The documentation for the IPV6_V6ONLY sockopt indicates that this is a boolean value controlling whether or not an AF_INET6 is V6ONLY or not.The Linux man page for ipv6 further clarifies that /proc/sys/net/ipv6/bindv6only, which Debian has set to "1" specifies the default value for IPV6_V6ONLY.If Courier specifically sets IPV6_V6ONLY to int 0, it should override Debian's behavior and allow the application to function normally:int on = 0; if (setsockopt(s, IPPROTO_IPV6, IPV6_V6ONLY, (char *)&on, sizeof(on)) == -1) perror("setsockopt IPV6_V6ONLY");
Splendid. We have our solution.I'm in the middle of pulling all the innards out, and hopefully putting them back, sometime soon, but this is going to be the next thing on the chopping block.
