[Openwrt Wiki] Multicast Dns Daemon. Sometimes the bridge between your lan and your wlan will block multicast packets. The mdns protocol is meant to resolve host names to ip addresses within small networks that do not include a local name server.

The mdns service is used to advertise the availability of services that are provided on the system. The mdns service is used to advertise the availability of services that are provided on the system. The appropriate client sends a multicast into the network while asking which network participant matches up with the host. The igmpproxy adds routes and rules to the kernel which cause the kernel to forward these multicast udp packets received on the wan to the lan where they are received by the original requester. For multicast dns (mdns) and dns service discovery to function, mdns must be deployed on all of the systems that will participate in mdns. Edit the hosts line in: Multicast dns is used to locate a device or service by name on a small local network without using a preconfigured name sever i.e dns. Think rendezvous (tm) for the rest of us. Description mdnsresponder (also known as mdnsd on some systems) is a daemon invoked at boot time to implement multicast dns and dns service discovery. To install mdns on linux:
If necessary, install the package as follows:. First you need to install the package. Multicast dns is used to locate a device or service by name on a small local network without using a preconfigured name sever i.e dns. Instead of querying a name server, all participants in the network are directly addressed. The mdns service is used to advertise the availability of services that are provided on the system. Multicast dns (mdns) is a protocol aimed at helping with name resolution in smaller networks. This is a wrapper around apple\'s mdnsresponder source to enable it to deal with multiple clients making it more like the mdnsresponder for os x. It reflects mdns queries and responses among multiple lans, which allows you to run untrusted iot devices in a separate lan but those devices can still be discovered in other lans. Think rendezvous (tm) for the rest of us. Mdnsresponder listens on udp port 5353 for multicast dns query packets. When an mdns client needs to resolve a hostname, it sends an ip multicast query message that asks the host having that.
