[Pkg-icecast-devel] Bug#475889: icecast2: Binding on random port

[Vincent Riquer]

Package: icecast2
Version: 2.3.1-6.1
Severity: important


Since last update, Icecast does not work correctly with IPv6 nor IPv4.

It runs successfully (no messages on standard output, nor in the logs, even in
loglevel 4 (debug), but it is not possible to connect to it (Connection refused).

When run with strace, one can see that instead of binding to the port specified 
in the listen-socket directive, it binds to a random port (0) :

bind(4, {sa_family=AF_INET6, sin6_port=htons(0), inet_pton(AF_INET6, "::", &sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, 28) = 0

In /etc/icecast2/icecast.xml, I have the following :
    <!-- You may have multiple <listener> elements -->
    <listen-socket>
        <port>8000</port>
        <bind-address>::</bind-address>
    </listen-socket>

I also tried with
    <!-- You can use these two if you only want a single listener -->
    <port>8000</port>
    <bind-address>2a01:5d8:52f4:3ae9:21a:70ff:fea3:44ab</bind-address>

which didn't help.
