Two of them have returned NXDomain, and this result was sent back to a client. I think this behaviour is wrong, client shouldn't get NXDomain when other non-nxdomain replies from nameservers exist. This was fixed once (see commit http://git.kernel.org/cgit/network/connman/connman.git/commit/src/dnsproxy.c?h=1.30&id=0439194ed0c5a90f61dbef86d9a51307764da2d7), but then was refactored in later commits ----- Vladimir Pavljuchenkov _______________________________________________ connman mailing list connman@connman.net https://lists.connman.net/mailman/listinfo/connman
