I am wondering if it is possible to connect to a git server that is hosted on another server (running Linux) through a C# ASP.NET application. I am only looking for reading capabilities to be able to display information of that git repository in the ASP.NET application.
SharpSSH is really easy to use and i've never had any problems with it, it will let you connect via SSH and run commands, or use SCP to copy files from the server.
I would simply stream the output that a local msysgit command would return.

I'm trying to upload a .net console application, which has selenium in it which does some automation in the web.
I have seen the docs that tell us how to upload a mvc application and i have hosted it successfully.
So the question is, is it possible to upload a console application created in visual studio to aws.
Amazon EC2 creates a virtual machine that runs the operating system of your choice.
You can run whatever you wish on it, as long as it does not violate the Terms & Conditions of usage.
you can deploy it to AWS Lightsail or AWS EC2 . But you are in developing some application, it is better to deploy to AWS Lightsail as to reduce cost of development.
Of course Possible it will be very easy, I hope. In my case I use .NetCore 3.1 console app, where I implement tcplistener, tcpClient.
Configure port in aws.
when u create instances u will see public ipv4 address, that u will put in yours
client or app file.
and after than in that instance open cmd -> type ipconfig -> thane u find private
ipv4 address, that use in server file.
Finished!!!
Literally you don't need AWS to host your console app at all, as you can write even simpler AWS Lambda in C#, which is similar to Azure Functions.
I need to create a C# client with .NET Framework 4.6.2 to connect a server.
My client offers me the possibility to connect to a SFTP server or to a FTPS server, but I don't know which one is the best to connect with.
On this page, I have found this:
No built-in SSH/SFTP support in VCL and .NET frameworks
I need to connect to a server to upload and download files. I also need to monitor a directory on the server to know when a file is on that remote directory.
Searching on Internet I'm not sure if the .NET libraries (SSHNet) that implements SFTP protocol are good enough to a production environment.
I think SFTP is the best option to use but FTPS could be easier to implement a C# client for it.
Or maybe I can use libssh2 to implement a C program that do the job to monitor a remote directory, download any new file on it and upload the files that I need to upload.
Any advice?
If both protocols are fine for your actual needs (as suggested in your question and comments), if it's only a matter of "what's the easiest to use in .Net", I would simply go for FTPS.
It's very fast to implement, since you'll find all what you need in the framework ("FtpWebRequest" class, or more recently "WebClient", etc), even on old versions of the framework.
You can find plenty resource about this on the web or on SO
You have mentioned that you need to "monitor" a folder on remote server. Of course there's no problem with FTPS to retrieve the list of all files of a folder, but it will be in "pull" mode, as frequently as you wish. There's no way for the server itself to push you a notification every time a new file has been dropped. So if you need some real-time notifications, it's not optimal.
I'm using SshClient from Renci.SshNet and i have noticed that all the commands are not effective on the remote server.
For example, that one works fine :
mySSH.RunCommand( "touch test");
will create a file on the remote server.
but this one won't do anything :
mySSH.RunCommand( "nohup dnx web &");
I searched all over the internet and i'm so disapointed cause nobody talk about that.
Mostly, all commands that are simple like create a file or a folder, but strong commands like executing a script or starting my application (the most important) just simply don't want to do anything.
Thank you in advance.
Can you run this command when you log in over ssh as the same user Ssh.Net is using?
I am planning to do an App either in c++/C# (through Visual Studio) in Windows 7.
OK what this app does is it will accept input through studio elements like text box or buttons ..then it should create an command based on input and run these command on the Linux server.
E.g : One simple example is to restart a certain process on a Linux machine
Now to proceed to my problem:
How do I connect my App to Linux machine?
I don't want to install any third party application as i am not allowed to do so.
If possible please list me the different ways i can do this
Well, you can do this. I am already familiar with this scenario. I have several application setup working this way. The only option that will allow you to do this without any 3rd party application is using SSH protocol.
The SSH protocol is the well known and most power full tool of linux sysadmins. You can execute any command over it on a linux box from any part of the world or any piece of shit which can run an SSH client. Ask me on comment if you need more info on this.
EDIT
One example, if you want to restart certain process.. You can pass the command over SSH as below.
ssh user#server_ip '/etc/init.d/httpd restart"
The above will restart the HTTPD(Apache) service.
Some libraries you can use in .NET
http://www.codeproject.com/Articles/11966/sharpSsh-A-Secure-Shell-SSH-library-for-NET
https://sshnet.codeplex.com/
I have not used above libraries in .Net, Instead I have done several things using linux box with python and bash.
if I understand correctly, to solve this you can implemente WebService.
But when you said :
I dont want to install any third party application as i am not allowed
to do so
I'm afraid you can not setup WebService on Linux server ?
Other possibility, use SSH if already install on linux server (some chance that is) and you probably could find a .Net lib to make SSH
This link will help .Net class to execute remotely on Linux over SSH?
I have done plenty of C# shell command calls, apps, batch files etc. The other day I was asked if it would be a problem if an executable that I currently run from my web site app, would move to another server on our intranet.
In other words the web site app and the executable that I am running through Process.Start(...) are located on the same box currently - all good there. Now there is a wish to separate the two on two different servers.
I done a few futile attempts to execute an app (located on server B) from server A (where the web site resides).
Is there a way that I have not run cross yet to do this ?
Thanks
PsExec is one way with minimal coding. Using System.Diagnostic.Process, you can call this command:
psexec \\ServerB (path)\myapp.exe arg0 arg1 ...
To control the processes of server A by running an application on server B, you would need an application running on server B that would get controlled remotely somehow.
As an example, let's say server A runs unix, so you could write a application that would connect to server A using ssh, authenticate and then control the processes and whatnot like you do in a shell. If server A does not allow ssh connection, you could write your own application that would be running on server A listening to some connection and commands that would come from an application in server B.
It's quite hard to understand what are your current settings and why would you even want to switch the application from server A to server B, so a little more information would wield you a better answer.
Austin's PSExec approach is probably the easiest approach to executing an EXE on a remote machine, but you may want to consider a potentially more robust solution:
You could modify your command-line app to run as a service and to respond to requests for work and/or data via a WCF (binaryXML/TCP or XML/HTTP) call.
