Problem with recursion for windows bind for Teamviewer

[Ondřej Surý]

Hey,

BIND 9.16 is in security-and-critical-only mode, so this won’t get fixed in any case.

However, your message is incomprehensible. If you want to get anything fixed, we will need more clarity in the report - describe your setup (clients, recursive servers, authoritative servers) and properly describe the communication between those. Logs from the failing servers are absolute minimum. Perhaps (annotated) tcpdump (wireshark) dumps would be also helpful.

> Teamviewer (and maybe other sites too) when you do the recursion when no answer under 1000ms it tries again which is trigged by client windows (not the one running bind) which also tries again for a answer this seems to causes the bind server not to give a answer but it tries and tries then Teamviewer works so Teamviewer DNS is doing a delayed reply which seems to be causing a problem for bind for windows because I tested bind in Ubuntu having DNS forward for teamviewer.com to it and Teamviewer loads faster.
