This is your interpretation of the AI_PASSIVE code. getaddrinfo() has always returned multiple adresses, *even in Lenny*, and your code is supposed to cycle through all of them. Nothing in the POSIX function says it should return only one entry. This would even be impossible in Squeeze, as the bindv6only=1 is the default, which means it is not possible to bind to both IPv4 and IPv6 with a single socket. By the way the getaddrinfo code is identical in glibc and eglibc, so please stop blaming eglibc. -- Aurelien Jarno GPG: 1024D/F1BCDB73 aurel...@aurel32.net http://www.aurel32.net -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
