<para>
|
|
Defines whether to use the embedded code or start a separate daemon
|
|
for the defined rpc services.
|
|
The rpc_daemon prefix must be followed by the server name, and a value.
|

<para>
|
|
Two possible values are currently supported:
|
|
<command moreinfo="none">disabled</command>
|
|
<command moreinfo="none">fork</command>
|
|
</para>

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

Forked RPC Daemons support dynamically forking children to handle
|
|
connections. The heuristics about how many children to keep around and
|
|
how fast to allow them to fork and also how many clients each child is
|
|
allowed to handle concurrently is defined by parametrical options named
|
|
after the daemon.
|
|
Five options are currently supported:
|
|
<command moreinfo="none">prefork_min_children</command>
|
|
<command moreinfo="none">prefork_max_children</command>
|
|
<command moreinfo="none">prefork_spawn_rate</command>
|
|
<command moreinfo="none">prefork_max_allowed_clients</command>
|
|
<command moreinfo="none">prefork_child_min_life</command>
|
|
|
|
To set one of these options use the follwing syntax:
|
|
<programlisting>
|
|
damonname:prefork_min_children = 5
|
|
</programlisting>
|
|
</para>
|

Samba includes separate daemons for spoolss and the lsarpc/lsass,
|
|
netlogon and samr pipes. Currently three daemons are available and they
|
|
are called:
|
|
<command moreinfo="none">epmd</command>
|
|
<command moreinfo="none">lsasd</command>
|
|
<command moreinfo="none">spoolssd</command>
|
|
Example:
|
|
<programlisting>
|
|
rpc_daemon:spoolssd = fork
|
|
</programlisting>
|
|
</para>
