Double-click it to login to your Matrix account. A window of your Matrix home directory should open.*Use the mouse to drag and drop files to and from your Matrix account and {{Admon/important|Warning| Make sure that your Windows 7 lab machine.*Once you VMs are satisfied that fully updated before you can easily move files to/from your Matrix account power off the PCbegin this lab.}}*Set the HD selector switch to boot from your Fedora 13 Linux drive and power on the PC.===Connecting to Configuring a Linux SMB Samba Server (Matrix) from a on Linux Client (Fedora 13)===There are 4 ways that a Linux client can connect to an SMB server. Start by logging into *On your Fedora 13 system as joker and opening a terminal window.#The first way is to use the "Places" menu from a Gnome desktop:VM 2 install Samba#*Switch to root and ensure you are using the default Fedora 13 firewall.#*As root, ensure Samba is installed. Use these two commands: "yum dnf 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 Create a backup of the file /etc/samba/smb.conf file , and immediately after create a new one that includes only the following: [global] section header insert these two lines:#**client plaintext auth workgroup = <yourlearnid>.org server string = "put your real name here without the quotes" encrypt passwords = yes#**client lanman auth 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*Create Now add a new account on Fedora with parameter to the global section that will limit access to the same name as share so that only machines in your LEARN acount. Set virtual network and those in the password lab room will be able to 'seneca99'access it.#*Logout of joker and login Add a parameter to Fedora using the home section so that only your LEARN nameuser account can access that share.#*Now try Create a Samba password for user <learnid> with the following:command smbpasswd -a <learnid>#*From the "Places" menu at the top of your screenIf you need to, select "Network" and wait until you can change a user's password by using the network scan completes. Then click on command smbpasswd <username>*Confirm the "Windows Network" and then click user you created has been added using the "File" menu following command pdbedit -L -v*Test and select "Connect to Server" and input matrix.senecac.on.ca for the server, review your username for configuration with the ShareName and UserName fields. Then click the Connect button. command testparm*You should can now be able to browse start your Matrix filesSamba server (smb.service) and ensure it will start at boot.#The second way is *Modify the firewall on VM2 to use a web browser with support for the SMB protocol such as Konquerorallow samba traffic. #*If Konqueror is not installed then install it Test if you have a connection with the command: 'yum install kdebase'. # smbclient -U <learnid> -L vm2*Start Konqueror, the web/file browser, and in the Location edit box enter the following: 'smb://matrix/xxxxxx'It will show you a list of all available shares. Where xxxxxx is your Matrix username =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 ==*Login In a full installation you should not need to install samba-client on your Matrix account.

'''THIS PART WILL PROBABLY NOT WORK !'''#*Use the mount command on the host 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.#** mkdir /tmp/vm2-home mount -t cifs //matrixvm2/home /xxxxxx tmp/mnt vm2-home -o username=xxxxxx<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'. *where xxxxxx is Enter 'smb://vm2/home' as the location, and enter your your Matrix usernamesamba password in the prompt.#*If *Where vm2 is the name of the previous step workedserver, browse your /mnt directory using cd and ls commands and when done use home is the name of the umount command to directory it is sharing.*After you have checked that you can access your files, unmount your Matrix home directorythe share by right-clicking its icon in the side-bar and clicking 'Unmount'.

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?
