Problem with ecmh/multicast on RealROOT?
![[de]](/s/countries/de.gif) Shadow Hawkins on Thursday, 19 February 2004 10:55:18
Maybe it's just my fault, but my POP (RealROOT) isn't even answering MLD Queries from ecmh (checked it also with ethereal, but here's my dump):

Problem with ecmh/multicast on RealROOT?
The ecmh on that POP detected MLDv2 packets on your link/tunnel and no v1 packets. Can you show the tcpdumps ? (-Xns 1500) and skip the irrelevant packets svp

Maybe it sends MLDv2 packets (not that I've seen any), but doesn't ecmh send his own MLDv1 queries, which should be answered (sorry, but I don't know anything about MLD). BTW, I'am using USAGI Kernel 2.4.24 on my router, maybe that's the problem?!
Anyway here is my dump:
