我想使用paramiko来远程控制bat文件，并获取文件输出。但它不起作用。
def ssh2(username, password, hostname):
if __name__ == '__main__':
paramiko.util.log_to_file('paramiko.log')
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(hostname = hostname, username = username, password = password)
cmd = './tmp/batch_ping_dce.bat'
stdin,stdout,stderr = ssh.exec_command(cmd,timeout = 10)
print stdout.read()
ssh.close()
Windows服务器已经安装了bat文件所在的ssh服务器。 paramiko.log是这样的：

那么我如何使用python来完成这项工作呢？
