<description>
|
|
<para>A synonym for this parameter is <smbconfoption name="allow hosts"/>.</para>
|
|
|
|
<para>This parameter is a comma, space, or tab delimited
|
|
set of hosts which are permitted to access a service.</para>
|
|
|
|
<para>If specified in the [global] section then it will
|
|
apply to all services, regardless of whether the individual
|
|
service has a different setting.</para>
|
|
|
|
<para>You can specify the hosts by name or IP number. For
|
|
example, you could restrict access to only the hosts on a
|
|
Class C subnet with something like <command>allow hosts = 150.203.5.</command>.
|
|
The full syntax of the list is described in the man
|
|
page <filename>hosts_access(5)</filename>. Note that this man
|
|
page may not be present on your system, so a brief description will
|
|
be given here also.</para>
|
|
|
|
<para>Note that the localhost address 127.0.0.1 will always
|
|
be allowed access unless specifically denied by a <smbconfoption name="hosts deny"/> option.</para>
|
|
|
|
<para>You can also specify hosts by network/netmask pairs and
|
|
by netgroup names if your system supports netgroups. The
|
|
<emphasis>EXCEPT</emphasis> keyword can also be used to limit a
|
|
wildcard list. The following examples may provide some help:</para>
|
|
|
|
<para>Example 1: allow all IPs in 150.203.*.*; except one</para>
|
|
|
|
<para><command moreinfo="none">hosts allow = 150.203. EXCEPT 150.203.6.66</command></para>
|
|
|
|
<para>Example 2: allow hosts that match the given network/netmask</para>
|
|
|
|
<para><command moreinfo="none">hosts allow = 150.203.15.0/255.255.255.0</command></para>
|
|
|
|
<para>Example 3: allow a couple of hosts</para>
|
|
|
|
<para><command moreinfo="none">hosts allow = lapland, arvidsjaur</command></para>
|
|
|
|
<para>Example 4: allow only hosts in NIS netgroup "foonet", but
|
|
deny access from one particular host</para>
|
|
|
|
<para><command moreinfo="none">hosts allow = @foonet</command></para>
|
|
|
|
<para><command moreinfo="none">hosts deny = pirate</command></para>
|
|
|
|
<note><para>Note that access still requires suitable user-level passwords.</para></note>
|
|
|
|
<para>See <citerefentry><refentrytitle>testparm</refentrytitle>
|
|
<manvolnum>1</manvolnum></citerefentry> for a way of testing your host access
|
|
to see if it does what you expect.</para>
