I wonder what will happen if I alter it to?

I don't think that will do much. Don't you really want to change the ath0/eth0 around so that eth0(your wired card) gets an external address from your IP providers DHCP and ath0(internal wireless) is fixed to an internal address.

Are you just trying to operate this as a standalone hybrid? If so, the I would pull the wireless card/adapter out and reconfigure with single wired network card. From memory (with Pluto, not linuxMCE but probably hasn't changed) the setup will allocate two interfaces on the one card.

Do you intend to have an internal network attached to your Core?

Point a browser to your core to get the admin interface.
Under Advanced->Network->Network Settings there should be a button called "swap interfaces"

You could create a C++ device quite easily and use that. It is not that hard.
Just make sure you have all the source for the release first, create the device template in admin, use DCEGen to generate the code.
Then build it, add a device using the new template and you are done.
It will have placeholders for all the commands that you want to implement. Try and use existing commands and command groups.

Check the documentation either here or on the Pluto site because others have already hooked up other general I/O boards. I keep meaning to hook one up myself, but I keep meaning to do a lot of things :)

Good work but perhaps this would be better put in the documentation (Wiki) perhaps.


Users / Re: How to add commands to xine-plugin
« on: May 14, 2007, 01:47:53 am »
All the following is for Pluto but should be the same for linuxMCE as far as I know.

You add commands through the Device Template. The best way is to search the commands to find one that already exists, see what command group it is in and add the group. Individual commands can then be switched on/off.

Once this is done then for a C++ device (like xine-plugin) you will need to regenerate the code and recompile.
You would be advised to get a release version of the source and make changes to that rather than work with the latest SVN code. Then try and merge your changes into the latest once you are happy with everything. This will ensure all the supporting libraries etc will compile and be what you expect.

To generate the code, get the DCEGen source and build that. Then run DCEGen from the source directory(which is in the same tree as everything else) with the device number for the template.

You should see placeholders in the code for your commands. Make changes as needed and use the Makefile to build.

You will then want to get the changes back into the main source so that you wont have to do this everytime.


Installation issues / Re: Smoothwall integration?
« on: May 10, 2007, 03:00:42 am »
Hi Chad,

I will have a go at answering some of your questions if I can. Others will probably add somre more...

1.  I run a stupidly confusing network.  It would be far too difficult for me to modify my wired connections and basically it just involves a lot of questionably placed switches (not routers or hubs).  To my point...  I am wondering if LinuxMCE has an easy to configure/use/modify firewall in it?  Right now I have a really nice small Smoothwall box as my router/firewall/DHCP/TFTP system and am wondering if LinuxMCE will be a drop in replacement for that (mostly wondering if it has an easy to work with firewall) or if I'll be shutting off *some* services but not all and running the 2 devices side-by-side?
Your CORE machine will act as a gateway and really prefers to operate with two network cards. By default it will want to act as your firewall/DHCP server and TFTP server. There is an easy to use Firewall admin screen (part of the standard admin server) that has worked well for me. So basically it should fully replace the smoothwall server (which is exactly what I did).
The only thing to be careful of is that most of the standard network configs (ie: your /etc files) are extracted from the database at each reboot so changing them directly is typically not effective. They can be directly changed in the database or alternatively (and preferably) altered through the Admin screens provided.

2.  I have a pretty decent MythTV arrangement.  A single master backend and several frontends one of which is netbooting.  Will I be able to move the single master backend to a slave backend to keep all the recording data intact and not have my recordings turn into their filenames?  Will the netbooted frontend just *work* once I install MCE (assuming I just disable my Smoothwall setup all together?)?  Basically, will I lose any of my existing MythTV functionality?  I'm hoping for all gravy and no lumps.  ;D

This one might be better for MythTV forums, but I would be looking at seperating them completey to start with and migrating your current backend data to the new master backend (CORE machine) and getting everything working and then look at adding the old stuff in. I am still not happy with my MythTV setup but have not put much time into it as the Wife is very happy with the current TIVO setup that is operating and until I can offer something better the cable box etc will stay attached to that.
With your experience with MythTV it sound like you should be able to add some real value here.
Standard frontends should still work fine with the CORE as a backend.
Your netbooting machine when added to the Pluto network should just boot up as another Media Director.

3.  I have just a little bit of confusion on connectivity.  I have enough Bluetooth adapters for all of my systems.  Does this mean I can forego any IR or Serial arrangements?  I see that a specialized (somewhat expensive) switch that includes IR and Serial ports is suggested (something like GS-110 comes to mind but I can't quickly find the wiki page that talks about it).  If I go all Bluetooth (just for control, I have wired ethernet for connectivity) does that mean I can ignore any IR info?  I do have a projector as one of my displays and it has a serial connector on it (which I assume means I can have my LinuxMCE system in that room control it) but for now I am not interested in that (awesome) feature.  Is that about the extent of why I would want the rather expensive serial/IR/switch device?  If I don't include it now, will it be painfully difficult to integrate later? 
The bluetooth adapters are at the moment only used for Mobile Orbiter communications and "Follow Me" type functionailty (working out what room you are in). In theory they could also be interface devices for other devices (much the same way IR is used) but to my knowledge it is not doing this at the moment.
The question on how to control your passive (non IP) devices is really down to how they can be controlled. IR seems to be the lowest common denominator. A GC-100 may be what you are talking about, but they are not that expensive. If anything requires IR control then you will need an IP controlled IR transmitter of some sort. There is a few options, the GC-100 is one.

4.  Light control.  Looks very awesome!  High "wow" factor, but low usability factor, for me personally.  So I'm wondering, (subectively of course) if it's worth it.  How difficult is it to get it working, what are some of the costs I might expect, and do any lights work (is it a plug replacement or a bulb replacement or what...)?  I briefly have read about Zwave but nothing difinitive really seems to be available to the average joe consumer with a lot of time, a little bit of extra money, and a desire to learn.
I am still in the same situation here. I am waiting until ZWave becomes a bit more available in Australia - but from what I have read you should be able to replace your light switches, add a USB controller to your network and go from there. Much the same as setting up X-10 I imagine but signals are sent via RF rather than over the wires.

Anyway, hope I have helped a bit.

It uses LIRC so anything that is supported by that I guess.
Try for more

In the PlutoHome distribution there is built in checks in some of the scripts that enforce the same Kernel version on the Core and the MDs. I am not sure if this has been removed for linuxMCE or not, but it is something to look out for.

You will have to be carefule that setup scripts don't overwrite any settings changes you manually make.

If you just need a couple of config changes to the kernel, I would recommend getting the sources from the linuxMCE repository and changing that and rebuilding, rather than getting a fresh set of kernel sources.

Let us know how you get on.

No problem, keep in mind though that what I was describing was this product (linuxMCE) not necessarily linux in general.

Despite its name, linuxMCE could really run on any operating system. Sorry to probably be even more confusing.

« on: April 27, 2007, 01:55:42 am »
I have been meaning to try something similar with DSL but time hasn't allowed it yet.
My plan was to build a minimal installation which acts as a Media Director but perhaps audio only and with on Orbiter.
The intention would be to utilise very old, low memory, low CPU power PCs that I have.
So far I have got as far as putting DSL on one and playing around a bit. I have not put any Pluto(linuxMCE) software on it yet.
I am yet to determine how much Kernel reliance there is though.

Hopefully I will get to do some more on it soon.

what is media director? is it similar to MythTV, or is more like a presentation software comparable to powerpoint? If it is like mythtv, which one is better? or does it depend on what you are doing?

The complete linuxMCE system consists of a central CORE computer which typically has lots of disk space and memory and hosts things like TV cards and Asterisk cards. Media Directors are PCs that typically are put in each entertainment area to play the centrally stored media. They have software wrappers around standard Linux open source products like MythTV, Xine, Asterisk etc. They are controlled by Orbiters which are the GUI for the system. Orbiter software can run on the Media Directors themselves or on other devices such as PDAs or Mobile Phones or even accessed through a web browser.

Hope that helps

No, I was wanting to have everything running off of the CF drives.  (solid state, no unnecessary network traffic)


Theoretically this is possible, but from the looks of the MD installation they have not tried to trim this down at all so it would require work.

Any reason why you think that this would be preferable over a network boot. I think the network booting is one of the best parts of the system. Keep in mind that the MD mounts the media shares from the core anyway - so they might as well mount their whole OS. They certainly could not run standalone.

I would be interested to see how you get on with it though.

You need to initiate a PXE network boot. This is usually done by a BIOS setting as you know, however it is just a piece of software that needs to be run and can also be loaded on another boot device.
I have successfully done this on to a floppy disk, but can see no reason why it couldn't go on other devices such as a CF hard drive or CDROM.
There is software available on the net which assists in building an image that can be written to the boot device.
You need to know exactly what network card (chipset) is in use.

Hi Bill,

A media director can operate totally diskless as they will network boot and utilise mounted network shares on the CORE machine.

Or are you talking about the minimum memory needed to operate as a Media Director?
The memory usage is dependant upon the devices installed and running on the MD. The big consumer of memory seems to be the OnScreen orbiter (especially if it is OpenGL). This then acts as a parent for most of the "Player" devices which are wrappers around the software that actually does the work (eg: Xine, MythTV etc). There is also a matching Plugin device running on the Core which enables the streaming aspect to work as well as Media selection etc.

A MD needs the minimum specification of whatever applications are used (eg: Xine).

In theory, there is is no need for an MD to run an OnScreen orbiter and still have devices installed and running, but I have not done this and I am not sure if anyone has.

I hope this has helped

Not sure if it helps your situation, but you can switch your network interfaces via the Network Admin screen.
This will change which interface is used for internal and which for external.
