I was running IPv6 tunnelbroker on Linux quite happily till now, but it went crazy in the weekend probably because it hit some limit in the kernel. With more than 500 tunnels tunnelbroker lost connection to the LAN, "ping6 -I eth0 ff02::1" stopped working etc. I cleaned up a tunnels a little bit, removed dead ones, got number of tunnels down to the 460 and all is working without any problem again. I hit some multicast related limit in kernel probably, but which one? And how to increase it? -- Hasso Tepper Elion Enterprises Ltd.
