Question

How do i retrieve the netstat -a data from my python script from a local server. I have tried subprocess.Popen(['ssh','server','pass','netstat','-a'],stdout=file1) but it does not work. Any advice?

Answer 1

You must have key based authorisation from the desired server where netstat is suppose to run.
In the absence on key based authorisation, the ssh command will return a prompt asking for password.

Below is the link for key based authorisation:

or

Once the keys are exchanged, the command mentioned in your question does not require any password and no prompt will occur when you run it.

subprocess.Popen(['ssh','server','netstat','-a'],stdout=file1)
