带有RNDIS系带电话的Ubuntu机不能接收来自因特网的数据包。

Question

我试着把我的旧Windows 6手机和我的Ubuntu电脑绑在一起使用手机的网络。然而，尽管内核似乎识别了电话，并将其用作网络设备，但我无法接收来自http-请求的任何数据包。

以下输出来自dmesg：

[  230.884554] rndis_host 1-1.1:1.0: dev can't take 1558 byte packets (max 1536), adjusting MTU to 1478
[  230.892791] rndis_host 1-1.1:1.0: RNDIS_MSG_QUERY(0x00010202) failed, -47
[  230.910356] rndis_host 1-1.1:1.0: eth1: register 'rndis_host' at usb-0000:00:1a.0-1.1, RNDIS device, 80:00:60:0f:e8:00
[  230.910382] usbcore: registered new interface driver rndis_host
[  241.853911] eth1: no IPv6 routers present

因此，这款手机被识别为eth1：

eth1      Link encap:Ethernet  HWaddr 80:00:60:0f:e8:00  
      inet addr:192.168.0.57  Bcast:192.168.0.255  Mask:255.255.255.0

点击一个互联网地址也是一样的：

但是，当我试图检索网页时，它不起作用(例如wget请求的输出)：

% wget www.google.com

Resolving www.google.com... 173.194.69.105, 173.194.69.106, 173.194.69.147, ...

所以我真的很惊讶，为什么这不起作用--希望这里的人知道我怎么能让它起作用。

提前谢谢。

好的，在稍微烦躁一下之后，结果发现问题是MTU的大小--将它设置为低于1100字节的值，这就完成了这个任务，而且连接现在几乎是完美无缺的。
