1 Setting Up SAMBA Samba is the brainchild of Andrew Tridgell who currently heads the Samba development team from his home of Canberra, Australia. The project was born in 1991 when Andrew created a fileserver program for his local network that supported an odd DEC protocol from Digital Pathworks. Although he didn't know it at the time, that protocol later turned out to be SMB. A few years later, he expanded upon his custom-made SMB server and began distributing it as a product on the Internet under the name SMB Server. However, Andrew could not keep that name it already belonged to another company's product so he tried the following Unix renaming approach: grep -i 's.*m.*b' /usr/dict/words And the response was: salmonberry samba sawtimber scramble Thus, the name Samba was born. Those above-average sys admins have traditionally sneaked Linux into company networks with a file and print server. The software behind this, that allows Linux and most other Unix variants participate seamlessly and even outperform Windows-based machines on small networks, is called Samba. Samba (from the Server Message Block protocol or SMB) is a suite of programs that implement the SMB protocol on Linux. The SMB protocol is the foundation of Windows networking, or as Microsoft now calls it, the Common Internet File System (CIFS). Today, the Samba suite revolves around a pair of Unix daemons that provide shared resources, called shares, to SMB clients on a network. (Shares are sometimes called services as well.) These daemons are: smbd A daemon that allows file and printer sharing on an SMB network and provides authentication and authorization for SMB clients nmbd A daemon that looks after the Windows Internet Name Service (WINS) and assists with browsing SHARANAM SHAH (DOT) COM

2 Page 2 Samba is currently maintained and extended by a group of volunteers under the active supervision of Andrew Tridgell. Like Linux, Samba is considered Open Source software (OSS) by its authors, and is distributed under the GNU General Public License (GPL). Since its inception, development of Samba has been sponsored in part by the Australian National University, where Andrew Tridgell earned his Ph.D. In addition, some development has been sponsored by independent vendors such as Whistle and SGI. It is a true testament to Samba that both commercial and non-commercial entities are prepared to spend money to support an Open Source effort. The latest version of Samba includes many new features to increase compatibility with NT domains and improve performance. Setting up the Linux server as a File and Print server that can be used by Win 9x users on a LAN.! Share one or more filesystems! Share printers installed on both the server and its clients! Assist clients with Network Neighborhood browsing! Authenticate clients logging onto a Windows domain! Provide or assist with WINS name server resolution To achieve some of the above edit the file smb.conf found in /etc/samba. (Refer to diagram 1.1) Start by making a backup of the smb.conf file. <System Prompt> cd /etc/samba <System Prompt> cp smb.conf smb.conf.backup Edit the file /etc/samba/smb.conf. <System Prompt> kate /etc/samba/smb.conf (Refer to diagram 1.1) SETTING UP SAMBA

3 Page 3 Set The Workgroup Or Domain Diagram 1.1: Starting Samba Configuration Change the setting workgroup from MYGROUP to whatever name that's been assigned to the current workgroup or domain. For example, set it to SCTHOME. (Refer to diagram 1.2) Set The Server Description Diagram 1.2: Samba Configuration Change the server string from Samba Server to whatever description that must be broadcast as the server's description. It can be set to SCT Server Orchid (Refer to diagram 1.2) Enable Blank Passwords To enable blank passwords add the following line in the [global] section: null passwords = yes (Refer to diagram 1.3) SHARANAM SHAH (DOT) COM

4 Page 4 Diagram 1.3: Samba Configuration Share CDROM Make the CD-ROM drive on the Server available for public access. Add the following lines to the bottom of the file: (Refer to diagram 1.3) [cdrom] comment = Shared CD ROM Drive path = /mnt/cdrom public = yes only guest = no writable = no printable = no Share Data Added shares at the end of the file: (Refer to diagram 1.3) [downloads] path = /mnt/downloads SETTING UP SAMBA

5 Page 5 public = yes writable = yes browseable = yes [sctdata] path = /mnt/sctdata public = yes writable = yes browseable = yes For writable = yes the location shared needs to be writable in Linux as well. This can be done using chmod command as: <System Prompt> chmod 777 /mnt/downloads <System Prompt> chmod 777 /mnt/sctdata Auto Start Samba Service Use chkconfig to enable samba (smb) in both Runlevels 3 and 5. Runlevels 3 and 5 mean the text interface and graphical interface respectively. (Refer to diagram 1.4) <System Prompt> chkconfig --list smb This lists the current configuration of samba. At all levels samba auto start is off. (Refer to diagram 1.4) <System Prompt> chkconfig --level 35 smb on This switches auto start of samba service to on only in run levels 3 and 5. (Refer to diagram 1.4) <System Prompt> chkconfig --list smb This lists the changes configuration of samba after the above command was issued. The samba service is switched to on in run levels 3 and 5. SHARANAM SHAH (DOT) COM

6 Page 6 Diagram 1.4: Auto Starting Samba From now on the samba service will auto start each time the machine is restarted. Add Users To Samba Add users who can access these shares using the smbpasswd command. Refer to diagram 1.5 <System Prompt> smbpasswd -a <username> Diagram 1.5: Adding the user sharanam Restarting Samba To Apply Changes Restart the SMB services with the command: (Refer to diagram 1.6) <System Prompt> service smb restart SETTING UP SAMBA

7 Page 7 Testing Samba Via A Windows Box Diagram 1.6: Restarting smb service 1. Open Windows Explorer and browse through My Network Place # Scthome # Orchid 2. Click Orchid A user name will be prompted. Key in the username as sharanam. This user was created earlier (Refer to diagram 1.5).

8 Page 8 Do not enter a password as while creating this user no password was entered. This is allowed as null passwords = yes was set while setting up samba. 3. Click OK 4. This will bring up all the shared folders and CDROM available on the server. (Refer to diagram 1.8) Diagram 1.8: The shared folders and CDROM under the Server Orchid This completes configuration and Testing of Samba Server. SETTING UP SAMBA
