So I have some specific environment (like linux os based phone) so I have no such thing like terminal. All I can do is create my own UI's using C++ and some SDK I am provided with.
I want to create an ssh client application for my device. Its not a work, nor a homework - just for fun that means I have lots of time for solving conflicts that may appear.
My main problem is I have never worked with OpenSSH as a lib... and when I look on it it seems some large mountain to me.
So I ask for your help - have you seen any open-source ssh clients that use SSH methods with their own UI's based on OpenSSH or, better Portable OpenSSH?
PuTTY for example.

I am trying to create a signal/textsecure client using qt and C++, however i cant seem to fibd any C++ bindings for it.
the only bindings i can find are for Go (https://github.com/nanu-c/textsecure/)
is there any way to connect C++ with signal?
edit:
i wanted to clarify some things:
-im talking about the messaging app called Signal (https://signal.org)
-i am trying to write an app for ubuntu touch and am developing on manjaro linux.
On Linux or Unix, you probably want to communicate with other remote applications using some communication protocol, such as HTTP or HTTPS or SOAP or JSONRPC or ONCRPC. Of course read about socket(7) and before that Advanced Linux Programming then about syscalls(2). Consider reading a textbook on Operating Systems
Be sure to study the source code related to Signal. Read their technical documentation.
You surely need to understand the details. So take a few days or weeks to read more about them.
If you want to use some web service, you need to read and understand its documentation and when and how you are allowed to use it. There could be legal or financial issues.
Then you might use HTTP related libraries (e.g. Wt or libonion server side, and libcurl or curlpp client side).
See also in April 2020 the ongoing HelpCovid free software project (for Linux), at least for inspiration. We are coding it in C++.
after a little more digging i found that textsecure bindings are now renamed to libsignal.
after finding that out i found a lib for c/c++

I'm looking for some pointers for writing a firewall program which denies every port/ip at first and creates rules by asking you whenever a program wants to access the internet, much like the discontinued product Kaspersky Anti Hacker for Windows. I especially want to use it on web browsing. So if my web browser wants to access stackoverflow.com the program should ask me if it should make a connection to stackoverflow.com's ip address, or when torrent client wants to connect a peer It should ask to either allow that port or allow that ip/port only.
I have used gufw but I have to know the port/ip before adding the rules so it isn't as I want it to be. I'm also trying to stay out of Firestarter since the last release was in 2005. So I have decided to write my own.
I just need some pointers on this subject. It can be a terminal command to see the connections I make with other computers, or a way to prompt before making connections, an open source project that sounds like this, or a c++ library/shell program that I can use to write a program for this... Any lead at all would suffice.
If you could point me in the right direction, I would appreciate it.
PS. I am familiar with c++ and shell and php but that's irrelevant.
Hmm, you seem to be interested in Windows only. If so, you might wish to look at Windows Layered Socket Providers (LSP) infrastructure.
In short, you can write DLL, which would be automatically loaded into any application that uses Winsock. This DLL can intercept calls to any Winsock function like connect(), send() and etc. When such call is intercepted you can show user some window asking if he wish to connect to this address.
So, this can be used to build such firewall application you are thinking of.
There should be a lot of documentation on how to create LSP's on Microsoft site, but i remember especially nice example by Komodia company - http://www.komodia.com/lsp/lsp-sample.
I want to implement WiFi manager program which should handle the following.
notification on wi-fi access point has come or gone
provide information of available wifi access point
connect/disconnect with a given wi-fi access point
Which is the recommended C/C++ WiFi library for Linux to achieve this?
On Fedora (at least), the preferred way to interact with NetworkManager is via DBus.
While wireless-tools and the like will work — even direct kernel calls, if you must — there are a couple of problems:
You'll probably need superuser privileges
NetworkManager will probably have a panic attack and get into fights with you, unless you stop its service
The user's normal networking controls (e.g. desktop tray icons) are almost certainly configured to use NetworkManager.
You can send and receive DBus messages for all the tasks you mentioned, for WiFi as well as arbitrary other types of network interfaces. The API is published here, for version 0.8.
For newer operating systems, there are apparently changes in the API, with a migration guide.
Their wiki should be really helpful.
I know both Fedora and Ubuntu use NetworkManager by default; I believe many other systems do, as well, but don't have an exhaustive list.
Of course, if you're using an embedded system, custom distribution, or something, then your mileage may vary.
That would be wireless-tools
I would recommend using directly the NetworkManager Library.
You can use low-level D-Bus library or libnm-glib library, that makes communication easier: example add connection glib
For more info, you can take a look into the code of the command line client nmcli.
i am trying to create a C++ program on Windows machine which has to execute a program on remote machine, transfer the generated file to local machine. The remote machine is also windows.
Is there any efficient method to implement it without using MFC? Is it possible to do it without server/client component?

I don't recommend coding your solution since other solutions already exist. One of them is Rsync, which is pretty popular in *nix circles.
A Windows friendly version also exists, and it's called DeltaCopy.
Unless you're trying to improve your skills, or have the time, or you believe you can do better, stick with proven solutions.
There are any number of windows remote shell solutions that will allow you to do this without programming. You can also use a remote desktop client.
use ftp command from c++ or Cleint/Server.
I have to program a C/C++ application. I have windows and linux (ubuntu 9.04) in my machine, and can program in both of them (via gcc/code blocks/vim,etc). The problem is that the executable is going to be run in a Unix (not linux) machine (will have access to it in about 20 days).
My Team Leader doesn´t want all of the code to be programmed in linux - unix. So, some of it will have to be developed in windows (and then many prayers will follow so that nothing bad happens).
The best thing i´ve come up with is to program remotely on the server, from windows and linux, so every programmer (only me for the next 2 weeks) is sort of happy.
In windows, I think i´m stuck with putty, but is there any alternative on linux, rather than ssh-vim? .
I read this Remote debugging with Eclipse CDT but it didn´t bring much light on the subject. At least not much hope.
There is another issue. I don´t consider C/C++ to be a portable language. At least for real programs. Sure it compiles, but many issues will arise, even with boost / stl. I haven´t taken a careful look to the code, but still, how wrong a I?
Any tips will be greatly appreciated.
Thanks in advance.
You could ssh w/ xming for a gui ide/editor that is on the remote machine.
If all the code is one the remote machine and compiled there, don't you have to worry about developers trying to work with the same resources? Also might the machine/network not be able to handle multiple ssh connections if you're using xming?
If you can convince your system administrator to install the libraries (an X server is not required), you can use X forwarding with SSH, which will allow you to execute X apps remotely and have them come up on your local server. If you're using Linux locally, you probably have X running already, and if you are using Windows, you can use the Xming server (with a little configuration to get it to accept remote connections). For debugging, if you need a separate shell, just set another instance of SSH going and perform debugging from another process.
As for portability, it depends on what you are trying to do. If all you want is a simple console-based application, you shouldn't run into any major portability concerns. If you are using more complex code, portability depends heavily on two things. The first is the choice of libraries - sure, you can run applications written for Win32 on Linux with Wine or actually compile them with Winelib, but it's not a pleasant experience. If you choose something more portable like Qt or gtkmm, you'll have a much easier time of things. Likewise for filesystem code - using a library like Boost.Filesystem will make things significantly simpler. The second thing that makes a big difference for portability is to follow the documentation. It's hard to stress this enough - many things that you do incorrectly will have varied results on different platforms, especially if you are using libraries that don't do checks (note: I highly recommend checking code against debug standard libraries for this reason). I once spent nearly a weak tracking down a portability bug that arose because someone didn't read the docs and was passing an invalid parameter.
If you want to use remote desktop like facility try VNC www.realvnc.com
or in case its just a remote login Hummingbird, EXceed could help
You might want to check the wingdb visual studio extension.
Not sure if this will help, but take a peek at sshfs. I haven't had a need to use it myself, but I have read others use it to access remote files and directories via ssh and work on the files locally. I presume you could access your remote home directory via sshfs and then use your local tools to work on the source files. I would very interested in knowing if this works out, so please post back if you give it a shot.
I use No Machine NX, which gives you the entire desktop of the remote machine. It also has a Windows client. I work remotely from home on Fridays, so I'm using it right now. You'll have to install it on the remote machine, and then install a client on your Windows or Linux machine.
