在 beaglebone black 中使 ip 靜態後無法訪問網際網路

我試圖在我的 Beaglebone 黑色中使我的 IP 靜態。為此，我遵循本教程。根據教程進行更改後，我的 /etc/network/interfaces 文件如下所示：-

# 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 static

address 192.168.24.38
network 192.168.24.0
broadcast 192.168.24.255
netmask 255.255.252.0
gateway 192.168.25.10

# Example to keep MAC address between reboots
#hwaddress ether DE:AD:BE:EF:CA:FE

# The secondary network interface
#auto eth1
#iface eth1 inet dhcp

# 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
iface usb0 inet static
   address 192.168.7.2
   netmask 255.255.255.0
   network 192.168.7.0
   gateway 192.168.7.1

重新啟動我的 Beaglebone black 後，我可以使用 command 看到我的 IP 是靜態 ip ifconfig。這是命令的輸出ifconfig

但現在我無法訪問網際網路。所以。請告訴我設置中的錯誤在哪裡。謝謝

如建議的那樣，命令的輸出ip route是：-

 default via 192.168.25.10 dev eth0 
   192.168.7.0/30 dev usb0  proto kernel  scope link  src 192.168.7.2 
   192.168.24.0/22 dev eth0  proto kernel  scope link  src 192.168.24.38

命令的輸出ping -c1 google.com是

ping：未知主機 google.com

命令的輸出 netstat -nr

Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
192.168.7.0     0.0.0.0         255.255.255.252 U         0 0          0 usb0

輸出 ping 和 netstat 命令確認路由一切正常。然而 DHCP 也提供 DNS/解析器設置數據。DNS 解析失敗。

請編輯您的 /etc/resolv.conf 並將其填寫為：

nameserver 8.8.8.8

ping google.com 應該可以正常工作。

稍後與您的公司交談，並詢問他們的內部域 (yourdomain.xx) 和他們的名稱伺服器的 IP (localnameserver)

並將其更改為：

search yourdomain.xx
nameserver localnameserver
