我尝试在 Ubuntu 9.10 上设置与 ItsHidden 的 VPN 连接。我在 VPN 配置中仔细检查了我的凭据，但我认为这不是问题。在我的系统日志中，我收到了以下消息：

由于 gethostbyname 失败，我猜想 NetworkManager 不知道我使用代理访问互联网。我不确定这是否是真正的问题。
您能告诉我一个让 gesthostbyname 不再失败的解决方案吗？
答案1
使用代理不会影响您执行 DNS 查找的能力。尝试运行nslookup vpn.itshidden.com以检查这一点。您需要理清执行 DNS 查找的能力（请参阅 /etc/resolv.conf）或将 vpn.itshidden.com 添加到 /etc/hosts 并希望 IP 地址不会改变，或者只是在您的 VPN 设置中使用 vpn.itshidden.com 的 IP 地址。
