We've got 3 local (relatively fast, very stable) windows dns servers. In an effort to reduce network traffic internally and externally by limiting DNS queries where reasonable, I'm testing DNSServerLimit is set to ONE. I feel like this will generally be sufficient, if for some reason a DNS server is temporarily down, assp should be smart enough to use another (right?) - I don't think this will be a problem in our environment. I'm taking the weekend to confirm that suspicion.
The 3 dns servers are listed in DNSServers in ASSP, use local DNS is unchecked, DNSResponseLog is checked, and DebugSPF is checked (for testing purposes). Things >>appear<< to be working fine, but when I applied these changes, I got this in the logs: Jun-14-15 09:57:42 Info: DNSResolverSend: caller: Net::DNS::Resolver::Base, 468, sourceforge.net Jun-14-15 09:57:42 Info: Name Server x.x.x.53: ResponseTime = 2 ms for sourceforge.net Jun-14-15 09:57:42 Info: DNSResolverSend: caller: Net::DNS::Resolver::Base, 468, sourceforge.net Jun-14-15 09:57:42 Info: Name Server x.x.x.52: ResponseTime = 2 ms for sourceforge.net Jun-14-15 09:57:42 Info: DNSResolverSend: caller: Net::DNS::Resolver::Base, 468, sourceforge.net Jun-14-15 09:57:42 Info: Name Server x.x.x.51: ResponseTime = 1 ms for sourceforge.net *Jun-14-15 09:57:42 Info: DNSresolverTimeS timed out* *Jun-14-15 09:57:42 Info: NO_NAME_SERVER_GIVEN - closing existing DNS sockets* *Jun-14-15 09:57:42 Info: DNSresolverTimeS timed out* *Jun-14-15 09:57:42 Info: NO_NAME_SERVER_GIVEN - closing existing DNS sockets* *Jun-14-15 09:57:42 Info: DNSresolverTimeS timed out* *Jun-14-15 09:57:42 Info: NO_NAME_SERVER_GIVEN - closing existing DNS sockets* So ASSP is testing all 3 servers as it should to decide which one should be used until the next test or failure. But what does "DNSresolverTimeS timed out" mean? Why does it say NO_NAME_SERVER_GIVEN? And I am now seeing: Jun-14-15 10:01:06 Info: DNSresolverTimeS timed out Jun-14-15 10:01:06 Info: NO_NAME_SERVER_GIVEN - closing existing DNS sockets frequently. ------------------------------------------------------------------------------ _______________________________________________ Assp-test mailing list Assp-test@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/assp-test
