+7.3 Name Resolution with Samba</a></h2><P CLASS="para">Before NetBIOS Name Servers (NBNS) came about, name resolution worked entirely by broadcast. If you needed a machine's address, you simply broadcast its name across the network and, in theory, the machine itself would reply. This approach is still possible: anyone looking for a machine named <CODE CLASS="literal">
+fred</code> can still broadcast a query and find out if it exists and what its IP address is. (We use this capability to troubleshoot Samba name services with the <CODE CLASS="literal">
+nmblookup</code> command in <a href="ch09_01.html"><b>Chapter 9, <CITE CLASS="chapter">Troubleshooting Samba</cite></b></a>.)</p><P CLASS="para">
+As you saw in the first chapter, however, broadcasting&nbsp;- whether it be browsing or name registration and resolution&nbsp;- does not pass easily across multiple subnets. In addition, many broadcasts tend to bog down networks. To solve this problem, Microsoft now provides the Windows Internet Naming Service (WINS), a cross-subnet NBNS, which Samba supports. With it, an administrator can designate a single machine to act as a WINS server, and can then provide each client that requires name resolution the address of the WINS server. Consequently, name registration and resolution requests can be directed to a single machine from any point on the network, instead of broadcast.</p><P CLASS="para">
+WINS and broadcasting are not the only means of name resolution, however. There are actually four mechanisms that can be used with Samba:</p><UL CLASS="itemizedlist">

+Samba can use any or all of these name resolution methods in the order that you specify in the Samba configuration file using the <CODE CLASS="literal">
+name</code> <CODE CLASS="literal">
+resolve</code> <CODE CLASS="literal">
+order</code> parameter. However, before delving into configuration options, let's discuss the one that you've probably not encountered before: the <I CLASS="filename">
+LMHOSTS</i> file.</p><DIV CLASS="sect2">

+<A CLASS="title" NAME="ch07-pgfId-949950">
+7.3.1 The LMHOSTS File</a></h3><P CLASS="para">
+<I CLASS="filename">
+LMHOSTS</i> is the standard LAN Manager <EM CLASS="emphasis">
+hosts</em> file used to resolve names into IP addresses on the system. It is the NBT equivalent of the <I CLASS="filename">
+/etc/hosts</i> file that is standard on all Unix systems. By default, the file is usually stored as <I CLASS="filename">
+/usr/local/samba/lib/LMHOSTS</i> and shares a format similar to <I CLASS="filename">
+/etc/hosts</i>. For example:</p><PRE CLASS="programlisting">
+192.168.220.100    hydra
+192.168.220.101    phoenix</pre><P CLASS="para">
+The only difference is that the names on the right side of the entries are NetBIOS names instead of DNS names. Because they are NetBIOS names, you can assign resource types to them as well:</p><PRE CLASS="programlisting">
+192.168.220.100    hydra#20
+192.168.220.100    simple#1b
+192.168.220.101    phoenix#20</pre><P CLASS="para">
+Here, we've assigned the <CODE CLASS="literal">
+hydra</code> machine to be the primary domain controller of the <CODE CLASS="literal">
+SIMPLE</code> domain, as indicated by the resource type &lt;1B&gt; assigned to the name after <CODE CLASS="literal">
+hydra</code>'s IP address in the second line. The other two are standard workstations.</p><P CLASS="para">
+If you wish to place an <EM CLASS="emphasis">
+LMHOSTS</em> file somewhere other than the default location, you will need to notify the <EM CLASS="emphasis">
+nmbd</em> process upon start up, as follows:</p><PRE CLASS="programlisting">

+<A CLASS="title" NAME="ch07-pgfId-951120">
+7.3.2 Setting Up Samba to Use Another WINS Server</a></h3><P CLASS="para">You can set up Samba to use a WINS server somewhere else on the network by simply pointing it to the IP address of the WINS server. This is done with the global <CODE CLASS="literal">
+wins</code> <CODE CLASS="literal">
+server</code> configuration option, as shown here:</p><PRE CLASS="programlisting">
+[global]
+	wins server = 192.168.200.122</pre><P CLASS="para">
+With this option enabled, Samba will direct all WINS requests to the server at 192.168.200.122. Note that because the request is directed at a single machine, we don't have to worry about any of the problems inherent to broadcasting. However, though you have specified an IP address for a WINS server in the configuration file, Samba will not necessarily use the WINS server before other forms of name resolution. The order in which Samba attempts various name-resolution techniques is given with the <CODE CLASS="literal">
+name</code> <CODE CLASS="literal">
+resolve</code> <CODE CLASS="literal">
+order</code> configuration option, which we will discuss shortly.</p><P CLASS="para">
+If you have a Samba server on a subnet that still uses broadcasting and the Samba server knows the correct location of a WINS server on another subnet, you can configure the Samba server to forward any name resolution requests with the <CODE CLASS="literal">
+wins</code> <CODE CLASS="literal">
+proxy</code> option:</p><PRE CLASS="programlisting">
+[global]
+	wins server = 192.168.200.12
+	wins proxy = yes</pre><P CLASS="para">
+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.</p></div><DIV CLASS="sect2">

+<A CLASS="title" NAME="ch07-83429">
+7.3.3 Setting Up Samba as a WINS Server</a></h3><P CLASS="para">You can set up Samba as a WINS server by setting two global options in the configuration file, as shown below:</p><PRE CLASS="programlisting">
+[global]
+	wins support = yes
+	name resolve order = wins lmhosts hosts bcast</pre><P CLASS="para">
+The <CODE CLASS="literal">
+wins</code> <CODE CLASS="literal">
+support</code> option turns Samba into a WINS server. Believe it or not, that's all you need to do! Samba handles the rest of the details behind the scenes, leaving you a relaxed administrator. The <CODE CLASS="literal">
+wins</code> <CODE CLASS="literal">
+support=yes</code> and the <CODE CLASS="literal">
+wins</code> <CODE CLASS="literal">
+server</code> option are mutually exclusive; you cannot simultaneously offer Samba as the WINS server and point to another system as the server.</p><P CLASS="para">
+If Samba is acting as a WINS server, you should probably get familiar with the <CODE CLASS="literal">
+name</code> <CODE CLASS="literal">
+resolve</code> <CODE CLASS="literal">
+order</code> option mentioned earlier. This option tells Samba the order of methods in which it tries to resolve a NetBIOS name. It can take up to four values:</p><DL CLASS="variablelist">
+<DT CLASS="term">
+lmhosts</dt><DD CLASS="listitem">
+<P CLASS="para">
+Uses a LAN Manager <EM CLASS="emphasis">
+LMHOSTS</em> file</p></dd><DT CLASS="term">
+hosts</dt><DD CLASS="listitem">
+<P CLASS="para">
+Uses the standard name resolution methods of the Unix system, <EM CLASS="emphasis">
+/etc/hosts</em>, DNS, NIS, or a combination (as configured for the system)</p></dd><DT CLASS="term">
+wins</dt><DD CLASS="listitem">
+<P CLASS="para">
+Uses the WINS server</p></dd><DT CLASS="term">
+bcast</dt><DD CLASS="listitem">
+<P CLASS="para">
+Uses a broadcast method</p></dd></dl><P CLASS="para">
+The order in which you specify them in the value is the order in which Samba will attempt name resolution when acting as a WINS server. For example, let's look at the value specified previously:</p><PRE CLASS="programlisting">
+name resolve order = wins lmhosts hosts bcast</pre><P CLASS="para">
+This means that Samba will attempt to use its WINS entries first for name resolution, followed by the LAN Manager <EM CLASS="emphasis">
+LMHOSTS</em> file on its system. Next, the hosts value causes it to use Unix name resolution methods. The word <CODE CLASS="literal">
+hosts</code> may be misleading; it covers not only the <I CLASS="filename">
+/etc/hosts</i> file, but also the use of DNS or NIS (as configured on the Unix host). Finally, if those three do not work, it will use a broadcast to try to locate the correct machine.</p><P CLASS="para">
+Finally, you can instruct a Samba server that is acting as a WINS server to check with the system's DNS server if a requested host cannot be found in its WINS database. With a typical Linux system, for example, you can find the IP address of the DNS server by searching the <I CLASS="filename">
+/etc/resolv.conf</i> file. In it, you might see an entry such as the following:</p><PRE CLASS="programlisting">
+nameserver 127.0.0.1
+nameserver 192.168.200.192</pre><P CLASS="para">
+This tells us that a DNS server is located at 192.168.220.192. (The 127.0.0.1 is the localhost address and is never a valid DNS server address.) </p><P CLASS="para">
+Use the global <CODE CLASS="literal">
+dns</code> <CODE CLASS="literal">
+proxy</code> option to alert Samba to use the configured DNS server:</p><PRE CLASS="programlisting">
+[global]
+	wins support = yes
+	name resolve order = wins lmhosts hosts bcast
