>Description:
If one tries to set up mydns (dns/mydns) port to bind on any IPv6 address it will fail.
>How-To-Repeat:
add a 'listen' line where you specify an IPv6 address to your mydns config file and try to run mydns. it will fail to bind on the given address and port as there's a bug in the original code.
>Fix:
only two lines has to be patched in the ./src/mydns/listen.c file in order to fix this problem, see the attached patch file. running mydns with this patch it smoothly binds and replies to DNS queries via IPv6.
