Control home appliance over the internet

Hi .
I am doing a project using Java & C on linux to control a home appliance attached to my system.. it needs a little cheap electronic ckts ..and i have developed a small gui to control it ovwer the network. it works fine till there.. now i want to extend its functionality over the internet. The issues are
-> how do i identify the (ipadd) machine thats running my app if i use a dial up conxn where the ip add changes every session
( In short how do i control the machine @ my home from somewhere else like an internet cafe) ???
I use a datagram based socket & packet for implementing this.. any suggestions?

how do i identify the (ipadd) machine thats running my app if i use a dial up conxn where the ip add changes every session ?
"(ipadd) machine thats running my app" - Which machine are you talking about? You have 2 to 3 systems. One is your machine in Internet cafe and another is the home appliance. And/Or you can have a middleware machine in your home. Either way you should know the IP Address or URL address. Else you will not be able to connect.
how do i control the machine @ my home from somewhere else like an internet cafe) ???
You can have 3 systems. One in Internet cafe, second, a middleware machine in your home and third is your home appliance. The middleware has a application enabled by wired or bluetoothed to talk to the home appliance. The middleware can have a URL or IPAddress. Connect to this machine from your cafe and do the neccessary.
Good wishes,

Acessing Home Network Over the Internet

Hi,
I have a home network setup with a linksys BEFSR81 wired router with my iMac connected to the internet through it. I also have a PowerBook G4 that I use at my office. Using Apple's new ARD 3.0 software, is it possible to control and access my iMac through this setup. Note everything is set now to the most basic network setup. I am looking for something secure such as a VPN, how would I go about setting this up?

You would need a VPN Server capable router. The one's I have used are SnapGear (now CyberGuard) and Cisco. You might be able to get one from Linksys as well for cheap.
Your BEFSR81 also doesn't support Dynamic DNS services and is a pretty basic router relatively speaking.
This is not a trivial configuration and you willl need a lot of knowledge to get it accomplished.
If you can live with something less secure:
Step 1. Set the IP Address of your iMac manually.
Step 2. Forward ports 5900 and 3283 both udp and tcp to your iMac's IP address.
Step 3. Find out what is the WAN address of your router.
Step 4. On your Powerbook away from home, type in the WAN address in the addess field of ARD.
Step 5. Click "Control" on ARD and enter your short name and password of the iMac.
I would recommend you hire a mac consultant to make sure your network is secure if you are worried about vulnerabilities.
Good Luck.

How do I control my airport extremes/time capsules w/airport utility over the internet without mobile me? iCloud has disabled this function.

How do I use airport utillity with Time Capsule(or any airport extreme) over the internet without mobile me? iCloud has disabled this function. The mac's that I have not upgraded to icloud still see my routers over the internet with mobile me enabled. Are these routers obsolete now or will there be a firmware update to use icloud?

i want to do the same. i tried entering my @me.com account and does not work, but if I tried to go to icloud.com and using my @me.com works
why?
does the Airport express needs to be upgraded as well

Print to a printer wired to an airport extreme at home over the internet ?

Is it possible to print to a printer over the internet ? Anyone know how to do this ?

Hi Mark Craghill-
Can you be a tad more specific? Is this printer located on your same network or physically somewhere else? Wireless or wired network? Do you know the model of the printer? What are you trying to print from?

Best Way To Set Up Screen Sharing Over The Internet

What is the best/simplest way to set up screen sharing over the internet so I can remotely control my Mac at home from my Mac at work? My Mac at work is running 10.5.6, my Mac at home is running 10.4.11.

simplest
Get both Macs up to Mac OS X (Leopard). Then use Apple's MobileMe Back-to-my-Mac service.
Or, use iChat screen sharing along with the iChat free 3rd party Chax add-on which allows selected iChat Buddies to auto-accept an iChat screen sharing request. Free AOL Instant Messaging accounts can be used as the iChat accounts.
If you do not want to upgrade all systems to Leopard...
Next would be using the free LogMeIn.com account, or similar service. This will work
The above avoid needing to figure out how you get through the home routers, and provide encrypted screen sharing sessions.
After that you need to arrange for router port forwarding. If you want secure connections, then you should arrange to port forward the SSH port 22, then use ssh tunnels for VNC based screen sharing connections. There are GUI based utilities that will help setting up SSH tunnels. Do some searches over at VersionTracker.com or MacUpdates.com

How can I connect to my Mom's machine over the internet?

I installed ARD 3.6.1 on my laptop and was able to do a successful Intereact > Control to my Mom's machine from my machine while at her house, but when I went home to my house and tried the same thing I got the message:
"Connection failed to Mom's Computer. . . Please make sure that the Remote Mgmnt is enabled . . . Also make sure network connection is working properly."
Any clues?
Greg

Yes you can do this, connect to another computer over the internet using ARD--if you a person who likes to sleep on a bed of nails for the fun of it, who enjoys unanesthetized body piercings. But this product is not designed for this. It's designed for using on networked computers. After spending about ten hours tryng to make it work, I was finally told by a wise Apple support guy that while such a thing is possible, grasshopper. it's really hard and impractical, and even if you get it work, it probably won't stay working. I was given a refund and told to look for a more suitable product.
Voila, I found it! The logmein.com free product does everything I want. Everything! In less than 15 minutes.
My beef is with the Apple ARD website. Why don't they just say at the beginning:
Warning: Not designed to support your mother's frickin computer over the internet!
Would've saved 10 hours of grief and two calls to Apple Support.

OD over the Internet

Hi,
Is it possible to have OD athentification over the internet? Example if users in my network leave to go home they would still be able to connect to OD without having to connect to VPN?
Jeremie

If your workstations are bound to the OD domain and you are establishing users as mobile accounts (through MCX or profile manager) then your have the option of defining a cached account. In this method, the user must be on the LAN for initial account creation, then the user can use the system offline despite being an OD account.
Now, opening OD to the world is possible. But recall that you will need to open LDAP and Kerberos. And then you must protect against man in the middle attacks. I just prefer to not open up LDAP as it is world readable and if someone is doing intrusion discovery this is a great way of getting half of the keys to the kingdom.
If you have multple locations, then use VPN appliances to link your locations. Then use replica/relay servers to distribute your domain to the multiple locations.

How do I backup my time capsule to another time capsule over the internet

I have a Time Capsule that I use for backups locally within my own home. My parents have one as well that they use for their backups. Ideally it would be great to have my backups offsite -- if your house burns down it doesn't help that your backups were in the house...
So is there a way to copy (automatically) the image from one TC to another and vice versa over the internet?

No, there isn't, and even if there was, it would take forever, or possibly longer.
Any backup done over the internet will be quite slow; upload speeds are generally much, much slower than download speeds. Some of the companies that do internet backups, such as Mozy, Carbonite, etc., actually ship you an external HD for the first backup. You ship that back, they load it onto their servers, then do "incremental" backups of what's changed over the net.
In addition, it's not a good idea to back up a backup; any problem with the original will be copied to, and perhaps magnified, on the copy.
A much better approach is to get a portable external HD; do backups to it, then take it to a secure off-site location. See #27 in Time Machine - Frequently Asked Questions for some suggestions, especially the pink box there.
It still might be a good idea to have some limited data backed-up over the internet, such as relatively-small things and/or things that rarely change.

Can not view video over the Internet on WVC80N

I set up the web cam, set up the port forward etc so now I am able to:
   1. view/change web cam settings inside my home network.
   2. view video inside my home network.
   3. view/change web cam settings over the Internet.
But I am not able to view video over Internet. Every time I did so (using IE browser), after clicking the view video button, I got an error : There are too many user connections or the device is busy, please try again latter.
Anyone has a fix on this? I set up port forwarding on port 1024 (that's how I can chage settings over Internet).
I spent 2 hours on the phone with Linksys tech support but they could not find the reason.
Thanks,
Sam

Who is your ISP? How you are trying to access your Camera from the remote location? Along with Port 1024 you need to do port forwarding for port 80 on your router for the Cameras IP address. As WVC80N works on your HTTP Port.
To access your camera from the Remote location, you need to use http://wan ip:80.

How to share videos with family over the internet

I have a ton of home videos that I have edited with Final Cut and I would like to find a way to share those with family and friends across the country. Is there any way to do this in the Apple ecosystem. If not, what do most recommend as the best way to do this? Thanks

Thanks for the reply... I'm actually looking for something that would allow me to have all the content available in a library so friends and family can see all the content and then choose what to watch. Ideally, it would be like iTunes or iPhoto only that it could be accessed by multiple people from all over the internet. I think Apple is missing a huge niche in this area.

Access Time Capsule over the internet

Hey guys! I have a problem. I cannot access my Time Capsule over the internet.
I have a Time Capsule 2013 which connects to the internet using a PPPoE connection and which provides wireless connection to other peripherals in my house.
The TC is running the latest firmware and I've added my iCloud account in AirPort Utility settings, in order to access the TC over the internet, via Back to My Mac.
Whenever I'm away from home, I cannot access the TC.
I see it in Finder's sidebar, but whenever I press the "Connect As.." button I get the following error:
"There was a problem connecting to the server “Time Capsule”.
The server may not exist or it is unavailable at this time. Check the server name or IP address, check your network connection, and then try again."
I must add that I have a dynamic IP. Whenever the Time Capsule restarts, it gets a different IP.
Am I missing something?
Please help me. It's really important for me to be able to reach it when I'm away from home.

So the modem is bridged and the TC is doing the PPPoE authentication.. and it gets a public IP on the WAN interface.
The dynamic nature of the IP is not a problem with the BTMM and iCloud type system which should keep the intermediate connection in the cloud up to date.
What about the connection at the other side.. are you getting a public IP.. are you behind a firewall or restricted access? Remember both sides of this have to work.
See this thread.. you are not alone.. all is not sweetness and light unless you get a proper business account with static IP.
https://discussions.apple.com/thread/3699096?start=0&tstart=0
Apple info has a bit about issues that people experience.. and Tesserax has some setup info.
Remote Access
I would use the public IP and see if it works.. that means you need to check the IP before you leave home or use your phone tether and do the test at home so you can type in the public ip and use direct access .. at least to test it.

Time Capsule - how to gain "over-the-internet" access from Windows 7!

Hi guys,
I've been fighting for such a long time with my Time Capsule. I have no idea how to gain access "over-the-internet" on a PC (Windows 7) which is running on another network. My Time Capsule is set up with my Macbook Pro at home running Lion OSX, and i have internet connection. My brother who also uses Macbook has no problems connecting to my Time Capsule - through finder (connect to a server). But how do I gain "over-the-internet" access to my Time Capsule through a PC (Windows 7) from my office? Is there please someone who can guide me step-by-step, how to gain connection to my TC through a PC? Or maybe just an explantaion what has to be done on the PC before this thing can work out! This was the main reason to why i bought Time Capsule - besides of the Time Machine function. I also have an iCloud account (earlier Mobile Me), if that makes any difference.
Thanks!

There is no way to do it from windows direct to the TC.
It only presents AFP to the WAN side. And most ISP block SMB from internet access due to risks. There is AFAIK, no suitable AFP protocol utility for windows at the moment. If you google and find one, be aware it probably will not work to your satisfaction anyway.
You must use a Mac to access AFP but even then it is not a secure protocol and I would recommend against it anyway.
So basically if you had have asked before purchasing, I would have said, TC is unsuitable product. It is a backup drive for a Mac. It is not a NAS.. it is not designed for remote access by any computer other than a Mac. It does not support any other file protocol to the WAN interface.. and no secure protocol even there.
A NAS with Time Machine extensions from QNAP, Synology, Netgear all are designed for web access and are far more suitable. Researching a purchase beforehand is always worthwhile.
Anyway, your choices are.. return the TC and buy something more suited to the job.
Or if return is now impossible sell the TC on ebay.. etc and do the same thing.. buy a more suitable NAS.
Or buy a cheap mac mini (even second hand) and use that for communications with home.
Or, replace your current router with something that includes vpn. This is actually a good and commercially sound decision. VPN is generally used by business to connect to remote locations, because it is secure and will allow the greatest flexibility of connection. How hard or easy depends on the current setup. I would recommend a combined modem router with vpn server if you have adsl. Or for cable you can find plenty of routers with combined vpn. You can also use those for adsl if your ISP allows pppoe with bridged modem. The TC will have to be bridged as well. For other broadband it might be harder to find the right kind of box.
Once you setup a vpn you can access it from work using the appropiate vpn client in your work computer.

How can I download a file over the internet from a WebDAV server?

I am trying to download a file over the internet from a WebDAV server. I've tried doing it with Datasocket as suggested in these articles,
<a href="http://digital.ni.com/public.nsf/websearch/f3cc5f7e60a75cb2862567e700696abf?opendocument">Retrieving an Unformatted Text File via FTP or HTTP Using DataSocket</a>
<a href="http://digital.ni.com/public.nsf/websearch/4FA09E7B3674DA34C1256BD400555C41?OpenDocument">Download a Text File from a Password Protected URL Using DataSocket</a>
but all I get is error 1181 (protocol unrecognized by Datasocket).
I know I have the URL correct, because I can put it into a web browser and it works fine - I can download the file manually.
But I want to have a LabVIEW program do the download automatically.
I have the internet toolkit, but don't have the foggiest clue how to use it, and am using LabVIEW 7.1
I am a bit out of my depth here, so any advice welcome.
Regards,
Mark.

MIG,
What is the URL to the website? Is it an FTP site? The articles you referenced are for specific transfer protocols. If the stie you're trying to get to doesn't follow these protocols, then you'll get the error you're seeing. You may have to use ActiveX to control IE and download the files programmatically.
