我最近在Beagle Bone Black上安装了Ubuntu 13.04。这个图片：
https://rcn-ee.net/deb/flasher/raring/BBB-eMMC-flasher-ubuntu-13.04-2013-10-08.img.xz
该微控制器允许通过USB在主机PC（版本12.04（精确）（64位），内核Linux 3.2.0-56-通用）和BeagleBone之间共享Internet连接，因此我将其配置为如下所示：
BeagleBone黑色：
ifconfig usb0 192.168.7.2
route add default gw 192.168.7.1
主机电脑：
sudo su
#eth0 is my internet facing interface, eth3 is the BeagleBone USB connection
ifconfig eth2 192.168.7.1
iptables --table nat --append POSTROUTING --out-interface eth0 -j MASQUERADE
iptables --append FORWARD --in-interface eth2 -j ACCEPT
echo 1 > /proc/sys/net/ipv4/ip_forward
在Internet连接正常工作之后，ping 8.8.8.8我得到了以下结果：
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
64 bytes from 8.8.8.8: icmp_req=1 ttl=47 time=4.63 ms
64 bytes from 8.8.8.8: icmp_req=2 ttl=47 time=4.68 ms
64 bytes from 8.8.8.8: icmp_req=3 ttl=47 time=4.57 ms
64 bytes from 8.8.8.8: icmp_req=4 ttl=47 time=4.58 ms
^C
--- 8.8.8.8 ping statistics ---
4 packets transmitted, 4 received, 0% packet loss, time 3005ms
rtt min/avg/max/mdev = 4.578/4.620/4.682/0.063 ms
为了也配置DNS，我也键入了，echo "nameserver 8.8.8.8" >> /etc/resolv.conf但是不幸的是ping google.com，经过几秒钟的计算后，我得到了ping: unknown host google.com
所以-我知道，这种解决方案不好，但是对于本届会议来说，它可能行得通，但行不通。而且，BBB和PC都使用resolvconf。老实说，我不知道如何使用该程序配置网络...我尝试/etc/network/interfaces像这样在Beagle Bone Black上进行更改：
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
#auto eth0
iface eth0 inet dhcp
# Example to keep MAC address between reboots
#hwaddress ether DE:AD:BE:EF:CA:FE
# WiFi Example
#auto wlan0
#iface wlan0 inet dhcp
# wpa-ssid "essid"
# wpa-psk "password"
# Ethernet/RNDIS gadget (g_ether)
# ... or on host side, usbnet and random hwaddr
# Note on some boards, usb0 is automaticly setup with an init script
# in that case, to completely disable remove file [run_boot-scripts] from the boot partition
auto usb0
iface usb0 inet static
address 192.168.7.2
netmask 255.255.252.0
network 192.168.7.0
#broadcast 192.168.7.3
gateway 192.168.7.1
dns-nameservers 8.8.8.8 8.8.4.4
但这没有帮助。
我不知道该怎么办。请帮忙。

重要的是-与BBB共享Internet的PC可在大学网络中工作，该网络比普通的家庭网络复杂得多-会导致DNS解决问题吗？重要的是-如果我在resolv.conf.d / head中设置了一个有意义的名称服务器（它像8.8.8.8一样启动并运行），然后键入ping google.com，则机器会计算一段时间，然后返回错误未知主机。如果我设置了一个废话地址，那肯定是行不通的（即123.123.123.123），则会立即返回错误。
使用BB（而不是背面），您的命令可以正常运行。我刚刚更换域名服务器127.0.0.1与域名服务器<我的DNS IP地址>，和主机名解析工作...
