I wanted to read client side hardware configurations like RAM,Microprocessor,HDD etc from a server...And I couldnt find anything. Is there any way to get it
AIDA64, SiSoft Sandra, etc. I believe those programs would work. Kali Linux if you want a challenge.

I want to make my own ftp server software. I know, there are many ftp servers ready to install that have many features, but I still want to make my own, cause I can customize it and make it the way I want. Also, I find it fun to code, and I would rather make my own FTP server instead of downloading one that is ready to use if I have time. The problem is I can't find any information on how the protocol works and stuff like that. I would appreciate it if someone could explain how the protocol works or at least send me to a page that has useful information. Thanks!
If you are curious about beeing downvoted, here the explanation:
When planning a homebrew ftp program, it is a good point to google about FTP. Soon you will find RFC`S (that is "Request For Comment"), where things like the FTP protocol are described.
Thats a good starting point.
Then, when you have troubles with specific points, come back, show your code here, and ask for help.
I'm developing an app for filtering network connections from clients to my server (deny or allow to connect to my server).
I'm researching and found some resources like Windows Firewall API.
But I don't know if it's necessary for me or not.
What's the best API or solution to resolve it?
Thank so much.
regards,
Why don't you use an already-developed and proven app in the first place? If you really want to develop a filtering layer then what you need is a Filter driver and more specifically NDIS filter . A sample solution can be found here. But unless you are absolutely sure what you are doing and what you want to achieve I'd strongly suggest that you stick to an off-the-shelf solution - any firewall will be decent, or even a linux machine in front of your server with appropriate iptables rules.
Since you are working in a windows operating system. You would have to make use of Windows Filtering Platform as seen in the documentation on https://msdn.microsoft.com/en-us/library/aa366510.aspx
Drivers like TDS,LSP, and NDIS are all deprecated.
The programming language is C++. In my experience, it was a desktop application with the GUI in WxWidget and writing the filtering network connections hooks into the user mode.
There are two Filtering Layer Identifiers (Run-time Filtering Layer Identifiers and Management Filtering Layer Identifiers ), i made used of the earlier being that its more effective.
Should you need more assistance let me know.
Livelook.com "shares" screens without requiring shared parties to download nor install anything. These are my guesses on how it works:
Proxy server keeping track of shared parties who both are browsing the same website (thus not really screen sharing)
Interaction is being "recorded" by host side javascript and then serialized over to the client's javascript (ajax) who will then have to de-serialize the actions from the host and mimic the behaviour.
Anyone else has a take on this?
I did some research on this, and I'm pretty sure it uses Java since that is one of the requirements.

Here is perhaps how they get access to the screen:

But I'm a C++ man so, I wouldn't know if there's a better way to do things like that in Java.
I would like to set up a network with some computers I have, where they can connect to one main source, then receive and send messages back to it. I have never done any network programming before, so I'm just wondering what are the best tutorials using Ruby that I could use.
Thanks in advance.
There are about a billion ways you could do this. Could you post more about what the problem is you're trying to solve, or what the content/purpose/size/format/etc. of the messages is to be? Are you building something "for real" or just trying to learn network programming?
Also, do you already have the lower layer stuff figured out? You have networking infrastructure setup, IP addresses assigned, etc? If not, you'll need to get through that. Once you have that, you could start with a tutorial on basic socket programming in Ruby, but - depending on the answers to the questions above - you might not want to "roll your own" solution at that level. The answer might be to use an XMPP (Jabber) server, and use an XMPP client library, or you might want to deploy something like ActiveMQ, HornetQ, etc. and use a library for interfacing with that. Or maybe you want to use HTTP and pass messages around in JSON, or XML or $WHATEVER. In short, there are a LOT of options in this area.
I'm looking to start a MUD client application, which connects to a MUD hosted on a telnet server. The only thing important to me is that it runs painlessly and efficiently across any OS. Aside from that requirement, I'm not really sold on any language.
So I'm looking for a freely available telnet client library on which I can base my application, so I don't have to deal with the details of the protocol too much.
I would always consider Twisted for this kind of thing (Python).
The beauty is that if you later decide to swap it out to SSH or anything more secure than telnet, you can with little pain.
Twisted, twisted, twisted!
To use telnet, see package twisted.conch.telnet. It's got some spartan API docs, but the real information on using it comes from searching on Google Code Search, such as this nugget from grailmud - a MUD server.
For all of my MUD programming, I just created my own routines from the ground up using the RFCs.
In case you'd like to avoid some of my pain, I wrapped it up into a fairly simple C# class that handles Telnet properly. In case you'd like to peruse it, you can view it here.
This code has been copy/pasted and run on Windows and on Linux (through Mono) on a handful of separate projects and works pretty good.
There is a telnet interface in CPAN if you like Perl. It's pretty minimal, but it should get the job done.
[edit]
libcurl is also supposed to be able to do telnet, although I couldn't find any examples of it.
pmc ( http://sourceforge.net/projects/perlmudclient/ ) was an attempt to do exactly this. I've spent some of the last week going through it; it uses an older modified version of Net::Telnet to do its connectivity work.
My problem is that Net::Telnet seems to have a blocking interface when a partial line is sent by the server, i.e. a line not terminated by a newline. It has two features that support this (waitfor and its prompt mechanism), because almost all telnet servers have prompts that are not newline-terminated.
MUDs often have "prompts" that are non-standard and vary through the course of the game; the MUD I admin on has a "Your choice: " prompt as its login [it's not just for usernames], and many game features present alternative prompts. So I suspect you'll need to bear this in mind when you go looking for a cross-platform Telnet library!
If you like C, I heartily recommend libtelnet. It will maintain an internal state that does all the IAC sequence parsing for you, and handles option negotiation using the Q method.
