I would like to create an .exe app which allows me to connect
to my network share \\localcloud\public and then do a few things (update, copy files etc).
I know in Java there're few libraries like jCIFS, but I can't find equivalent in C++ language. I'm not interested to "mount network drive", just connect, do something with files and disconnect. Is it possible?

I'am completly new to SAS(and all these techincal things), but i need connect a network drive (or FTP?) to SAS, so i can copy or send files to it. I guess, it should look like another server at a workspace or something. I only know the address of it(maybe it will give you some clue):
\\10.48.42.166\exportsexternal1\oaDiez0Naf
The problem is even in that i don't know how to google it correctly - all link's are mainly about FILENAME in FTP
So, I have a desktop application and I want it to be able to check a website for new versions of itself. I am completely new to sockets (Windsocks and Berkeley), so before I invest time learning network programming I want some guidance to point me in the right direction.
The application is going to pretty much download an installation file from its website. The connection will not be secure as it doesn't matter if users can see it or not. Also the application's website will most likely be hosted # godaddy (in case somebody wants to be specific).
So my questions are; What technology should I be looking into, FTP, TCP or UDP? What are some things I should keep in mind as far as the client/server communication when it comes to file transfer with a remote server? Does anybody knows if godaddy allows this type of thing?
PS. If you think this might be a little too much to accomplish without enough theoretical/technical background, then please don't hesitate to recommend a book.
Use HTTP, and use a library to download a URL to a file. This should take 1-5 lines of code.
Why build a file transfer protocol yourself using sockets? Everything you need is built-in with HTTP. There are pre-made clients and servers available.
We are developing win-mac file sync installer which is quite similar to Dropbox. The installer is built with c++ and QT. We had a use case, where if the internet is disconnected(plugged out network cable (or) not connected to any wifi) so basically no access to web, During this case we need to make the installer into offline.
I tried few approaches like polling continuously to our web servers. If we are not able to reach then we detect as internet dis-connectivity. Due to some reasons we wanted to have clean native implementation which will look for machines network connectivity.
I even tried http://msdn.microsoft.com/en-us/library/aa965303%28VS.85%29.aspx for windows but this is failing in wifi cases even though we don't connect to wifi this example is saying "Network connected".
Can anyone suggest other alternatives. Platform specific solutions also invited.
You probably want to look at INetworkManager::GetConnectivity, and check for NLM_CONNECTIVITY_IPV4_INTERNET or NLM_CONNECTIVITY_IPV6_INTERNET in the response.
I'm building an app which upon login will connect you to certain ip addresses of which will also be running the same app.
The method of which i believe i should be using is direct tunnelling but as i say im a little new to c++, i have general coding skills, and i have sifted through a lot of forums and sites yet im still very unclear on what the best way forward is to achieve the requirement.
The reason for the connection will be to enable a secure chat, file transfer, and update software auto when connected to the program admin.
All those that have the app installed will once authorised, will be connected to admin client, then from that client all available ip's to connect to will become available to slave clients, this will increase the network size avilable to all users.
so the app needs to be able to handle ports but not via a server, instead it would be direct.
The connections also must ideally be encrypted.
Im kind of looking for what the application RetroShare does, but in text app.
(This is using C++ within Dev C++)
so just to recap, What method should i use to achieve the above?
I would take a look at SDL net to start with, its really simple to learn if you have never done any socket programming before.
for a secure connection you will probably want to start with TCP and then once you get the hang of network programming, start looking at other protocols.
Hope this helped! and good luck.
I'm in the process of creating a utility to backup user's media files. The media isn't being shared etc its only a backup utility.
I'm trying to think of the best way to protect users from ISPs accusing them of downloading illegal media files by using some sort of secure connection.
The utility is written in C++ using the Qt lib and so far I've only been able to find the QtSslSocket component for secure connections. The domain already has a valid SSL certificate for the next few years.
Can anyone suggest the best way to go about implementing this from both the server and client side. i.e what does the server need to have in place and is there anything in particular the backup utility needs to implement from the client side to ensure secure transactions?
Are there any known, stable sftp or ftps servers available etc?
As far as I know, Qt doesn't have support for secure FTP transfers.
Not sure what other info. would be useful to make the question any clearer but any advice or help pointing me in the right direction will be most welcomed.
EDIT I'm also Java competent so a Java solution will work just as well...
As Martin wrote, you can wrap client. But if you don't want to do that, you can use libssh.
I searched for some sort of solution to this for a couple days and then forgot about the problem. Then today I stumbled across this little gem in the Qt-Creator source Utils::ssh, includes support for SFTP, plain-old SSH, and all sorts of goodies.
Disentangling stuff from Qt-Creator can be a pain, but having gone through this process it amounts to grabbing Botan (one of the other libs in QT-Creator) + Utils.
When it rains, it pours, I find two solutions to this problem in an hour - http://nullget.sourceforge.net/ (Requires Chinese translation), but from their summary:
NullGet is written with Qt, runs on
multiple platforms, the GUI interface
of the multi-threaded multi-protocol
HTTP download software. Use NullGet
can easily download a variety of
network protocol data stream, faster
download speeds, support for HTTP, the
protocol currently supported are:
HTTP, HTTPS, FTP, MMS, RTSP. And it
can run on most current popular
operating systems including Windows,
Linux, FreeBSD and so on.
Easiest way would be to just wrap a commandline sftp client with a Qt front end.
On the server any ftp server should do sftp pretty much out of the box.
As Synthesizerpatel says Qt Creator implements SFTP. So I have isolated the library that contains SSH and SFTP and I have created a new project named QSsh in Github (https://github.com/lvklabs/QSsh). The aim of the project is to provide SSH and SFTP support for any Qt Application.
I have written an example on how to upload a file using SFTP in examples/SecureUploader/
I hope it might be helpful
