Isn't it supposed to be ipv6_enable=NONE I could be wrong. andrew clarke wrote: On Sun, Nov 21, 2004 at 09:58:39AM -0500, Michael W.

I'm running 4.10 on this machine (same as the OP), with ipv6_enable=NO in /etc/defaults/rc.conf and nothing to override it in /etc/rc.conf. Yet the machine booted with IPv6 enabled. Only when I disabled IPv6 in the kernel did v6 stop trying to happen. This also had the effect of speeding up name resolution by Mozilla and friends, which IIRC was the OP's issue in the first place. -- Chris Hill [EMAIL PROTECTED] ** [ Busy Expunging | ] ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: turning off IPv6 support in BSD
Hello, If you turn off ipv6 support either in the kernel or via rc.conf will it be possible to load ipfilter as a module vs. compiling it in to the kernel? I turned off ipv6 in the kernel on a 5.3 box, but ipfilter was unable to load the module was not found because it depended on ipv6. Thanks.
