mdns-repeater ============== mdns-repeater is a Multicast DNS repeater for Linux. Multicast DNS uses the 188.8.131.52 address, which is "administratively scoped" and does not leave the subnet. This program re-broadcast mDNS packets from one interface to other interfaces. It was written primarily to be run on my Linksys WRT54G which runs dd-wrt, since my wireless network is on a different subnet from my wired network and I would like my zeroconf devices to work properly across the two subnets. Since the mDNS protocol sends the AA records in the packet itself, the repeater does not need to forge the source address. Instead, the source address is of the interface that repeats the packet. USAGE ----- mdns-repeater only requires the interface names and it will do the rest. For example, the dd-wrt standard installation defines br0 for the wireless interface and vlan1 as the WAN interface, I would use: mdns-repeater br0 vlan1 You can also specify the -f flag for debugging, which prints packets as they are received. You are free to modify the code to repeat whatever traffic you require, as long as you abide by the software license.
