5.b : Installing various software packages - Advanced Samba, CUPS, Django. Aim: To know the how to install the packages like Samba, Common Unix Printing System (CUPS) and Django.
1. Samba Installation and Configuration 1.1 Introduction to Samba Samba can be used with Linux to provide transparent access between machines running Linux and machines running Windows. Samba itself runs on a Linux machine and makes shared files and printers available to Windows machines, as if they are available on a Window machine or server. Thus, Samba has several practical applications which can generally be categorized as follows: 1. Using a Linux server as a simple peer-to-peer server. There is no user authentication involved and no need for passwords. 2. Using a Linux server as a member server on an existing Windows NT domain. The existing Windows domain controller will use NT authentication tools to control file permissions and access. 3. Using a Linux server as a primary domain controller with its own user authentication and control mechanisms. Which of these three applications of Samba is used, determines how Samba is configured on the Linux machine.
1.2 Installing Samba $ su Enter Password: (Here enter the root password) # yum install samba Checking the samba running. # /etc/init.d/smb status

Configuring samba Creating a normal user # useradd samba-test Setting the password # passwd samba-test Changing password for user samba-test. New password: Retype new password: passwd: all authentication tokens updated successfully. Adding the user to access samba shares with a password # smbpasswd -a samba-test New SMB password: Retype new SMB password: Added user samba-test. Login into the samba as using the smbclient to add the files and folders to share with windows. # smbclient \\\\localhost\\samba-test -Usamba-test Here enter smb password for login Enter samba-test's password: You gets the following output to see the what are files you are sharing Domain=[MYGROUP] OS=[Unix] Server=[Samba 3.5.8-68.fc15] smb: \> In this to see what are files you sharing enter ‘ls’ command smb: \> ls .

How to access the shared files from windows. Open the samba location as following. Start-> Run.. Enter the ip address of linux machine as following eg: \\192.168.1.2
It displays log in window to log into the samba sever. Here username and password should be what you given to while creating samba username and smb password. eg:
username: samba-test password:test123
Now you can see the what are files shared.

2. Common Unix Printing System (CUPS) Printing within UNIX has historically been done using one of two printing systems - the Berkeley Line Printer Daemon ("LPD") [RFC1179] and the AT&T Line Printer system. These printing systems were designed in the 70's for printing text to line printers; vendors have since added varying levels of support for other types of printers.
Linux Printing features ● All printing systems on Linux make use of the excellent PostScript system called GhostScript (www.ghostscript.org). ● Ghostscript is a PostScript interpreter that is most commonly used on Linux. ● Implements an excellent PostScript engine that can take as inputs formats like JPEG, TIFF, PS & Text and output data in formats like X Windows output, raster formats and PDF. ● Also handles conversion of PS output for non-PS printers; can also be used a basic, spooler less printing system. ● Most printing systems today use a combination of multiple tools (postscript interpreters, filters, rasterises etc) to process and print documents. ● The printing system converts PostScript into a raster format and then converts that into a printer specific language to send commands to the printer.
Installing CUPS To Install CUPS Enter the Following command as root user $ su # yum install cups Install the A printer administration tool # yum install system-config-printer
Configuring CUPS Open the cups by typing following URL http://localhost:631/

Then CUPS search for the printers available in your network.
If your printer is connected to the network it shows in the Discovered Network Printers. Select the printer and click on Continue button.

3. DJANGO 3.1 Introduction to DJANGO Django is an web application framework, written in Python, which follows the ModelView-Controller (MVC) Pattern. It is named after Django Reinhardt, a gypsy jazz guitarist from the 1930s to early 1950s. To this day, he’s considered one of the best guitarists of all time. Django is pronounced JANG-oh. Rhymes with FANG-oh. It was originally developed to manage several news-oriented sites for The World Company of Lawrence, Kansas, etc., and was released publicly under BSD license by July 2005. In June 2008, It was announced that a newly formed Django Software Foundation will take care of Django in the future.
3.2 Installing DJANGO Installation First, download Django-x.x.tar.gz from the following link http://FOSS-LAB-SERVER-IP/content/code/Django/Django-x.x.x.tar.gz Go to Applications -> System Tools -> Terminal and type the follwing commands $su Enter Password: (Here enter the root user password) # tar xzvf Django-x.x.tar.gz # cd Django-x.x #python setup.py install
