Samba Basic Hands-On Practice 3

Scenario:

The Tropics travel agency has expanded significantly and now has 30 full 
time employees and a part time administrator. There is now concern about 
the employees modifying each other's files. Each travel agent will have a 
username and password assigned to them. The part time administrator 
"Mr. Master" will be able to access and modify any of the other travel 
agents' documents. 

For our purposes, assign each agent a password that is the same as the 
username and we will only create 5 of the 30 agent accounts. We will use 
the following usernames: mrmaster, agent01, agent02, ... agent05. Each 
agent will have their own share. Mr. Master will be able to access other 
agent's files through a "master" share that only he can access.

In the past, travel agents used their own printers on their home 
computers. Now the office has installed a high capacity printer that
is to be shared by everyone.



Steps
1. Verify that cups is installed. If it isn't installed you will need to 
   install it via the "Add/Remove Applications" application. If cups is 
   installed, the following command will print out the version number of 
   cups that is installed on the system.

rpm -qa | grep cups


2. Add a group account for the agents to use.

groupadd agents


3. Install the new configuration for the company. Backup the
   current configuration. Download the configuration and move it into
   place.

cd /etc/samba
rm smb.conf
wget joelandrebecca.martintribe.org/linuxconf/samba/smb.conf.example3
cp smb.conf.example3 smb.conf


4. Edit your smb.conf to make sure to set your netbios name to
   a unique name so that you won't collide with other students.


5. Create the UNIX account for Mr. Master and set his password to 
   "mrmaster". Don't worry if it complains about your password. As
   root you can do anything. Add the user to the Samba password file
   with the exact same password.

useradd -m -G agents -c "Mr. Master" mrmaster
passwd mrmaster
smbpasswd -a mrmaster


6. Create the UNIX accounts for the travel agents. Repeat the 
   following for all 5 agents. Make sure to set the UNIX and Samba
   account passwords to exacltly the same thing.

useradd -m -G agents -c "Agent 1" agent01
passwd agent01
smbpasswd -a agent01


7. Create the directory structure for the file shares. Don't worry
   if you don't understand the command. Trust me.

for i in mrmaster agent01 agent02 agent03 agent04 agent05; do 
  mkdir -p /data/$i
  chown $i /data/$i
done
chgrp -R agents /data
chmod -R ug+rwxs,o-r+x /data


8. Your instructor will provide a command to configure the correct
   CUPS printer queues for your use. The command will look something
   like this:

lpadmin -p PRINTQ -v parallel:/dev/lp0 -E


9.  Edit the file /etc/cups/mime.convs to uncomment the line:

application/octet-stream     application/vnd.cups-raw      0     -


10.  Edit the file /etc/cups/mime.types to uncomment the line:

application/octet-stream



Verification

5. Validate the syntax of the configuration file

testparm


6. Restart Samba services (smbd and nmbd) and cups services and setup 
   samba and cups so that they restarts everytime the machine is booted:

chkconfig smb on
chkconfig cups on
/etc/init.d/smb restart
/etc/init.d/cups restart


7. Verify that the shares are visible from the server side

smbclient -L localhost -N
smbclient -L NETBIOS_NAME -N


8. Ensure that all Windows clients are in the same network (same
   netmask i.e. 255.255.255.0), and set workgroup names of all Windows
   clients to the same as specified in the smb.conf configuration
   file. 


9. Login as mrmaster. Verify that mrmaster has full access to the 
   "master" share and all agent directories under it.


10. Logout and log back in as one of the agent accounts. Verify that
    the agent has full access to the "files" share, but cannot access
    the "master" share at all.


11. Install a printer driver and test printer sharing using the 
    following steps:

   1.  Click Start->Settings->Printers+Add Printer+Next. Do not click 
       Network printer. Ensure that Local printer is selected.
   2.  Click Next. Select the correct Manufacturer and Printer. 
       Click Next.
   3.  In the panel labeled Available ports:, select FILE:. Accept the 
       default printer name by clicking Next. When asked, “Would you like 
       to print a test page?”, click No. Click Finish.
   4.  You may be prompted for the name of a file to print to. If so, 
       close the dialog panel. Right-click PRINTER NAME->Properties.
   5.  In the panel labeled Network, enter the name of the print queue 
       on the Samba server as follows: \\SERVER\PRINTQ. Click OK+OK to 
       complete the installation.
   6. Create a test page in Wordpad and try and print it to the printer.
   7. If the page doesn't print to the print, check to see if the 
      job is queued on the Samba server within the cups system by
      running the following command:

lpq
