![]() Then, save the file, make it read-only, and restart firestarter chmod -w user-pre Set the contents of the file to the following $IPT -A INPUT -p udp -dport 5353 -d 224.0.0.251 -j ACCEPT You will need to chmod u+w this file to make it writable before editing. The current work around is to edit /etc/firestarter/user-pre as root. This may be configurable in the next version. If you are using Firestarter all multicast traffic is blocked. If you can turn your firewall off and this fixes the problem, then it is definitely the firewall. Then it is possible that your firewall is blocking the zeroconf communication. If you are running a firewall and you are having problems like ping flute.local Now any computer on the network can use hostname.local in place of an ip address. Now each computer with avahi-daemon (or mdnsresponder) installed will identify itself on the network as hostname.localįor example, my computer flute, identifies itself as flute.local Assuming the remote Ubuntu computer responded to the VNC connection request, then Zeroconf is properly resolving the local host name.From another computer, launch a VNC client and enter myhost.local as the host name, replacing the "myhost" portion with the host name deduced from step 1 above.Check the first two boxes under Sharing and configure the Security settings as desired. Open Terminal and deduce the local host name from the prompt (e.g., to System > Preferences > Remote Desktop.The following steps can be used for testing: Zeroconf is installed and configured by default in the Desktop version of Ubuntu 9.04. Sharing music - Rhythmbox, Banshee, iTunesĪutomatic discovery of VoIP clients in your local network - Ekiga.Also be aware that it is trivially easy to spoof an mdns. Although zeroconf is a fairly efficient protocol the admin may not want the extra traffic. Note, if you are not doing this on your own network you may want to talk to the Network Admin first. For example you may have an IP address allocated by DHCP and use DNS to resolve address on the web, but still use the hostname.local from MDNS (Multicast DNS) to resolve the addresses of other computers on the LAN. It works happily along side traditional tools. It also requires no configuration (apart from the installation). But the decentralised zeroconf method is appropriate in some situations, for example ad-hoc networks. Traditionally most of its work is done by DHCP and DNS. ![]()
