我是网络新手。我正在尝试通过以太网将嵌入式 Linux 连接到我的 Ubuntu 12.04.3 LTS。
我已将嵌入式系统配置为使用静态 IP 地址 (192.168.9.119)。
我在我的 Ubuntu 上添加了一个 eth1 接口，并将静态 IP 设置为 192.168.9.118。
嵌入式 Linux 通过以太网直接连接到我的 eth1，但是不起作用。
我的 ifconfig：
eth0 Link encap:Ethernet HWaddr 00:25:64:f8:7a:7a

SSH 错误消息（我认为它对你没用但我还是放了它）：
ssh: connect to host 192.168.9.119 port 22: No route to host
你知道哪里出了问题吗？谢谢
编辑：这是正常的吗？
user@linux:~$ ethtool eth1
Settings for eth1:
Cannot get wake-on-lan settings: Operation not permitted
No data available
route -n（在嵌入式设备上）：
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.6.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
192.168.9.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1
0.0.0.0 192.168.6.1 0.0.0.0 UG 0 0 0 eth0
现在，在 Ubuntu 上执行 arp -n 和 route -n ：
user@linux:~$ arp -n
Address HWtype HWaddress Flags Mask Iface
192.168.200.120 ether b8:ac:6f:b5:90:61 C eth0

192.168.200.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
答案1
你自己布线吗？看起来你遇到了布线问题eth1
