[Bug 656916] New: Disabling IPv6 in YaST2 does not disable IPv6
https://bugzilla.novell.com/show_bug.cgi?id=656916 https://bugzilla.novell.com/show_bug.cgi?id=656916#c0 Summary: Disabling IPv6 in YaST2 does not disable IPv6 Classification: openSUSE Product: openSUSE 11.3 Version: Final Platform: i586 OS/Version: openSUSE 11.3 Status: NEW Severity: Normal Priority: P5 - None Component: YaST2 AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: wadei@ntlworld.com QAContact: jsrain@novell.com Found By: --- Blocker: --- User-Agent: Opera/9.80 (Windows NT 5.1; U; en) Presto/2.6.30 Version/10.63 YaST2 > Network Devices > Network Settings Unchecking "Enable IPv6" should disable IPv6, but it does not, even after rebooting. DNS client still sends AAAA requests. I added ipv6.disable=1 to the list of kernel parameters in /boot/grub/menu.lst to stop this behavior. Reproducible: Always Steps to Reproduce: 1. See Details above 2. 3. Actual Results: DNS client sends AAAA request even after IPv6 was allegedly disabled. Expected Results: DNS A only. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

This is IMHO dhcp-client issue ...
No, it isn't a dhcp-client issue ;-) It is basically a duplicate of bug #632530 -- a difference in the kernel behavior between "ipv6.disable=1" and "disable_ipv6=1". (In reply to comment #0)
Actual Results: DNS client sends AAAA request even after IPv6 was allegedly disabled.
Expected Results: DNS A only.
No. The query is not the problem. A getaddrinfo with hints.ai_family==AF_UNSPEC is fine and queries both, A and AAAA records, whether IPv6 is enabled or not. You can ask for AAAA records over IPv4. $ host -t AAAA www.kame.net 203.178.141.194 Using domain server: Name: 203.178.141.194 Address: 203.178.141.194#53 Aliases: www.kame.net is an alias for orange.kame.net. orange.kame.net has IPv6 address 2001:200:dff:fff1:216:3eff:feb1:44d7 I'll attach some test results to bug #632530, that was reported earlier and provides concrete symptoms. Please continue there. *** This bug has been marked as a duplicate of bug 632530 *** http://bugzilla.novell.com/show_bug.cgi?id=632530 -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
