This change will create an SMB share named sharedoc consisting of the contents of the directory /usr/share/doc and below. 11.3.4 Adding a Samba user The default method that Samba uses to determines users’ credentials is to look in the /etc/samba/smbpasswd file. That user must first exist in the Linux file system (/etc/passwd, /etc/shadow, etc). Perform the following steps ► To create a new Samba user, the smbpasswd -a command is used. First use the useradd and passwd commands to add a user locally. In this example, the user sambauser1 is used: # id sambauser1 id: sambauser1: No such user # useradd sambauser1 # passwd sambauser1 Changing password for sambauser1. New password: lnx4vm BAD PASSWORD: it is based on a dictionary word BAD PASSWORD: is too simple Retype new password: lnx4vm passwd: all authentication tokens updated successfully. ► Add the user sambauser1 to the smbpasswd file with the smbpasswd -a command: # smbpasswd -a sambauser1 New SMB password: lnx4vm Retype new SMB password: lnx4vm startsmbfilepwent_internal: file /etc/samba/smbpasswd did not exist. File successfully created. account_policy_get: tdb_fetch_uint32 failed for field 1 (min passwd length), returning 0 ... Added user sambauser1. This method of maintaining Samba users, groups and passwords is good for a small number of users. For a larger number of users, merging Samba and LDAP is recommended. It is not a simple as pointing the virtual file and print server at the virtual LDAP server as described in “Creating a virtual LDAP server” on page 173 because the Samba schema must first be added to LDAP. Details are outside the scope of this book. 11.3.5 Starting Samba at boot time Samba can be started for the current session with the service command and at boot time with the chkconfig command. Do this for both the smb and nmb services: # service smb start Starting SMB services: [ OK ] # service nmb start Starting NMB services: [ OK ] # chkconfig smb on # chkconfig nmb on Samba should now be running and configured to start at boot time. 11.3.6 Testing your changes You can verify that Samba is running with the following service command: 180 The Virtualization Cookbook for RHEL 6
# service smb status smbd (pid 6987 6982) is running... You can verify the shares that are available with the following smbclient command: # smbclient -U sambauser1 -L localhost Domain=[MYGROUP] OS=[Unix] Server=[Samba 3.5.4-68.el6] Sharename Type Comment --------- ---- ------sharedoc Disk RHEL 6 on System z documentation IPC$ IPC IPC Service (Samba Server Version 3.5.4-68.el6) sambauser1 Disk Home Directories Domain=[MYGROUP] OS=[Unix] Server=[Samba 3.5.4-68.el6] ... Server Comment --------- ------- GPOK226 Samba Server Version 3.5.4-68.el6 Workgroup Master --------- ------- MYGROUP GPOK226 You can test getting a Samba share from a Windows desktop. Perform the following steps ► Go to any Windows Explorer window (such as My Computer) and select Tools -> Map Network Drive. ► Use the Universal Naming Convention (UNC) to specify the Samba server and share name as shown in the upper left corner of Figure 11-2 on page 182. In this example the UNC is \\9.60.18.226\sharedoc. ► You may have to click different user name if the user or password on the new Samba server is different from the Windows system you are connecting from. ► Click Finish. If all the steps were correct, you should see the files in a new Explorer window as shown in the bottom right corner of Figure 11-2 on page 182. Chapter 11. Cloning open source virtual servers 181
