The <literal>services.transmission</literal> module

was enhanced with the new options:

Please <link xlink:href="https://github.com/NixOS/nixpkgs/issues">report</link>
|

any use case where this is not working well.
|
||||
In particular, the <literal>RootDirectory</literal> option newly set
|

forbids uploading or downloading a torrent outside of the default directory
|
||||
configured at <link linkend="opt-services.transmission.settings">settings.download-dir</link>.
|
||||
If you really need Transmission to access other directories,
|
||||
you must include those directories into the <literal>BindPaths</literal> of the service:
|
||||
<programlisting>
|
||||
systemd.services.transmission.serviceConfig.BindPaths = [ "/path/to/alternative/download-dir" ];
|

</programlisting>
|

</para>
|

<para>
|
||||
Also, connection to the RPC (Remote Procedure Call) of <literal>transmission-daemon</literal>
|
||||
is now only available on the local network interface by default.
|
||||
Use:
|
||||
<programlisting>
|
||||
services.transmission.settings.rpc-bind-address = "0.0.0.0";
|
||||
</programlisting>
|
||||
to get the previous behavior of listening on all network interfaces.
