Hello all,

I build a vserver and give the interface configuration, but the vserver can't connect
to the host. The ping command doesn't work properly. I use the packet capture tools.
It seems that the vserver can't receive the reply messages. The detail interface configuration
information is below:

Interface configuration:

echo "eth4" > /etc/vservers/xxx./interfaces/0/dev
echo "192.168.1.2" > /etc/vservers/xxx/interfaces/0/ip
echo "24" > /etc/vservers/xxx/interfaces/0/mask

The ip address of host os is "192.168.1.1".


and then I start the vserver xxx, enter the vserver xxx, try to ping the ip address
"192.168.1.2", and the result is below:


bash-3.2# ping 192.168.1.2
PING 192.168.1.2 (192.168.1.2 ) 56(84) bytes of data.

--- 192.168.1.2 ping statistics---
6 packets transmitted, 0 received, 100% packet loss, time 5007ms



I use the packet capture tools, the ping request and reply appeard both, it is so strange,
the result is below:
