Please check the "positive-time-to-live" option in the "hosts" section of /etc/nscd.conf and make sure it's set to 3600. "restart-interval" is only of use if you have "paranoia" set to "yes". It's set to "no" by default, so "restart-interval" isn't even used. "man nscd.conf" for further info. I think these are where your problems are. I use nscd assiduously and it doesn't behave like that for me. If you really want to disable IPV6, edit /etc/modprobe.conf/blacklist.conf and add a line: blacklist ipv6 Go through any /etc/sysconfig/network-scripts/ifcfg-* scripts and if you see any "IPV6INIT=" or "IPV6_AUTOCONF=" lines, make sure they're set to "no". Finally, edit /etc/sysconfig/network and if you see a "NETWORKING_IPV6=yes" line, either remove it or set it to "no". Reboot and ipv6 goes bye-bye. Sidenote: Of course, 'twould be better if all ISPs did IPV6 correctly. We WILL need it eventually. ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer, C2 Hosting ricks@xxxxxxxx - - AIM/Skype: therps2 ICQ: 22643734 Yahoo: origrps2 - - - - All generalizations are false. - ---------------------------------------------------------------------- -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
