So I have an SSH session to a windows XP box via WinSSHD (from Ubuntu). I coded up a small Python program to take a screenshot with pywin32. Everything works fine when I run the script on the XP box directly in a normal 'desktop' session but if I SSH in and run the script the script fails:
Traceback (most recent call last):
File "ss.py", line 38, in <module>
win32_ss()
File "ss.py", line 19, in win32_ss
cDC.BitBlt((0, 0),(w, h) , dcObj, (0, 0), win32con.SRCCOPY)
win32ui.error: BitBlt failed
I am assuming this is because the SSH session is a different session than the XP session and has no access to the 'desktop' display device. I found reference on how to do this (I think this is what I want to do) in linux:
DISPLAY=:0.0 import -window root /tmp/shot.png
I suppose what I'm looking for is how to do this in windows. Again, I'm using Python and can install any module needed. I currently am using pywin32 as this is much faster than PIL.
I think SSH is the problem. I am not sure if SSH is the best way to do this. The best way would be to do the screenshot work at Windows' end. I have done something similar recently. I wanted to take a screenshot of a webpage opened in Internet Explorer and I am using Selenium Webdriver for this purpose with Python bindings for it.
What I did was that I decided to do it with the help of TCP sockets. I just wrote a very simple Python script that opens a TCP socket on the Windows machine and listens for connections. As soon as it receives the connection, it does the work of taking the screenshot. So in your case, it can take the screenshot there and save it locally and then the script can SSH to the system where you want this file to be.
Hope this helps.

I want to automate a very old software (drafix) that can only be run in Windows XP, on a remote desktop.
Would it be possible to write a pywinauto script that would directly interact with the software controls, without the need to send mouse/keyboard clicks on the GUI, and then minimize the Remote Desktop screen or even lock the PC?
I need to open the program, loop through a list of file names, open each one of them and save as a different format.
I did it with some basic GUI automation - clicking on buttons if necessary, sending keyboard shortcuts and entering the file names form a list. But it isn't very reliable, and I would like to minimize the Remote Desktop window and use my PC instead of having it in the foreground.
From what I have read here, it should be possible with some workarounds, and I would need to install an older version of Python (any idea which one?) on the remote desktop to write and run the script there.
What you can do is just copying your script to remote machine and run it there. Regarding minimized or closed RDP there are few workarounds and tricks described in the Remote Execution Guide which summarizes few StackOverflow answers.
There is other way that you can control gui application on remote Desktop with pywinauto. You can use rpyc or Remote Python Call. that is a python library for rpc(remote procedure call)
https://rpyc.readthedocs.io/en/latest/
your remote computer is as server and your host is as client in rpyc.
first you you need to run rpyc_classic.py in remote computer after connect to it and use pywinauto library. for example i use rpyc for start microsip on remote computer with pywinauto.
ip of remote computer is 192.168.222.222.
import rpyc
ip = "192.168.222.222"
conn = rpyc.classic.connect(ip)
conn.execute("from pywinauto import Application")
conn.execute(r"Application().start(r'C:\Program Files (x86)\MicroSIP\microsip.exe')")
So there are variants of this question - but none quite hit the nail on the head.
I want to run spyder and do interactive analysis on a server. I have two servers , neither have spyder. They both have python (linux server) but I dont have sudo rights to install packages I need.
In short the use case is: open spyder on local machine. Do something (need help here) to use the servers computation power , and then return results to local machine.
Update:
I have updated python with my packages on one server. Now to figure out the kernel name and link to spyder.
Leaving previous version of question up, as that is still useful.
The docker process is a little intimidating as does paramiko. What are my options?
(Spyder maintainer here) What you need to do is to create an Spyder kernel in your remote server and connect through SSH to it. That's the only facility we provide to do what you want.
You can find the precise instructions to do that in our docs.
I did a long search for something like this in my past job, when we wanted to quickly iterate on code which had to run across many workers in a cluster. All the commercial and open source task-queue projects that I found were based on running fixed code with arbitrary inputs, rather than running arbitrary code.
I'd also be interested to see if there's something out there that I missed. But in my case, I ended up building my own solution (unfortunately not open source).
My solution was:
1) I made a Redis queue where each task consisted of a zip file with a bash setup script (for pip installs, etc), a "payload" Python script to run, and a pickle file with input data.
2) The "payload" Python script would read in the pickle file or other files contained in the zip file. It would output a file named output.zip.
3) The task worker was a Python script (running on the remote machine, listening to the Redis queue) that would would unzip the file, run the bash setup script, then run the Python script. When the script exited, the worker would upload output.zip.
There were various optimizations, like the worker wouldn't run the same bash setup script twice in a row (it remembered the SHA1 hash of the most recent setup script). So, anyway, in the worst case you could do that. It was a week or two of work to setup.
Edit:
A second (much more manual) option, if you just need to run on one remote machine, is to use sshfs to mount the remote filesystem locally, so you can quickly edit the files in Spyder. Then keep an ssh window open to the remote machine, and run Python from the command line to test-run the scripts on that machine. (That's my standard setup for developing Raspberry Pi programs.)
I have a sikuli script which does the Siebel Tools incremental Compilation Task on a Windows Box from Jenkins.
The problem is: When i run the task i always have to open the RDC window open for the task to be executed.As soon i minimize the window the script fails.
Hence if the Sikuli script is running i will not able to use my local system for any other task.
I found some posts on launchpad.net.
this is one reference: https://answers.launchpad.net/sikuli/+question/213636
But it did not work.
Can anyone help on this.
This solution has helped me out:
Close all open Remote Desktop sessions.
Launch the Registry editor (regedit.exe).
Navigate to one of the following Registry keys, depending on whether you wish to modify the Remote Desktop settings only for the current user or for all users on the computer:
HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client
HKEY_LOCAL_MACHINE\Software\Microsoft\Terminal Server Client
Create a DWORD value named RemoteDesktop_SuppressWhenMinimized and set it to 2.
Close the Registry Editor.
After these steps are done RDC when minimized will not be suppressed and sikuli will work.

Other solution is to use VNC connection instead of RDC. RealVNC for example.
You setup VNC server on machine that sikuli scripts are running on and connect from your other machine. You should even be able to close the connection window and scripts should still be able to run.
You could just keep the RDC session running in the background. Just don't minimize it. I am doing the same with my tests.
I have the following situation.
I want to write python code in my Laptop that will take more than 24 hours to run.I am using UBUNTU 12.04 lts.
Is it possible so that I write python code in my laptop, automatically send it to some remote desktop, run there and send the output result to my laptop when done?
one way suggested to me is to use openssh.
But I want to do this in the following way----
Write and Debug Python Code in my laptop.(Solved)
email the code as attachment to ****#gmail.com(Solved)
Other python program in the desktop will automatically download and run the source code(Unsolved)
and email the output file back to my gmail id.(Solved)
what is the python code to download the attachment from the latest email from a specific gmail folder?
If your remote system is windows, a good option would be to use PsExec from SysInternals.
Ex. If your script is long_running.py a typical usage would be
PsExec \\remote-server -c long_running.py
If your remote system is *nix, and your local system is Windows, you can use ssh for remote execution via Plink (part of PuTTY).
plink remote-server#user -m long_running.py
Finally if both remote and local machine are *nix systems, you can simply use ssh
ssh remote-server#user 'bash -s' < long_running.py
Note This is just some possible options, but the idea is remote execution is possible either via ssh or a similar option (like PsExec) for Windows
If both systems are running *nix, you can easily do all your dev work and debugging locally, while still executing remotely:
One time set up:
Mount a folder from the remote box locally
On your laptop, save your project/script to that (now local) folder, or set the mounted folder as your project's save path in your IDE.
Publishing:
Do work
Click the save button
Executing:
SSH into the remote box and open a new screen
Navigate to the folder you'd previously mounted, and run your script.
You can then safely detach and close ssh if necessary (ctrl+a d), and re-attach later:
3a. screen -ls (to find the screen name)
3b. screen -x screen_name
The advantage of this solution is that if you've got an ongoing project requiring frequent edits/changes, you can do all your dev work/debugging locally, and the only work required to "publish" is clicking the save button, starting the screen, and running.
I set up a job that want to execute an action that open the local browser. I write it use the python script:
import webbrowser
if __name__=="__main__":
webbrowser.open("http://www.example.com")
Then,i click Build now button on jenkins dashboard, it can execute successful and show successful as a result at last. But nothing happen for browser.It's very wierd that other python script could execute correctly, I have no idea why?
Addition:This jenkins(Jenkins ver. 1.524) is installed on my laptop and my laptop's OS is Win7, i start jenkins as a Windows Service. Do u have any idea?
If you are running Jenkins as a Windows service, by default it runs as user Local System. Did you check the box titled "Allow service to interact with desktop"?. If that does not help you may have to set the service to log on as an actual user, instead of Local System. This is a common problem with running any process with a GUI from Jenkins.
