==SAMBA=====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, the Linux penguin, on your desktop. DoubleSamba -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 your Windows 7 lab machine.*Once you are satisfied that you can easily move files toSMB/from your Matrix account power off the PC.*Set the HD selector switch to boot from your Fedora 13 Linux drive and power on the PC.===Connecting to a Linux SMB Server (Matrix) from a Linux Client (Fedora 13)==CIFS fileserver for UNIX=There are 4 ways {{Admon/important|Warning| Make sure that a Linux client can connect to an SMB server. Start by logging into your Fedora 13 system as joker and opening a terminal window.#The first way is to use the "Places" menu from a Gnome desktop:#*Switch to root and ensure VMs are fully updated before 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-client"#*Fedora encrypts passwords when authenticating SMB connections. Unfortunately Windows clients (here at Seneca) insist on passwords being sent in plain text. For begin 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 '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 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 button. 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 WILL PROBABLY 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=xxxxxx#***where 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 directorylab.}}

===Configuring an SMB a Samba Server on Linux===*On your host F16 system VM 2 install Samba yum dnf install sambasamba-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.
