[icecast] Multiple Mountpoints Problem

Hello,
I've searched far and wide on the net and the only thing I've come up
with is that no one has ever had this problem.
I'm running Icecast 1.3.12 and the latest liveice on a Slackware 8.1
box. The idea here is that I need to stream a live source in multiple
bitrates. I am having a problem that is just about going to send me
back to Shoutcast.
I have set up two ENCODER_STREAM_SETs in my liveice.cfg, one on
mountpoint live24, one on mountpoint live48 (I've tried different names
too, like 24 and 48, low and hi, etc). If the option mount_fallback is
set to 1, connecting to *any* mountpoint on the icecast server will play
a stream with whatever parameters are set in ENCODER_STREAM_SET 0,
*even* if I connect to the mountpoint specified in ENCODER_STREAM_SET 1.
If I set mount_fallback to 0, and then try to connect to the icecast
server, *NO* streams work, even if I connect to the mountpoints
specified in the ENCODER_STREAM_SET lines.
If I may, let me include my icecast.conf and my liveice.cfg. I'm
starting to wonder how anybody does this at all; these problems are so
strange and I don't have confidence that I'm going to get an answer,
because it seems the question has never been asked or answered before.
Thanks in advance for any help you can offer. Included config files
follow.

# These describe the maximum number of simultaneous connections allowed.
# When reached, the server will refuse access.
# There is a builtin bandwidth measuring tool inside the icecast server,
# and when icecast thinks that it is using more than "throttle" MB/s,
then
# no clients or sources will be allowed until the bandwidth usage goes
back
# down below the limit. Use this with caution, since the bandwidth
measurement
# is in no way an exact science.

####################################
# This is a experimental feature, at best.
# When it does not work, it will put the whole stream out of synk on the
client
# side, and you will get a big mess.

streaming at
# all. It's turned off by default, cause it creates chirps
in the

sent to
# the client and the directory server. %s will be
# substituted for the actual filename.

############# Server IP/port configuration (IMPORTANT)
#########################
# If no hostname is specified, icecast will listen on all available
interfaces,
# i.e INADDR_ANY. This is probably what you want.
# If you want icecast to _only_ listen on a specified ip, then change
the
# "hostname" parameter. The "port" parameter is rather self-explanatory.
# As of icecast 1.3, all connections use port 8000. Admins, encoders,
clients,
# the whole thing. So no more messing with 3 different ports in the
firewall
# rules.
# The server_name can currently ONLY be specified here, and ONLY when
you start
# the server. Changing it later on will not have the desired effect.
# The server_name specifies the hostname of the server, don't set it to
an ip,
# and don't even THINK about setting it to a hostname not pointing to
your ip.
# - WARNING - WARNING - WARNING - (important, get it?)
# It is VERY important that this server_name does actually resolv to the
ip you
# are running your server at. If not, BAD THINGS<tm> will happen.
# E.g localhost is definately probably not what you want :)
# Using your ip will probably work.. but it will look nicer with your
hostname.
# The problem is that if you specify something that doesn't resolve to
yourself,
# then virtual host support will get fscked up, and default server
action
# might not work either.
# Also, changing the port here will not affect the server when doing a
'rehash'
# since binding to a port is done only once, when the server is started.
# server is started.
# Users on dialup connections with dynamic ip:s are in trouble here, I
know.
# You will just have to live without the virtual hosts support, cause
there is
# no portable way of getting all the ip:s the process is binding to.
Either
# edit this file before starting icecast and fill in the current ip, or
just
# live with it. Setting the value to "dynamic", will tell the icecast
server
# that there is no reliable hostname for this machine.
#
# you can now use multiple ports. the default port is the first one
defined.
# define PORT, and PORT+1 for shoutcast compatibility.

########################
# In icecast servers prior to the 1.3 release, you could run a icecast
# server as a relay for another icecast server, simply acting as a
# client on the other server and serving the local clients. This was
# of course a neat way of increasing the number of possible listeners
# for your broadcast. You could build a tree-like structure of relays
# and broadcast to 1000 listeners without problem with the originating
# stream on a cable modem or whatever.
# In icecast 1.3.0 and above, we make this procedure much simpler.
# If you want to relay a stream from another server, simply add an
# alias for that server. Say you want to relay the broadcast originating
# from my machine (laika.linux.tm:8000/laika), on your machine, do this:
# alias laika http://laika.linux.tm:8000/laika
# What happens is that when a listeners connects to your server and
# requests the /laika stream, then your icecast server will connect
# as a client to my machine, and then feed my stream to the listener.
# All subsequent requests for /laika will use the same feed (i.e only
# one connect will be made to my machine). Icecast will automagically
# shut the link from my machine down when no one is listening. I.e
# no bandwidth will be wasted.
# The old functionality (i.e adding a more or less static relay) is
still
# there, but you have to do it from the admin console. Just do
# relay pull http://laika.linux.tm:8000, and that will be accessible as
# http://your_machine:port/laika.linux.tm:8000/ (you can change this
with
# the -m option to relay pull.
# There is also a possibity to do it the other way around, starting at
# the originating server. Just do "relay push <source_id> host:port",
and
# your stream will be relayed to the remote server.
# In theory, this should enable virtual host support, cause you can
# specify an alias like so:
# alias http://virtual.host.com:port/whatever /something
# This will make all requests to virtual.host.com:port/whatever use the
# stream /something. This is not really thorougly tested, but it should
# work if your server_name is correctly set, and the client is sending
# the valid Host: <host:port> http header.

############################ Kick Relays
######################################
# How long to keep aliased sources when no clients are left listening to
it.
############################
kick_relays 10
############################ Transparent proxy
################################
# This is somewhat equivalent to making _all_ request to aliased
sources. So
# instead of adding an alias for all streams in the world, turn on the
# transparent proxy support. Using this on a server that has streams of
it's
# own can be quite tricky, and then, as usual it is _very_ important
that
# the server_name is correct.
# Most mp3 playing clients have support for a http proxy
# (afaik x11amp and winamp do, anyway). If listeners set your machine as
this
# proxy, and you turn on transparent_proxy, then when a client requests
# http://whatever.com:port/whatever, then your icecast server will
connect
# to whatever.com and feed the whatever-stream to the client. All
subsequent
# request for this stream will use the same feed, just as if it was an
alias.
# When running icecast with your own broadcasts, then you should turn
this off,
# or anyone can bring your network down with a lot of relaying connects.
# Don't turn this on if you don't have a server_name set
############################

<p>######################## Access Control Lists
##################################
# Perhaps you don't care who connects to your server, but I guess most
people
# do. Icecast has 2 different ways of keeping people out. The first is
using
# libwrap (tcpd, tcp wrappers, whatever you want to call it). It is a
separate
# library written by Wietse Venema that over the years has become more
or less
# a security standard in Unix. It should compile on every sane and
unsane unix
# platform, and perhaps other platforms as well, I don't know.
# libwrap uses the files hosts.deny and hosts.allow, usually found in
/etc
# or /usr/local/etc. You probably have to be root to edit these files.
# Try the man pages for tcpd and hosts_access for more information.
# There are 4 different icecast control thingies to use in
hosts.deny/allow.
# First just "icecast", which controls _all_ connections, and kick in
before
# anything is written or read on the socket. If a connection is denied
here
# then it's bye bye. If it is allowed then depending on the type of the
# connection (admin/client/source), the controls "icecast_client",
# "icecast_admin", "icecast_source" describe who gets in.
# So to deny all clients except those matching *.se, add
# "icecast_client: ALL EXCEPT *.se" to hosts.deny. There are millions of
# variations on how to build a complete defence, and it's quite simple
too.
# libwrap is a very powerful tool, consult the manpages for more
information.
####
# The second way (which is always available) is using icecast's internal
# acl lists. The functionality is the same, but it is not as powerful
when it
# comes to configuration and flexibilty as libwrap.
# You can specify acl rules either here in icecast.conf, or using the
# admin console. The syntax in icecast.conf is:
# allow <all|client|source|admin> <hostmask>
# deny <all|client|source|admin> <hostmask>
# So, using the same rule as above (allowing only clients from *.se)
# deny <client> *
# allow <client> *.se
# When using the internal acl rules, you need to specify a policy.
# This rule kick in when no allow or deny rule affects a connection.
# If you set acl_policy to 0, then connections who are not allowed by
any
# allow rule will be denied, and the other way around if you set it to
1.
