Dns 易得易失Debian

我有一台运行Debian Squence的Linux服务器，我不能在上面运行

apt get update

。我会遇到如下错误：

W: Failed to fetch http://ftp.us.debian.org/debian/dists/squeeze/main/binary-i386/Packages.gz
Unable to connect to 10.197.3.5:3142:

我可以成功地

ping ftp.us.debian.org

，但是它显示的ip地址与无法连接消息显示的ip地址不同

我认为这是DNS翻译的问题，所以我把我的DNS服务器改成了google的8.8.8.8服务器 运行

dig google.com

显示DNS服务器实际上是我指定的google服务器。

我被难住了。可能需要注意的是，我正在将端口22和端口80转发到我的路由器，以便我的队友可以

ssh

并查看与此服务器关联的网页。我不认为这是问题，因为即使我停止转发，也会发生这种情况

原来这台服务器的原始持有者在/etc/apt/apt.conf中设置了一个不起作用的代理（我不知道为什么会这样） 我从那个文件中删除这一行

Acquire:：http:：PROXYIP/apt cacher/”代理

我已经修复了类似的问题，并对您的问题发表了评论：

我认为您的

sourcs可能有问题。请列出
并共享您正在使用的版本。是否定义了代理？如果conf文件不存在，则可能位于
/etc/apt/conf
或
/etc/apt/apt.conf.d/70debconf
中。这是代理问题！这个服务器是由另一家公司设置的，我不知道他们设置了代理
