http://bugzilla.novell.com/show_bug.cgi?id=894889 --- Comment #2 from Andreas Schwab <schwab@suse.com> --- That's not the bug. The bug is that ntpd cannot cope. getaddrinfo correctly orders the IPv4 address first, so other services will work fine. Incomplete IPv6 connectivity is still very frequent. -- You are receiving this mail because: You are on the CC list for the bug.

That's not the bug. The bug is that ntpd cannot cope. getaddrinfo correctly orders the IPv4 address first, so other services will work fine.
Where can I log in to reproduce and debug this?
Incomplete IPv6 connectivity is still very frequent.
This is not incomplete IPv6 connectivity, it is a broken setup that I think MUST NOT happen this way. Even if there is a problem in sntp here, I think we're also looking at a bug somewhere either in the network code or in your network configuration. -- You are receiving this mail because: You are on the CC list for the bug.

Marius, any ideas on how it could have happened that this machine has a route into the internal IPv6 network, but no according IPv6 address? -- You are receiving this mail because: You are on the CC list for the bug.

BTW, I am not even sure the hang was due to IPv6, because I see no evidence for that in comment 0 and I can't reproduce it on my 13.1 with the ntp package from Factory and after manually removing all global IPv6 addresses from eth0. -- You are receiving this mail because: You are on the CC list for the bug.
