How to Install samba In Ubuntu Server

        1 sudo apt-get install samba

Change samba configuration file

/etc/samba$ sudo vim smb.conf

[global]

       ; use the name of your Samba server instead of [server name] (sv001)

       ; and your own workgroup instead of [Domain name] VTC

        netbios name = sv001

        workgroup = VTC

        encrypt passwords = yes

        server string =

       

       domain master = yes

        local master = yes

        preferred master = yes

        os level = 65

        security = user

        domain logons = yes

        ; logon path tells Samba where to put Windows NT/2000/XP roaming profiles

        logon path = \\%L\profiles\%u

        logon script = %g\logon.bat

        logon drive = H:

        ; logon home is used to specify home directory and

        ; Windows 95/98/Me roaming profiles location

        ; logon home = \\%L\%u\.win_profile\%m

       

        time server = yes

        ; the below works on Red Hat Linux – other OSs might need a different command

        add user script = /usr/sbin/useradd –d /dev/null –g users –s /bin/false –m %u

       

[netlogon]

        path = /usr/local/samba/lib/netlogon

        writable = no

        browsable = no

       

[profiles]

        ; you might wish to use a different directory for your

        ; Windows NT/2000/XP roaming profiles

        path = /home/samba-ntprof

        browsable = no

        writable = yes

        create mask = 0600

        directory mask = 0700

[homes]

        read only = no

        browsable = no

        guest ok = no

        map archive = yes

[transfer]

       path = /home/transfer

       browsable = yes

       guest ok = no

       writable = yes

       create mask = 0644

       directory mask = 0755

[office-docs]

      path = /home/office-docs

      browsable = yes

      guest ok = no

      writable = yes

      create mask = 0660

      directory mask = 0770

        force group = office

Command Checker Samba Configuration:  

testparm

Create 3 Groups (students, teachers, office)

        sudo groupadd students

        sudo groupadd teachers

        sudo groupadd office

Creating Directory on the Samba Server

The [netlogon] and [profiles] shares defined in our new smb.conf file reference directories on the Samba Server, and it is necessary to create those directories with the proper permissions:

        # mkdir – p /usr/local/samba/lib/netlogon (-p create sub folders Like mkdir /usr/local/treat/tyer/)

        # chmod 775 /usr/local/samba/lib/netlogon

        # mkdir /home/samba-ntprof

        # chmod 777 /home/samba-ntprof

        # mkdir /home/transfer

        # chmod 755 /home/transfer

        # mkdir /home/office-docs

Change the group owner (office-docs)

       # chgrp office /home/office-docs

       # chmod 770 /home/office-docs

Restart the Samba Daemon

        # /etc/init.d/samba restart

Create folders 3 in /usr/local/samba/lib/netlogon: (teachers, students, office)

Create logon file in the each folder above:

       # /usr/local/samba/lib/netlogon$ (teachers, students, office)

       sudo vim logon.bat

In folder teachers

        net time \\sv001 /set /yes

        net use /delete T:

        net use T: \\sv001\transfer

        net use /delete O:

        net use O: \\sv001\office-docs

Before Save or Close type command :se ff=dos

In folder office

        net time \\sv001 /set /yes

        net use /delete T:

        net use T: \\sv001\transfer

        net use /delete O:

        net use O: \\sv001\office-docs

Before Save or Close type command :se ff=dos

In folder students

        net time \\sv001 /set /yes

        net use /delete T:

        net use T: \\sv001\transfer

Before Save or Close type command :se ff=dos

Change Samba root password

        sudo smbpasswd -a root

Synchronize time

        sudo ntpdate swisstime.ethz.ch
Create script file backuppasswdfiles.sh (/home/vtc)

#!/bin/sh
rm –f passwd
cp /etc/passwd .
rm –f shadow
cp /etc/shadow .
rm –f group
cp /etc/group .
rm –f smbpasswd
cp /etc/samba/smbpasswd .

Create script file createsmbuser.sh in vtc user (/home/vtc)

#!/bin/sh
# (-s /bin/false we don't allow user to logon to server)
useradd –s /bin/false –g $2 –G $3 –m $1
# (R: recursive)
chmod -R 700 /home/$1
# (force: don't show warnings)
# (.??* we remove any file with 3 or more letters)
rm –Rf /home/$1/.??*
# (-a: add smbuser)
smbpasswd –a $1
# (-p: protoname or template)
edquota –p test.user $1
# backup password files automatically
./backuppasswdfiles.sh

Assign execution rights to script

        chmod 700 backuppasswdfiles.sh

   chmod 700 createsmbuser.sh

Copy Default User

        sudo cp –R Default\ User/ /usr/local/samba/lib/netlogon

Create the new users and then

        sudo ./createsmbuser.sh <username> <maingroup> <additional groups>

        eg. # sudo ./createsmbuser.sh test.user office users,internet

Samba Users

 Assign the Computer for Client to login to the Domain Server

        sudo useradd –s /bin/false –d /dev/null –g users [computer name$]

Install Quota

        use quota documentation (Install Quota Share Limit Space.doc)

Join Windows Computer to Domain

Create addgroup.sh and delgroup.sh script

1.    cd

2.    vim addgroup.sh
#!/bin/sh

groupnr=`awk -F: '{if ($1 == groupstr) print $3}' groupstr=$2 < /etc/group`

userlist=`awk -F: '{if ($4 == groupnr) print $1}' groupnr=$groupnr < /etc/passwd`

for user in $userlist

do

              adduser $user $1

done

./backuppasswdfiles.sh

3.    vim delgroup.sh

#!/bin/sh

groupnr=`awk -F: '{if ($1 == groupstr) print $3}' groupstr=$2 < /etc/group`

userlist=`awk -F: '{if ($4 == groupnr) print $1}' groupnr=$groupnr < /etc/passwd`

for user in $userlist

do

              deluser $user $1

done

./backuppasswdfiles.sh

4.    chmod +x addgroup.sh delgroup.sh

5.    sudo ./addgroup.sh <add this group> <to members in this maingroup>

sudo ./addgroup.sh internet teachers

6.    sudo ./delgroup.sh <remove this group> <from members in this maingroup>

sudo ./delgroup.sh internet teachers

NOTE:

        id <username> (Show group and membership)

        smbstatus (Samba Status)

Delete user and password

        sudo userdel –r <username>

        sudo vim /etc/samba/smbpasswd to delete user & password

        sudo rm –r /home/samba-ntprof/user profile

Install a printer share through logon.bat
