Get ejabber installation from
http://www.process-one.net/downloads/ejabberd/2.1.10/ejabberd-2.1.10-lin...

Usual install and get:

i downloaded ejabberd-2.1.9 and compiled it successfully on windows 7 platform.
when i started ejabberd, i encountered trouble.
i can not get through the following function.

add_iq_handler(Component, Host, NS, Module, Function, Type) ->
case Type of
no_queue ->
Component:register_iq_handler(Host, NS, Module, Function, no_queue);
one_queue ->
{ok, Pid} = supervisor:start_child(ejabberd_iq_sup,

I am migrating my ejabberd server to a new server. I am keeping the same hostname so don't need to do the host name conversion. On the 2.0.5-1.1 machine I did a
ejabberdctl backup /tmp/ejab1.backup
I then sent that file to my new server running 2.1.5-3+squeeze1build0.11
and got the disco_publish table error - which I tried the workaround, but then got a

{aborted,{no_exists,http_poll}} error. Any ideas how to get past this or a better way to copy my database from the old 2.0 server to the new 2.1 server?

I've tried to install both 2.1.9 and 2.1.10 mac installers, but they both fail at the post-install script. Manually trying to run /bin/start from the terminal also doesn't work (it just stalls for several minutes, then launches safari with a failure page).

Anyone else having this problem?

Hi folks.

I've tried umpteen config mods and still don't seem to have a working server so, here I am, hoping for some help.

The system is a fresh install of ubuntu 11.10 server.

I installed the server with apt-get install ejabberd. I edited /etc/ejabberd/ejabberd.cfg to include this...

There's a DNS A record for the server, and the router is configured to forward 5222, 5269 & 5280 to the server machine.
