Debian wheezy 可以到达本地网络但丢包，无法访问更广泛的互联网

正如标题所示。我可以ping通本地网络，但是会连续有10个数据包丢失，并且连接速度很慢。无论是 ping IP 还是通过域名，都无法访问网络外部的任何内容，包括默认网关。

使用逐步分析这里，在步骤 2 之后我无法执行任何操作。网络上的所有其他设备使用相同的以太网电缆都可以正常工作。

我想问题有两个：为什么本地网络丢包，为什么无法到达外部网络？这是一台我最近才使用的旧电脑，似乎被篡改过很多次。

IP 路由（eth0 是我用于网络的路由）：

ip route
default via 192.168.1.1 dev eth0
10.0.0.0/16 dev eth1  proto kernel  scope link  src 10.0.0.2
192.168.1.0/24 dev eth0  proto kernel  scope link  src 192.168.1.97

Ip addr - .97 是静态的，.117 由 dhcp 设置

ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 00:07:32:8f:ec:be brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.97/24 brd 192.168.1.255 scope global eth0:0
    inet 192.168.1.117/24 brd 192.168.1.255 scope global secondary eth0
3: eth1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN qlen 1000
    link/ether 00:07:32:8f:ec:bf brd ff:ff:ff:ff:ff:ff
    inet 10.0.0.2/16 brd 10.0.255.255 scope global eth1

答案1

存在重复的 IP 问题 - 在路由器的 IP 绑定设置中，我为系统设置的静态 IP 已注册到不同的 MAC 地址。
