Terminal Server via proxy server, IR port, and Repeater - Anyone tried this?
Here's a new idea, I think. Will it work?

New MessageTerminal Server via proxy server, IR port, and Repeater - Anyone tried this? (modified 0 times) busdepot
All of this talk of terminal servers has made me question whether my "homemade" solution can be applied to an epods.

I have a defacto wireless "terminal server" hookup between my PC, downstairs, and my television, upstairs. I use my TV to fully access my PC downstairs, without having any computer gear at all upstairs besides a keyboard, and without any wiring at all between the two rooms.

For data input, I keep a standard wireless infrared keyboard upstairs, transmitting via a commonplace 900 mhz IR repeater (i.e. X10 or Recoton) to the IR receiver port connected to my computer downstairs. To get the computer's audio/video signal to my upstairs TV, I use an X10 wireless 2.4 ghz video sender, hooked to the TV and audio out jacks on my video card, transmitting wirelessly to the audio/video inputs on my TV. This allows me to sit on my sofa upstairs and wirelessly operate my computer as though I were in front of it, without needing any computer gear upstairs or any network hookup at all. Basically a terminal server hookup that is platform independent. It's particularly nice for web surfing (within the resolution limits of a TV). I've been trying to think of how to apply this concept to my epods, for instances when my wife has commandeered the TV to use it for - gasp!- watching television!

I think I have an idea.

Apparantly you can establish an infrared (IRDA) connection between the epods and a pc. And I recently read, in another forum, that you can also use this connection for internet browsing. It said that if you install a basic freeware proxy server on your "host" PC, you can log on to the internet on your pc, connect your handheld computer to the pc wirelessly via the IR port, and browse the internet wirelessly from the handheld computer. (Would this work with an epods? The site was referring to handhelds in general, not epods specifically.)

So why not use this connection in conjunction with an IR repeater, just like the one I use for my wireless keyboard connection (above), to allow the use of the wireless connection room-to-room? The only difference I see is that you'd need two IR repeater kits, so you could put an IR sender and a receiver in each room, since the IRDA communication is two-way, as opposed to the IR keyboard's one-way signal.

Doing this, wouldn't it then be possible to connect to the internet wirelessly from the epods, using IR and a proxy server, without needing a wireless LAN setup (or any physical LAN connection at all)? As well as perhaps access other files on the "host" PC? Anybody tried this, or know why it wouldn't work? Any comments at all?

Sounds pretty cool. With the time and cash put into it you could probably get two wireless network cards (the main advantage to your other problem was having no computer hardware in the TV), but if you've got the time it ought to work. Just make sure and test the whole net sharing over serial thing first to see how it pans out. I'd imagine that you also might end up with some wacky data over you IR repeater that could potentially screw something up, but it ought to work.

I have an IR header on my motherboard... where should I go to find the right cable to mess with this? It'd be a heck of a lot easier to activesync via IR than fiddling with the serial cable every time. Plus I could goof around with those remote control programs.

Actually, the cost would be under $100 - a fraction of what it would cost to go the wireless LAN route. Serial IRDA adaptor for PC: about $40. Two infared repeater kits: about $20 each.

Regarding your question about getting an IRDA unit for your motherboard, check ebay; someone was selling a bunch of them there.

If you watch ebay, you can get wireless nics for $75 or so, and you can do adhoc mode with no AP if you want.

Actually, I was referring more to the labor cost than the material cost (lots of people here seem to be able to pick up all sorts of fun stuff for free anyway.) Of course, it's a hobby project so time is supposed to be spent. Your setup would be fine for sharing a modem connection or the like, but you'd be seriously limited beyond that. As MISman pointed out, a wireless ethernet bridging setup would cost about 50% more. It'd only take minutes to set up and you'd have all the functionality of the long-distance serial connection plus a whole lot more at a much higher speed (115kbps v. 10000kbps). Thanks for the idea on the ir cable. I really should have gone to this computer show that passed by a few days ago - could have gotten some cheap epods junk :)

Well, I agree that if all I need to buy is two wireless LAN cards (in ad-hoc mode), the additional cost versus the proposed IRDA option is not huge. But will this work if I also need to have a LAN connection to my DSL modem?

My pc has an external DSL modem hooked to the existing (wired) LAN card, using WinPoET software(PPPOE). To go wireless, would I buy a wireless LAN card for my PC (and one for my ePods) and install it in my pc _in addition to_ the existing LAN card (which is already connected to the DSL modem)? I was under the impression that to share the DSL connection via LAN (versus my IRDA solution), I'd have to buy a router (which would cost extra $$ and still would not be wireless). Can I just buy two wireless cards and no router?

Please excuse my inexperience with connecting to DSL on the ePods; I just upgraded from dial-up last week. (Been waiting forever for DSL to make it to this part of PA - it's finally here!) Your advice would be appreciated, as this is all new to me and not entirely clear.

That should be perfectly feasible. You'd have to have your DSL connected PC on at all times to work it though. You'd also have to install a software NAT program or the like on your connected computer (basically to do what a router would do). If you have Windows 98, ME, or 2000 it should already have a sharing feature built in. I know that in 2000/Whistler, you can right click on your ethernet connection and choose "share" and it'll start a dhcp server for your automatically. Pretty spiffy. I honestly can't give you a step-by-step on how to accomplish this, but I'm sure others here can. I imagine a good share of epoders use this type of connection method (ethernet connection + adhoc wireless).
