One would think that an easy task. It actually is, once you know how it is done.  And in this article I am going to show you two different ways of making the connection to your Samba server. You will need to have a working knowledge of how the Samba server is set up as well as a username/password configured on the Samba server. There are also a few steps to take on the desktop for one certain method of connection.

The two methods I will describe are: Using GNOME’s Connect To Server dialog and the command line. The latter will be used to show you how to set up auto mounting for Samba.

The graphical method

Figure 1

If you take a look at the GNOME Places menu you will see an entry labeled “Connect to server…”. This is what you want to use in order to connect to your Samba server. When you click on that a new window will open. From the Service type drop-down select “Windows share” (see Figure 1).

When you select that entry some of the configuration options will change. As you can see (in Figure 1), I have entered the necessary options to connect to a Samba server on my internal network. You will want to replace the information so it reflects your needs. The only tricky bit of information might be the Folder entry. If you are connecting to the root directory on the share you will not need to enter anything there. Say, for instance, you share is /media/samba/user. If you want to connect to that directory leave the Folder entry blank. Say, however, you want to connect directly to a sub-folder within that share – you can enter that folder here. This, of course, isn’t needed because you can always traverse the sub-directories with simple navigation. You can also choose to add a bookmark instantly, from in this window.

Figure 2

Once you have all of the information entered click Connect and you will be greeted with a new window that requires you to enter a password. Also, if you do not supply a Domain name in the previous window, you will be required to enter it here.

You can also set this up to remember your password either until you logout or until, well, forever. Once you have entered the password/domain click the Connect button and a new Nautilus window will open inside of your Samba Share.

Using the command line

Now we’re going to use the command line to accomplish a similar goal. The biggest difference is that we are going to actually mount the Samba share into another directory, very much the same way we would mount a second hard drive.

There are a few pieces to put together before we actually take care of the mounting. First let’s create a directory that the Samba share will be mounted to. So from the terminal window issue the following command:

sudo mkdir /media/samba

Now let’s make sure our users can read/write to this directory with the command:

sudo chmod -R u+rw /media/samba

Okay now let’s make sure we can see the Samba shares from the command line. We’ll do that with the smbclient command like so:

smbclient -L //SAMBA_SERVER_ADDRESS

Where SAMBA_SERVER_ADDRESS is the actual IP address of the Samba server.

Figure 3

You will be prompted for your username and password. If you get an error it could be that the usernames don’t match on each end. If that’s the case you could add the -U switch to the command like so:

smbclient –user=jlwallen -L  //SAMBA_SERVER_ADDRESS

You should see output similar to that shown in Figure 3.

Now it’s time to try to mount the Samba share to the /media/samba directory. To do this issue the command:

sudo mount -t cifs //SAMBA_SERVER_ADDRESS/SHARE -o username=USERNAME /media/samba/

Where:

• SAMBA_SERVER_ADDRESS is the IP address of the Samba server.
• SHARE is the share name.
• USERNAME is the username to connect with.

If that works you can now make this an automated mount by adding the following line to your /etc/fstab file:

//SAMBA_SERVER_ADDRESS/SHARE     /media/samba    cifs  credentials=/etc/samba/user.cred 0 0

Where SAMBA_SERVER_ADDRESS is the IP address of the Samba server and SHARE is the share name.

Notice the user.cred file. This is one last thing we need to create. With your text editor create this file and place into it:

username=USER

password=PASSWORD

Where USER is the username to log in with and PASSWORD is the password to use for authentication. The final step is the give this new file the proper permissions with the command:

sudo chmod 600 /etc/samba/user.cred

You can ensure this works by issuing the command mount -a which should mount your Samba share.

Final thoughts

You should now have an auto-mounting Samba share – or the ability to easily connect your GNOME desktop to a Samba share. Samba is a very powerful tool that not only can share files with Windows machines, but with Linux machines as well.

In this article I am going to show you how to get a basic Samba Server up and running on top of that Ubuntu Server. Now, because the Ubuntu Server was set up as a headless server, the installation and configuration of Samba will be done completely from the command line. So get your fingers ready to type.

What is Samba?

Samba is a very handy tool that can do many things. The primary task it serves is to enable a Windows machine to access a Linux machine serving as a file and/or print server. Samba uses the SMB/CIFS protocols to enable communication between the Windows and the Linux machine.

Samba has often been thought of as very difficult to get up and running. It’s not really that bad. Hopefully, by the end of this article, you will have a fairly good understanding of how to get it up and running.

Installing Samba

As I said, you will doing this completely from the command line. The command to issue is:

sudo apt-get install samba

You will have to enter your sudo password to continue with the installation. Depending upon your server installation, you might have to okay some dependencies. Go ahead and do this and then watch as Samba is installed.

Once installed you will have the Samba executable in /etc/init.d/. In order to start Samba you will issue the command:

/etc/init.d/samba start

Of course, before you start Samba, you will need to configure Samba. There are a few steps to take care of. Let’s first deal with the configuration file.

Configuring Samba

Before you get too deep into this you might want to first read my article “Get To Know Linux: Understanding smb.conf“. The Samba configuration file is located in the /etc/samba directory and is called smb.conf. When you first open up this file you may be overwhelmed. Let’s avoid that by making a backup of the original smb.conf file. Change to the /etc/samba directory with the command:

cd /etc/samba

Now issue the following command:

sudo cp smb.con smb.conf.bak

Now you can open up the smb.conf file and erase the entirety of its contents. How do you do that? If you are using the Nano editor it’s simple. With the file open hold the Ctrl key and the ‘K’ key down until the entire contents are gone. Or you can delete the file and create a new one. Your choice.

With a fresh smb.conf you are ready to re-create a file based on your needs. A good configuration to start with looks like:

[global]
netbios name = NETBIOS_NAME
workgroup = WORKGROUP_NAME
security = user
encrypt passwords = yes
smb passwd file = /etc/samba/smbpasswd
interfaces = 192.168.1.1/8

[SHARE_NAME]
comment = COMMENT
path = /PATH/TO/SHARE
writeable = yes
create mode = 0600
directory mode = 0700
locking = yes

Where everything in ALL CAPS (as well as the interfaces line) is unique to your needs.

The SHARE_NAME is what you want to share out to your users. So if you are setting up a file server for a number of users you will want to have a directory, say /data, that is shared out through Samba.

Once you have the smb.conf file configured to suit your needs you are ready for the last steps.

Adding users

This is the step that most people skip and wonder why Samba isn’t working. For every user that needs to log in to the Samba server you have to add them with the help of the smbpasswd command. Let’s say I need to add the user “pickles”.  To add “pickles” I would issue the command:

sudo smbpasswd -L -a pickles

Now to make sure the users is enabled issue the command:

sudo smbpasswd -L -e pickels

Now restart Samba with the command:

sudo /etc/init.d/samba restart

Your Samba file server should be ready to go. Go to your windows machine and the Share should be visible. Double click on that share you and you will enter the username and password combination for any one of the users on the machine (as long as they were also added with smbpasswd). If you can not see it make sure your Windows machine is set up on the Workgroup.

After Samba is installed the smb.conf file will be around 533 lines long. Fear not. It’s much easier than it seems.

The smb.conf file is broken into sections. Each section will start with a line that looks like:

[TITLE]

Where TITLE is the actual title of the block. Each block represents either a configuration or a  share that other machines can connect to. You will, at minimum, have a global block and a single share.

Global

The global block is one of the more important blocks in your smb.conf file. This block defines the global configuration of your Samba server. This block begins with:

[global]

Within your blocks your configuration lines will be made up of:

option = value

statements.

The most important statements you will need in your global block are:
netbios name= NAME
workgroup = WORKGROUP_NAME
security = SECURITY_TYPE
encrypt passwords = YES/NO
smb passwd file = /path/to/smbpasswd
interfaces = ALLOWED_ADDRESSES

The values for each option above should be self explanatory. But there is one thing to note. If you are encrypting passwords you will need to add users (with passwords) with the smbpasswd command.
Within the global block one of the more important options is the security option. This option refers to authentication (how users will be able to log in). There are five different types of security:

• ADS – Active Directory Domain
• Domain – User verification through NT Primary or Backup Domain
• Server – Samba server passes on authentication to another server
• Share – Users do not have to enter username or password (until they try to access a specific directory)
• User – Users must provide valid username/password. This is the default.

Share Blocks

The next blocks will refer to individual shares. You will need a different block for each directory you want to share to Samba users. A typical share block will look like this:
[SHARE NAME]
comment = COMMENT
path = /path/to/share
writeable = YES/NO
create mode = NUMERIC VALUE
directory mode = NUMERIC VALUE
locking = YES/NO

Everything in caps above will be defined according to your needs. The tricky entries will be the create and directory modes. What this does is define permissions for any file created as well as the share directories. So the values will be in the form of 0700 or 0600 (depending upon your permission needs). Remember, you will need a share block for every directory you want to share out.

Naturally there are plenty of options that can be used in Samba. Many of these options will fall in the global block.

Printer Block

You can also define a block to share out printers. This block will start with:

[printers]

and will contain options like:
comment = COMMENT
path = /PATH/TO/PRINTER/SPOOL
browseable = YES/NO
guest ok = YES/NO
writable = YES/NO
printable = YES/NO
create mode = NUMERIC VALUE

Sample smb.conf

I have an external drive that I mount to /media/music and I share out to my home network with the following smb.conf file:
[global]
netbios name = MONKEYPANTZ
workgroup = MONKEYPANTZ
security = user
encrypt passwords = yes
smb passwd file = /etc/samba/smbpasswd
interfaces = 192.168.1.1/8
[wallen music]
comment = Music Library
path = /media/music
writeable = yes
create mode = 0600
directory mode = 0700
locking = yes

And that’s it. That is my entire smb.conf file. Granted I am only sharing out a single directory, but it shows how simple smb.conf can be to configure.
