我想通过SSH登录到Exchange Server并执行MML（人机语言）命令。我能够成功登录，但无法执行MML命令。
我的代码：
import paramiko
ssh = paramiko.SSHClient()
ssh.load_system_host_keys()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect('10.200.220.3', port=22, username='USER', password='SYSTEM')
stdin, stdout, stderr = ssh.exec_command("ZUSI;")
opt = stdout.readline()
opt = "".join(opt)
print(opt)
预期结果：
WORKING STATE AND RESTART HANDLING COMMAND <US_>
< ZUSI;
