问题描述

但是如果我使用wget，或者在具有Chrome或Firefox的Ubuntu桌面下，我可以访问该页面。

But if I using wget, or under Ubuntu desktop with Chrome or Firefox, I can't get any things.

就像这样：

root@ubuntu:~# wget 121.199.111.177
--07:57:52--  http://121.199.111.177/
            => `index.html.1'
Connecting to 121.199.111.177:80... connected.
HTTP request sent, awaiting response... Read error (Connection reset by peer) in headers.
Retrying.

我尝试使用用户代理，但仍然无法正常工作：

I tried using user-agent, but still not work:

root@ubuntu:~# wget --user-agent="Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)" http://121.199.111.177/
--08:08:04--  http://121.199.111.177/
           => `index.html.1'
Connecting to 121.199.111.177:80... connected.
HTTP request sent, awaiting response... Read error (Connection reset by peer) in headers.
Retrying.

为什么？如何使用wget来获取此页面？

Why? How can I get this page use wget?

推荐答案

错误代码500是服务器内部错误。 Wget会在标题中读取此错误代码，甚至不用费心去获取内容。因此，服务器需要解决一个问题。

Error code 500 is an internal server error. Wget reads this error code in the headers and doesn't even bother getting the contents. So there's a problem with the server that needs to be fixed.

$ wget -S http://121.199.111.177/
--2010-12-05 02:18:32--  http://121.199.111.177/
Connecting to 121.199.111.177:80... connected.
HTTP request sent, awaiting response...

某些telnet调试符合上述要求：

Some telnet debugging agrees with the above:

$ telnet 121.199.111.177 80
Trying 121.199.111.177...
