Struggling to connect to server with Python

I have a Red Hat Linux Server and I am trying to connect to it with Python but I kept getting "ConnectionRefusedError: [Errno 61] Connection refused". I have tried to connect to it with simply connecting to the ip address and port number but I am getting the same thing. I have even tried connecting to it with a socket but still I get the same thing. I am currently using the paramiko library to connect to it but still I am getting the same thing. I am using a rsa key to connect to it but I am still getting the same error. I am simply trying to connect to the server because I want to run a batch file on it simply by sending a command from my python code. I have used the pxssh library but it is giving me "PasswordAuthentication is false for this host" which I don't understand because all my parameters are set to true. Any help would be appreciated. This is my code using paramiko to connect to it: ```python import paramiko import socket def connect_to_server(ip_address, port_number, rsa_key, rsa_password, username): try: ssh_client = paramiko.SSHClient() ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh_client.connect(ip_address, port_number, username=username, key_filename=rsa_key, passphrase=rsa_password, look_for_keys=True) print("Connected to the server") except paramiko.AuthenticationException as e: print(f"Authentication failed: {e}") return False except paramiko.SSHException as e: print(f"Connection failed: {e}") return False except paramiko.BadAuthenticationType as e: print(f"Bad authentication type: {e}") return False except Exception as e: print(f"Any other exception: {e}") return False return ssh_client ip_address = "192.168.2.29" port_number = 8080 rsa_key = "/Users/yourusername/.ssh/your_private_key" rsa_password = "your_key_password" username = "your_username" ssh_client = connect_to_server(ip_address, port_number, rsa_key, rsa_password, username) if ssh_client: stdin, stdout, stderr = ssh_client.exec_command('ls -l', get_pty=True) for line in stdout: print('... ' + line.strip()) ssh_client.close() ``` This is my code using the pxssh library: ```python import pxssh def connect_to_server(ip_address, username, password): try: ssh_client = pxssh.pxssh() ssh_client.login(ip_address, username, password, auto_prompt=True) return ssh_client except pxssh.ExceptionPxssh as e: print(e) return False ip_address = "192.168.2.29" username = "your_username" password = "your_password" ssh_client = connect_to_server(ip_address, username, password) if ssh_client: ssh_client.sendline('ls -l') ssh_client.prompt() print(ssh_client.before) ssh_client.logout() ``` This is my code using socket: ```python import socket def connect_to_server(ip_address, port_number): try: ssh_client = socket.socket(socket.AF_INET, socket.SOCK_STREAM) ssh_client.connect((ip_address, port_number)) return ssh_client except socket.error as e: print(f"Connection failed: {e}") return False ip_address = "192.168.2.29" port_number = 8080 ssh_client = connect_to_server(ip_address, port_number) if ssh_client: ssh_client.sendall(b'ls -l') data = ssh_client.recv(1024) print(data.decode()) ssh_client.close() ``` This is my code using socket with rsa key: ```python import socket import paramiko def connect_to_server(ip_address, port_number, rsa_key, rsa_password, username): try: ssh_client = socket.socket(socket.AF_INET, socket.SOCK_STREAM) ssh_client.connect((ip_address, port_number)) except socket.error as e: print(f"Connection failed: {e}") return False try: ssh_client = paramiko.SSHClient() ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh_client.connect(ip_address, port_number, username=username, key_filename=rsa_key, passphrase=rsa_password, look_for_keys=True) print("Connected to the server") except paramiko.AuthenticationException as e: print(f"Authentication failed: {e}") return False except paramiko.SSHException as e: print(f"Connection failed: {e}") return False except paramiko.BadAuthenticationType as e: print(f"Bad authentication type: {e}") return False except Exception as e: print(f"Any other exception: {e}") return False return ssh_client ip_address = "192.168.2.29" port_number = 8080 rsa_key = "/Users/yourusername/.ssh/your_private_key" rsa_password = "your_key_password" username = "your_username" ssh_client = connect_to_server(ip_address, port_number, rsa_key, rsa_password, username) if ssh_client: stdin, stdout, stderr = ssh_client.exec_command('ls -l', get_pty=True) for line in stdout: print('... ' + line.strip()) ssh_client.close() ``` This is my code using socket with rsa key and pxssh: ```python import socket import pxssh import paramiko def connect_to_server(ip_address, port_number, rsa_key, rsa_password, username): try: ssh_client = socket.socket(socket.AF_INET, socket.SOCK_STREAM) ssh_client.connect((ip_address, port_number)) ssh_client = paramiko.SSHClient() ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy()) except socket.error as e: print(f"Connection failed: {e}") return False try: ssh_client.connect(ip_address, port_number, username=username, key_filename=rsa_key, passphrase=rsa_password, look_for_keys=True) print("Connected to the server") except paramiko.AuthenticationException as e: print(f"Authentication failed: {e}") return False except paramiko.SSHException as e: print(f"Connection failed: {e}") return False except paramiko.BadAuthenticationType as e: print(f"Bad authentication type: {e}") return False except Exception as e: print(f"Any other exception: {e}") return False ssh_client = pxssh.pxssh() ssh_client.login(ip_address, username, rsa_password, auto_prompt=True) return ssh_client ip_address = "192.168.2.29" port_number = 8080 rsa_key = "/Users/yourusername/.ssh/your_private_key" rsa_password = "your_key_password" username = "your_username" ssh_client = connect_to_server(ip_address, port_number, rsa_key, rsa_password, username) if ssh_client: ssh_client.sendline('ls -l') ssh_client.prompt() print(ssh_client.before) ssh_client.logout() ```
