“无法访问目标主机”和ARP通过LAN返回任何地址

我目前正在试图通过networking掩码为255.255.255.0两台机器上设置LAN，但是我试图在它们之间进行通信时收到以下消息;

 [root@alpha ~]# ping 192.168.0.249 PING 192.168.0.249 (192.168.0.249) 56(84) bytes of data. From 192.168.0.248 icmp_seq=2 Destination Host Unreachable From 192.168.0.248 icmp_seq=3 Destination Host Unreachable From 192.168.0.248 icmp_seq=4 Destination Host Unreachable --- 192.168.0.249 ping statistics --- 6 packets transmitted, 0 received, +3 errors, 100% packet loss, time 5175ms 

在其他专用机器上反过来也是如此。 我对我做错了什么，我已经重新启动并重新启动了多次networking服务，仍然没有运气。

正如你从下面看到的，ARP不返回任何LAN地址，但是它应该显示这两个地址。 IPTables被禁用，普通的公共IP将允许ping。

Dedi＃1的详细信息：

• 在linux上透明网桥的ARP问题
• xen项目 – 桥接界面显示2个MAC
• 定向ARP请求没有到达网桥接口
• Broadcom网卡，Cisco ASA和ARP请求冲突
• Linux不回复一个ARP请求
