Connect and share knowledge within a single location that is structured and easy to search. I have setup samba share in Ubuntu What I can't figure out is, where nautilus stores samba share configuration. I would appreciate it, if someone could help me figure out the location of samba configuration file in Ubuntu.

There are a few exceptions:. Many applications, when stored on a remote system and run from a network drive, crash when the connection is dropped.
However, local applications simply accessing datafiles or documents on a network drive frequently experience no problems during the reconnection. Because a new copy of the smbd daemon is created for each connecting client, each client can have its own customized configuration file. Samba allows a limited yet useful form of variable substitution in the configuration file to allow information about the Samba server and the client to be included in the configuration at the time the client connects.
Variables can be used only on the right side of a configuration option i. An example is:. In this example, Samba assigns a unique path for the [pub] share to client systems based on what operating system they are running. Using variables in this manner comes in handy if you wish to have different users run custom configurations based on their own unique characteristics or conditions.
Samba has more than 20 variables, shown in Table This occurs before a connection to any share. This can change depending on the share. More about this issue is explained in Chapter 6 , when we discuss the force user option. Samba does not automatically create this directory if it does not already exist.
One way to solve this this problem is to instruct Samba to run an external program or script when a user connects to a specific share. More about this technique is discussed in Chapter 6. The [global] section appears in virtually every Samba configuration file, even though it is not mandatory.
If the section is not present, Samba uses the default values for all global settings. Any option that appears before the first marked section is assumed to be a global option. This means that the [global] section heading is not absolutely required; however, following the rule that it is better to explicitly state what you mean, include it for clarity and to protect your server against changes in default behavior in any future Samba releases.
There are two purposes for the [global] section. Server-wide settings are defined here, and any options that apply to shares will be used as a default in all share definitions, unless overridden within the share definition.
When Samba reads its config file, it creates a special internal service that contains the default values of all parameters. Any service parameters that you define in the [global] section are assigned to this list. When a client connects to the [test] share, Samba first consults the explicit parameter list for that share. Then it looks in the default settings for implicit option assignments.
Explicit settings take precedence over any compile-time or [global] defaults. If a [homes] share exists, smbd begins a search to validate the share name as a Unix username. If that username appears in the password database e. For example, assume that a client system is connecting to the Samba server RAIN for the first time and tries to connect to a share named [alice].
From this point on, the share [alice] is treated as a normal file share. Any variables are expanded according to the standard rules. For the sake of completeness, however, we will introduce a third built-in section.
This section, named [printers] , performs a service for system printers analagous to what the [homes] share does for user home directories. If it does, Samba creates a share named after the printer. Instead, Samba honors the Unix printer registry if you ask it to, and provides these printers to the client systems.
However, there is a potential difficulty: if you have an account named fred and a printer named fred , Samba will always find the user account first and ignore the existence of the printer, even if the client really needed to connect to the printer, assuming that both [homes] and [printers] sections are defined.
We revisit the [printers] section again in Chapter 7. When one of the Samba daemons is launched, it looks first at any configuration file specified with the -s option or in the default compile-time-defined location e.
There are two smb. These two options, along with the copy directive, which allows you to clone one share in smb. Specifies an absolute path to a file that should be read and parsed into the current configuration file.
The global config file option specifies a replacement configuration file that will be loaded when the option is encountered. If the target file exists, the remainder of the current configuration file, as well as the options encountered so far, will be discarded, and Samba configures itself entirely with the options in the new file.
Variables can be used with the config file option, which is useful in the event that you want to use a special configuration file based on the NetBIOS machine name or user of the client that is connecting. For example, the following line instructs Samba to use a configuration file specified by the NetBIOS name of the client connecting, if such a file exists. If it does, options specified in the original configuration file are ignored:. If the configuration file specified does not exist, the option is ignored, and Samba continues to configure itself based on the current file.
This behavior allows a default configuration file to serve most clients, while providing for exceptions with customized configuration files. The fundamental difference between the config file option and the include parameter is that the former completely replaces all existing configuration settings, yet the latter does just as its name implies: it inserts settings from an additional file in the current configuration. Figure illustrates how all three options override their previous values.
This option also can be used with variables for such purposes as including additional settings that differ for each client machine. If the configuration file specified does not exist, the option is ignored. Options in the include file override any option specified previously, but not options that are specified later.
Because the included file is inserted into the main file, beware of including global options into the section for a file or printer share as this will generate an error in the Samba logfiles. The majority of parameters can be overridden in an included file, but a few cannot. The workgroup and the server string directives are two examples of parameters that cannot be redefined.
The copy configuration option allows you to clone the configuration options of the share name that you specify in the current share. The template share must appear earlier in the configuration file than the share that is performing the copy. For example:. Note that any options in the [data] share defined prior to the copy directive are overridden by those from the [basic] share.
However, the top-down parsing of smb. We now start from scratch and build a configuration file for a new Samba server. Our goal is to create a working server and to examine the options that are important for basic functionality.
The server will export a single share named [data]. In addition, it places the system in the GARDEN workgroup and displays a description to clients that includes the Samba version number. The last two parameters explicitly relate to how Samba is to validate user credentials in connect requests. The security parameter value of user was not been explicitly mentioned.
Both parameters are covered in depth in Chapter 5 in the context of users and groups. Until then, the information you previously learned is sufficient for your current needs. Because this is a perfectly valid configuration file, it is possible to test it out. Create a file named smb. It might also be a good idea to test the new configuration using the same steps that you followed in Chapter 2.
After double-clicking the My Network Places icon on a Windows client, you should see a window similar to that in Figure You can verify the server string by either viewing the properties of the Samba host right-clicking the server icon to launch the context menu and selecting the Properties option , or enabling the details listing of hosts in the workgroup from the View menu.
In this case, with the exception of the built-in Printers and Faxes icon, the window would be completely empty, because there are no shares defined on the server yet. Table summarizes the server configuration options previously used. All three of these options are global in scope, so they must appear in the [global] section of the configuration file. For example, a system with the DNS name public.
One such reason might be if the hostname of the system is not unique because the LAN is divided over two or more DNS domains. Another use of this option is to relocate SMB services from a dead or retired system. The workgroup parameter sets the current workgroup or domain, as you will see in Chapter 9 and Chapter 10 in which the Samba server will advertise itself.
Because this is the default workgroup name of every unconfigured Samba system, we recommend that you always set your workgroup name in the smb. When choosing your workgroup name, make sure to avoid duplicating a name of an existing server or user. The server string parameter defines a descriptive comment string that will be associated with the server.
You can use variables to provide information in the description. For example, our previous example entry was:. So far we have not defined the [data] share on our server. So the next step is to create the directory tree on disk that will be exported, as well as the share section in smb. Samba requires that the directory path being shared actually exist in order for clients to connect it. The service details in smb.
The [data] share is typical for a Samba disk share. As a result, the read only option must be explicitly disabled for each disk share that is intended to be writable. Table lists the basic Samba configuration options previously introduced for disk shares. Specifies the Unix directory that will be provided for a disk share or used for spooling by a printer share. Inverse of read only. This option, which has the synonym directory , indicates the absolute pathname for the root of the shared directory or printer.
You can choose any directory on the Samba server. The comment option allows you to enter a free-form string that is transmitted to the client when it attempts to browse the share. A user can see the comment by using the Details view on the share folder or with the net view command at a Windows command prompt. For example, here is how you might insert a comment for a share:. This option allows you to specify the volume name of the share, which would otherwise default to the name of the share given in the smb.
If you copy the contents of the CD-ROM into a network share and wish to install from there, you can use this option to make sure the installation program sees the correct volume name:. The options read only and writable also called writeable or write ok are inverse Boolean options. Both default to enforcing read-only behavior on a file share but in a logically opposite fashion.
If you want to be able to write data to a share, you must explicitly specify one of the following options in the configuration file for each share:. Samba treats both parameters as the same feature. If you specify more than one occurrence of either or both options, Samba adheres to the last value it encounters for the share.
By default, both smbd and nmbd bind to all available broadcast-capable network interfaces on a system. There are times when you may wish to restrict this behavior, such as on a multihomed host that acts as a gateway from the internal network to the Internet, or perhaps on a laptop that has both a local network connection and a dial-up VPN connection.
Assume that our Samba server can access two subnets. The device eth0 is is bound to the If Samba is not supposed to advertise itself on the These two parameters, which are always used together, work in combination to restrict smbd and nmbd to the specified networks. The bind interfaces only option limits the behavior of smbd and nmbd to the subnets represented by the interfaces list. Writable — Enables users to read and write to the shared directory.
Visible — Grants read-only rights to users for the shared directory. On the Access tab, select whether to allow only specified users to access the share or whether to allow all Samba users to access the share.
If you select to allow access to specific users, select the users from the list of available Samba users. If you change this configuration file, the changes do not take effect until you restart the Samba daemon with the command service smb restart.
To specify the Windows workgroup and a brief description of the Samba server, edit the following lines in your smb. To create a Samba share directory on your Linux system, add the following section to your smb.
Encrypted passwords are enabled by default because it is more secure to do so. Graphical Configuration. Note The Samba Server Configuration Tool does not display shared printers or the default stanza that allows users to view their own home directories on the Samba server. Configuring Server Settings.
Managing Samba Users. Adding a Share. Descriptions — A brief description of the share. Writable — Enables users to read and write to the shared directory Visible — Grants read-only rights to users for the shared directory.
Command Line Configuration. From a Windows client you should now be able to browse to the Ubuntu file server and see the shared directory. To check that everything is working try creating a directory from Windows. Just make sure that the directory you want to share actually exists and the permissions are correct. Adjust the share and path names to fit your environment. It is a good idea to name a share after a directory on the file system. The guide is also available in printed format.
