|

| 10 | <para>This parameter is a comma, space, or tab delimited
|
|---|
| 11 | set of hosts which are permitted to access a service.</para>
|
|---|
| 12 |
|
|---|
| 13 | <para>If specified in the [global] section then it will
|
|---|
| 14 | apply to all services, regardless of whether the individual
|
|---|
| 15 | service has a different setting.</para>
|
|---|
| 16 |
|
|---|
| 17 | <para>You can specify the hosts by name or IP number. For
|
|---|
| 18 | example, you could restrict access to only the hosts on a
|
|---|
| 19 | Class C subnet with something like <command>allow hosts = 150.203.5.</command>.
|
|---|
| 20 | The full syntax of the list is described in the man
|
|---|
| 21 | page <filename>hosts_access(5)</filename>. Note that this man
|
|---|
| 22 | page may not be present on your system, so a brief description will
|
|---|
| 23 | be given here also.</para>
|
|---|
| 24 |
|
|---|
| 25 | <para>Note that the localhost address 127.0.0.1 will always
|
|---|
| 26 | be allowed access unless specifically denied by a <smbconfoption name="hosts deny"/> option.</para>
|
|---|
| 27 |
|
|---|
| 28 | <para>You can also specify hosts by network/netmask pairs and
|
|---|
| 29 | by netgroup names if your system supports netgroups. The
|
|---|
| 30 | <emphasis>EXCEPT</emphasis> keyword can also be used to limit a
|
|---|
| 31 | wildcard list. The following examples may provide some help:</para>
|
