名称或服务未知 [英] Name or service not known

问题描述

我一直在尝试使用以下代码获取登录计算机的用户的ipaddress，但出现错误。

I have been trying to get the ipaddress of the person who logged into the machine using the below code but I get a error.

>>> import socket
>>> socket.gethostbyname_ex(socket.gethostname())
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
socket.gaierror: [Errno -2] Name or service not known

相同的代码在其他Linux盒中工作。
不知道我要解决此问题。

The same code works in other linux box. Not sure I fix it.

推荐答案

由于未正确设置主机名而发生了错误。在三个不同的位置设置主机名-

Error has occurred just because of not setting up hostname properly. Set the hostname at three different places, which are in -

1. / etc / hostname


2. / etc / hosts


3. 运行命令$ hostname

然后注销并再次登录。完成了。

then logout and login again. You are done.
