| 7 | Defines whether to use the embedded code or start a separate daemon
|

| 8 | for the defined rpc services.
|

| 9 | The rpc_daemon prefix must be followed by the server name, and a value.

| 13 | Two possible values are currently supported:
|
|---|
| 14 | <programlisting>
|
|---|
| 15 | disabled
|
|---|
| 16 | fork
|
|---|
| 17 | </programlisting>

| 21 | The classic method is to run rpc services as internal daemons
|
|---|
| 22 | embedded in smbd, therefore the external daemons are
|
|---|
| 23 | <emphasis>disabled</emphasis> by default.
|
|---|
| 24 | </para>
|
|---|
| 25 |
|
|---|
| 26 | <para>
|
|---|
| 27 | Choosing the <emphasis>fork</emphasis> option will cause samba to fork
|
|---|
| 28 | a separate process for each daemon configured this way. Each daemon may
|
|---|
| 29 | in turn fork a number of children used to handle requests from multiple
|
|---|
| 30 | smbds and direct tcp/ip connections (if the Endpoint Mapper is
|
|---|
| 31 | enabled). Communication with smbd happens over named pipes and require
|
|---|
| 32 | that said pipes are forward to the external daemon (see <smbconfoption
|
|---|
| 33 | name="rpc_server"/>).

|

| 37 | Forked RPC Daemons support dynamically forking children to handle
|
|---|
| 38 | connections. The heuristics about how many children to keep around and
|
|---|
| 39 | how fast to allow them to fork and also how many clients each child is
|
|---|
| 40 | allowed to handle concurrently is defined by parametrical options named
|
|---|
| 41 | after the daemon.
|
|---|
| 42 | Five options are currently supported:
|
|---|
| 43 | <programlisting>
|
|---|
| 44 | prefork_min_children
|
|---|
| 45 | prefork_max_children
|
|---|
| 46 | prefork_spawn_rate
|
|---|
| 47 | prefork_max_allowed_clients
|
|---|
| 48 | prefork_child_min_life
|
|---|
| 49 | </programlisting>
|
|---|
| 50 |
|
|---|
| 51 | To set one of these options use the follwing syntax:
|
|---|
| 52 | <programlisting>
|
|---|
| 53 | damonname:prefork_min_children = 5
|
|---|
| 54 | </programlisting>
|
|---|
| 55 | </para>

| 58 | Samba includes separate daemons for spoolss, lsarpc/lsass,
|
|---|
| 59 | netlogon, samr, FSRVP and mdssvc(Spotlight). Currently five
|
|---|
| 60 | daemons are available and they are called:
|
|---|
| 61 | <programlisting>
|
|---|
| 62 | epmd
|
|---|
| 63 | lsasd
|
|---|
| 64 | spoolssd
|
|---|
| 65 | fssd
|
|---|
| 66 | mdssd
|
|---|
| 67 | </programlisting>
|
|---|
| 68 | Example:
|
|---|
| 69 | <programlisting>
|
|---|
| 70 | rpc_daemon:spoolssd = fork
|
|---|
| 71 | </programlisting>
|
