avahi-autoipd assigns an IPv4 link-local address in the 169.254/16 subnet. The time at which avahi-autoipd runs depends upon your system's network configuration. Network interfaces can be configured to only use DHCP, only use a static IP, or only use Avahi. But sometimes systems are configured to always run avahi-autoipd on an alias network interface (e.g., on "eth0:avahi"). > 2nd question: how can I look up the ip addresses that are assigned > to mylaptop.local (mylaptop should just be the local host name in > /etc/hosts on 127.0.1.1 on a debian system, right?) Run /sbin/ifconfig to find out how your network interfaces are configured. I'll leave your other questions for someone else to answer (because I don't know that much about MDNS side of Avahi).

I've recently been asking some questions on the irc channel. But as they got a little longer, I thought it might be better to just ask them here again: --- hi guys. I was looking for a way to get pidgin/libpurple working with avahi+ipv6. but then I realised, that I'm lacking some basic knowledge about avahi :) first question: I think I remember having the avahi-daemon running which assigned an ipv4 address on a new alias interface. when does this happen, when not? I also found this avahi-ipauto thingy, but it does not seem to be running for this avahi-ip4ll stuff to assign a 169.254.0.0/16 adress -169.254.0.0/24 and 169.254.254.0/24 (if I remember right) 2nd question: how can I look up the ip addresses that are assigned to mylaptop.local (mylaptop should just be the local host name in /etc/hosts on 127.0.1.1 on a debian system, right?) 3rd question: when exactly is avahi-dnsconfd needed and why? Is my assupmtion right, that I need this thing, if I want to use applications that are not utilising avahi (for instance a normal ping tool) and I want to reach mylaptop.local with that? 4th question: so an application that uses the libavahi can tell the avahi-daemon to announce a certain service with the specified port. which ip addresses would/should the avahi-daemon be announcing then? 5th question: what has to be kept in mind when using avahi with ipv4+ipv6 or ipv6 only? read this article in the german linux maganzine 03/06. at the end it is saying that for ipv6 stateless autoconfiguration, avahi-dnsconfd is necessary. sounds plausible because of the lack of a dhcp server. but why is this not the case for avahi with ipv4? --- Cheers, Linus _______________________________________________ avahi mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/avahi
