I added a few service definitions (domain, xmpp-server, sftp-ssh) to the freedombox-setup git repository.

For the record, I can't see anything there either. I have seen occasional problems in my own testing when the IP address changes, but nothing so obvious as it just stopping to work. I think there must be a cache of lookups to avoid flooding the network with UDP packets - maybe if a lookup gets tried while the box is rebooting, the wrong thing gets cached for a while? If it happens again, I would be interested in distinguishing between the lookup failing vs. succeeding-but-wrong-ip. You can generally work this out from "ping" output. Meanwhile, I have been digging into issues with avahi and IPv6. Upstream releases have slowed over the last few years. :( I found that Windows Vista and up have LLMNR, a similar protocol, and there are unapplied Avahi patches to add support. Older Windows support NetBIOS - this also pretty much works out of the box if you install samba on the freedombox, but without the ".local" extension, and it's IPv4-only. And Linux machines need to edit nsswitch.conf if they are to look up those names. Still found nothing for Android yet. :( Tim ___ Freedombox-discuss mailing list Freedombox-discuss@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/freedombox-discuss

Hm, your client machine needs libnss-mdns, and avahi-daemon needs to be running on the freedombox... if the daemon stops responding, the address will no longer work. It would be worth checking the logs, perhaps? > > Is Bonjour in Debian? Is it the same as zeroconf? > > Still wonder about this one. :) "Bonjour" is the brand name of the Apple library that implements the two standards mDNS and DNS-SD, which together are two-thirds of "Zeroconf" networking. Bonjour is shipped out of the box on OS X (and I believe iOS), and is bundled with iTunes on Windows. The equivalent client library in Debian is libnss-mdns, which is a dependency of the main desktop environments (I think). https://en.m.wikipedia.org/wiki/Zero_configuration_networking So I was raising the point that not all Windows desktops will be able to find .local addresses without installing Bonjour, which might be important. On mobiles, iPhones should work, but I have not found a solution for Android (unless you build your own app). This sucks, but it is still the most user-friendly way I have yet found for getting people onto the web interface when you don't know the IP address of the box. I want to look more into the Microsoft upnp protocols to see if there's something that works for Windows. And I think Android support is quite important given the way things are going. But Mac and Linux users are sorted. :) Hope that helps, Tim ___ Freedombox-discuss mailing list Freedombox-discuss@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/freedombox-discuss

I would expect this behaviour as this is probably a virtual Web server in apache (or any webbserver) configured just for jwchat. If you check http at Wikipedia you'll see that the client sends the wanted server name as parameter "host: " in the GET request to the Web server. This is used to select the right Web server. The solution with mDns is probably the most useful one, and not only for this. > In short: > > - set up the freedombox's hostname as normal > - install avahi-daemon on it > - point your desktop system (with libnss-mdns installed) at http://fbx.local/ or similar. Yes, this is what I would do for an easy installation without the need to configure the local name server in the LAN(in the home router). The DHCP client in the freedombox should also publish its preferred name and then the LAN router usually uses that in all name resolutions in the LAN too. But if not, mDns is also used. > Windows support needs more to get going - you can install Bonjour, which is Apache-licensed. > > Tim /Anders ___ Freedombox-discuss mailing list Freedombox-discuss@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/freedombox-discuss
