Thank you, most kind.

I should mention that I was trying to do this from the point of view of sharing a specific window with a friend, who is in a remote location. But I have no confidence that this is even possible (was hoping to do something clever with an X forward). So remote VNC it is.

One tutorial I've looked at mentions running "ssh -L 5900:localhost:5900 <hostname>" on the remote machine before running the VNC viewer - is that command necessary in addition to what we are trying to do, to create a tunnel? I think that port relates to VNC. Or does it relate to tightVNC specifically? Again, I dunno. I will try it out with this port though when I get home.

Cheers,
Matt.

Nope, it's connected directly to the Internet.

But I can ssh into the core, and then ssh into the desktop, so surely the problem isn't there in any event?

Is there perhaps some sort of special ssh permissions on the desktop I need to set, for when it is being ssh-ed into directly?

No idea.

Cheers,
Matt.

In Theory this should work, but havent tested it yet..

ssh your no-ip on port 10015  then the core will forward port 10015 to port 22 on your desktops IP. In the example the Desktop Ip would be 10.0.0.15.

Webadmin -- Advanced -- Network -- Firewall Rules.

Thanks for this.

Unfortunately my remote machine says "Connection refused". I have ssh-ed into the core, and then ssh-ed into the desktop in question without any problems. Firewall is set up with a port forward as per your example. Have also tried a few different ports.

Any clues?

Cheers,
Matt.

I should have said, the command I thought most likely to be appropriate was...

Code:

ssh -p1234 <MyExternalIP>

...but I wasn't sure where/what port 1234 was, or the correct way to set this/a port up in web admin. This port must relate to my desktop right?

Cheers,
Matt.

Have spent a lot of time researching this, and am struggling to sort fact from fiction, so thought I would ask my friends at LMCE.

I can ssh into my core using my no-ip IP address no problem, and I can ssh into my desktop from there (which sits on the internal LMCE network).

What I would like to do is remotely ssh into the desktop directly. I undertand this involves me forwarding ports on the router, but I am struggling to put the theory into context.

Could anybody tell me what I have to do to set this up in web admin, and the ssh command I would have to issue? I think I just need a real example to get my head round this.

Cheers,
Matt.

Thanks for the replies chaps.

That is exactly what I did - added the squeezeslave to a room with no MD. I have clearly misunderstood how this works. I created a new room specifically for the squeezeslave, in fact.

Am I supposed to create an MD first? If so, how do I do that without MD hardware?

Or am I supposed to be adding it to an existing MD i.e. the core MD in this case? If so, how do I tell LMCE to play audio to the squeezeslave, and not the MD (using the orbiter)?

Cheers,
Matt.

Andrew,

Thanks for the reply, very useful, as always.

I apprecate these multi-channels are a robust way of getting the desired result, but I really wanted to avoid shelling out for one of those (and having to deal with setting it up etc).

I believe I am right in saying that a Squeezebox has a built in speaker? And it cannot drive an amp? Although I guess if it has headphones output or similar, that can be used.

That Keene in-wall amp looks fantastic. At first I thought that £100 is a bit steep, but when you think that my solution requires a mobo (~£50), an amplifier (~£30) and PSU (~£20), and won't be as energy efficient, it makes an awful lot of sense. Thanks!

Just need somebody to sort this out for me now http://forum.linuxmce.org/index.php/topic,12605.0.html

davegravy,

I don't need the audio zones to sync. I have read a few threads about this, appears to be a common problem. Does the audio sync properly between MDs out of interest?

Cheers,
Matt.

I have two approaches in my head, and I don't know which one would be best.

I want some speakers in the garden and in the bathroom, which will require an amp of course. The amps I am looking at are just a cheapo low-power 2 channel things - I am not interested in rinsing hundreds of pounds on uber Denon rs232 controlled amps. So which is best...

1. Squeezeslave USB sound cards on the core, with the amps ALWAYS on waiting to be used. How much energy does an amp use when it is on, but nothing is playing? Is it recommended/safe?

2. Cheapo Atom boards for each zone, with the amp being powered off the PSU, meaning it will switch on and off when the mobo is switched on and off. Overkill? Or brilliant? Less energy usage, if a little bit more expensive?

I am leaning towards 2, it will work out cheaper than a squeezebox (or there won't be a lot in it at least). Or is there another approach that I may have missed?

Cheers,
Matt.

Brilliant idea, Langston. And a very good incentive. I look forward to judging everybody's hard work.

Cheers,
Matt.

I have 2 of these for sale, perfect working order, only selling because I have moved to an area where DVB-T reception is not good and have decided to either look at freesat, or not bother at all (and read a book).

http://wiki.linuxmce.org/index.php/Hauppauge_WinTV-NOVA-T-500

These are £60 new, so let's say £35 each (including p+p)

Cheers,
Matt.

I have followed these instructions to the letter (core only, adapter is plugged into the core) http://wiki.linuxmce.org/index.php/Squeezeslave_on_the_core

The only "extra" thing that I did (in that it's not spelt out to you to do it) was to put the MAC address in under the device in web admin on the A/V Equipment page. I assumed this was necessary.

Everything seemed to work perfectly; the adapter is showing under "lsusb", squeezeslave is definitely running. "squeezeslave -L" showed the adapter (but now that I have restarted, it is no longer there, is that normal?)

Anyway I get this message in the orbiter when I try to play a track...

"I cannot play this media. Perhaps there is not a valid device in this entertainment area capable of playing it."

And this was in /var/log/squeezeslave.log

Code:

I will tell you this... working from the graphics detection side of things for a while now...

Outside of the latest sandy bridge stuff... the intel graphics with the latest acceleration compliment is awesome. My archaic crap runs UI2 flawlessly. My newer intel stuff runs flawlessly and faster than my tried and true nvidia stuff.

nVidia has a lot of overhead not experienced by the intel stuff. Working on the backend... I am becoming a fast convert to intel fanboidom... now that we can use it

And for the record, I have never had to massage the ion1 at all... it just rocked out with its cock out by plugging it in and setting it to use vdpau in web admin.

If JaseP has encountered issues it would be my suspicion that EITHER he did not set vdpau in webadmin/media directors or he chose nvidia tnt2 or whatever over "standard video card" in webadmin/media directors.

I am not sure WHY this intuitive selection results in poor performance, but it does. It is my habit to disable the screensaver, because it is just a resource hog, but it runs without a hitch on that silly little Acer Revo 1600r

JaseP should drop into chat sometime.
I think things we would come to a less tentative relationship if he did. Limiting our interaction to 12 or so posts leaves a lot of misunderstanding in its wake, and he is a very smart guy who has helped me immeasurably, whether he knows it or not.

I think he thinks I don't like him, because I get frustrated at certain posts and have impulse control issues. I firmly believe he could be invaluable to the project if our conversations were not limited to misunderstandings.

I haven't been following closely enough over the past few months it would seem - are you saying that intel GPUs are now the same, or better than nVidia? Do you have a thread dedicated to your intel GPU work?

Cheers,
Matt.

EDIT: Sorry, found it http://forum.linuxmce.org/index.php/topic,12458.0.html

lazy 

Thanks for the thoughts. I echo most of the sentiment. I do have my hidden-away 10.04 core running quite nicely now but the reason I'm tinkering on the MD side is I'm trying to look at what sort of setup a less geeky person (than me, not you) might have- LMCE is all about devices, right, and what kind of lunatic has a server closet in his home? So if my father in law wants a setup, for example, I can't tell him to go "reboot the core"... no telling what he'll get up to. He needs a machine that sits next to the TV to put his beer on.

I digress...
Anyway, what *is* interesting is that you are pushing AMD.... which I haven't really looked at but will. And that, contrary to JaseP's previous quote, you seem to think Atoms will handle as MDs no sweat. Hmmmm.

I've always used AMD, more "bang for your buck" in my opinion. However I do use atoms as MDs which are intel of course. I always get dual core, I always get nVidia ion (has to be really), and I always get 2 GB RAM (and dedicate 512MB to graphics).

And I've got a server cupboard in my new place as well, it's the only way!

Cheers,
Matt.

I haven't read your whole post, but anyway...

Avoid hybrids, it means disturbing whatever is playing when you (inevitably) tinker with it. Get a dedicated core, and have low-power MDs (like atoms for example, some nice fanless ones out there) coming off that. I use gash PCs built from old bits in workshops, garage, etc as well.

As for choosing hardware, bog-standard is good. Cheap(ish) is good. Keep it simple, don't go for crazy motherboards with rocket launchers and flame-throwers, LMCE doesn't need it.

It's all AM3 processors and DDR3 RAM these days, so go for that. Assuming you are installing 1004 (you should), then most stuff should work. Cheapish dual cores or cheapEST quad core will do you, I've always used AMD. Cheap cases as well (I put the core where nobody can see it).

Also check out the user setup pages on the wiki.

Cheers,
Matt.

It also assumes you are happy to delete the files from your hard disk manually first.
