Since OS X This tells us that the Linux system is configured to use a DNS server located at The Now it is a simple matter of using the dns proxy option to tell Samba to use the DNS server:.

For this reason, we recommend you use dns proxy only to act as a supplement to your WINS server, rather than as a replacement for a DNS server. This is done with the global wins server configuration option, as shown here:. Note that because the request is directed at a single machine, we don't have to worry about any of the problems inherent in broadcasting. The order in which Samba attempts various name-resolution techniques is given with the name resolve order configuration option, which we discussed earlier.

The wins support and the wins server parameters are mutually exclusive; you cannot simultaneously offer Samba as the WINS server and use another system as the server! If you have a Samba server on a subnet that doesn't have a WINS server, and the Samba server has been configured with a WINS server on another subnet, you can tell the Samba server to forward any name-resolution requests with the wins proxy option:.

Use this only in situations where the WINS server resides on another subnet. Otherwise, the broadcast will reach the WINS server regardless of any proxying. Samba's name-resolution options are shown in Table Samba will provide WINS name service to all machines in the network if you set the following in the [global] section of the smb.

When set to yes , this option is mutually exclusive with the wins server parameter. Samba will use an existing WINS server on the network if you specify the wins server global option in your configuration file. For example:. For this option to work, the wins support option must be set to no the default. Otherwise, Samba will report an error.

You can specify only one WINS server using this option. This option allows Samba to act as a proxy to another WINS server, and thus relay name registration and resolution requests from itself to the real WINS server, often outside the current subnet. The WINS server can be indicated through the wins server option. The proxy will then return the WINS response back to the client.

You can enable this option by specifying the following in the [global] section:. This option allows you to run a script or other program whenever the WINS database is modified. The script would be specified in the Samba configuration file like this:. This will permit nmbd to query the server's standard DNS. You might wish to deactivate this option if you do not have a permanent connection to your DNS server. The global name resolve order option specifies the order of services that Samba will use in performing name resolution.

You can override this option by specifying something like the following:. You need not use all four options. This option is covered in more detail in Section 7. You should never need to alter this value. You should never need to change this value from its default. You should never need to alter this value from its default. Browsing was developed by Microsoft to help users find shared resources on the network.

In a networked computing environment where users can add or remove shares at any time, it is important to have some automatic means of keeping track of the shared resources and allowing users to "browse" through them to find the ones they wish to use. Before browsing was added to SMB networking, when anyone added a new share, the people with whom they wished to share the data or printer would have to be informed of the share's UNC, using some relatively low-tech method such as speaking to them in person or over the phone, or sending email.

Already, this was very inconvenient in large organizations. To further complicate matters, the users working on client computers had to type in the share's UNC to connect to it. The only way to get around typing in the share's UNC every time it was used was to map a network drive to it, and with a large number of shares on the network, this could easily get out of hand. To keep things simple, we will first describe network browsing in a network that contains only Windows systems and then show you how to add a Samba server.

The basic way browsing works is that one computer in the network takes on the role of the master browser also called local master browser , browse master , or browse server and keeps a list of all the computers on the local subnet that are acting as SMB servers. The browse list also contains the names of all workgroups and domains.

At this level, browsing is limited to the local subnet because the browsing protocol depends on broadcast packets, which are typically not forwarded to other subnets by routers. A user at any Windows system can view the browse list by opening up the Network Neighborhood or My Network Places , as we showed you in Chapter 1.

Or, the net view command can be used from a Windows command prompt:. Then, net view can be used with a computer name as an argument to contact a server directly and list the resources it is sharing:. The computers on the network involved in browsing are more than just the master browser and its clients. There are also backup browsers, which maintain copies of the browse list and respond to client requests for it.

Backup browsers are therefore able to take over the role of master browser seamlessly in case it fails. The master browser usually doesn't serve the browse list directly to clients. Instead, its job is mainly to keep the master copy of the browse list up-to-date, and also periodically update the backup browsers.

Clients are expected to get their copies of the browse list from backup browsers, selecting among them randomly to help to distribute the load on the backup browsers more evenly.

Ideally, the interaction between any client and the master browser is limited to the client announcing when it joins or leaves the network if it is a server and requesting a list of backup browsers. There can be more than one backup browser. For every 32 additional computers, another backup browser is added.

In addition to acting as the local master browser, the primary domain controller also acts as the domain master browser , which ties subnets together and allows browse lists to be shared between master and backup browsers on separate subnets.

This is how browsing is extended to function beyond the local subnet. Each subnet functions as a separate browsing entity, and the domain master browser synchronizes the master browsers of each subnet.

Samba can act as a domain master browser and can perform that task even in a workgroup network, which means that the Windows PDC is not required for this task. It is also possible to use the remote browse sync parameter to configure a Samba server to synchronize its browse list with a Samba server on another subnet. In this case, each server must be acting as the local master browser of its subnet. Unless it is configured never to act as a browser, each computer on the subnet is considered a potential browser and can be ordered by the browse master to become a backup browser, or it can identify itself as a backup browser and accept the role on its own.

When no master browser is running on the subnet, potential browsers choose a new master browser among themselves in a process called an election.

An election is started by a computer in the subnet when it discovers that no master browser is currently running. If a master browser is shut down gracefully, it will broadcast an election request datagram, initiating an election by the remaining computers.

If the master browser fails, the election can be started by a client computer that requests a list of backup browsers from the master browser or by a backup browser that requests to have its browse list updated from the master browser.

In each case, the system fails to receive a reply from the master browser and initiates the election. Browser elections are decided in multiple rounds of self-elimination. During each round, potential browsers broadcast election request datagrams containing their qualifications to notify other potential browsers that an election is happening and that if the recipient is more qualified, it should also broadcast a bid.

When a potential browser receives an election request datagram from a more qualified opponent, it drops out, disqualifying itself from becoming the master browser. Otherwise, it responds with its own election request datagram. After a few rounds, only one potential browser is left in the election. After an additional four rounds of sending out an election request datagram and receiving no response, it becomes the master browser and sends a broadcast datagram announcing itself as the local master browser for the subnet.

It then assigns runners-up in the election as backup browsers, as needed.
