How to perform different commands over ssh with Python?

The simplest way to use SSH using python is to use paramiko. You can install it using −

$ pip install paramiko

To use paramiko, ensure that you have correctly set up SSH keys(https://confluence.atlassian.com/bitbucketserver/creating-ssh-keys-776639788.html) on the host machine and when running the python script, these keys are accessible. Once that is done use the following code to connect to a remote server using ssh −

from paramiko import SSHClient
ssh = SSHClient()
ssh.load_system_host_keys()
ssh.connect('user@server:path')
ssh_stdin, ssh_stdout, ssh_stderr = ssh.exec_command('ls')
print(ssh_stdout) #print the output of ls command

You can use the exec_command function to run any command supported by the server you're connected to over ssh. Running the above code will give you the directory listing on the remote server.
