I have question how to make a program and then run it on 2 different computers, and then I'd like to somehow connect them together, so they could interact with each other. For example i type some text in program on my computer, and then text would show up on other computer.
Can you point me to some literature, or what should i look at to do something like this.
Here is a quick example of connecting two computers over a socket.

http://qt-project.org/doc/qt-5/qtnetwork-fortuneclient-example.html
Some related terms you should get to know are: TCP, UDP, IP, Socket, Port, IP Address
Qt makes most of the work of getting them talking to each other pretty simple.
Btw, at the time of writing, Qt 5.2 is the most up to date one to get.
Hope that helps.

I wanted to know if there was a way (APIs , Library) to monitor network activity on different interfaces (wireless , wired) being performed by applications triggered by different users on windows.
You want a program that can monitor various interfaces, log packets, and filter them based upon packet addressing, protocol, etc.
Look at the program called Wireshark/Ethereal (using Pcap), or Tcpdump.

I'm looking for a library to add a socks proxy option to a C/C++ program.
What libraries are available for unix and what is the best way to achieve this?
The solution should:
be considered best practice (safe)
work in multi-threaded programs with short single-threaded connections
easy to implement / maintain (if possible)
work for unix (linux/debian/ubuntu)
Found a lot of information on the internet but nothing specific, and don't know what to use or when to use it.
I do recommend:
libboost: http://www.boost.org/doc/libs/1_35_0/doc/html/boost_asio/reference/ip__tcp/socket.html
Qt: http://qt-project.org/doc/qt-5.0/qtnetwork/examples-network.html
Both are multiplatform and very good libraries, but Qt is for GUIs more than a simple library, so think about using libboost for this single purpose.

I want to build a transfer protocol on top of TCP to send a certain type of file between two computers. I was wondering if there were any Resources, open source projects or books that I could look at to get an idea of what I should be doing.
A good place to start would be the W3C HTTP/1.1 standard or the HTTP/1.0 standard if you want to implement something simple. You probably only need to implement the GET verb if you just wan't simple I/O. You could also look at implementing JSON as a data interchange format. If you're looking for information on how to implement a TCP/IP server too, then there are several books on the subject.

I want to monitor the performance of my application.
I wrote custom performance counters and monitored them with perfmon but since my application run on several machines I need a tool (open source ?) which can monitor the whole system (aggregate the same counters across the different machines, user-friendly display, graphs and so on).
On way to do so is to query the performance counter on all the machine using WMI and display the result with graphs and more I’m sure there are several solution for that and I would like to hear about them.
Thanks,
Ron Anavi

maybe someone knows a good crossplatform particle library?
I know Pyro particle library, but it's not crossplaftorm and free. There is also Magic Particles (Probably, the best version I need) but there is only theoretical possibility to make a port on Linux.
I'm not sure how good it is, but I remember seeing a post on www.gamedev.net on a open source particle engine written in C++. It appears to be graphics-library agnostic, so you should be able to easily port it to whatever platform you are interested in.
Here's a link:
