I've not tested the kernel argument, but that may be preferable. You are right. I have just installed a regular F12 kernel and ipv6 is compiled in as a module. I may be misremembering but I remember reading some threads where people were having problems with DNS and ipv6 (with F10 or F11) and they were unable to blacklist ipv6 because it was a not a module. So either Fedora backtracked on the compilation of ipv6 or my memory sucks... Blacklisting ipv6 may not be enough to disable it completely; ipv6 can still be loaded with insmod/modprobe. If you add install ipv6 /bin/true to the blacklist entry, it will not load at all. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
