Probably not. ovs-ofctl is a controller too, just a short-lived one. > I've also been trying to detect the source of my problems by > debugging OpenvSwitch in runtime.

Thank you for all your > help, and for all your hard work making this awesome program! OVS doesn't really have a "debug mode". I guess that you are trying to follow the OVS log messages as they are emitted? The easiest way to do that is probably "tail -f /var/log/openvswitch/ovs-vswitchd.log". The "less" program is also useful since the F command does something similar to "tail -f". Have you tried the "ofproto/trace" command? It is the most valuable debugging tool for flow tables that I know of. It is documented in the ovs-vswitchd manpage. _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
