如何检索命令telnet python的结果

Question

这是我的telnetlib代码：

HOST = "@ip"
user = "Hichem"
password = "Hichem"
tn = telnetlib.Telnet(HOST)
tn.read_until("Connexion : ")
tn.write(user+ '\r\n')
if password:
    tn.read_until("Mot de passe de Hichem : ")
    tn.write(password+ '\r\n')

好。我成功访问了服务器。

我想在文件中获取命令的结果（Restrictions.txt）。

结果是：

(Number of results = 1)

(Number of results = 1)

那是我的代码：

fichier= open ("Restrictions.txt", "w")
while True:
      lign = tn.read_until(b"\n\r")
      #print lign
      fichier.write(lign)

fichier.close()

程序被阻止。

提前谢谢。
