How is a local Debian server setup so that an iphone app in the simulator can communicate with it?
I want to send files and data to the server from an iphone app. and for now I would like it to be locally using the simulator, rather than a device using a router.
Enable NAT and you will find one network on the vm and two on the host computer, being one, a virtual network shared between the two of them. Then simply use their IP addresses as they appear in ifconfig.

I'm developing an iPhone app that connects to a server. For now, the server is running locally. In the iPhone simulator, I can connect to localhost and test it that way. However, this doesn't work running it on an actual device, because then localhost is the device itself.
Is there an easy way for the device to connect to the server running on the host computer? Or do I have to resort to putting the server somewhere else?
Rather than using localhost, replace that with your computer's IP address. That should work for both the simulator and device.
I have some problems communicating with different devices each other in my local network. I suggest some DNS problems or incorrect DNS settings
First of all, a short overview of my devices:
Router: Speedport W 921V (latest Firmware 1.22.) using also dyndns for remote operation
File-/Web-Server: Debian Squeeze running samba and apache
Client1: Computer using Win 7 Pro
Client2: Iphone/Ipad
Internet works fine on all devices! All clients have set the DNS to the IP of my router. The router also has the settings for port forwarding from port 80 to port 80 of my Webserver as well for port 8080. To access to my Webserver outside my local networks also works fine, but....
Problem 1) Resolving public dyndns-address
When I ping my public address mysubdomain.dyndns-home.com inside my local network, the IP will be resolved correctly without any timeout problems on all devices, but when I use my public address in a browser (Chrome, Firefox, IE) there is a timeout error message or server down message. This is the same behavior on all devices. So why can I not use my public address in my local network? To change that, what do I have to change?
Problem 2) Resolving local devices on Iphone/Ipad
Because I can not use my public address in my local network I want to communicate by my local device names. So all my devices are registered by their mac-address in the router. When I log into my router I can see all devices and their IP-addresses which are currently running. So if the router is the DNS for my clients, the router should resolve the local device names. That works so far for the Computers running Windows or Linux. But on my Iphone or Ipad the names will not be resolved. I also tried to refresh the lease or to forget the network and reconnect again, but still I can not communicate with my Iphone/Ipad and my other devices. So what can I do to resolve the names on my Iphone/Ipad?
Thanks for your help
1) Because you are in your local network you have to use private ip (you can see private ip using ipconfig on windows or ifconfig command line on linux). The public ip is for all others computers on the network. If you want test that the server works correctly you can use a proxy (like www.anonymouse.org)
I'm trying to test my iPad app which accesses a web service currently running on my machine. How can I make it so the app can make calls to the web service?
The easiest way would be to connect your iPad and your PC to the same wireless network.
Every computer in your network has an unique Network IP (Usually something like "192.168.0.100"). If you know how to to connect to localhost it usually suffices to change the localhost to the network IP of the computer you're trying to access,
If your machine is a mac, I had a similar question which was answered here. Enable web sharing on the mac and everything should be available to you.
I'm trying to test my iPhone application on the device.
I have a mac computer which stores my development environment.
Right now I can only access PHP files using the http://localhost/PHPFileLocation
which does not work when I try to test my app on real device.
How do I configure apache2 to be accessible from outside?
Is it possible to configure it to a specific IP address?
I want to reach some php scripts located on my development machine running apache2 from my iPhone device.
Thanks
If your computer has a WiFi card then you should be able to attach the iPhone remotely to a ad-hoc Wifi network created on your dev machine.
I'm assuming your Mac is behind a router. You should be able to configure your router to port forward connections to your WAN facing IP address to port 80 (the HTTP port) on your Mac - see http://portforward.com/ for some help.
You may also need to turn the firewall off on your Mac.
Once this is set up correctly you can hit http://yourexternalIP/PHPFileLocation in your iPhone app and this will be directed by your router to the Apache2 server on your Mac. The external IP is normally found on your router's admin page somewhere.
Is there any way I can capture network traffic (using application like Ethereal, on Mac ) while the application is running on iPhone and connected to xcode
Thanks
Connect you mac using an ethernet cable. Share your network connection on the mac over your AirPort. Attach the iPhone to your Mac's ad-hoc network.
Run Wireshark or HTTPScoop on your mac and you will be able to see all traffic from the iPhone.
I'm no aware of any way to do this for the WAN connection though. I'd be surprised if it is possible.
To capture packets from your iPhone using Wireshark, you have to first get your device id for the phone from iTunes. Plug in your iPhone via USB to your Mac...then open iTunes and click the iPhone icon in top navbar.
You can't copy the UUID, so you have to write it down manually. After you have the UUID, you'll need to mount the device.
Open a terminal and type: rvictl -s <device-id>
I created an alias in ~/.bash_aliases as alias mntios='rvictl -s <device-id>' -- as long as you have the same phone your device UUID won't change, even if you re-install the OS.
Once you have the device mounted startup wireshark. brew install wireshark (see: http://brew.sh)
One of the network adaptors should be rvi0 -- this is the network interface for your iPhone.
Now you can capture packets -- double click it to start capturing.
If you want to filter for specific urls you can type a filter like: http.request.full_uri contains <string-in-url> to filter requests.
On your computer, run an HTTP debugging proxy like Charles (Mac) or Fiddler2 (Windows). In the phone's wi-fi settings, turn on the HTTP proxy, entering your computer's IP address and the port number of the proxy. Make the sure the proxy is configured to allow connections from your phone. (It may allow localhost-only by default.)
