I want to get the client machine name from the IP adress.
If I am getting the IP address of client from -
ip_addr = request.env['REMOTE_ADDR']

`nbtstat –a #{request.env['REMOTE_ADDR']}`
Ruby backticks run the resulting string at the command prompt.
But that probably gets you the name of their subnet router, not the literal machine. Then again, I know next to nothing about internet routing protocols, etc.

I'm unclear how to use the RESTKit 0.20.x API to set the request caching policy?
0.20.x not support caching policy?
Thanks
RestKit uses AFNetworking for the underlying network comms so you might want to look at this doc.
In general, yes, RestKit uses the standard caching offered by NSURLCache.

I have Server1 (Publishing server which has source code), Server 2 (Deployment server) and Clients machine which already has applications used and pointing to Server2. Would like to move this server 2 to new server and remove the server2. I do not want to change it manually in the client's systems. And this server 2 and new server are going to hold different IP addresses. How can i change the server 2 to new server. Please some one suggest me a solution ASAP.
Thanks :)
If you are using click-once deployment, you can change the DNS of the domain to point to the second server, and put the files in the same virtual path, There should be no problems.

How to send group sms using AT command?
In general, you can't. SMS PDUs are addressed to one number only; if you use your phone to compose a message to a group of people it actually creates a copy of the PDU for each recipient.
Unless you have access to a number that will take a received message and forward it to a group, you are out of luck I'm afraid.
this website has some good details of how to do it with hyperterminal or kermit

it works pretty well. although if your going to send a bunch of messages you should use some software that understands how to talk to the modem.

Given the account and password, how to obtain the contact list of that account in msn? Are there any msn api can do this? Or I have to use the account and password to login and obtain the contact list.
Is there a particular programming language that you wish to use?
There appears to be a PHP Class. You could also use something like libpurple to connect to the MSN network and download the list.
Officially the msn protocol isn't specified. But some people have been reverse enginering the protocol.
It's not an easy protocol, as you have to connect to several server before you have everything you need.
Note however that when microsoft changes the protocol again and drops old versions, you have to wait before the new protocol version is deciphered.
