In this article, we will show you how to automate SSH login in script using Python. We will also show you how to securely connect to your server using SSH key-based authentication.
Python is a powerful programming language that can be used for automating tasks. SSH is a secure protocol that can be used to connect to remote servers. By combining these two technologies, you can automate many tasks, including SSH login.
There are many ways to automate SSH login in script using Python. In this article, we will show you two methods. The first method is using the Paramiko module. The second method is using the pexpect module.
The Paramiko module is a popular module that can be used to connect to remote servers over SSH. Paramiko is easy to use and supports many features.
To install Paramiko, you can use the pip command.
pip install paramiko
The Paramiko module can be used to connect to remote servers and execute commands. In the following example, we will connect to a remote server and execute the ls command.
import paramiko
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(‘192.168.1.1’, 22, ‘user’, ‘password’)
stdin, stdout, stderr = ssh.exec_command(‘ls’)
print stdout.read()
ssh.close()
In the above example, we imported the paramiko module. We then created an SSHClient object. We set the missing host key policy to AutoAddPolicy. This will automatically add the host key if it is not found in the known hosts file.
We then connected to the remote server using the connect() method. We passed in the hostname, port, username, and password.
We then executed the ls command using the exec_command() method. We stored the output in the stdout variable. We then printed the output.
Finally, we closed the SSH connection using the close() method.
The Paramiko module is a powerful module that can be used to automate SSH login in script using Python.
The pexpect module is another popular module that can be used to automate SSH login in script using Python. Pexpect is easy to use and supports many features.
To install Pexpect, you can use the pip command.
pip install pexpect
The Pexpect module can be used to connect to remote servers and execute commands. In the following example, we will connect to a remote server and execute the ls command.
import pexpect
child = pexpect.spawn(‘ssh user@192.168.1.1’)
child.expect(‘password:
