python - sshuttle 无法使用 --DNS 路由启动

Question

我已成功运行到同一台计算机的隧道，但无法使用 --dns 加载 sshuttle。没有它，它会加载并运行。这是命令行和控制台返回...有什么想法吗？

无论我做什么，我都无法让这个坏男孩在启用 --dns 的情况下启动。

$ sshuttle --dns -vr server:8080 0/0

谢谢!

根据我上面的评论，事实证明该错误与 resolv.conf 中的 dnsserver 有关。我不确定将其更改为像 google 或 safeDNS 这样的自定义 DNS 服务器是否是一件坏事，但我做到了，而且现在它正在按预期工作。似乎 resolvconf 程序中的路由存在问题，在这里发现，一个人做了与我类似的事情来解决，但评论者指出了一个更深层次的问题，但没有详细说明如何解决:http://opensourcemissions.wordpress.com/2012/12/03/sshuttle-dns-stopped-working-and-how-i-fixed-it/
