Hi
I have a problem with ipV6 (nslookup takes 10..20 seconds) if i disable
ipv6 in busybox only it is solved, so i leave ipv6 in the kernel and uclibc
enabled.
The toplevel setting for ipv6 is also still enabled.
When i do a clean build with the config files i saved before the cleaning, i
noticed that the ipv6 is back on in busybox ...
I suspect the toplevel ipv6 setting is causing this and seems to modifie the
busybox setting for ipv6..
If everything is build, i change the busybox setting and do a rebuild of
busybox to get it right.
So its anoying i can not use the config files in the first build pas.
What can i do about it ?
Johan

Hi
Ok, i can live with it as it is now ( doing bb rebuild )
If i would know another way to disable ipv6 i would be happy.
I tried to build the kernel without IPv6 , but that does not solve it.(or
pass ipv6.disable=1 on the kernel cmd line)
I browsed some of the bb sources to see if there was a way to disable ipv6
through some /etc/? config file but not find anything related.
It seems to be a known problem one some distros too,
(http://faq.aslab.com/index.php?sid=63600&lang=en&action=artikel&cat=58&id=1
24&artlang=en)
The resolv.conf is updated by dhcpc with the router addr (192.168.1.1) if i
change it to 195.238.2.21 manually i don't see a delay with a nslookup (this
is no option)
Some routers pass the external dns server addresses (would not be a problem)
,some act as a dns is in my case...
Meanwhile i am still open for a solution...,as i would like to keep ipv6 for
future requirements.

Yes, so we can use the same defconfigs for both ipv6 and !ipv6:
git grep IPV6 package/busybox/busybox.mk package/busybox/busybox.mk:ifeq
($(BR2_INET_IPV6),y) package/busybox/busybox.mk:define BUSYBOX_SET_IPV6
package/busybox/busybox.mk: $(call
KCONFIG_ENABLE_OPT,CONFIG_FEATURE_IPV6,$(
package/busybox/busybox.mk: $(call
KCONFIG_ENABLE_OPT,CONFIG_FEATURE_IFUPDOW
package/busybox/busybox.mk:define BUSYBOX_SET_IPV6
package/busybox/busybox.mk: $(call
KCONFIG_DISABLE_OPT,CONFIG_FEATURE_IPV6,$
package/busybox/busybox.mk: $(call
KCONFIG_DISABLE_OPT,CONFIG_FEATURE_IFUPDO
package/busybox/busybox.mk: $(BUSYBOX_SET_IPV6)

Well, you could naturally remove the IPv6 handling in busybox.mk, but why do
you enable IPv6 support in uClibc if you don't want to use it?
