I really dislike the solution to switch back to bind9. So I searched for a solution and I found it.
For fixing this problem, apply this patch, posted on the Mantis bugtracker of MyDNS-NG. It's a bug in the current MyDNS-NG 18.104.22.168 version.
- Download latest version of MyDNS-NG (22.214.171.124)
- Extract archive
- apply the patch, or use VIM to modify 2 lines the file src/mydns/udp.c
- stop the running MyDNS (/etc/init.d/mydns stop)
- make install
- start MyDNS (/etc/init.d/mydns start)
After applying this patch I'm able to answer UDP-queries in IPv6 and there's no stack smashing any more. I'm using 2 servers (Ubuntu 10.04 x64 and 9.04 x64) and this patch works.
For those who having .nl-domains, you can use the SIDN DNS-check (https://www.sidn.nl/over-nl/aanvraag...ent/dns-check/
) to verify the usage.
@till: I hope MyDNS will still be available in the upcoming versions of ISPconfig3.
