to root and edit the /etc/samba/smb.conf file and immediately after the [global] section header insert these two lines:#**client plaintext auth = yes#**client lanman auth = yes#*Create a new account on Fedora with the same name as your LEARN acount. Set the password to host>\home'seneca99'.#*Logout of joker and login to Fedora using your LEARN name.#*Now try the following:#*From the "Places" menu at the top of your screen, select "Network" and wait until the network scan completes. Then click on the "Windows Network" and > you will then click the "File" menu and select "Connect to Server" and input matrix.senecac.on.ca be asked for the server, your username for the ShareName and UserName fields. Then click the Connect buttonpassword. *You should now be able to browse your Matrix files.#The second way is to use a web browser with support for the SMB protocol such as Konqueror. #*If Konqueror is not installed then install it with the command: 'yum install kdebase'. #*Start Konqueror, the web/file browser, and in the Location edit box enter the following: 'smb://matrix/xxxxxx'. Where xxxxxx is your Matrix username. #*Login to your Matrix account. Konqueror should open a window of your Matrix home directory. #*Use the mouse to drag and drop files to and from your Matrix account and your Fedora Linux machine.Close Konqueror.#The third way is to use the "smbclient" command in a terminal window.#*At the command prompt enter the following:#** smbclient '\\matrix\xxxxxx' -U xxxxxx#***where xxxxxx is your Matrix username#**You should get a prompt similar to#***smb: \>#*Enter the ls command to see a list of your Matrix files.#**Enter ? to see a list of smbclient commands.#**Use the get and put commands (similar to ftp) to move files to and from your Matrix account and your Fedora 13 Linux system.#**When done enter the quit command.#The fourth way is to use the mount command. THIS PART IS IN RED BECAUSE IT PROBABLY WILL NOT WORK !Use the mount command to mount your matrix home directory. NOTE: This mount command will only work if your kernel was configured to allow mounting CIFS with unencrypted passwords. mount -t cifs //matrix/xxxxxx /mnt -o username=xxxxxxwhere xxxxxx is your your Matrix username.If the previous step worked, browse your /mnt directory using cd and ls commands and when done use the umount command to unmount your Matrix home directory.PART C: Configuring an SMB Server on LinuxLogin to Fedora as joker and open a terminal windowWindows machine.Use "su -" to become root.Ensure SAMBA is installed: yum install sambaEdit the file /etc/samba/smb.conf, delete all original lines and include the following: [global] workgroup = OPS335 server string = "put your real name here without Completing the quotes" encrypt passwords Lab= yes smb passwd file = /etc/samba/smbpasswd hosts allow = 142.204.141. ; note: the above line will allow access from the Seneca domain in While completing this lab T2107   [home] comment = "put your real name here without the quotes" path = /home/xxxxxxx valid users = xxxxxxx ; remember xxxxxxx is your LEARN/MATRIX account name public = no writable = yes printable = no create mask = 0765You can comment out all other lines in the file.Create a SAMBA password for user xxxxxxx with the command smbpasswd -a xxxxxxxTest your configuration with the command testparmYou can now start your SAMBA server /etc/init.d/smb start or service smb startTest if you have gained experience using a connection with the command smbclient -L 142.204.141.yyy -Uxxxxxxx%pppppppwhere 142.204.141.yyy is your Fedora Linux IP addressand xxxxxxx is your Matrix account nameand ppppppp is your SAMBA passwordIf the previous command worked, use another PC (Fedora then Windows) service designed to establish allow interaction from a connection with the SMB server variety of client tools on your Fedora Linux machinemultiple OS platforms. This step is important to ensure your SMB server on Linux is working. NOTE: If your set up looks correct but You have also experienced service related tools that allow you can't connect to your SMB server from the outside then you may need to adjust your firewall to allow SMB connections.From another Linux PC, use the mount command to mount your home directory onto /mnt. Step 4 view configuration parameters and errors in PART B should help you with this. Record this command as you'll need it for PART Dreal-time.PART D: Answer the following questions
What is your full name and 9 digit Seneca student ID?In PART C step 9, explain how you connected to your SMB server on Linux from a Windows PC. List exactly what you had to do on the Windows PC to test your Linux server.Exploration questions:#What is the purpose of the testparm command?What is the purpose of the smbclient command?#What does SMB stand for? CIFS?#What does the text inside square brackets in the smb.conf file mean? (e.g., "[homeshome]").#Explain the meaning of the line "create mask = 0765" in the smb.conf file?#What does the smbpasswd command do?#What exact mount did the setsebool command did you use in PART C step 10do?
