connection to ssh via Python-CodePudding

Ciao, I want to connect via ssh using python. I've tried this command: os.system("cmd /k root@ip) and it worked well. the problem is that after this a password is required and it is not clear to me which command shall I use. Furthermore I noticed that the os.system command stay "alive" and doesn't allow the code to go on the next step until the shell is not closed. Thanks for support.

CodePudding user response：

Have you tried using paramiko?

import paramiko

ssh_client = paramiko.SSHClient()
ssh_client .connect(server, username=username, password=password)
stdin, stdout, stderr = ssh_client.exec_command(command)

You can use pexpect's pxssh module to connect to ssh and run command:

from pexpect import pxssh
import getpass
try:
    ssh_cmd = pxssh.pxssh()
    hostname = raw_input('hostname: ')
    username = raw_input('username: ')
    password = getpass.getpass('password: ')
    ssh_cmd.login(hostname, username, password)
    ssh_cmd.sendline('df -hT')   # run a command(you can specify any command here)
    ssh_cmd.prompt()             # match the prompt
    print(ssh_cmd.before)        # print everything before the prompt
    ssh_cmd.logout()
except pxssh.ExceptionPxssh as e:
    print("SSH login Failed")
    print(e)

For more details you can refer pxssh documentation.
