Epeios + mod_profile

I'd wish to install Epeios so that I can then run mod_profile with Openfire.

I've tried to install Epeios (without mod_profile first) on Ubuntu Feisty with erlang-1:11.b.2-4ubuntu1 and erlang-dev installed from APT, but unsuccessfully.

Here's the full installation :

$ cd /opt
$ sudo mkdir /opt/epeios-1.0.0
$ sudo chown -R kael epeios-1.0.0/
$ chmod u+rwx -R epeios-1.0.0/
$ svn co https://svn.process-one.net/ejabberd-modules/epeios/trunk epeios-1.0.0
...
Checked out revision 494.
$ export EPEIOS_ROOT=/opt/epeios-1.0.0/
$ cd epeios-1.0.0
$ vim sys.config.mk

[
%% Please, use an absolute lib path matching your actual configuration
%% Epeios container configuration:
{epeios, [{epeios_name, "epeios.domain.tld"},

Apparently, the translate.beam file is not detected whereas it exists :

$ locate /opt/epeios*/translate
/opt/epeios-1.0.0/lib/.svn/text-base/translate.beam.svn-base
/opt/epeios-1.0.0/lib/.svn/prop-base/translate.beam.svn-base
/opt/epeios-1.0.0/lib/translate.beam
/opt/epeios-1.0.0/ebin/translate.beam

Wondering what I'm missing.

Any idea anyone ?

Thanks.

Here we see that the stringprep module couldn't load its shared library, stringprep_drv.so. Maybe setting the environment variable EJABBERD_SO_PATH would help?

Epeios + mod_profile : How to set up User-Profile ?

Submitted by kael on Sun, 2008-02-03 16:29.

Thank you very much for the clue.

The EPEIOS_ROOT path was correctly set, but the epeios_lib_path was uncorrectly set to :

{epeios_lib_path, "/opt/epeios-1.0.0/lib/darwin-x86"}

instead of :

{epeios_lib_path, "/opt/epeios-1.0.0/lib/linux-x86"}

I then copied mod_profile.erl in /opt/epeios-1.0.0/modules, launched epeios :

$ priv/epeios.start 
Erlang (BEAM) emulator version 5.5.2 [source] [async-threads:0] [kernel-poll:false]
Eshell V5.5.2  (abort with ^G)

and Epeios works and appears in the component session interface. Thank you very much. :)

Now, I'm searching how to use mod_profile with Epeios, following xmpp://jabber.se mod_profile :

I queried disco#items and disco#info on example.net, kael @ example.net, epeios.example.net and kael @ epeios.example.net with both namespaces (the one used in the XEP and the other user by jabber.se), but I can't find how to upload a profile.

In sys.config.mk, I added a line :

{mod_profile, []},

But it doesn't seem enough, does it ?

What am I missing ?

And a last question : how to launch Epeios without process output, with a "nohup ... &" like ?

Cheers.

N.B.: I'm a not pro of Ejabberd and Erlang, though.

Hm...

Submitted by legoscia on Wed, 2008-02-06 09:09.

Hm… I really don't know much about Epeios, but I'm not sure if it's possible to use it for something like mod_profile, which handles requests on behalf of users. It's theoretically possible, but the protocol that Epeios uses (XEP-0114) doesn't allow a component to install an IQ handler in the server, as you've already noticed; even making the component respond on its own address would need some black magic, I guess…

I prefer "screen" and detaching ☺ Running erl with the -detached option might work, though.

Looking for ejabberd docs?
