如下，以建立系統使用者舉例，

配置檔案配置普通使用者資訊，登入後切換root使用者，建立一個指定名字和密碼的系統使用者:

def create_user(root_pwd,username,password):
    import paramiko
    result = []
    ssh = paramiko.SSHClient()
    #把要連線的機器新增到known_hosts檔案中
    ssh.load_system_host_keys()
    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    ssh.connect(
             hostname = settings.HOST,
             port = settings.PORT,
             username = settings.USERNAME,
             password = settings.PASSWORD,
             timeout  = 60,
          )
    sc = ssh.invoke_shell()

    def exe_cmd(cmd,t=0.1):
        sc.send(cmd)
        sc.send("\n")
        time.sleep(t)
        resp = sc.recv(9999).decode("utf8")
        #print "cmd='%s',echo='%s'\n"%(cmd,resp)
        return resp
    
    #切換root賬號
    resp = exe_cmd("su root",t=1)
    if resp.endswith(u"密碼："):
        resp = exe_cmd(root_pwd)
    
    #建立使用者
    cmd_create_user = "useradd {username} -d /home/{username}".format(
        username = username,
    )
    exe_cmd(cmd_create_user)

    #修改密碼
    cmd_change_user_pwd = """echo "{password}" | passwd --stdin {username}""".format(
        username = username,
        password = password,
    )
    exe_cmd(cmd_change_user_pwd)
