Once built, a Samba server can be made a DFS server by setting the global + boolean <a class="indexterm" name="id2912593"></a><i class="parameter"><tt>host msdfs</tt></i> + parameter in the <tt class="filename">smb.conf</tt> file. You designate a share as a DFS + root using the share level boolean <a class="indexterm" name="id2912615"></a><i class="parameter"><tt>msdfs root</tt></i> parameter. A DFS root directory on Samba hosts DFS + links in the form of symbolic links that point to other servers. For example, a symbolic link + <tt class="filename">junction->msdfs:storage1\share1</tt> in the share directory acts + as the DFS junction. When DFS-aware clients attempt to access the junction link, + they are redirected to the storage location (in this case, \\storage1\share1). + </p><p> + DFS trees on Samba work with all DFS-aware clients ranging from Windows 95 to 200x. + </p><p> + Here's an example of setting up a DFS tree on a Samba server. + </p><div class="example"><a name="id2912656"></a><p class="title"><b>Example 17.1. smb.conf with DFS configured</b></p><table class="simplelist" border="0" summary="Simple list"><tr><td> </td></tr><tr><td><i class="parameter"><tt>[global]</tt></i></td></tr><tr><td><i class="parameter"><tt>netbios name = GANDALF</tt></i></td></tr><tr><td><i class="parameter"><tt>host msdfs = yes</tt></i></td></tr><tr><td> </td></tr><tr><td><i class="parameter"><tt>[dfs]</tt></i></td></tr><tr><td><i class="parameter"><tt>path = /export/dfsroot</tt></i></td></tr><tr><td><i class="parameter"><tt>msdfs root = yes</tt></i></td></tr></table></div><p>In the /export/dfsroot directory we set up our DFS links to + other servers on the network.</p><pre class="screen"> +<tt class="prompt">root# </tt><b class="userinput"><tt>cd /export/dfsroot</tt></b> +<tt class="prompt">root# </tt><b class="userinput"><tt>chown root /export/dfsroot</tt></b> +<tt class="prompt">root# </tt><b class="userinput"><tt>chmod 755 /export/dfsroot</tt></b> +<tt class="prompt">root# </tt><b class="userinput"><tt>ln -s msdfs:storageA\\shareA linka</tt></b> +<tt class="prompt">root# </tt><b class="userinput"><tt>ln -s msdfs:serverB\\share,serverC\\share linkb</tt></b> +</pre><p>You should set up the permissions and ownership of + the directory acting as the DFS root such that only designated + users can create, delete or modify the msdfs links.
