Public needs multicast tools for Linux
Ross Golder
compiled in 96/97 against dynamic libraries such as libc.so.4 !? I can't
seem to recompile them from source, for various reasons. For example,
'mrouted' throws up errors related to missing header files and such.
So, my questions are :-
1) Where can I get some recent Linux v2 binaries/compilable source for
things like 'mrouted', 'sdr' and 'vic/vat'? Preferably glibc compatible.
2) Assuming I can get mrouted to work, how can I join multicast groups
from my fixed-address ISDN dial-up? Do I need to open/close a tunnel
each time I bring the line up?
If the answer to 1) is 'you can't', is there anyone out there interested
in discussing what would be required to get these tools up-to-date. If
it's discussed in simple enough terms, with enough references, I should
be able to pick up enough to do something. I'd be willing to provide
services (mail list/web site/CVS etc) for such a project, if anyone else
is interested.
My motivation for this is so that other low-budget users like me,
without a corporate budget and/or a Solaris machine handy can take
advantage of MBone broadcasts. I run Linux via ISDN from my home office,
and have been interested in getting some kind of Mbone feed for ages. My
ISP (Nildram) is v cool IMO, but they don't have a feed. They used to,
but if I recall they found that none of their customers used it so they
dropped it.

Ross, finally learning about multicast.

I have gotten all sorts of mbone crap to compile after a bit of fighting
with tcl and tk on their silly little requirements, and I do remember
getting vic, vat, rat, and nv? was it? to compile.
Some time ago, I sent out a note concerning how to compile mrouted with
glibc. I specifically remember having to edit some header file and I
notified GNU of their deficiency. It's not too terribly bad, it just
takes time.
I am not sure I understand your second question, but if it is a fixed
address, you'll want to fire up mrouted when your link comes up. Then,
mrouted will likely nail your link up. You may end up fighting a losing
battle with mrouted because of the flood-and-prune effect. The solution I
found to be most effective was to use a 2500 at my end and run pim-sm over
the link. This provided the best answer after fighting for weeks over the
issue.

I'm following some instructions by Julian Highfield, but still having a
few problems.

Fair enough. I'd anticipated controlling the link manually anyway.

A 2500? Cisco router? Expensive, aren't they. I mean more than your
average home user's budget.
