I'm really new to IoT and its devices and need some recommendations about different devices. I need devices that be able to work with telephone network(e.g. SIM card) as well as working with internet.for example, can get commands from a service like SMS and apply it to the environment like house or can send information about house to the owner by SMS.
There is several IoT hardware like Raspberry Pi, Arduino and others depending on your requirements. You can use GSM shied extension for some hardware (e.g. Arduino GSM Shield) or external like modem dongle via USB Port for others.
Then, you can use C/C++, Java, Python, ... to do actions when receiving an SMS message.

Problem
I need a tool like Wireshark to capture outgoing and incoming packets. I searched the Wireshark documentation, but I didn't find any resources related to my question. There is probably some way to do it, but I don't know how to search for this efficiently.
For now, I am using Windows 10 for Education to sniff the packet formats that the monitor supports and expects from desktop applications.
Objective
My objective is to configure my monitor over HDMI (monitor supports it on Windows) when using Linux. Then, I will write a tool to do this and, barring legal obstacles, I will share it.
The Network vs HDMI
The reason that your computer can communicate with a remote server 1000km away is that your computer's network interface encapsulates data with control information. This enables the data to be transmitted over your broadcast domain (layer 2), the internet (layer 3), and a connection between the two devices (layer 4). Depending on the traffic you are sending, more layers/encapsulation may be involved here. Server fault has an answer that goes into more detail on OSI layers.
HDMI is more similar to a point-to-point connection here. There is no expectation that data needs to be sent to remote hosts such that routing/congestion information needs to be included. Wireshark is used to analyze network protocols, but won't be of much use to look at this raw data stream.
HDMI control libraries
You probably want to focus on sending a signal on CEC, HDMI's control wire. There are libraries such as libCEC, which has Linux support and can control this. If you wanted to programmatically control the link, you can, but you will likely need to buy a CEC adapter.

I am trying to chose an IP camera for outdoor surveillance, but I am not sure how I will be able to communicate with it. Afaik. these cameras have an IP address on the local network, which I can access to get the video stream. But what about the controlling part, like rotation, zoom, IR movement sensor, etc? Is there a communication standard for that, or should I try to find some kind of developer documentation?
I found that ONVIF is the most prevalent communication standard by IP cameras. https://en.wikipedia.org/wiki/ONVIF

To filter scammers, we validate user accounts with a sms verification system.
As you can imagine, some people are using virtual numbers.
Some MCCMNC can easily be banned as they are favored by scammers. But most scammer numbers have the MCCMNC of a "clean" telco.
How can we detect that?
You can try Nexmo Verify API to confirm that a phone number is valid, reachable and accessible by your user. Landline and mobile phones can be verified, while virtual and toll free numbers will be rejected. Trial service offers you 20 free verifications.
They have another product, Number Insight, which can be used to determine if a telephone number is a mobile phone, landline, virtual number or a Premium/Toll-Free number.

Any idea for TIPC protocol on Windows systems or any similar protocol which is available on windows ?
Thanks
Arpit
The Wikipedia basically says it's general-purpose communication library.
If you're designing an HPC cluster, take a look at "Microsoft High Performance Computing" in MSDN: http://msdn.microsoft.com/en-us/library/aa496121.aspx bot keep in mind that API only exists on some editions of their server OSes.
I think you'll only get better answer when you'll describe what kind of tasks are you going to accomplish.
P.S. I don't actually get the point of TIPC, even after reading the programmer's guide.
It seems using the API is not easier then using sockets.
But when you're using sockets, at least you've got tons of good books, online manuals, and easy to use debugging and diagnostic tools.

I wrote a windows program many years ago, which created music by sending notes to the "midi mapper" (and thence to the midi-synth on my sound-card)
Today, I have a soft-synth which, allegedly accepts midi information, so I'd assume it should be possible to use today's equivalent of a midi-mapper to route the midi output from my program to the soft-synth.
There's clearly no longer a midi-mapper application in windows, but my program still works (on XP) in that it drives the built-in soundcard synth, so there must be some sort of midi handling layer in windows. How can I get at this? And maybe redirect the midi to the soft-synth?
The default MIDI device can be set in Control Panel/Sounds and Audio Devices. If your soft-synth is registered as a MIDI device, you should be able to see it in the dropdown.
AFAIK most modern MIDI software now does its own MIDI routing from one device to another. Windows XP is limited in the number of MIDI devices it can support, and the MIDI software industry is gradually moving towards an all-USB model now.
In the USB model, many hardware controllers (such as this one) are "class-compliant", so you don't even need a special software driver to make them work.
For technical programming documentation about MIDI in Windows, this might be a good starting point.
