ovs-ctl will create this before it starts any daemon, and the distro packages also create it, so it's usually not necessary. > - Can ovsdb-server create a symlink to db.sock to avoid requiring > "--remote=punix:/usr/local/var/run/openvswitch/db.sock" in what seems to > be the default invocation?

I think that ovs-dpctl-top is probably not used very much. Maybe bugs have crept in because no one is using it. If you find the problem and fix it, please pass it along. _______________________________________________ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
