ftp 備份配置，save保存配置

paramiko，re

例子

ssh = paramiko.SSHClient()    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    try:
        ssh.connect(

            timeout=3, allow_agent=False)

        time.sleep(0.1) # 設置間隔


        for cmdline in cmdlist:

        time.sleep(1)


        remote_conn.send('save\n')  #保存設備當前配置
        time.sleep(0.5)
        save = remote_conn.recv(1000).decode()
        if save.find('written') > -1:
