怎么用堡垒机连接外网

import paramiko

# 堡垒机的IP地址和端口
jump_host = '192.168.1.1'
jump_port = 22

# 远程服务器的IP地址和端口
remote_host = '10.0.0.1'
remote_port = 22

# 用户名和密码
username = 'your_username'
password = 'your_password'

# 创建SSH客户端
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())

# 连接到堡垒机
ssh.connect(jump_host, port=jump_port, username=username, password=password)

# 创建一个代理通道
transport = ssh.get_transport()
dest_addr = (remote_host, remote_port)
local_addr = ('localhost', 10022)
channel = transport.open_channel("direct-tcpip", dest_addr, local_addr)

# 创建一个新的SSH客户端连接到远程服务器
remote_ssh = paramiko.SSHClient()
remote_ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
remote_ssh.connect('localhost', port=10022, username=username, password=password)

# 执行远程命令
stdin, stdout, stderr = remote_ssh.exec_command('ls -l')
print(stdout.read().decode())

# 关闭连接
remote_ssh.close()
ssh.close()
