[ovs-discuss] How to use the the function "snoop" in OVS ?

[張ふ渏]

Hi,
    Now I use the command "ovs-ofctl snoop [bridge_name]", and the ovs provide the error "failed to connect to socket(Connect reset by peer)". Then I am looking up the directory "usr/local/var/run/" and not find the file of bridge.snoop.However, I find the file bridge.snoop in the directory "usr/local/var/run/openvswitch",but the file's length is 0bytes.  What is wrong with it ?
Thanks!
SuSan~
