使用nutch爬行时拒绝身份验证和连接错误

Question

根据Nutch教程

http://wiki.apache.org/nutch/httpauthenticationschemes#a_note_on_ntlm_domains

>

我已经在httpclient-auth.xml文件中设置了auth-configuration：

http.auth.file httpclient-auth.xml“protocol-httpclient”插件的身份验证配置文件。

但对我来说没有成功！

是我没有以正确的方式配置身份验证还是我遗漏了什么？

我不支持任何代理，我已经关闭了系统中所有的防火墙设置。不知道为什么我会被拒绝连接异常。

在这里，我也无法找到确切的原因，为什么我得到连接拒绝异常。

请帮我理解一下这个情况下的确切问题。

logpart2-connection被拒绝。

1）从日志中可以清楚地看出NTLM在特定站点上的身份验证失败。

在这里，您必须首先检查用户名/密码。

然后是Auth basic/ntlm/的方案，然后是要在其上进行authicated的端口
