=Samba - A Windows SMB/CIFS fileserver for UNIX=
{{Admon/important|Warning| Make sure that your VMs are fully updated before you begin this lab. }}
 
==Configuring a Samba Server on Linux==
*On your host F16 system VM 2 install Samba yum 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 = OPS335 <yourlearnid>.org
server string = "put your real name here without the quotes"
encrypt passwords = yes
smb passwd file = /etc/samba/smbpasswd
hosts allow = 142.204.141. ; note: the above line will allow access from the Seneca domain in lab T2107
[home]
comment = "put your real name here without the quotes"
path = /home/<learnid>
valid users = <learnid>
; remember <learnid> is your learnid account name
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
*You can change a user's password by using the command smbpasswd <learnid/username>*Test and review your configuration with the command
testparm
*You can now start your Samba server systemctl start (smb.service*Ensure your server starts ) and ensure it will start at boot. *You will need to determine which ports you need to open Modify the firewall on VM2 to allow connections to your serversamba traffic.
*Test if you have a connection with the command
smbclient -U <learnid> -L f16vm2*If the previous command worked, try the connection from one It will show you a list of your VM's. You can view all available shares with the follow command: smbtree -N.
=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 vm01 the host use the "smbclient" command in a terminal window. smbclient '\\f16vm2\home' -U <learnid>
*After entering your password you should get a prompt similar to
smb: \>
smb: \> ls
NT_STATUS_ACCESS_DENIED listing \*
*SE Linux should be in Enforcing and will need to be adjusted (on the samba server) for this to work. Check the available booleans or your logs. setsebool -P samba_enable_home_dirs 1*Use Once you have access to the directory use the get and put commands (similar to ftp) to move files.*When done enter you are finished close the quit commandconnection. == Using 'mount -t cifs ' ==
*The next way is to use the mount command.
*Use the mount command on vm01 the host to mount your home directory mkdir /tmp/f16vm2-home mount -t cifs //f16vm2/home /tmp/f16vm2-home -o username=<learnid>#*If the previous step worked, browse your ls /tmp/mnt directory using cd and ls commands and when done use the umount command to unmount your Matrix vm2-home directory.#The first way is == Using Nautilus to use browse Samba shares ==*Use the "Places" menu from a Gnome the desktop:and open 'Browse Network'.#*As rootFrom the menu in the side-bar of the files tool, ensure Samba is installedchoose 'Connect to Server'. Use these two commands: "yum install samba" and "yum install samba-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 Enter 'smb:/etc/sambavm2/smb.conf file home' as the location, and immediately after enter your samba password in the [global] section header insert these two lines:prompt.#**client plaintext auth = yes#**client lanman auth = yes#*Create a new account on Fedora with Where vm2 is the same name as your LEARN acount. Set of the password to 'seneca99'.#*Logout of joker server, and login to Fedora using your LEARN home is the nameof the directory it is sharing.#*Now try the following:#*From the "Places" menu at the top of After you have checked that you can access your screenfiles, select "Network" and wait until unmount the network scan completes. Then click on share by right-clicking its icon in the "Windows Network" side-bar and then click the "File" menu and select "Connect to Server", change the service type to "Windows Share" and input matrix.senecac.on.ca for the server, your username for the ShareName and UserName fields. Then click the Connect buttonclicking 'Unmount'.  == Using a browser ==*You should now be able to browse your Matrix files.#The second way is to 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 Location edit box address bar enter the following: ' smb://matrixvm2/xxxxxx'. Where xxxxxx is home*Enter your Matrix usernameand password when prompted. #*Login to your Matrix account. Konqueror should open Double click on a window of your Matrix home directoryfile you have some text in. #*Use the mouse to drag *Open it with gedit, make some changes, and drop files save it.**When prompted, choose to and from your Matrix account and your Fedora Linux machineupload the file.*Close Konqueror.*cat the file on your VM2 to ensure the changes were properly uploaded.
===Connecting to a Linux SMB Server (Matrix) 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 prerouting and forwarding rules to your desktop. Double-click it Centos host's iptables necessary to login redirect samba traffic from outside your network to your Matrix accountVM 2.*Open up Explorer and Right click on Computer > Map network drive.. A window > Select a Drive Letter and '\\<ip-address-of -host>\home' > you will then be asked for your Matrix home directory should openusername and password.*Use the mouse You should now be able to browser, drag and drop your files to and from your Matrix account and your the Windows 7 lab machine.*Once you are satisfied that ==Completing the Lab==While completing this lab you can easily move files have gained experience using a service designed to/allow interaction from your Matrix account power off the PCa variety of client tools on multiple OS platforms.*Set the HD selector switch You have also experienced service related tools that allow you to boot from your Fedora 13 Linux drive view configuration parameters and power on the PCerrors in real-time.
==Completing the Lab==Answer the following Exploration questions#What is your full name and 9 digit Seneca student ID?#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.:
#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 was did the exact mount setsebool command that you used in the last step of the labdo?
