[ovs-discuss] [ovsdb] OVS DB connection refused by using ovsdb-client

Hi, all.

I install the OVS 2.6.0 by following the document[1]. Everything goes okay
but I meet a problem when I am using " ovsdb-client ".

I try to use " ovsdb-client dump " command to get information from OVS DB
and output is okay.

 I meet an exception when I try to use " ovsdb-client dump tcp: ".  Result shows below:

root at devstack:~/openvswitch-2.6.0# ovsdb-client dump tcp:
ovsdb-client: failed to connect to "tcp:" (Connection refused)

I think that OVS DB doesn't listen port 6640.

How do I ensure if OVS DB listen port 6640?

If OVS DB doesn't listen port 6640, what should I do?

Hope for anyone's reply. :)
