Workaround: disable avahi-daemon, by running system-config-services as root. You may turn this off with setting publish-aaaa-on-ipv4=no in /etc/avahi/avahi-daemon.conf. See avahi-daemon.conf(5) for details. Lennart, Thanks for info! The name 'publish-aaaa-on-ipv4' does not suggest anything about setting IPv6 address, but whatever works is good to me. Hmm? "AAAA" refer to IPv6 address records in DNS/mDNS. Note that Avahi is not involved in IPv6 network configuration. It just listens to changes of it, but doesn't modify anything. If you have trouble with that then Avahi is not the project to file bugs against. |
Description of problem: In a local network with IPv6 router broadcasting "Router advertisement" packets, avahi-daemon sets IPv6 address even with use-ipv6=no. If this is expected behavior, please advise a way to stop avahi from setting IPv6 address. If not expected, please fix it. Version-Release number of selected component (if applicable): avahi-0.6.27-2.fc14.x86_64 How reproducible: always Steps to Reproduce: 1. modify /etc/avahi/avahi-daemon.conf "use-ipv6=no" 2. restart avahi-daemon. 3. With an IPv6-capable router, on the same network, broadcasting IPv6 "Router advertisement" packets periodically. Actual results: avahi-daemon sets IPv6 address upon receiving IPv6 "Router adv." packet. This was announced in /var/log/messages, eg. Jan 14 00:22:56 taiwan avahi-daemon[1339]: Registering new address record for 2005:123:456:789:xxx on eth0.*. Expected results: With use-ipv6=no, avahi-daemon should ignore IPv6 "Router adv." packets. Additional info:
