Specify ipv6 address to listen on to

Submitted by birger on Thu, 2008-07-10 19:02

Hi all,
I have multiple IPv6 addresses on my machine and I want ejabberd only listen on a specific one. How do I do that? I tried various forms of the ip,{...} configuration parameter but that didn't work.

Thanks for help.

Try setting the IPv6 address in tuple form

Submitted by mfoss on Sat, 2008-07-12 11:01.

Let's say I want c2s of port 5222 to listen only in the IPv6 address: ::ffff:127.0.0.1

To configure ejabberd, you need to express that IPv6 address in tuple form. How to know the correct value? This way:

$ erl
Erlang (BEAM) emulator version 5.6.3 [source] [smp:2] [async-threads:0] [kernel-poll:false]

Eshell V5.6.3  (abort with ^G)
1> inet_parse:address("::ffff:127.0.0.1").
{ok,{0,0,0,0,0,65535,32512,1}}

Now that you know the correct value, edit ejabberd.cfg and specify the IP address as a tuple:

{listen,
 [
  {5222, ejabberd_c2s, [
                        inet6,
                        {ip, {0,0,0,0,0,65535,32512,1}},
                        {certfile, "/etc/ejabberd/ssl.pem"}, starttls,
                        {access, c2s},
                        {shaper, c2s_shaper},
                        {max_stanza_size, 65536}
                       ]},
...

When I login with my Jabber client, I see in ejabberd.log:

=INFO REPORT==== 12-Jul-2008::12:15:37 ===
I(<0.265.0>:ejabberd_listener:114) : (#Port<0.439>) Accepted connection
{{0,0,0,0,0,65535,32512,1},48887} -> {{0,0,0,0,0,65535,32512,1},5222}

If you try this, can you pease report that it works correctly? I mean that ejabberd only listens in that IPv6 address, and clients can connect correctly, etc. Thanks

mmm... seems correcectly,

mmm... seems correcectly, ejabberd listens only in that IPv6:

netstat -apn | grep beam
____________cut__________________

but bug/feature request "Allow to specify IP address in string format in the Listen section" still present:

& any ipv6 XMPP-client ?

IP can only be specified as tuple, not string

Right, the two feature requests that I mentioned are still present in ejabberd, that's why I mentioned them.
Right now the only way to specify an IP address is providing the tuple.
