从 Ubuntu SSH 到嵌入式 Linux

从 Ubuntu SSH 到嵌入式 Linux

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
      inet addr:192.168.200.58  Bcast:192.168.200.255  Mask:255.255.255.0

嵌入式设备上的 ifconfig(不关心 eth0):

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

现在,在 Ubuntu 上执行 arp -n 和 route -n :

user@linux:~$ arp -n
Address                  HWtype  HWaddress           Flags Mask            Iface

user@linux:~$ route -n

192.168.9.0     0.0.0.0         255.255.255.0   U     0      0        0 eth1

答案1

你自己布线吗?看起来你遇到了布线问题eth1
