<para>This option is used by the programs in the Samba
|
||
|
|
suite to determine what naming services to use and in what order
|
||
|
|
to resolve host names to IP addresses. Its main purpose to is to
|
||
|
|
control how netbios name resolution is performed. The option takes a space
|
||
|
|
separated string of name resolution options.</para>
|
||
|
|
|
||
|
|
<para>The options are: "lmhosts", "host",
|
||
|
|
"wins" and "bcast". They cause names to be
|
||
|
|
resolved as follows:</para>

address in the Samba lmhosts file. If the line in lmhosts has
|
||
|
|
no name type attached to the NetBIOS name (see the <ulink
|
||
|
|
noescape="1" url="lmhosts.5.html">lmhosts(5)</ulink> for details) then
|

any name type matches for lookup.</para>

<listitem>

<para><constant>host</constant> : Do a standard host
|
||
|
|
name to IP address resolution, using the system <filename moreinfo="none">/etc/hosts
|
||
|
|
</filename>, NIS, or DNS lookups. This method of name resolution
|
||
|
|
is operating system depended for instance on IRIX or Solaris this
|
||
|
|
may be controlled by the <filename moreinfo="none">/etc/nsswitch.conf</filename>
|
||
|
|
file. Note that this method is used only if the NetBIOS name
|
||
|
|
type being queried is the 0x20 (server) name type or 0x1c (domain controllers).
|
||
|
|
The latter case is only useful for active directory domains and results in a DNS
|
||
|
|
query for the SRV RR entry matching _ldap._tcp.domain.</para>

parameter. This is the least reliable of the name resolution

methods as it depends on the target host being on a locally

<para>The example below will cause the local lmhosts file to be examined
|

first, followed by a broadcast attempt, followed by a normal
|

system hostname lookup.</para>

<para>When Samba is functioning in ADS security mode (<command moreinfo="none">security = ads</command>)
|

it is advised to use following settings for <parameter moreinfo="none">name resolve order</parameter>:</para>
|

|
|

|
|
<para><command moreinfo="none">name resolve order = wins bcast</command></para>

|
<para>DC lookups will still be done via DNS, but fallbacks to netbios names will
|
||
|
|
not inundate your DNS servers with needless querys for DOMAIN<0x1c> lookups.</para>
