I have an application running only on Windows and a batch file that launches it.
I want to invoke this batch file from Linux, meaning something like Linux batch will launch the windows batch with parameters and this in its turn run my application.
Can I do that? How?
You could install an ssh server in the windows box (Cygwin has one), then from linux do something like:
ssh user#windows-box c:/path/to/batch.cmd
and that should launch your application in the windows box.
The most direct way is probably to install an ssh server on the windows box. Cygwin includes an ssh server.
Depending on how precise your timing needs are, you might be able to have an "at" job on the windows box that runs periodically (every 5 minutes?) and runs if it sees that a particular file exists, deleting the file. Then you could use Samba/smbclient to create the file. You would need to turn on filesharing on the windows box for this to work.
If the windows box has a web server, you could write a CGI, and trigger it using wget or cURL.
Our build process currently goes the other way: a windows sever kicks off things on the Linux server using plink (part of PuTTY). You might be able to set something similar up.
This may cause a security issue. Our information security person did not allow me to invoke any programs directly.
The safer way is to set up server on Windows computer. This can be a web-server for example. And then invoke your process inside PHP/Perl/Python script.
Also look at winexe that allows you to execute windows commands/batch scripts without running ssh server.

I am using a RDC Connection from my mac to connect to an application (on windows box) in client network. Is that possible to write a script which does the following:
Open ur RDC. (i am using CoRD for this where my VM credentials are saved in .rdp files.
Login to VM with valid credentials from your .rdp file.
Open your app on that VM (for ex: IE explorer)
Following code in my shell script will connect me to my VM.(First two steps are working)
open rdp://[username[:password]#]hostname
How should I automate third step?
Is there any other way than shell script?
If you install Jenkins on your Mac, then install the Jenkins slave agent on the Windows machine, you can remotely run any command you like on the Windows box via the Jenkins web UI, and get back the results as well. In that scenario there's no need to use RDC at all.
For some more background, see: https://wiki.jenkins-ci.org/display/JENKINS/Distributed+builds
This might be a simplistic answer, but AutoHotKey is something that will automate your 3rd step. Its free and pretty easy to script. You can have this in your start up routine for your VM, so when you log in, you can have this kick off your job.
I have used it before for testing some Java Swing components on Windows and its been pretty handy (Windows was running on a Virtualbox VM on my Mac).
I'm trying to execute a .bat file on a windows box remotely from a Linux box by connecting via ssh, obtaining windows command prompt and then executing the batch file.
When I connect to the windows machine I can see that the process is running but the graphical interface is not being invoked.

Probably, you need to install x server on windows? Consider for xming as one option. I am assuming that you have installed ssh-server on windows system.
NOTE: You need to login on the windows box (once, after windows login), start the x server on windows & then onwards you should be able to ssh to the system & start the GUI application.
Another possible issue:
The ssh-server binary should be executed by the user, after logging in once after the windows system boot. Then ssh to that windows box, export DISPLAY=:0 & run GUI app.
NOTE: I have not tested any of the above 2 solution, but these are what I think as possible solutions.
One more solution:
Create a dedicated TCP based server (on windows) client (on linux) model & send commands over that channel. A dirty way & would be able to give limited functionality, but it is tested to be working.
Currently, I want a remote machine (Amazon EC2 instance) to run a batch file when the machine starts up, and the batch file will close the machine after finishing the tasks.
I tried to put the shortcut of batch file to the startup folder. However, it will be only ran when I use Remote Control Connection to Log in that machine.
So, any other way to solve this problem???
NOTE: I don't want to log in to that machine since there might be 10 remote machines running at the same time.
Any idea or thought is appreciated. Thanks a lot.
This looks a bit like the question Running Batch File in background when windows boots up, my answer there:
You can use autoexnt for this. It was original designed for windows NT, but is still working in newer versions of windows.
You have to download the Windows 2003 Resource Kit to get it.
Windows XP (I believe Vista and 7 its the same as well, not sure about NT/2000)
Run gpedit.msc
Local Computer Policy -> Computer Configuration -> Windows Settings -> Scripts (Startup/Shutdown)
Open Startup. Click Add... Script Name: is where you input or Browse the location of your batch script to run. Script Parameters you can leave blank if you have no additional parameters you wish to pass w/it.
I have a windows server 2003 up in the internet.
But sometime I need to restart it.
After restart, I want one of the applications to run.
I want to do this all programatically.
I can now remotely restart the server.
But the question is how can I ask that piece of software to be executed (more precisely, I want to execute a .BAT file to ask a tomcat to run)?
Because I don't want to manually log in to the machine and start that application. That is time consuming. Is there any possible way, once the machine is started, my application will be run as well?
If you're developing an application that should always be running on the server, you probably need to implement it as a Windows service. For C#, see the classes in the System.ServiceProcess namespace -- you will need to inherit from ServiceBase.
Alternatively, you can set the program to be run as a scheduled task on boot. See the Task Scheduler API to do this.
You can install Cygwin and then do it the same way we'd do it on a Linux box: via ssh, using keys.
OpenSSH is not part of the default Cygwin install, so be sure to select it. It's in the Net category.
Then, after you've installed Cygwin and sshd, read /usr/share/doc/Cygwin/openssh.README to learn how to set up sshd as a service, so it will answer requests automatically, without you having to start the ssh daemon manually.
Finally, set up keys, as described in the link above.
Part of the ssh protocol is a way to ask a remote machine to launch a program. Setting it up with keys lets you do it without needing a password.
You could try xCmd, which is a freeware app to run a command on a remote machine.
My interactive 32-bit Windows app (now moving from Delphi [Ent] 2007 to 2009) uses command-line interactions to spawn child processes that do computationally-intensive tasks, which in turn write text files that the GUI parent app parses and analyzes - resulting in an interactive graphical display of the results.
I have access to a multiprocessor (multi-user) Linux cluster (via ssh), and would like to off-load the heavy lifting to that cluster. My question is how to spawn the processes in Linux from my Windows app. I can envision using secure FTP to put and get files, but not sure how to spawn the child processes in Linux.
Some leads for further reading would be fine - but code/pseudocode would be ideal. I can imagine that this may be more about Windows-Linux interaction than Delphi.
if you have access to ssh, one option is to issue commands through that.
For example:
ssh user#host ls -l ~
will in the ssh terminal show the files in the user's home directory. I'm not sure if this is what you really want. But it would likely work.
If you do this, you almost certainly want to setup SSH password less logins
However, A more ideal solution would likely be to setup a daemon on the linux boxes whose sole job is to run specific long running tasks in the background and let you fetch the results later.
You're going to have to install something on the Linux machine to run the process. You might find some kind of clustering or batch job submission API you can install and access from Windows. You might have to code a custom server. You might be able to run everything over ssh if you can drive an ssh process from Windows and if you have sshd installed on the Linux side. But my preference would be to write a webservice or simple CGI script on the Linux side designed to take your arguments and data and return the result over plain old http (or https as the case might be).
One way or another, this is going to encompass more than just coding on the Windows side.
I would download the full "putty" package.
As well as the excellent secure shell terminal, it includes PSCP to transfer files securely and PLINK to remote execute commands over SSH.
Hint: you will need to set up the full public/private key configuration for PLINK to work without an annoying password prompt. There is a useful guide http://unixwiz.net/techtips/putty-openssh.html>here.
