Hm...

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 ?

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.

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)
1>

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 :

<iq type='get'
    to='kael@jabber.se'
    id='disco1'>
  <query xmlns='http://jabber.org/protocol/disco#info'/>
</iq>

<iq from="kael@jabber.se" to="kael@example.net/Gajim" id="disco1" type="result">
<query xmlns="http://jabber.org/protocol/disco#info">
<identity category="pubsub" type="pep"/>
<feature var="vcard-temp"/>
<feature var="http://jabber.org/protocol/profile"/>
<feature var="http://jabber.org/protocol/commands"/>
</query>
</iq>

<iq type='get'
    to='kael@jabber.se'
    id='iq1'>
  <profile xmlns='http://jabber.org/protocol/profile'/>
</iq>

    </x>
</iq>

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.
