Multicast from Orinoco wireless stations

It seems that some Orinoco 802.11 base stations send multicast packets on 224.0.1.76/2313 (IAPP.MCAST.NET). By sending a multicast join (opening a socket with netcat or other tool) to this group, one can discover other base stations on multicast-enabled portions of the Internet, such as the academic networks CA*net, ESnet etc. There is administrative access to these units via telnet and http. The group should probably be filtered at an administrative boundary as a matter of principle. -- Andrew Daviel, TRIUMF, Canada Tel. +1 (604) 222-7376 security () triumf ca
