I have a python script located on a remote server with SSH enabled. That script displays a lot of debug messages displayed while executing. I want to trigger this script using another python script which is on my local system and depending on the output of the earlier script, I want to proceed further. While doing all this, I want the display messages on the remote server to be displayed on my local system as well. Basically, I want to view whatever output is thrown by the remote script during the course of the script, on my local system. I am able to trigger the script using paramiko but I am neither able to check whether the script on the remote server is running nor am I able to view it's output. Is there any way to do it? Already tried conn.recv(65535) but to no avail.
In my experience I found python fabric module easier than using paramiko. If you want to execute local script on remote machine using fabric. You just need to upload them using put() and then call run() api.

I want to execute a Python script when creating an alarm (McAfee ESM Virtual machine - ESM 11.5.4 20220106). When creating an alarm, I configured "Execute remote command". Alarm is being triggered but script isn't getting executed. I tried as shown in the image below but it didn't work.
I found a way to this. You can't execute a script situated in the ESM (In the image above, the IP is of ESM machine itself). You have to spin another VM with the required ports open. Refer image in the question.. So, the IP address, credentials and script path has to be of the VM.
Basically you should have a command server for script execution and others.
Also, in my case I noted that only bash scripts were getting executed. Python scripts failed. So, the work around to that could be that you mention bash script in ESM and inside bash script you write a command to execute the python scripts that has to be executed.
Hope it helps!
Consider situation:
I have an Ubuntu server with installed Python, tensorflow and other libs.
My code is python script, that load several models, some of them pretrained vectors .bin, some files from server folders, etc.
When i run script in terminal it launch interactive session, where i input some text and script output me back (like chatbot). During answer it call my Ai models (Tensorflow, keras).
Question: how do i access this running session from other python script? I mean i want use it as a function: to send text and receive answer back.
And of course i need to run this terminal session in background for long time.
I read this and similar answers, but not sure is that right solution (seems not a full):
In Linux, how to prevent a background process from being stopped after closing SSH client
What i am asking, commonly is done by REST server with API that expose and then this api is called from a external code. But there is no API wotking: Tensorflow throw errors when run via Flask (was not able to fix).
If you want your script stays up after closing ssh session, add & disown at the end of your execution command and it will run in background.
I'm having troubles to run a python script in DigitalOcean.
I have two doubts.
How to upload the scripy.py to DigitalOcean droplet.
How to run the script.
I'm able to access to the console, but further that I don't know what to do and i can't find any specific information on internet.
I'm running a Ubuntu 14.4 Droplet through web.
Ok first, in order to upload any file to your droplet you can user the command scp
scp foobar.txt your_username#remotehost.edu:/some/remote/directory
Here is a related question that shows you how to use scp from Windows.
Then in the console setup in the remote host check if you can run the command python. If you do not have it, just follow the steps in the documentation and you will have python running inside your remote machine.
If you put a Python script on the server and ssh in, you can run it from the command line. For instance,
python yourFantasticScript.py
If you want a level of automation to triggering the script to run, you will need to learn more about automation scheduling and server technologies.
So I am trying to set up a Continuous integration environment using Jenkins.
One of the build step requires a series of mouse actions/movements to accomplish a task in Excel. I have already written a python script using the ctypes library to do this.
The script works perfectly fine if I run it either through Jenkins or on the server itself when I am actively logged in to the server using remote desktop connection, but as soon as I minimize/close the connection and then run the script from Jenkins, it seems the mouse events never get executed. Is there something I can add to the script to make this work? Thanks for any help you can provide.
I have been interested in finding an alternative to the UI in SAS for quite some time now. We license SAS on our server instead of our desktops, so furthermore we have to launch a remote desktop application to execute code.
I was able to use a Telnet connection instead to remotely connect to the server, and batch execute SAS programs. Then I was interested in whether a python script could be made to connect remotely, and batch execute code, and this script could be executed in jEdit as a BeanShell script.
So far, I have Python code which successfully opens and closes the Telnet connection. It can do basic shell functions like call "dir". However, when I pass the exact same line that I use to execute SAS from command prompt on the remote server with a telnet connection in Python, nothing happens.
Is it possible the server is preventing me from executing code from a script? I use a "read_until" statement for the prompt before running any code.
Here's a few ideas...
The issue you are having above may be related to Local Security Policy settings in Windows (if it is running on a windows server). I'm far from an expert on that stuff but I remember older SAS/Intranet installations required some rumaging around in there to get them working.
As an alternative to the approach you are trying above you could also setup a SAS session on the server that listens for incoming socket requests as per this article:
http://analytics.ncsu.edu/sesug/2000/p-1003.pdf
And finally... Not sure if this helps or not by I remotely execute SAS jobs using PSEXEC. A description of how I set it all up can be found here:
http://www.runsubmit.com/questions/260/hide-sas-batch-jobs-winxp
Good luck
This paper outlines how you can use a Python script to connect to a Unix server using SSH, copy the SAS program written locally onto the server, batch submit it, and download the results back to your local machine, all using a BeanShell macro script for jEdit.
